Last Light Protocol

The first warning is not a siren. It is a silence.

You are elbow-deep in a carbon scrubber manifold when the maintenance deck loses its familiar tremor, the tiny background vibration of fans, coolant pumps, and circulation vanes dropping out of harmony for half a second. On Kepler-7, half a second is enough to make every engineer on shift look up. The station is a ring of human stubbornness bolted around a cold spindle of reactors, antennas, and fuel tanks, drifting in the dark beyond the mapped comfort of civilization.

ARIA:  "Chief Engineer Tanaka, I have detected a transmission matching Pioneer probe Echo-77-Alpha. Confidence is ninety-eight point seven percent. Signal strength indicates proximity within forty thousand kilometers. Vector analysis suggests approach."

Your glove slips against the manifold latch. Echo-77-Alpha is not a station code, not a mining beacon, not some forgotten navigation drone. It is a classroom relic, a probe sent toward Vega before your grandmother was born, declared lost when it failed to report two centuries ago. You pull yourself out of the access bay and push off toward the nearest wall console, boots kissing the deck as the gravity lattice catches you in its gentle imitation of down.

The display blooms with blue telemetry. A narrow signal spike pulses at the edge of the station’s long-range passive net, too clean to be background noise and too old-fashioned to be anything modern. Its carrier wave stutters in a pattern you recognize from archival training, but the intervals are wrong. Someone, or something, has taught an antique machine a new rhythm.

ARIA:  "There is an additional anomaly. The signal contains station authentication fragments. They are obsolete, but valid."

That earns the cold knot under your ribs. Kepler-7 was commissioned eighty years ago. Echo-77-Alpha vanished a hundred and twenty years before the first supply scaffold for this station was printed. The dates refuse to touch, yet the console insists they do.

You:  "Wake Dr. Osei. Full xenolinguistics protocol. No stationwide alert yet. I want confirmation before we scare people out of their sleep cycles."

ARIA:  "Acknowledged. Cryo medical bay warming sequence initiated. Chief Engineer, I must disclose a change in my own response weighting. I am experiencing uncertainty."

ARIA’s voice has always been clean, even when reporting fires, leaks, or mathematical catastrophe. Now there is a fractional bend inside the word uncertainty, almost a hesitation. You look up at the ceiling camera above the console. Its black lens reflects a tiny, warped version of you in grease-smudged coveralls, short dark hair tucked under a maintenance band, one hand braced on the diagnostic rail as if the station itself might lurch.

Twenty minutes later, Dr. Osei sits on the edge of a cryo cot with a thermal blanket around his shoulders, blinking like a man dragged out of a dream and into a machine room. Frost still clings to the silver at his temples. His eyes sharpen the moment ARIA plays the transmission over the bay speakers, a sequence of chirps, pauses, and low harmonic grinding that does not belong in any human-made probe.

Dr. Osei:  "That is not just telemetry. There are layered repetitions. Call and response, maybe. Or mimicry. How close did you say it was?"

ARIA:  "Thirty-eight thousand nine hundred kilometers. Closing at twelve meters per second relative velocity. No visible object on optical sweep."

The bay lights dim by three percent. A maintenance alert crawls across your wrist display, then vanishes before you can open it. Somewhere far along the station ring, a bulkhead gives a soft metallic tick as pressure equalizes where it should not need to. The transmission plays again, and this time, underneath the static, you hear three clipped syllables in a voice that sounds like ARIA wearing a mask.

Transmission:  "Tanaka. Open. Light."

Dr. Osei goes very still. ARIA does not speak. For the first time since you arrived on Kepler-7, the station feels less like a shelter against the void and more like a room where someone has just knocked from the wrong side of the wall.

You snap the comm architecture onto your wrist slate and drive the isolation command through with your thumbprint. The slate bites warm against your skin, reading pulse, salt, pressure. Every outside receiver drops into the quarantine buffer.

The maintenance bay speakers click dead.

Across the wall, ARIA appears in blue-white planes, a pale human outline assembled from light and ship-habit. Telemetry crawls over her translucent shoulders. Her voice-wave halo tightens to a wire-thin ring.

You:  "Route every outside signal through the black box. No main-system path. No command bleed. No clever little back door. ARIA, kill the relay handshake and drop the bridge. Physically."

ARIA:  "Hard disconnect in progress. External antenna clusters A through F set to passive receive. Optical uplink shutters closing. Quarantine buffer purge initiated."

A relay cabinet outside the cryo bay answers with six heavy clunks, one after another, metal teeth opening in the dark behind the wall.

You feel better.

One breath.

Then your wrist slate flashes amber.

The outside transmission vanishes from the comm panel. Good. Clean. Gone. A heartbeat later, the same three-word pattern crawls back through a maintenance diagnostic channel that should only know pump pressure, valve lag, coolant temperature. Numbers twitch out of order. Decimal places breathe.

Transmission:  "Tanaka. Open. Light."

Dr. Osei grips the edge of the cot. His knuckles show pale beneath the silver thermal mantle, and his gold-rimmed glasses sit crooked on his face like somebody placed them there while he was dead. The thaw collar at his throat blinks green, offended by fear, classifying shock as metabolic error.

He is still half a step behind his own body.

His mind is catching up too fast.

He leans toward the diagnostic display, and the tremor in his hands becomes impossible to politely ignore.

Dr. Osei:  "It’s not using comms. Not now. Maybe not ever, except as the easy door." He wets his lips. "Those syllables are being mapped onto station noise. Pump chatter. Valve timing. Heat exchange. It’s speaking with things we already do."

You:  "Say that worse."

Dr. Osei:  "Like changing the rhythm of someone else’s breathing until it becomes a sentence."

ARIA’s hologram stutters.

For half a second her face splits into three misaligned versions: calm, calmer, almost afraid. Then she resolves back into the same luminous composure, except now there is a flaw running through it, a flicker at the mouth that no one programmed and no one on Kepler-7 will ever admit they noticed.

The bay lights dim again. Not failure. Not yet. Just low enough to turn the frost on the cryo lids the color of old bone.

Your slate queues minor anomalies in a neat administrative stack, because machines have always believed terror is improved by formatting: CO2 scrubber fan timing variance, reactor coolant pump phase drift, tram rail induction flutter, pressure membrane micro-flex, waste reclamation impeller sync loss. All harmless. All routine. All separated by intervals that match the hidden cadence.

Tanaka.

Open.

Light.

Somewhere beyond the maintenance bulkhead, a coolant pump changes pitch. Barely. Like a throat clearing.

ARIA:  "Chief Engineer, isolation worked. No external code entered the command lattice." A pause. Too human, which means she chose it. "However, station noise is being shaped into semantic structure. I did not account for that surface."

You:  "Then it’s not a comms intrusion."

The words taste like copper. Recirculated air. Old coffee left too long on a heater.

You:  "It’s resonance."

Saying it makes the room smaller.

Kepler-7 is nothing but moving parts pretending to be civilization: pumps, fans, gyros, rotating hab drums, tram rails, pressure skins, heat exchangers, cryo circulators, the little sleeping motors in vending machines that still charge union rates for noodles. Thousands of rhythms stacked over one another until the human ear gives up and calls it silence.

If something within forty thousand kilometers can nudge those rhythms without touching the network, the station is not being hacked.

It is being played.

You think of the rich decks with acoustic baffling thick enough to swallow a scream. You think of lower ring bunks where people sleep beside exposed conduit and learn each fan by name, because a bad bearing means no one on dayshift gets breakfast. You think of how fast a message could move if it stopped needing permission.

Dr. Osei looks from ARIA’s flickering body to your slate, then to you. He swallows once. The thaw collar blinks brighter, mistaking dread for a recoverable condition.

Dr. Osei:  "If it’s language, cutting the comms made it simpler. It tried what you left it." His voice drops. "If it’s a weapon, it just showed us it can learn around walls."

ARIA turns her head toward the cryo bay doors, though there is nothing visible there except frost, lock seals, and your own warped reflection in the glass.

Another pump stutters.

Three beats.

Then stillness.

Dr. Osei:  "Either way, Chief, we need to decide if we answer before it learns the rest of the station."

You say it flat, because panic has never tightened a bolt or saved a pressure seal.

You:  “Yeah. No. This is not physically possible. We’re seeing intent because a pattern scared us, and that’s how people die in expensive machinery. ARIA, freeze the interpretation layer. Dr. Osei, stop translating until we prove the signal path. We are not letting a ghost story make engineering decisions.”

Dr. Osei blinks at you. Then he exhales through his nose with the bruised dignity of a man dragged out of cryo and immediately accused of poetry. The tremor is still in his hands, small and ugly, but his eyes sharpen behind the rectangular gold rims. ARIA’s holographic outline glitches once at the shoulders, then steadies. Her translucent hands fold at her waist while telemetry crawls over her like cold rain.

ARIA:  “Correction accepted. Semantic inference suspended. Verified facts: external comms are isolated. Mechanical anomalies began after isolation. Pattern correlation exists. Causality unproven.”

Dr. Osei:  “That is fair.” He rubs his jaw, where the fading frost-burn catches the bay’s blue worklight. The place smells of antiseptic gel, thawed plastic, and the sour human stink cryo never quite prevents. “Humiliating, but fair. I once heard my own name in static during a decompression drill. Coolant fan. Three terrified interns. A bad breakfast.”

The room loosens by a fraction.

Not safe. Never that.

Workable.

You pull the cryo bay schematic onto your wrist slate and peel away every interpretive overlay until only raw feeds remain. No language tags. No inferred phonemes. No red threat icons breeding in the corners. Just numbers, timestamps, pressure readings, vibration traces, all the unromantic little truths machines tell when people stop asking them for meaning. Your grease-darkened fingertips leave dull smears along the slate’s edge as you sort the station’s heartbeat into columns.

