A Dead Gas Giant Has A Horrifying Secret Hiding In Its Lower Atmosphere

0:00Before we begin, Galactic Horrors is now on Patreon. Get daily stories in one place, with no ads and no interruptions. Link is in the description or search Galactic Horrors on Patreon. Now, let's begin the transmission. 14 more runs. That was the number I carried into the cabin every shift. The number I recalculated against the company's shifting deduction schedule every time I couldn't sleep. 14 runs at the current volume rate, after equipment, surcharge and filter degradation, plus whatever tecton atmospheric decided to call machine misuse this month. A drop in grinder efficiency made it 15. Another clogged mesh made it 16. The numbers changed every day. The debt didn't. 211,000. That's what a survey-grade orbital relay array costs when you're the man who told the client to hold position while a shear front collapsed on top of it.

1:00The review board called the decision negligent. I called it a 5050 read. The broke wrong. Which is the same thing, apparently, when you don't have the institutional weight to argue otherwise. They pulled my license, seized my survey ship against the judgment, then offered me the specifics of my options. Fly scrubbers until the liability was paid, or default into labor arbitration, which meant flying scrubbers for someone worse. I signed with tecton because their hazard multiplier was triple the standard rate. Gary on Basin. The contract nobody wanted. Two million dead. That was the official number. 400 floating platforms in the lower atmosphere of a gas giant designated only by its corporate zoning label. The consortium that operated the methane extraction project hadn't even given the planet a name, just a basin code. 18 months ago, a rival outfit deployed a flesh-eating aerosol into the lower cloud bands during

2:00a territorial dispute over extraction rights. Aerosolized biological agent. Disolved human tissue on contact. The hazard brief called it host selective, tuned to human epithelial markers, much slower against most livestock tissue. The distinction had been a footnote in the casualty report. The consortium declared total biological loss, settled the territorial claim in closed arbitration, wrote down the platforms as salvage, then created tecton atmospheric as a clean-up subsidiary. The scrubbing contract existed to filter residual aerosol from the lower bands so the consortium could eventually recolonize. That was the stated purpose. Pilots were paid by volume of gas processed, 11 hours a day, six days a week during each three-week rotation. The job listing said atmospheric filtration operator. The ship said the rest. I flew a vacuum barge. Its official designation was Class IV atmospheric scrubber, but there was nothing to designate.

3:04It was a tube with engines on one end, intake grinders on the other, a filtration stack in the middle. Twin rows of ceramic radiator fins along the belly to shed the heat the filtration process generated. It was bottom heavy by design and built without armor. Manoeuvre ability barely deserved the word. The forward camera was a 40-year-old CCD unit with a resolution that would have embarrassed a doorbell. The nav software was locked to a proprietary rooting grid that updated once per rotation from an orbital relay. Locked meant restricted. There were zones it wouldn't map. The coordinates inside them disappeared even though the barometric chart said the atmosphere was there. The company called this the salvage blind protocol. The contract language said it was to prevent unauthorized recovery of surviving colony assets. What it meant was that if I saw something the company didn't want me to see, my own ship would pretend it wasn't there.

4:06I hated the camera most. A survey pilot's eyes are his instruments. Pressure and sheer front charting depend on high resolution visual correlation with atmospheric data as does thermal column identification. Tecton had given me a camera that couldn't resolve a platform outline at 400 meters. If I'd had my survey rig, I'd have been able to read boat patterns on an iron girder from twice that distance. Instead, I had 40 lines of grey grain on a screen the size of a paperback book showing me cloud. Always the same view. The four strings made up the difference. Or tried to. They hung above the pilot's seat from a crossbar bolted to the bare ceiling. Four thick steel guitar strings each waited with a heavy sinker cast from lead. The longest string carried a slug the size of a child's fist. The shortest one, a sinker about as big as a shotgun shell. The crossbar only looked simple.

5:07Each string anchor passed through a bell crank into an aneroid capsule fed by an exterior static pressure port. No electronics between the atmosphere and the metal. Because electronic altimeters drifted inside the planet's iron-charged lightning storms, sometimes by hundreds of meters, sometimes into complete gibberish, the strings were the pilot's actual depth gauge. As the outside load rose during descent, the capsules compressed and changed the tension on the strings. The sinkers made those changes audible through the bare ribs. The second string picked up a low vibration around 800 millibars. Past a thousand, the lowest dropped into a bass drone. A surveyor read depth the way a musician reads tuning by ear and through vibration in the seat frame, down to the way a lead weight trembled when a capsule pulled its string tight. I listened to the strings the way I used to listen to my survey instruments. They were the one honest thing in the cabin.