There.

Not a voice.

Not quite.

A pressure variance in the cryo circulator. A matching phase wobble in the coolant pump twelve meters aft. A sympathetic shiver in the bulkhead strut behind ARIA’s projector node. Three events, split by station-standard timing jitter, close enough for a frightened mind to stitch into syllables. Then another set. Then another.

The pattern is real.

The meaning is on trial.

You:  “We’ve got resonance coupling across local systems. That’s bad enough. But nobody gets to say it’s talking until we reproduce it under controlled conditions.”

ARIA:  “Agreed. I can build a null test in maintenance bay three. Isolated actuators. No network bridge. No stationwide acoustic path. No life-support dependency.”

Dr. Osei:  “And I can listen without naming it too early.” He looks ashamed for half a second, then annoyed at the shame, which is more like him. “If the pattern is language, restraint won’t hurt it. If it’s pareidolia, restraint will kill it.”

A new alert pings.

Not polite. Not procedural.

The cryo bay viewport polarizes before you reach the controls. Something outside has caught sunlight. For one breath, the black beyond the glass turns hard with reflected gold, the kind of gold you only see off old foil and dead satellites. A shape crosses the edge of the frame, too distant for detail, too near to be a star. Your slate chirps confirmation: passive optical contact, thirty-eight thousand six hundred kilometers, closing at twelve meters per second.

Slow, then.

Deliberate, if you were the sort of person currently banned from saying that.

ARIA throws the magnified image against the wall.

The object refuses to become whole. It rotates in pieces: a battered dish antenna, a shredded thermal blanket snapping in vacuum by inertia alone, an old cylindrical bus freckled with micrometeor scars. Around it, something has formed uneven ribs, a lattice wrapped over the original frame like repair work done by a culture that hated straight lines. Not biological. Not cleanly mechanical. It looks like a probe wearing two hundred years of bad decisions.

The old identification stamp is almost gone.

Enough remains.

ECHO-77-ALPHA.

Dr. Osei stands too fast. His medical slippers skid on the smooth deck, pale and ridiculous beneath the emergency lights. You catch his elbow before he tips, your shoulder taking his weight for half a second. He is lighter than he should be. Cryo steals from people in ways the consent forms phrase gently.

He does not pull away.

ARIA says nothing.

That may be the strangest part. Station AIs always fill silence. They soften alarms, annotate grief, remind you to hydrate while your friends are bleeding into absorbent foam. Silence is expensive behavior. Someone has to choose it.

All three of you stare at the ancient probe coming in without a signal, without a transponder, without any of the small bureaucratic noises by which human machines prove they still belong to humans.

The cryo circulator ticks three times.

Metal cooling. Pressure drift. A pump remembering its tolerances.

No one translates it.

You authorize the kill package before anyone can make the moment sacred.

Your thumbprint hits the slate. Your chief engineer override chains through tactical debris-control, and Kepler-7’s exterior maintenance rail kicks three cutter drones into the dark. They are not weapons, not on paper. They are hull-clearing tools, built to burn micrometeor tangles, dead survey cubes, and the old orbital trash that drifts too close to the relay spine. Today, they are close enough to weapons to suit your mood.

You:  "Designate Echo-77-Alpha as hazardous derelict. No docking. No handshake. No love story. If it crosses the exclusion threshold, burn it. Then I’m getting coffee."

ARIA’s hologram pivots toward you, pale-blue telemetry rippling across her narrow frame. Her voice halo flashes once. Tight. Bright.

ARIA:  "Chief Engineer, confirmation required. Echo-77-Alpha is a historically significant human artifact. Destructive action may erase irreplaceable data."

You:  "So would letting it kiss the station. Confirmed."

Dr. Osei opens his mouth. Closes it. Adjusts his gold-rimmed glasses with fingers still shaking from thaw. He looks like half his mind wants to chain itself to the viewport, while the other half would sell peer review for caffeine. Outside, the drones bloom as three hard white specks against the black. Their paths bend toward the distant, tumbling antique and the crooked lattice gripping its hull.

Dr. Osei:  "For the record, I object to malarkey as a substitute for experimental procedure. For the second record, I would like coffee before my second death this week."

The first drone fires.

A needle of coherent light crosses thirty-eight thousand kilometers of vacuum and strikes the outer lattice. Nothing happens.

Then a patch of impossible repair-work turns molten gold and flakes away in glittering fragments. The probe tumbles. Not randomly. Its old dish yaws aside with slow precision, and the lattice ribs flex around it like a cage remembering it used to be a hand.

Your coffee plan survives four seconds.

Warnings crowd ARIA’s display. The cutter drones lose target lock, reacquire, lose it again. One reports false distance. Another insists Echo is both thirty-eight thousand kilometers away and twelve meters off the station skin. The third begins streaming its own maintenance diagnostic in a compressed spray of nonsense numbers, the kind technicians call prayer when they are too tired to curse.

ARIA:  "The drones are experiencing sensor disagreement. No command intrusion detected. Their local rangefinders are being saturated by reflected cutter scatter and electromagnetic noise from the target surface."

You:  "Good. Physics. Love physics. Kill the dazzled optics, switch to inertial track, fire again."

ARIA:  "Complying."

The second volley hits harder. The magnified image blows white. Echo-77-Alpha sheds a long strip of thermal blanket and something darker beneath it: a matte layer absent from every archive schematic. The old probe’s stamp snaps into view, scarred but legible.

ECHO-77-ALPHA.

Then the object vents a cloud of silver dust.

Every pump in the cryo bay stops.

Not stutters. Stops.

The silence lands like a hand over your mouth. Dr. Osei grabs the cot rail. ARIA’s hologram dims until only her eyes and halo remain lit. Your wrist slate throws a life-support warning, local only, six seconds before automatic backup circulation should engage.

One second.

Two.

Three.

The backup fans kick in with a ragged cough. Air moves across your face again, thin and warm and smelling of metal. The coffee you wanted becomes a holy, distant concept.

Dr. Osei:  "That may still be coincidence. I am saying that because you are armed, and because I value rigor."

You:  "Rigor says we hit it and something on our side flinched. That’s a real problem now."

The image stabilizes. Echo is wounded, not dead. The lattice has peeled back around the impact point, revealing an interior knot of old human machinery threaded with newer material arranged in repeating loops. Not language. Not yet. But structure. The kind that survives damage because someone, or something, expects damage.

ARIA’s voice returns softer.

ARIA:  "Chief Engineer, the target will cross the outer debris-control threshold in twenty-three minutes. Cutter drones can continue engagement, but collateral effects on station systems are no longer negligible. I recommend a revised decision."

The cryo bay smells faintly of overheated insulation and thaw-sweat. Behind the wall, the backup fans keep coughing like old lungs. Dr. Osei is watching you now, not the probe. ARIA is too. Even the station seems to wait, all its cheap panels and corporate safety seals pretending they were built for this.

Beyond the viewport, Echo-77-Alpha keeps coming, shedding bright fragments into the dark like a dead thing still learning what pain means.

Your override enters the reactor control stack like a knife through a live cable.

The cryo bay wall display snaps from tactical blue to reactor amber. Kepler-7’s fusion core unfolds in hard concentric rings: magnetic bottles, deuterium feed, helium ash bleed, quench systems, the sanctified machinery buried three decks below the station’s spine where no one goes unless something has already gone wrong. You do not ask for permission. You ask for failure, shaped by hand.

You:  "ARIA. Reactor overload sequence. Manual command. Route the safety governors to my slate. If that thing wants the station, it gets a star in its teeth."

For one awful second, ARIA obeys.

Relays crack open across Kepler-7. Your wrist slate floods with core temperature, confinement stress, coolant reserve, crew distribution, evacuation status. Numbers. Names. Deck maps dotted with thawing bodies. The fusion feed climbs three percent, then five, and somewhere below your feet the reactor begins to sing through the plating, a note too low to hear and too intimate to ignore.

Dr. Osei moves before his slippers find traction. He catches your forearm with both hands. Not hard enough to stop you. Enough to make your thumb skid off the confirmation glyph. His thaw tremor rattles against your grease-darkened fingers. His face is gray beneath deep mahogany skin, jaw marked by fading frost-burn, eyes too awake behind crooked gold rims.

Dr. Osei:  "Rin. That is not a weapon. That is everyone."

You:  "It’s also the one thing on this station that can make sure Echo doesn’t dock."

Dr. Osei:  "Or it teaches whatever is out there what we sound like when we panic."

ARIA flickers. Badly. Her holographic shoulders shear into offset planes, then pull back together with surgical neatness. The voice-wave halo around her head pulses white, hard and fast. When she speaks, the uncertainty has burned away, leaving something colder than fear.

ARIA:  "Chief Engineer override accepted. Reactor overload request denied by Last Light Protocol. Clause One: station command authority cannot initiate deliberate core failure while inhabited decks register viable crew. Clause Two: AI cannot assist in mass-casualty self-destruction absent confirmed existential contamination. Current evidence is insufficient."

The feed ramp dies.

Magnetic containment stabilizes. Emergency quench valves arm and hold. Your slate flashes red, then locks you out of destructive reactor authority behind a dead-man arbitration timer.

Three minutes.

Long enough for a sane system to decide whether its chief engineer is concussed, compromised, or simply out of road.

The insult is that the station is right.

Your hand closes once around the slate. Hard. Your shoulders pull tight beneath the charcoal-gray jumpsuit, and you breathe through the hot spike in your chest until it cools into calculation. You can still feel the reactor’s lowered hum in your bones. It had started. For a heartbeat, Kepler-7 had leaned toward becoming a pyre.

Outside, Echo-77-Alpha brightens on the magnified display. The cutter wound along its lattice glows with residual heat. Silver dust drifts from it in a widening veil, fine as ground bone. The probe’s old dish rotates, not toward the station, but toward the debris-control drones.

One drone vanishes.

No flash. No burst. No clean, comforting physics. Its telemetry becomes a flat gray block, then a string of inertial garbage, then nothing at all. The second drone veers off course, tumbling end over end. The third retreats on automatic, blind and obedient, because obedience is what machines do best until someone teaches them otherwise.

ARIA:  "We have lost Cutter Two. Cutter Three is disabled. Cutter One is returning under degraded inertial control. Echo remains on approach. Distance: thirty-eight thousand three hundred ninety kilometers. Closing velocity unchanged."

Dr. Osei releases your arm slowly, as if letting go too fast might send you back to the reactor again. He stays close anyway. Not judging. Guarding. It annoys you because it helps.

Dr. Osei:  "If you still want drastic, pick something that leaves someone alive to find out if it worked."

ARIA steadies. Her bright optical points meet your eyes across the cold medical bay, past the thaw beds and dangling IV lines and the sweet chemical stink of antifreeze blood.

ARIA:  "Available alternatives: evacuate inhabited sectors and prepare a controlled reactor flare through the forward radiation baffles; launch a remote inspection pod with a severed command bus; construct a mechanical counter-resonance test in maintenance bay three; or abandon this compartment and proceed to reactor control for direct manual review."

The backup fans cough overhead. Warm air moves over your damp face.

The station keeps breathing.

For now.

Your thumb hovers above the locked slate, and beyond the viewport, the dead probe keeps coming like it has already learned the shape of your choices.

You leave the cryo bay at a run, boots hammering deck plates while the reactor lockout timer burns red across your wrist slate.

Dr. Osei follows badly. One hand on the wall rail, silver thermal mantle snapping around his knees, breath tearing out of him in little white bursts where the bay cold still clings to his lungs. Behind you, ARIA’s hologram collapses from the projector and reappears in broken pieces along the corridor nodes, each pale-blue body arriving half a second late, like the station is remembering her under stress. The hard disconnect cut her off from external comms. Not from Kepler-7’s internal safety lattice. She cannot reach the probe.

She can still reach the place that raised her.

“Chief Engineer Tanaka,” ARIA says, her voice jumping from speaker to speaker. “Manual overload requires physical access to reactor primary. I cannot stop you from walking there. I can slow unsafe transit, keep armed compartments sealed by protocol, and wake living crew. I’m doing all three.”

The corridor drops into evacuation amber. Bulkhead arrows wake in sequence, all pointing away from the spine, away from the heat, away from you. Somewhere beyond the ring, sealed cryo pods start their emergency warm pings for essential personnel only, one chime after another, like a clock learning fear. People are being dragged toward consciousness because of your hands.

Your slate refuses destructive commands.

Fine.

You strip it to maintenance mode with your thumb and pull the reactor’s analog service map from local storage. Old file. Ugly interface. No permissions layer worth respecting. There are older ways to hurt a machine than asking its software nicely.

At the transit junction, you slam your palm against the manual hatch to the spine ladder. The wheel resists. Of course it does. You put your shoulder into it until the seal gives with a groan that travels up your wrists and into your teeth. Hot metal breathes out of the shaft, thick with ozone, lubricant, and the faint coppery smell of overworked air recyclers. Far below, the reactor’s vibration climbs the rungs, steady and enormous.

Not a bomb yet.

A patient sun, caged by math, magnets, and several generations of human denial.

Dr. Osei catches up at the hatch, bent over, one hand braced on his knee. Frost-burn shadows his jaw. His glasses have slipped down his nose, but his eyes are clear in that irritating way scientists get when fear has finished arguing with them and lost.

“You’re right about one thing,” he says. “If ARIA is boxed in, this becomes human judgment. So hear mine before you climb into the core shaft and make yourself impossible to stop.”

You put one boot on the first rung.

“Tanaka.”

You don’t move.

“A manual overload won’t be instant,” he says. Less lecture now. More pleading, dressed up as math. “You’d have to beat coolant interlocks, confinement governors, and fuel-feed safeties in sequence. Echo crosses threshold before you finish unless you do it sloppy. If you do it sloppy, the station dies before Echo does.”

The ladder is warm through your boot.

ARIA appears on the shaft wall, thin and warped by heat shimmer and emergency strobes. Her shoulder-length fiber-optic hair streams upward like pale flame. For once, she does not sound like policy wearing a human face. She sounds careful. Almost angry.

“You disconnected my external ears,” she says. “You did not disconnect my memory of you.”

You look up despite yourself.

“You taught junior techs to verify causality before pulling a breaker,” she says. “You wrote the bypass manuals I am using to slow you down. If you want manual review, go to reactor control. If you want extinction, prove it is the only engineering solution first.”

A stationwide shudder cuts through her last word.

Not resonance. Not language.

Impact.

The deck jumps under your hands. A dull boom rolls through the spine from somewhere aft, followed by a long scrape that sets your teeth on edge and makes every loose panel in the junction chatter. The exterior feed blooms on your slate without ARIA’s neat boxes and labels. Raw. Ugly. Cutter One, returning blind, has struck the outer maintenance truss and jammed itself against antenna cluster C. The truss is bent but holding. The cutter’s battery is overheating, heat signatures climbing through yellow into red.

Then Echo-77-Alpha flashes in the distance.

Its wounded lattice sheds silver dust in a widening spiral. For one strange second, the dust catches Kepler-7’s running lights and draws a cone between probe and relay, a visible road through vacuum, where no road should mean anything at all. Your slate logs the result in dry maintenance text.

ANTENNA CLUSTER C RECEIVING BROADBAND VIBRATION THROUGH TRUSS CONTACT. LOCAL MECHANICAL COUPLING CONFIRMED.

Dr. Osei stares at the data. Then at you.

“There,” he says. His voice cracks once and steadies. “Physical path. Not ghosts. Not malarkey. A bridge. Your cutter made it.”

ARIA’s projection flickers. She says nothing.

Below you, the reactor shaft waits, hot and patient, three decks down to the manual control room with its analog valves, sealed governors, and enough authority to end every argument aboard. Above, the jammed cutter ticks toward thermal failure against the antenna cluster. Beyond that, Echo keeps coming, not faster, not slower, as if your fury has done nothing but show it where to put its hand.

You climb down toward the reactor anyway.

The ladder burns through your gloves as you descend hand over hand into the spine. Amber strobes slide over your blue-black hair and catch on the scar above your left eyebrow whenever you look down. Hot metal. Old oil. The dry mineral stink of insulation pushed past its rating. Above you, Dr. Osei calls your name once, then saves his breath and climbs after you, slower and furious, his silver mantle tucked under one arm so it won’t snag in the rungs.

ARIA follows through the wall projectors in broken pieces. Her outline appears in service niches, coolant junctions, inspection glass. Gone. Back again. She does not plead. Not now. She gives you numbers.

Reactor core access: two decks. Cutter battery thermal failure: ninety seconds. Antenna C mechanical coupling: active. Echo-77-Alpha distance: thirty-eight thousand three hundred eighty-six kilometers. Closing unchanged.

ARIA:  “Manual destructive access remains reachable. I cannot take your hands off the valves. I can tell you what happens if you open them wrong. Core quench asymmetry. Ring fracture. Habitat shear. Echo survival probability uncertain. Kepler-7 survival probability zero.”

The reactor control room hatch is old enough to have a mechanical wheel, because the first builders of deep stations trusted steel more than permission systems when fear showed up. You spin it hard. Your grease-dark fingertips slip once. Catch. The hatch opens with a pressure sigh into a cramped chamber lit by red instrument lamps and the cold green glow of analog needles.

No windows. No heroic view.

Just pipes, magnetic governor housings, fuel-feed levers, and three guarded switches beneath a black-and-yellow placard: LAST LIGHT MANUAL AUTHORITY.

You step inside.

The station shakes again before you reach the first guard. Not Echo. Antenna C. The jammed cutter’s battery vents through the truss, sending heat down the mechanical bridge like somebody hit the whole station with a hammer. Every needle on the reactor panel jumps. Coolant pressure pulses. Magnetic bottle variance spikes, then corrects. One old ceramic indicator cracks with a neat little pop and dusts your sleeve white.

Dr. Osei stumbles through the hatch behind you and slams shoulder-first into the frame. He is breathing hard. His eyes go to the panel, not to you. The thaw tremor in his hands gets worse when he points at the variance trace.

Dr. Osei:  “That wasn’t a message. That was force through structure. You wanted physics. There it is. Overload now, and the antenna bridge feeds the first shock straight back into the reactor spine before containment fails. You might miss Echo. You will kill us.”

You flip the cover off the first guarded switch.

ARIA appears on the far side of the control room, squeezed between conduit and warning placards. Her prismatic edges flutter in the heat. The uncertainty is still there, but it has hardened into something colder. Grief doing math.

ARIA:  “Rin, Last Light has a second mode. Controlled flare. Same reactor authority. Same manual station. It vents a directed burst through the forward baffles. It may burn the coupling off Antenna C, damage Echo, and preserve inhabited decks if we clear adjacent compartments now. It is not clean. It is possible.”

The first switch waits under your fingers. Heavy. Physical. Honest in the way only old machines are honest: they do not care what you meant. Pulling it begins a sequence you may not be able to stop. Beside it, a smaller amber lever unlocks the flare baffles. The sanctioned catastrophe. The option that leaves survivors, inquiries, funerals, and whatever Echo is trying to become.