6:09I crossed the 600 millibar line 20 minutes into the shift. The upper bands fell away above me. Thin navigable atmosphere used by the supply shuttles with the transfer station suspended higher in the band. Low me was the work zone. The mid bands where the aerosol residue was thickest, where the filtration volume was best. They were quiet at this depth, just a low shimmer from the second string as the mix began to resist. I started the intake grinders. The frame vibrated as the rotary teeth engaged. Toxic smog pulled through the forward intakes, passed through the filtration stack, came out the aft vents as gas marginally less poisonous. My volume counter ticked upward through the first two cubic meters. The pay was in the volume. The cabin pressure made my ears hurt. Even the empty screen was just texture. I tried to raise Carlson on the radio at the top of the hour. Standard check-in.

7:11Carlson was the only other pilot on this rotation. He flew one identical to mine, working a sector about 12 degrees lateral in the same band. He'd been on the Gary On contract for eight rotations, nearly six months, which made him either the most experienced pilot tecton had, or the most desperate. Both, probably. At 61, with a bad knee, he had lasted longer than anyone else on the contract. He mentioned his wife, Carol, in every third sentence, what Carol packed in the supply drops, what Carol thought about the transfer station food. I'd known him three weeks. I knew more about Carol than I knew about him. The radio gave me static. Iron lightning crackled through the midband frequencies, turning Carlson's signal if he was transmitting into a wash of interference. This was normal. Below the 900-mB line radio contact was a matter of luck and timing. I'd hear him when the storm shifted, or I wouldn't.

8:13I dropped lower. The second string picked up a slow, heavy vibration, 800 millibars. The volume counter climbed faster. Conditions at this depth pushed more gas through the intakes, which meant more pay per hour. The barge groaned around me. The side ribs flexed. It was built for one thing, being cheap enough to lose. I processed volume for three hours. Their pitch changed as I adjusted depth, dropping to chase denser bands, climbing when the load began to stress the panels. This was the work. This was what 14 more runs of this felt like. The camera showed grey while the nav screen held me inside the approved corridor. On the volume counter, I could almost see the debt falling by the dollar per cubic meter. Then the grinder efficiency dropped. It came down 4% in under a minute. The intake mesh was clogging on something denser than the airborne particulate the grinders were designed to process.

9:15Fibers. The filtration readout registered a spike in organic content that didn't match the aerosol profile. Aerosol residue was protein-based, yes, but dissociated. Disolved tissue and cellular rubble from what the weapon had done to two million bodies. What the sensors were picking up was structured, with intact cellular architecture and vascularisation. Selling cells were in my intake. I should have climbed. The contract was clear about solids in the grinders. Anything that wasn't vapor counted as foreign object ingestion and tecton deducted for machine misuse per gram recovered from the intake mesh during post-rotation inspection. The smart play was to climb to cleaner bands and protect my pay by processing volume in the mid-bands, where the organic content was low. With the surveyor in me, the part that hadn't been revoked along with the license, couldn't stop reading the filtration output.

10:16The organic content was getting denser. The cellular structure was consistent, repeating, as though I was dragging my intake through the edge of a large organic mass. The composition was shifting too. My atmospheric analyzer showed nitrogen-oxygen ratios climbing toward breathable range. They had not reached it, but they were closer than anything in the aerosol zone had a right to be. I watched the numbers when I should have been watching the volume counter, then dropped another 50 millibars. The lowest string woke up. It had hung dead since the beginning of the shift. The big sinker suspended from its cable, too heavy to respond to anything above the thousand millibar line. Now, it moved. A low grinding drone against a metal rib that I felt in my mollas. The gradient had changed. Not much in absolute terms, but the capsule was loading the string differently from the descent profile I'd been hearing for hours.