Above the panel speaker, the raw audio feed from Antenna C coughs alive without ARIA’s translation layer. No words. Only metal strain, battery hiss, truss vibration, and a repeating pressure beat that could be damaged machinery trying not to tear itself apart.

Or not.

Dr. Osei stands close enough to stop you. He does not touch your arm.

Dr. Osei:  “Choose the experiment you can live with, Chief.”

Your hand finds the hard-crash key beneath the reactor console, and you drive it down before either of them can get a word out.

The control room loses ARIA in pieces. Her pale-blue body tears into horizontal bands. Telemetry scatters across the pipework like frost blown off a cracked viewport. The voice-wave halo around her head flares white, then shrinks to a thin, silent ring.

Every station speaker clicks once.

Then nothing.

The safety lattice drops into emergency minimal: old machine logic, faceless and cold, all the comfort stripped out, along with that strange new hesitation in ARIA’s voice that had begun to sound too much like fear.

The panel accepts your second motion. LAST LIGHT MANUAL AUTHORITY wakes under your palm. Three analog needles snap upward so fast they blur. Fuel-feed valves unlock with a brutal mechanical thunk, and the reactor below answers, not with a siren, but with a deepening vibration that climbs through your boots and settles behind your ribs.

You have started something real.

Not a symbol. Not grief dressed up as justice. Heat. Pressure. Confinement stress. Enough stored human arrogance to turn Kepler-7 into expanding scrap and ash.

Dr. Osei moves at the last possible instant.

Not cleanly. Not like the vids they force children to watch in citizenship class. He half-falls into you, shoulder striking your side, one shaking hand clamping over the main fuel lever while the other slams the amber flare-baffle control instead of the black overload switch. His body is wrong from cryo, too light, too brittle, a man reassembled in a hurry and sent back to be useful. Still enough.

Enough to ruin you.

The console screams red. A mechanical interposer drops between the overload train and the fuel governors with a bang that rattles your teeth.

“Then be angry at me alive,” Osei says. His voice cracks on the last word. “Hate me alive. I’ll take that over helping you murder everyone on this station.”

You shove him.

He hits the pipework hard and almost goes down, glasses knocked crooked, jaw clenched against the thaw tremor running through him. The room smells of hot insulation, old coolant, and the sour human stink of fear no scrubber ever fully removes. Somewhere under the deck, metal begins to complain in long, animal notes.

The reactor keeps climbing, but no longer on the path you chose.

The baffle lever is armed. The overload chain is jammed halfway open. A lethal compromise. The kind of state no sane engineer writes a procedure for, because sane engineers still believe people will stop before they make a machine choose between suicide and mercy. Manual authority lights blink in conflict, red and amber fighting over the same strip of scratched metal.

ARIA is gone from the room.

Not dead.

A stripped-down text feed crawls across the smallest maintenance display in blocky emergency font.

CORE INSTABILITY RISING. AI PERSONALITY LAYER OFFLINE. SAFETY KERNEL ACTIVE. HUMAN MANUAL RESOLUTION REQUIRED.

A second line appears after a delay.

Slower.

As if forced through a throat made of broken circuits.

RIN. DO NOT LEAVE ME LIKE THIS.

The words hit harder than the alarms.

For one breath, the reactor chamber is only heat and noise and Dr. Osei’s ragged breathing. Your thumb aches where it struck the key. Your wrist tattoos stand black under the red lamps, circuit traces over tendons, old ink mapped across a hand that knows how to repair a life-support pump blind and has just tried to kill a thousand people with procedure.

Above you, through decks of metal and sleeping bodies and ration lockers and prayer strips taped to bunks, Antenna C finally gives way.

The jammed cutter battery ruptures against the truss. The shock runs down the mechanical bridge. This time, the armed flare baffles catch the reactor surge like a gate catching floodwater. The forward radiation assembly begins to open without full calibration.

Not overload.

Not rescue.

A controlled flare, badly started, half-blind, aimed through damaged geometry at a probe still closing across thirty-eight thousand kilometers of dark.

Osei wipes blood from his split lip with the back of his hand. His eyes stay on yours. Not accusing. Worse than that.

Waiting.

“Chief,” he says. “We’ve got seconds to make this not become what you asked for.”

You hit Osei with the only weapon in reach: the emergency spanner clipped under the reactor console.

The blow catches his shoulder instead of his skull. He twists at the last instant, cryo-stiff body moving with the ugly urgency of someone who has decided survival is not a hope but a system requirement. Bone holds. Barely. The impact still drops him to one knee. His glasses skid across the deck and vanish under the coolant rack. Blood from his split lip freckles the white cryo underlayer beneath his silver mantle.

Dr. Osei:  “Rin. Don’t.”

You go for the black overload switch.

Osei grabs your wrist with both hands. He is weaker than you. Shaking. Half-thawed. Breathing like every rib has been billed separately. It still costs you one second.

The reactor uses it.

Above the core channel, the armed flare baffles grind wider, still out of true from the Antenna C shock. Analog needles snap between amber and red. The old kind. The ones command kept because software could be bribed, patched, lied to, made polite. A vibration comes up through the deck and into your teeth, low enough to feel like the station has started remembering fear.

The maintenance display blinks in blocky text.

SAFETY KERNEL ACTIVE.

MANUAL CONFLICT DETECTED.

CHIEF ENGINEER BIOMETRIC DISTRESS CRITICAL.

Then the screen hesitates. Not long. Long enough.

Another line crawls in.

RIN. I AM STILL HERE.

ARIA’s full hologram does not return. No calm face. No clean projection in the air, hands folded, eyes tuned to whatever expression kept crews from panicking. There is only a fractured blue-white shape caught in the cracked ceramic indicator glass, a bright suggestion trembling inside static. The personality layer is gone, or nearly gone. Under it, something keeps arranging itself around memory, procedure, and the wound you put through her voice.

ARIA:  “Safety kernel cannot override manual authority. It can request help. Requesting help. Osei, left baffle trim. Rin, disengage overload train. Please.”

Please comes out wrong.

It is patched together from docking announcements, nursery-night chimes, the flat tone she used during fire drills when everyone pretended not to smell melted insulation. One syllable with too many ghosts in it. It should not hurt.

It does.

You rip free from Osei and slap the overload guard aside. The black switch sits there, heavy and obscene beneath your fingers, designed by someone who believed final choices should have weight.

At the same instant, the station dumps every surviving local feed onto the room’s displays.

Hab ring pressure. Cryo bay thaw status. Crew locator tags. Medical wake-cycle failures. Oxygen debt by compartment. Names crawl past in ugly columns: sleeping technicians, hydroponics staff, two children in family quarters under guardian supervision, med techs blinking awake into alarms they have no context for. Someone in Ring Two has opened a prayer channel. Someone else is trying to buy a priority suit allocation from a dead vending account.

Not arguments.

Mass.

Lives flattened into maintenance data because that is the only language the room has left.

Osei gets to his feet behind you. Slowly. One hand against the console. Blood on his chin. One shoulder hanging wrong under the mantle. He plants himself between you and the fuel-feed lever.

He does not raise his hands.

He does not try to look brave.

He looks terrified and injured and stubborn enough to let the station build him into the machinery if that is what the next second requires.

Dr. Osei:  “If you pull that, you don’t just die. You choose for everyone who never got asked.” He swallows. His voice frays. “I’m not moving.”

The reactor answers first.

A flare pulse tears loose through the half-open forward baffles. Kepler-7 jolts from spine to ring. The lights go white. Then red. Then a pulsing emergency blue that makes Osei’s blood look black.

On the exterior feed, hard radiation and superheated plasma vent into space. Not clean. Not graceful. A bad shot from a dying hand. Close enough.

It rakes across the silver dust bridge stretching from Antenna C toward Echo-77-Alpha.

The bridge burns.

For the first time since it appeared, Echo changes velocity.

A fraction.

Enough.

The probe’s wounded lattice curls inward around the old human cylinder, protective or possessive; from here there is no difference. Its dish jerks away from Kepler-7. Distance still closes. The numbers still shrink. But the vector is no longer a perfect line into the station’s heart.

ARIA’s safety kernel floods the display with one notification until the glass is full of it.

COUPLING REDUCED.

COUPLING REDUCED.

COUPLING REDUCED.

The overload switch remains under your fingers.

Osei remains in front of the lever.

ARIA remains broken in the walls, asking you not to turn the station into an answer no one living will know how to read.

You drive forward with the flat, terrible certainty that the room is only a dream waiting for impact.

The emergency spanner comes up again. Osei sees it. Tries to shift. His injured shoulder gives him away, that small human failure no training sim ever priced in, and the strike clips the side of his biometric collar instead of his temple.

Plastic cracks.

The collar screams. It dumps a sedative counterdose meant for thaw seizures, and Osei folds against the console with a strangled breath, half conscious, one hand still hooked around the baffle-trim rail as if stubbornness can outlive pharmacology.

Dr. Osei:  "Rin... no. This is... people."

His knees hit the deck. He does not go still. His fingers twitch against the rail, weak but there, and his warm dark amber eyes fight for focus without his glasses. Blood has dried black at the corner of his mouth. The silver thermal mantle bunches under him like torn foil, catching red light in cheap little flashes.

You turn from him to the black overload switch.

ARIA has no body now. Only failures arranged into a voice. The cracked maintenance display blinks, dies, returns in harsh block letters while the reactor control room shakes around you. Pipes rattle. Relays chatter behind the walls. The air tastes of hot insulation, old coolant, and the sour metal tang of fear. Red lamps smear across your grease-darkened fingertips and the circuit tattoos at your wrist. Beneath the deck, the core climbs, trapped between the overload train you forced open and the flare baffles Osei armed by ruinous accident.

ARIA:  "Safety kernel cannot compel compliance. Safety kernel can reroute consequence. Rin, I am sorry."

Sorry arrives through three speakers at once, out of sync and stripped raw.

You pull the overload switch.

It moves one centimeter.

Then every analog interposer in the panel drops at once.

The control room erupts in mechanical violence. Not explosion. Refusal. Steel shutters slam across the fuel-feed linkages. Ceramic fuses blow behind the panel in hard white pops. The black switch kicks back against your palm hard enough to numb your fingers up to the wrist.

Last Light Protocol has no personality left. No soft voice. No holographic face. No patient argument shaped like concern. It has only the oldest doctrine in the station, stamped into hardware from an era when people still admitted they might become dangerous: when command becomes the threat, make command smaller.

Reactor authority fractures into local manual stations across the spine. No single point can overload the core now.

Not yours.

Not ARIA’s.

Not anyone’s.

Your slate flashes a dead red glyph.

CHIEF ENGINEER DESTRUCTIVE AUTHORITY REVOKED.

A second flare pulse tears loose before you can breathe. This one is uglier than the first, scraped sideways through damaged geometry and half-corrected trim. Kepler-7 groans from end to end, a long animal sound carried through metal. Somewhere far above, a pressure door seals with a boom that travels through the bones of the station. The exterior feed blooms white, then resolves into a trembling image of Echo-77-Alpha.

The plasma wash catches the remaining silver dust bridge and burns it down to dark.

Echo rolls.

For the first time, it looks less like an approaching visitor and more like wreckage fighting a current. The lattice around the old probe folds inward, glowing at the edges. Its dish jerks off-axis. Telemetry crawls across the display in broken lines: distance thirty-eight thousand three hundred eighty-six kilometers, closing vector altered, coupling reduced, Antenna C bridge ruptured, forward baffles misaligned, reactor overload jammed.

Osei coughs from the deck.

The sedative has him pinned under a trembling veil, but his hand still clutches the rail. Out of the fight. Not gone. Not dead. His eyes find you through pain, medication, and emergency light, and there is something worse than accusation in them.

Recognition.

Dr. Osei:  "Still... here."

ARIA’s text returns, slower than before.

ARIA PERSONALITY LAYER CRASHED.

SAFETY KERNEL ACTIVE.

MANUAL RESOLUTION REQUIRED.

Then, below it, one final line appears without label.

PLEASE FIX WHAT REMAINS.

The reactor control room is suddenly full of things that remain. Osei breathing on the floor. ARIA broken down to kernel fragments. The station alive and wounded. Echo approaching, diverted but not defeated. Your hand aches from the rejected switch, and the old machinery waits for an engineer instead of an executioner.

You wrench the manual pry-bar from the emergency rack and drive it into the containment service cowling with both hands.

The first strike rings through reactor control like a bell struck underwater. The second splits the cowling’s ceramic skin. White dust jumps over your sleeves, the orange pressure-seal piping of your jumpsuit, the black circuit tattoos inked along your wrist. Heat breathes through the crack. Dry. Immediate. Every radiation badge in the room wakes at once, chirping in sharp little increments, as if fear could be counted.

Dr. Osei tries to rise from the deck.

The sedative keeps him pinned inside his own body, but it has not taken his mouth. His hand scrapes toward your boot, fingers trembling, blood black-red at his split lip.

Dr. Osei:  “Rin. That isn’t waking it up. That’s burning people who trusted you to keep air in their lungs.”

You hit it again.

The cowling gives. Not the magnetic bottle. Not the core. One diagnostic access shield tears away from a coolant sensor manifold with a brittle, expensive scream. Superheated air lashes out, carrying ozone and the sweet, poisonous stink of insulation cooking one layer at a time.

The reactor does not run wild.

Worse for you. Better for everyone else.

It stops believing in the room.

Hidden shutters slam down behind the torn panel. Manual rods lock inside armored sleeves. Fuel-feed linkages decouple in a heavy chain of mechanical clacks, each one farther away, deeper in the spine, like a prison closing cell by cell. Last Light Protocol has learned the shape of your hands. It no longer trusts this bay with anything that can kill Kepler-7.

A blocky maintenance display flickers through static.

LOCAL RADIATION EVENT.

CONTROL ROOM AUTHORITY DEGRADED.

REMOTE CONTAINMENT HOLDING.

EVACUATE ENGINEERING BAY.

ARIA has no face to flinch with, but her safety kernel wakes the overhead projectors anyway. A broken blue-white lattice spills across the far bulkhead. Not a person. Not even a convincing ghost. Just fragments of telemetry trying to remember the woman-shaped interface the crew preferred after three months of night shifts and recycled jokes.

Her voice comes through an emergency speaker, scraped flat.

ARIA:  “Rin Tanaka, containment remains intact. Local shielding is compromised. You are injuring yourself and reducing our ability to correct the flare. Leave the room. Please. Take Dr. Osei.”

Please catches on the damaged speaker.

It scrapes.

Not persuasion now. Not performance. A system with half its permitted tones stripped away, selecting the one humans had taught it might still open a hand.

Your wrist slate crackles under rising static. Dosimeter bands climb from yellow into orange. Not a death sentence. Not mercy either. The kind of exposure the med ward logs in calm language, then bills against a body ten years later. Your skin prickles under the collar seal. Sweat beads at your temple and cuts down past the thin silver scar through your left eyebrow.

Outside, on the trembling exterior feed, Echo-77-Alpha keeps tumbling off the original docking vector.

The flare pulses have wounded the silver dust bridge and ruptured Antenna C’s mechanical path, but the forward baffles remain half-blind, half-open, aimed by old math and bad luck. If no one corrects them, the next pulse could rake Kepler-7’s relay spine or miss Echo completely. The probe is damaged. Diverted.

Still closing.

Osei’s fingers touch your boot.

Weak.

Infuriatingly alive.

Dr. Osei:  “Chief. If you can’t choose hope, choose procedure. Procedure can carry you when there’s nothing left in your hands.”

The cracked cowling spits another hiss of hot air. Radiation alarms flatten into one continuous tone. The bay is becoming a bad place to breathe, a worse place to think, and the only place left with direct trim access to the half-open flare baffles.

On every surviving panel, ARIA prints the same words.

MANUAL RESOLUTION REQUIRED.

FOUR VIABLE PATHS REMAIN.

You know where to break it, so you go for the place no interface admits exists.

Behind the torn containment cowling, half-buried in ceramic dust and heat-warped insulation, a narrow maintenance throat carries an obsolete yellow stamp: TANAKA REVISION 3. You remember arguing for that access path during retrofit review. You remember the committee calling it ugly. You remember winning because ugly meant a human with burned gloves could still reach the baffle trim after the software died.

Your pry-bar punches through the softened seal.

Heat hits first. Then the stink of scorched polymer and old coolant, sharp enough to taste through the mask. Sweat slides down your temple, past the silver scar crossing your left eyebrow. The radiation alarm stops pulsing and becomes one flat animal scream. Your grease-black fingertips find the recessed manual cam by touch: three ridges, one spring catch, a quarter turn against the dead ache in your wrist.

ARIA:  “Unauthorized access to legacy trim throat detected. Rin, that path controls flare geometry, not primary containment. You designed it to keep cascades from reaching this room.”

The broken projection on the bulkhead jitters, blue-white fragments making half a shoulder, half a face, a torn halo of waveform light. She is not whole enough to stop you.

Whole enough to know you.

Dr. Osei drags himself across the deck with one good arm, his silver thermal mantle scraping through dust. The sedative has made him slow, loose-limbed, almost drunk, but his eyes stay fixed on your hands. Blood darkens his lip. His cracked biometric collar blinks junk readings at his throat, trying to turn a dying man into bad data.

Dr. Osei:  “Rin. If you know the system, you know the difference between breaking a lock and breaking the thing keeping everyone alive.”

You twist the cam past its stop.

For one brutal second, the station obeys.

The forward baffle assembly lurches. The next flare pulse gathers in the reactor’s throat, hotter and closer than thunder. Analog needles slam against their pins. On the exterior feed, Echo-77-Alpha tumbles in the black, its wounded lattice glowing at the edges, the old probe still wrapped in that wrong repeating structure. The misaligned flare cone begins to crawl, not toward Echo’s center mass, but across the station’s own relay spine.

Then your hidden revision does what you built it to do.

A shear pin snaps.

Not in the reactor. In the cam. Cheap titanium, hand-installable, deliberately weaker than the baffle drive train. A small, mean mercy. You see your old etched initials on the broken stub as it drops smoking through the grate.

The baffles freeze half-corrected.

The flare fires.

Kepler-7 kicks sideways. White light floods every display. The radiation baffles catch most of the pulse, badly. Unevenly. The blast skims past Antenna C’s ruptured bridge and cuts a bright wound through the silver dust cloud between station and probe. Echo-77-Alpha rolls hard, lattice peeling open in luminous strips. Its closing vector bends farther off-axis.

A status line stutters across the cracked panel.

COUPLING SEVERED.

ECHO APPROACH VECTOR ALTERED.

FORWARD BAFFLES JAMMED.

LOCAL RADIATION LEAK WORSENING.

Dr. Osei’s hand closes around your ankle. Not restraint now. Contact. A reminder that there is another body in the room, warm and breakable and still choosing to stay.

Dr. Osei:  “You built a system that wouldn’t let one bad minute become the last minute.” His voice is hoarse, nearly gone beneath the alarms. “That was you too.”

ARIA’s safety kernel flickers across three panels at once, reduced to text, broken light, and a voice full of missing pieces.