11:16I knew that kind of break from survey work. A stable boundary layer. A stable pocket below me was holding against the surrounding atmosphere instead of letting both composition and load grade smoothly with depth. The filtration readout told me what was inside it. A pocket of breathable air. Nitrogen 78 percent. Oxygen 21. No aerosol signature. Clean air sitting in the middle of a zone where every living thing had supposedly been dissolved 18 months ago. I cut the grinders. In the silence that followed, the lowest string droned on. Through it came a sound I might have missed with the grinders on. A low rhythm carried through the hull, like the breathing of something with lungs the size of a building. The sensible thing was to climb. I descended. My reasons were the ones a man gives himself when the honest reason is that he needs to know. The intake mesh was clogged. If I didn't clear it, I'd lose grinder efficiency for the rest of the shift, costing

12:19me volume and pay. Another run would get tacked onto the 14. To clear the mesh, I needed to identify the source material. To identify the source I needed to get closer. Clean logic. Each step supporting the next. The fact that I'd already dropped past the depth where the logic required me to stop was something I handled by not calculating it. The strings told the story. The second and third strings were both vibrating now. The second held a steady buzz. The third picked up an intermittent rattle that meant compression waves. A large mass was displacing the layer below me rhythmically, sending compressions upward through the atmosphere. The lowest string had settled into its drone, which told me the reading at this depth was holding inside a narrow band. Whatever was producing the breathable pocket wasn't a transient eddy. It was sustained. Through the camera, 40 grey lines of useless resolution, I could see shapes below.

13:21At first I thought they were wreckage. The colony's floating platforms had been anchored at various depths by buoyancy tanks, most of which would have failed by now, so wreckage sinking to lower altitudes was expected. The nav software refused to map them. The camera couldn't resolve them. But the shapes were there, darker than the surrounding smog, angular. And one of the shapes moved. It flexed. A dark surface perhaps half a kilometer across rippled from its centre outward as a membrane would under pressure then drew back. The air frame flexed when the compression wave hit two seconds later. The strings jumped, with the lowest sinker swinging three inches to port. I was looking at tissue. It took me another minute of descent to understand what I was seeing because the scale was wrong. Swinging teaches you to correlate visual data with atmospheric readings to build a mental model of what's in front of you when your instruments can only give you pieces.

14:23The dark shapes stretched between the remains of a platform, buckle-dye and girders, the kind used in heavy industrial construction, still holding position because their buoyancy anchors remained partially functional. Strung between these girders, hanging in great sagging curves like cargo nets were biological sheets. The purple brown sheets shone wetly. Even the garbage camera could resolve their wrinkled surface and the raised ridges laid in parallel lines across the membrane. The sheets were breathing. That was the rhythmic sound. The compression waves. Each barometric fluctuation in the gas giant's atmosphere. The tidal pressure cycles that squeezed the lower bands every few hours triggered a contraction in the membranes. They pulled tight, drawing the surrounding toxic smog across the upper surface. Then they relaxed. And through narrow slits along the drainage ridges, they wept warm condensate and a thinner stream of processed gas into ductwork beneath them.

15:27I was looking at industrial lungs grown in vats. The kind of biological stock the colony would have had access to through its agricultural operations. The wine-derived organ tissue scaled up in growth vats to industrial dimensions stitched together at the seams with what looked like surgical staple lines visible even at this resolution. Acres of it. Hung beneath the wrecked platforms like curtains in a cathedral nobody had built for worship. The hazard sheet footnote came back to me. Host selective meant human tissue went first while livestock tissue lasted longer. When I saw the rest of the machine, thick process hoses connected the membrane ridges to old habitat atmosphere trunks along the frame. Pumps cycled in there. Heat exchangers too. Their radiated geometry showed through the grain when the lightning flashed. The curtains weren't somehow turning methane into 21% oxygen.

16:27They were the exposed biological filter, taking the aerosol where a mechanical intake would foul while whatever remained of the platform's life support plant reclaimed and mixed the gas underneath. The biological filter stayed outside while machinery worked underneath. Together they separated the poison from the human mix below. That made the scale worse, not better. It meant this wasn't one miraculous organism that had happened to survive. Somebody had maintained the pumps and nutrient flow through acres of grafted tissue. The seams had been replaced too. The clog in my intake made sense now. I'd been flying through the edge of one of those membranes. My grinders had been chewing on the part of the system that sealed the pocket. I cut the engines to minimum thrust, let the craft drift on the local currents. Below me, through the weeping curtains lay the breathable pocket, a volume of clean air roughly a kilometer across, sitting beneath the membrane canopy, a bubble trapped under

17:31a sheet of skin. Closer now, I could tell the hanging sheets didn't end at the canopy edge. Their lower skirts folded inward and overlapped against the old frame, making a loose sealed envelope rather than an open roof. The membranes held the poison out. The pumps and reclaimers circulated the human mix. If either stopped, the pocket went with them. I sat with the engines idling and the strings droning around me before a sight that two million death certificates said was impossible. Then the radio crackled. Carlson's voice, broken by static, beginning in the middle of whatever he'd been saying before he keyed the mic. Volumes better up here today if you want to come up, running about 12% above yesterday's rate. I keyed the mic. Carlson, I'm at 1100 millibars. My intake pulled structured, vascularized tissue, and I'm reading breathable air down here. I'm at 1100 millibars. A long wash of iron lightning that turned his response into a crackling mess, then he came