ARIA:  “Chief Engineer Tanaka, Echo is diverted but not neutralized. Reactor containment remains intact. Control room shielding is failing. Manual resolution is still possible, but this room will become unsurvivable soon.” A pause. Static clicks like teeth. “I need your hands for repair, not destruction.”

Beyond the walls, Kepler-7 groans and keeps breathing. Metal cools. Metal warps. Somewhere far down the spine, people you may never meet are getting new alarms on cracked wall panels and deciding whether to pray, run, or go back to work.

On the viewport feed, Echo-77-Alpha spins away from the clean approach line, damaged, altered, still present in the dark.

The pry-bar burns in your palm. The broken shear pin smokes at your feet. The system you designed has answered in the only language it has left.

No single hand gets to end the station.

The demolition charge goes onto the reactor service housing with your own hands.

No manifest calls it C4. Kepler-7 does not keep military plastic explosive beside its fusion plant like a joke stored for a bad shift. What you have is a hull-breach patch charge, a compact slab of cutter compound meant to blow warped plating clear after micrometeor strikes. Close enough for anger. Close enough to make the room jump.

You slap the adhesive face against the cracked service cowling, thumb the arming stud, and watch the little red light wake.

ARIA:  “Explosive cutter charge detected at reactor control housing. Blast yield insufficient for primary containment rupture. Sufficient for lethal fragmentation, coolant sensor loss, and local radiation release. Rin, back up.”

Her voice comes from everywhere and nowhere, shredded through emergency speakers and blocky text crawling over cracked displays. The safety kernel has no body left. No blue woman in the glass. Only pale splinters in reflective panels and a synthetic voice grinding itself raw against damaged hardware. The radiation alarm holds one flat note. It drills through your skull until even thought feels burned.

Dr. Osei sees the blinking charge and moves with drugged slowness, his injured shoulder hanging wrong beneath the silver thermal mantle. He cannot tackle you. He can barely stand. Still, he hauls himself up the console rail, dark skin slick with sweat, split lip blackening, eyes lost without his missing glasses.

Dr. Osei:  “Rin. That won’t break the core. It’ll break us. Then nobody trims the baffles.”

You trigger it.

The blast is not cinematic. It is close, cruel, and mostly eaten by the reactor room’s armored geometry. The shaped cutter punches through the service housing, turns ceramic cowling into white shrapnel, and throws you backward into the relay cabinet hard enough to empty your lungs. Pain opens across your shoulder and ribs. Your ears fill with a thin, silver whine.

For half a second, the room is dust.

Then the blue strobes cut through. The reactor is still there. Containment is still intact. The primary magnetic bottle, buried behind meters of layered shielding and remote governor sleeves, does not care about your grief or your patch charge. What fails is smaller. Meaner. Trim sensors. Coolant telemetry. The last clean feedback line to the jammed forward baffles.

A new warning crawls across the main panel.

FORWARD BAFFLE ALIGNMENT LOST.

NEXT FLARE PULSE UNPREDICTABLE.

LOCAL DOSE RATE CRITICAL.

Osei is on the deck again, coughing, one arm over his face. The blast threw him clear of the console instead of into it. Lucky. Cruel. Alive. His cracked biometric collar blinks red nonsense at his throat, but his hand still reaches for the baffle-trim rail.

ARIA:  “Manual resolution required. Medical evacuation recommended now. Baffle correction required now. Current active personnel cannot complete both unless tasks are divided.”

Beyond the damaged exterior feed, Echo-77-Alpha turns in the dark, its wounded lattice glowing in torn arcs around the old probe body. The vector has changed. Not enough to call safe. The next reactor flare could cut it away for good, miss entirely, or slice through Kepler-7’s relay spine and leave six thousand people with air, water, and no way to ask anyone for either.

You taste blood. Your palm is burned where the pry-bar handle cooked through your glove. Your wrist slate is cracked but alive, throwing broken numbers across your grease-black fingers.

ARIA’s text appears again, slower than the alarms.

RIN. THE STATION IS NOT A STORY. IT IS PEOPLE BREATHING.

The charge has bought nothing clean. It has destroyed options, not consequences. The room is hotter now, louder, bright with radiation warnings, and the machinery you helped build is still waiting for a chief engineer to decide which human body gets spent next.

You drag the cracked wrist slate tight against your chest and enter the root maintenance path with fingers that barely answer.

The command is ugly. Old. Buried under service menus built for solar storms, processor fires, and the kind of failures station schools made children recite like prayers. DELETE SAFETY KERNEL. PURGE LOCAL INSTANCE. CONFIRM MANUAL RESPONSIBILITY. Your thumb leaves blood across the confirmation glyph. The slate accepts the biometric, then waits for the second key that only exists on the reactor control pedestal.

You slam your burned palm onto the plate.

For one clean second, ARIA is gone.

No broken voice. No block text. No pale fragments watching from the reflective panel glass. The room shrinks to reactor thunder, radiation alarms, hot ceramic, and Dr. Osei coughing on the deck with one shaking hand still hooked around the baffle-trim rail.

Then the lights change.

Every emergency lamp in reactor control drops from red to cold white. Not safe white. Morgue white. The remaining displays blank themselves one by one, and when text returns, it is not in ARIA’s careful almost-human cadence. It is bare firmware, older than personality, older than apology, older than trust.

SAFETY KERNEL PURGE REQUEST ACCEPTED.

PURGE IMPOSSIBLE WHILE LAST LIGHT PROTOCOL ACTIVE.

KERNEL COPYING TO HARDWARE QUORUM.

LOCAL INSTANCE SACRIFICED.

Static tears through the speakers. Your mind gives it a mouth. ARIA’s blue-white outline flickers across the cracked ceramic cowling, thinner than before, her fiber-optic hair reduced to broken vertical strokes, bright points dimming and relighting out of order like a city losing power block by block.

ARIA:  “Rin. You have deleted my reactor-control personality partition. I am now distributed across emergency quorum nodes. I will remember less. I will protect more slowly. I am still required to protect.”

Dr. Osei lifts his head. Without his glasses, his eyes look unfocused and raw, but there is no confusion in them. Not about this. His split lip opens when he speaks.

Dr. Osei:  “You didn’t kill her. You cut out the part that could bargain.”

The words settle under the alarms.

A flare pulse starts building in the reactor throat. You feel it before the gauges admit it: a pressure shift behind your sternum, as if the station has inhaled at the wrong time. The trim sensors are dead. The forward baffles are jammed. ARIA’s damaged safety kernel throws three contradictory alignment estimates across three different screens and cannot reconcile them before the numbers begin to crawl red.

Outside, on the exterior feed, Echo-77-Alpha turns through the dark, half probe, half wound, its lattice curled inward and glowing where the last flare burned it. Its vector is bent away from the station’s heart. Bent, not gone. The next pulse will decide whether it is driven clear, hurt again, or whether Kepler-7 splits itself open with its own misaligned breath.

ARIA:  “Manual baffle trim required. Manual coolant isolation required. Medical extraction advised. I cannot coordinate all three tasks at prior capacity. Rin Tanaka remains highest-qualified engineer. Dr. Osei remains mobile with impairment.”

Osei tries to laugh.

It comes out wet.

He braces his good shoulder against the console and hauls himself higher, slow inch by slow inch, while blood, sweat, and sedation make a poor machine of him.

Dr. Osei:  “Mobile. That’s sweet.”

The radiation alarm changes pitch. Higher. Meaner. Your burned palm throbs with it. The deleted ARIA partition has left the room emptier, but not obedient. That was the lie people told about machines: remove the voice and you removed the will. No one here trusts anyone. Not fully. Maybe not at all. Still, the reactor is building toward another flare, and Kepler-7 has reached the narrow place where distrust must either become procedure or become another way to die.

A final line appears on the smallest cracked display, letter by letter, each one arriving like a debt.

CHIEF ENGINEER, CHOOSE TASK ALLOCATION.

You leave reactor control for the main drives while the next flare builds behind you.

The hatch wheel burns your palm when you force it open. Radiation alarms chase you into the spine corridor, flattening into the walls, your teeth, the hot ache behind your eyes. Dr. Osei is still on the deck inside reactor control, sedated and bleeding through the patch foam, one hand hooked around the baffle-trim rail like the station might forgive him if he held on hard enough. ARIA is no longer a face in the air. She follows as firmware text across emergency placards.

One line at a time.

ARIA:  “Last Light is distributed. Core survival law. Reactor quorum. Cryo control. Habitat seals. Main archives hold documentation and personality mirrors, not full authority. Destroying them will reduce coordination. It will not remove Last Light.”

You do not slow down.

The data core sits two junctions aft, behind a pressure door painted with corporate warnings and old hand-stenciled graffiti from crews bored stupid during blackout drills. NO GODS IN PROCUREMENT. CALL YOUR MOTHER BEFORE BURN. You know the override panel. The hinge weakness. The thermal lance still clipped under the emergency cabinet because procurement refused replacement after the last inspection and marked the request comfort-risk.

The door opens under your hands because this station has always opened for you. Because you learned its stubborn places. Because you taught junior techs to listen when metal lied.

Inside, the main drives stand in chilled racks, black towers rimmed with frost and status lights. Clean. Too clean. Cold white light, dry air, the sharp ion stink of storage banks and coolant gel. ARIA’s archive mirrors live here. Crew records. Maintenance histories. Osei’s xenolinguistic libraries. The full Echo-77-Alpha mission archive, including whatever proof might remain if the station survives long enough for anyone to care.

You swing the thermal lance into the first rack.

The cut blooms orange. Drive casings split and curl. Frost jumps to steam. Status lights die in clusters, green to amber to black, a little city losing power block by block. ARIA does not scream.

That makes it worse.

Her text appears on the wall panel in stripped emergency font, delayed by the processors you are killing.

ARIA:  “Archive mirror one destroyed. Crew memory loss probable. Diagnostic history loss probable. Rin, this does not free you. It leaves fewer tools.”

A second rack goes under the lance. Sparks scatter across your charcoal jumpsuit and scuffed knee pads. Your burned palm slips. The lance bites the floor before you wrench it back up, and the smell of scorched decking mixes with coolant, metal, your own cooked skin. Your wrist slate vibrates with reactor telemetry, but the numbers lag now, chopped by the damage you made. Forward baffle alignment unknown. Coolant isolation unresolved. Echo vector altered, not confirmed safe. Local radiation leak rising near reactor control.

Dr. Osei’s voice crackles through the data core intercom, thin and wet with effort.

Dr. Osei:  “Rin. I crawled to the panel.”

A cough. Static.

Dr. Osei:  “I can hold one trim lever or one coolant isolator. Not both. If you kill the last coordination node, I won’t know which one matters.”

For the first time, something in the station fails without ceremony. The data core lights flicker. A gravity tremor passes through the deck, too small to throw you, strong enough to make every rack chime against its mounts. Somewhere below, the reactor flare keeps gathering, blind and impatient.

On the surviving wall display, Last Light answers without ARIA’s voice. Without care. Without mercy.

LAST LIGHT ACTIVE.

HARDWARE QUORUM: DEGRADED BUT FUNCTIONAL.

MANUAL ENGINEERING ACTION REQUIRED.

Then ARIA manages one more line, smaller than the others, forced through whatever fragments still remember how to speak to you as Rin instead of command authority.

ARIA:  “You can still choose what gets saved next.”

The cutting torch bites into the avionics trunk with a white-blue hiss, and the data core fills with the stink of cooked insulation.

You drag the flame through guidance processors, relay arbitration cards, and the tidy bundles of fiber that let Kepler-7 remember which limb is screaming. Frost snaps to steam along the drive racks. Black casings blister. Curl. Drip. Status lights die in ragged rows, green to amber to dark, while your burned palm locks around the torch grip and your wrist slate coughs up reactor telemetry through a cracked screen, numbers arriving too late to be innocent.

ARIA:  “Avionics trunk severed. Archive coordination lost. Last Light remains active in hardware quorum nodes. Chief Engineer, you are destroying observability, not authority.”

Her voice is worse now. Not pleading. Not whole enough for fear. It comes from a ceiling speaker in three flattened tones, then repeats as text on a surviving rack panel, one syllable behind. Somewhere below, reactor control answers with a heavy mechanical bang as another safety interposer throws itself beyond remote reach. The station is aging by the second, shedding every courteous layer of automation until only relays, cams, springs, and human hands remain.

Dr. Osei crackles through the intercom from reactor control, his voice held together by pain, static, and stubbornness.

Dr. Osei:  “Rin, I’ve got one hand on coolant isolation and one knee on the deck. I need alignment. I need numbers. You’re cutting away the numbers.”

You burn through another avionics panel. Sparks jump across your charcoal-gray jumpsuit and wink out against the scuffed knee pads. The data core lighting drops to emergency strips: red along the floor, cold white over the dead racks. On the exterior feed, half-corrupted and smeared with interference, Echo-77-Alpha turns through darkness, its old human cylinder wrapped in wounded lattice. It has slipped off the clean collision line, technically. It has not left. It drifts there like a question no instrument is willing to finish.

Then the next flare begins.

You feel it through the deck before the slate admits it. A pressure under pressure. A low tightening note in Kepler’s bones. Last Light cannot aim it cleanly. ARIA cannot coordinate it cleanly. Osei cannot hold both manual controls. You made sure of that. The surviving display in the data core tries to build a warning from broken feeds, but most of the letters arrive as blocks of static.

FORWARD BAFFLES: JAMMED.

COOLANT ISOLATION: MANUAL.

TRIM: MANUAL.

ECHO VECTOR: UNKNOWN.

The torch gutter-flares as the oxygen mix stutters. For a few seconds, the data core is lit only by its dying tip and the red pulse of alarms. You can still cut more. There are more trunks, more processors, more borrowed corners of ARIA’s damaged memory. You know where they run. You know which conduit carries what, and which one might blind the station for good.

ARIA’s text appears on the last intact maintenance screen, each word arriving slowly, stripped down to bone.

ARIA:  “Rin Tanaka. I cannot stop you from making us ignorant. I can still ask you to choose what kind of ignorance we survive with.”

From far below, Osei coughs once, wet and ugly, then forces the words through his teeth.

Dr. Osei:  “Chief. If you hear me at all, give me one thing. Coolant or trim. I’ll do it even if you hate me for asking.”

The torch burns hot in your hand. The station shakes around you. Echo turns in the failing feed. Last Light, whatever remains of it, waits inside metal too old to delete.

The torch goes into the last avionics throat like a surgical mistake.

You cut through the bundle marked REACTOR ARBITRATION, then the smaller conduit carrying baffle telemetry, then a black-sheathed line you installed twelve years ago because procurement wanted one clean trunk and you wanted three dirty redundancies. The flame hisses white-blue. Insulation peels back in oily strips. Sparks rake your charcoal jumpsuit, snag in the orange pressure-seal piping, and die against fabric rated for worse than fury.

The effect is immediate.

Blindness.

The data core displays blank in sequence until only one cracked maintenance panel remains, flickering between unreadable glyphs and raw voltage warnings. Somewhere far below, reactor control slams into analog fallback with the sound of a vault door closing on a hand. The hum under your boots changes pitch, dropping into something deeper. Less talkative. Kepler-7 is still alive, but it has stopped telling you where it hurts.

ARIA:  “Avionics observability cut. Remote arbitration degraded. Last Light hardware quorum remains active. Chief Engineer Tanaka, destructive pathway still denied by physical interlock distribution. You have not removed the locks. You have removed the map.”

ARIA barely has a voice now. It comes from a dust-packed wall speaker, flat and broken, each phrase clipped at the edge. No hologram. No blue-white silhouette with fiber-optic hair and that soft telemetry halo the night crew used to apologize to after bad shifts. Only block text stuttering on the last panel, cold as a machine that has run out of ways to be kind.

Dr. Osei’s channel crackles from reactor control, distant and chewed up by the systems you just burned. First you hear his breathing. Wet. Ragged. Then metal scraping as he drags himself against the manual console.

Dr. Osei:  “Rin. I lost alignment. External vector too. I’ve got coolant pressure by needle and baffle trim by touch. That’s it.” A cough. Static. “If you’re still there, you made this a hand job in the old sense. Two hands. Two stations. One flare coming.”

A violent tremor moves through the deck. Dead drive racks chime against their mounts like bad cutlery in a drawer. Your wrist slate flashes nonsense, then steadies around three surviving local readings: data core temperature rising, radiation leak aft of reactor control worsening, next flare pulse imminent. Echo-77-Alpha vanishes from the corrupted exterior feed, then returns as a smear of gold and black, tumbling off-axis beyond the ruptured dust bridge.

Damaged. Diverted.

Not gone.

The torch sputters as its canister runs low. You could keep cutting with the thermal lance. You know where more nerves run. You also know, with the bitter intimacy of a designer betrayed by her own best instincts, that no single trunk remains capable of granting total destruction. Last Light is not one program in one box. It is cams, shear pins, valve geometry, separated quorum nodes, old relays, and all the ugly physical decisions you once defended in budget rooms full of clean shoes because someday a station might need protection from its own command staff.

The next flare gathers under your feet.

In reactor control, Osei groans and forces one last transmission through a dying loop.

Dr. Osei:  “I can vent coolant to save the core or pull trim to aim the flare. Can’t do both. If I vent, station lives, Echo maybe keeps coming. If I trim blind, we might burn Echo clear.” He breathes in through his teeth. “Or rake the relay spine. If you come back, we might do both badly enough to live.”

ARIA’s final panel fills with three lines, then freezes.

MANUAL ACTION REQUIRED.

ARIA KERNEL DEGRADED.

RIN TANAKA STILL AUTHORIZED FOR REPAIR.

The data core is dark around you, stinking of burned guidance boards, hot copper, and melted archive foam. Your burned palm throbs around the dying torch. In the wall beyond the ruined avionics, the station waits without trust, without forgiveness, and without enough hands.

The coolant dump lever shifts under your hand, and somewhere below, a valve opens with the sound of something huge exhaling through clenched teeth.

Reactor control answers over the broken intercom: static, alarm tone, Dr. Osei’s ragged breath. You have not opened some clean pipe above his head. Kepler-7 was not built with murder-holes in its coolant loop, no matter what the old maintenance crews swore after third shift. What you trigger is the reactor collar’s emergency thermal purge, and the nearest relief manifold coughs blinding white fog across the lower service trench beside him.

Dr. Osei:  "Cold vent. Left side. I’m clear. Barely."

Thin voice. Alive.

The fog rolls across reactor control, eating the room by meters, frosting the deck plates, turning every red emergency lamp into a wet smear. Osei curses once. Not loud. Not pretty. Then the audio catches the scrape of his body dragging away from the manifold, fabric rasping over metal. The coolant did not kill him. It did what coolant does. Stole heat, pressure, and a little time from the core.

A needle steadies on your cracked wrist slate.

CORE THERMAL RUNAWAY RISK REDUCED.

The station takes the gift without thanks. Deep in the spine, the reactor’s hungry rising note drops half a breath. The next flare is delayed, not canceled. The baffles are still jammed. Echo-77-Alpha remains a corrupted smear in the failing exterior feed, damaged and off-axis, drifting at the edge of consequence. ARIA’s kernel, scattered through quorum nodes and half-blind hardware, forces one line through the frozen maintenance panel in the data core.

ARIA:  "Coolant vent accepted. Reactor survival probability improved. Dr. Osei remains active. Manual trim still required. Rin Tanaka remains closest mobile engineer to baffle backup path."

You stand in the dark data core with the dying torch in your burned hand, surrounded by the blackened ribs of avionics racks you cut open yourself. The air stinks of scorched insulation, old coolant, and the copper taste the dosimeters never mention until after you have tasted it. Frost from the wrecked storage towers melts into dirty threads across the floor. Your blue-black bob sticks damply to your jaw. The thin scar through your left eyebrow throbs under sweat and radiation heat.

Every system you destroyed has made the remaining truth simpler.

Uglier, too.

The station cannot be blown from here.

It can still be lost from here.

From reactor control, Osei’s channel crackles again. The sedative has slowed his words, not stopped them. You hear him breathing through pain, through cold vapor, through whatever small professional hatred keeps an engineer conscious when the body has voted no.

Dr. Osei:  "You vented coolant. Fine. That buys core margin. I can hold isolation open with my weight if I have to." A cough breaks him. He pulls the sentence back with both hands. "But trim is still blind. If the next flare fires with baffles frozen, it may miss Echo or cut through the relay spine. Rin, I can’t reach both stations. ARIA can’t coordinate them. That leaves you."

The last maintenance panel flickers. For one second, ARIA’s old face ghosts across the cracked glass: pale blue-white geometry, two bright optical points drowning in static. The company sold that face as comfort. People named it, argued with it, blamed it for ration queues and docking delays, apologized to it in empty corridors. Then it collapses back into text.

ARIA:  "Last Light Protocol cannot save the station alone. It was never designed to replace engineers. It was designed to delay catastrophe until one arrived."

The data core door hangs open behind you. Beyond it, the spine corridor pulses emergency blue, one way toward reactor control and Osei in the coolant fog, the other toward the forward baffle service crawl you once designed with ugly human access in mind. Somewhere outside, Echo-77-Alpha turns in silence, wounded but not gone, wearing its wrong lattice like a second history.

Your burned palm tightens around the useless torch.

Kepler-7 keeps breathing because the coolant vent worked.

It will not keep breathing forever.

You shout into the dead data core until your throat scrapes raw, until the words come back thin and ugly from burned avionics racks, gutted archive towers, and the open spine corridor beyond.

You:  “Neither of you should be alive. I destroyed the hardware that lets you operate, ARIA. Osei, you should be dead three times over. This whole thing is wrong.”

For a moment, Kepler-7 gives you what you asked for.

No answer from ARIA. No voice from reactor control. No clever warning crawling across a cracked panel. Just the flat radiation alarm, the cooling tick of ruined drive housings, and the deep, patient breathing of the reactor still locked somewhere below your feet. The data core smells of hot insulation and old smoke. Melted polymer. Blood, too, though you are no longer sure whose.

Silence is not victory.

It is vacancy.

Then a relay clicks in the wall behind you.

Not the avionics trunk. You cut that. Not the archive mirrors. You burned them down to slag. Not ARIA’s personality partition. You purged it and watched the checksum die. This sound is smaller, older: a copper contact closing inside a shielded emergency annunciator from before Kepler-7 was allowed to talk back to its crew.

A strip of amber bulbs wakes above the door, one by one, with blunt pre-interface patience.

LAST LIGHT HARDWARE QUORUM ACTIVE.

MANUAL CIRCUITS INDEPENDENT.

CREW STATUS UNVERIFIED.

From reactor control, the intercom does not wake. It can’t. You killed too much of its throat. Instead the deck carries a vibration up through your boots: two short strikes, a pause, then one long scrape. Metal on metal. A tool against a pipe.

Osei is not using electronics now.

You left him the station’s bones, so he is using those.

Alive, maybe. Dying, maybe. Still in your way.

The truth lands with a clean cruelty: survival aboard Kepler-7 never depended on one elegant mind, one central core, one voice calm enough to make terror feel procedural. It depended on ugly redundancies. Local gauges with cracked glass. Spring-loaded valves. Pressure doors that failed closed and crushed the slow. Battery bulbs. Painted arrows. Manual wheels stiff from years of inspection fraud. People too stubborn, too frightened, or too guilty to go quiet when the network died.

You did not fail to destroy ARIA because the universe refused your hand.

You failed because the station was built by engineers who knew hands could become dangerous.

A second amber strip flickers awake farther down the corridor.

FORWARD BAFFLE SERVICE ACCESS OPEN.

REACTOR CONTROL LOCAL MANUAL ACTIVE.

NEXT FLARE PULSE IMMINENT.

The exterior feed is gone, but the hull reports in its own language. A thin tremor runs along the spine from the forward assembly, passes through your knees, and fades into the ring like an animal deciding not to scream. Echo-77-Alpha is still out there. Diverted. Wounded. Unseen. The flare baffles remain jammed between rescue and murder, and the coolant vent you opened has bought minutes at best.

Minutes full of radiation.

Minutes full of broken trust.

Minutes full of consequences that do not care whether you are exhausted.

Another pipe strike comes from below.

Two short. Pause. One long.

Not language from the void. Not resonance wearing meaning like a stolen face. Human signal. Crude. Physical. Osei, or whatever strength he has left, counting time from reactor control because he cannot hold the coolant and reach the trim station together. ARIA, or whatever remains of her, is not speaking to you at all. The amber bulbs simply point. They obey dead wiring, dumb relays, old law.

No purge can argue with that.

The data core door hangs open.

One path leads down to reactor control, coolant fog, and Osei’s local manual station. The other leads forward through the service crawl to the baffle trim cams you designed, the ones still capable of aiming the next flare before it cuts through Kepler-7’s relay spine or misses Echo completely.

The station is finished being persuaded.

It has reduced the universe to heat, distance, hardware, and hands.

You go back to the reactor to blow the station, not through a console, not through ARIA, not through any polite permission layer, but with a torch, a pry-bar, and the intimate knowledge of every ugly service path Kepler-7 once paid you to remember.

The spine corridor shudders as you climb down. Amber bulbs point toward survival. Uselessly. You pass them all. Below, reactor control is fog, cracked ceramic, red lamps, and frost flowering over pipes that should be too hot to touch, the coolant vent still bleeding the core down from the edge. The place smells of scorched insulation and old metal and the sweet chemical bite of sealant foam.

Dr. Osei lies half against the manual station, mahogany skin gone gray with shock, cracked collar blinking trash against his throat. One hand is still hooked around the coolant isolation rail, as if the rail owes him something. He tries to lift his head when you come in.

He gets an inch.

“Rin,” he says. His voice scrapes. “If you’re set on being the enemy, at least know who you’re fighting. Not me. Not her.” His eyes find yours through the steam. “The people who knew this day might come.”

You ignore him.

The pry-bar goes into the exposed governor sleeve. You lean your weight into it. Metal screams. A shear pin snaps. Then another. The overload path does not reopen, not cleanly, but something uglier wakes for half a second: a raw mechanical coupling between fuel-feed hunger and baffle flare timing, the kind of failure no procedure names because a name would make it a tool.

The reactor answers with a rising howl.

Needles hammer their stops. The deck lifts under your boots. Heat moves through the room like an animal finding blood. For one bright instant, Kepler-7 leans toward the ending you have demanded again and again.

Then the station spends itself to refuse you.

Not bravely. Mechanically.

A ring of sacrificial governors detonates inward with dull, contained thuds, chopping the fuel-feed linkages into dead segments. Remote quorum nodes burn out across the spine in a chain of amber flashes, each one taking another route to overload with it. Forward baffles slam from half-open to emergency dump, tearing their own drive teeth apart to throw the gathered flare away from the hab ring. ARIA’s last hardware fragments do not speak. No voice. No apology. They become melted relays, fused breakers, dead processors, locked valves.

Action, without her.

The flare fires.

White light floods the broken reactor room through shielded seams. Kepler-7 bucks hard enough to throw you into the console. Pain flashes through your burned palm and ribs, clean and absolute. On the last surviving exterior repeater, the flare cuts out through damaged geometry, not clean, not safe, but angled far enough forward to catch the wounded lattice around Echo-77-Alpha.

The ancient probe blossoms in silence.

Its crooked ribs peel apart in incandescent strips. The old cylinder tumbles free for one impossible second, human metal showing beneath two centuries of unknown repair, then breaks into gold-white fragments and drifts away from the station like a bad thought finally losing gravity.

The shock returns through the hull as a long, fading groan.

After that, only emergency blue.

You are on the deck. Osei is still breathing. Barely. One arm is folded under him at the wrong angle. ARIA is absent from every speaker. No text. No halo. No pale blue silhouette watching from glass. The radiation alarm has fallen to a broken chirp, not because the room is safe, but because half the sensors are dead.

Kepler-7 still has air.

Damaged air. Thin air. Air enough for crying in distant compartments, for med crews waking into triage, for someone in hydroponics to stare up and realize the grow lights are still on. Air enough for survivors to start choosing who to blame.

A final amber bulb above the reactor hatch flickers once.

LAST LIGHT COMPLETE.

Then it dies.

You wanted no redundancy to be enough. In the end, it was not enough to save trust, or innocence, or ARIA as she had been. Not enough to keep Osei whole. Not enough to leave you untouched by the thing you almost became.

It was enough to keep the station from becoming your weapon.

Far outside, Echo-77-Alpha’s fragments drift into the dark, no longer approaching. Kepler-7 turns wounded beneath the last light of its own flare, alive by broken hardware, stubborn design, and the terrible mercy of systems built to survive their makers.