18:34back, the reception clearer, each sentence arriving with gaps between them where other sentences should have been. Sensor drift. You get that below a thousand. The iron charge throws the gas analyzer off. I've seen oxygen readings jump to 40% down there, which, you know, would turn every spark into a fire hazard, and I'm still here, so. He paused. Come up. Midbands are paying fine. The tissue in my intake isn't sensor drift. The intake pulls garbage. You know that. Colony waste and platform insulation, even biological residue from the... From what happened. Every run there's rubble in the mesh. That's why they deduct. This was a live, Carlson. Another pause. Static filled it. When he came back, he skipped my last sentence entirely, as though he hadn't heard it. The gap had been too long for a man who hadn't heard it. I've been on this contract eight rotations. You know what I've learned? The midbands pay.

19:36The lowbands cost you money and give you weird readings. Come up and run your volume, then go home. A beat. Carol sent those meal packets on the last supply drop. The ones with the dried apricots in the rice. I'll leave you a box at the transfer station. He was telling me about meal packets. I was looking at lungs the size of a city block, strung between the bones of a dead colony, breathing clean air into a pocket where people were supposed to be ash. He was telling me about dried apricots. The instruments said breathable. That made the pocket livable, which meant someone down here was living. You've seen them, I said. The radio hissed. For five or six seconds, Carlson's channel was open but silent. I could hear the background noise around him. His own strings resonating at a higher pitch, the rattle of his filtration stack. He was in the midbands where he'd told me to be, where he stayed. Come up, Ryan and run your volume. That's what we're here for.

20:37He cut the channel. Below me, the membrane's flexed. The drainage valve's wept. Movement crossed the iron girders. I was pulling into a slow climb when the first harpoon hit. The sound was a crack against the port side sharp, followed by a grinding vibration that shuddered through the entire airframe as a magnetized anchor locked onto the plating. I felt it in the controls, a sudden drag in that direction as though someone had hooked a cable to my ship, because someone had. The lowest sinker slammed against a metal rib hard enough to dent the metal. The second string whipped into a high frantic buzz. I was being pulled sideways. I could feel it through the seat, through the control yoke. A lateral force, steady, increasing. A winch. Someone was reeling me in. I shoved the throttle forward. Both engines surged. The craft lurched against the cable's pull, shuddering, the plating groaning where the magnetic anchor gripped. On the screen, a dark cable stretched torqued from my side down toward the structure,

21:40disappearing into the iron framework where the membrane curtains hung. The second harpoon came from the other side. I didn't hear the launch. I heard the impact. The harpoon had punched through the aft maintenance panel. Inside, a line let go with a rising hiss that ended in a wet sputter. The primary feed crossed the aft maintenance bay, three inches behind the panel. The harpoon had opened it. The gauge dropped as I watched the leak open. The fighting the first cable's drag began to slow as the feed dropped. Two anchors pulled in opposite directions, making the airframe pop at the stress points. At the edge of the breathable pocket where the iron girders met the membrane canopy, there were figures. The resolution was terrible. The same useless grain I'd been cursing all shift. But the figures were close enough now.

22:42The cables were reeling me in, closing the distance, that even the garbage camera couldn't hide what they were. They moved quickly along the girders, planting their feet on the narrow iron without hesitation. Their bodies had been altered with deliberate purpose. Their skin, except it wasn't skin anymore, had become a dark gloss sealed over the musculature beneath. Hair and loose features were gone. Their faces retained human topology, without anything that made a face readable. Clear pressure lenses covered lidless eyes above a jawline, sealed in dark coating with the teeth left bare. One of them was operating a winch. A cable drum mounted to a girder crossbeam positioned to cover the approach lane I drifted into. His hands on the winch handle were bare muscul wrapped in a dark coating that shone when the distant lightning caught it. A dark sealant, industrial hull sealant, the kind used for emergency pressure repairs

23:43on ships, cured over living flesh. At the base of his throat was a round opening where a larynx should have disappeared under skin, except there was no skin. A metal collar had been set into the sealed flesh around it, a pressure fitting repurposed into anatomy. A narrow breathing hose connected the collar to a pressure bottle strapped along his spine. He turned his head toward another figure, a valve in the fitting flexed, sending a low brass note through the structure to me. The second figure had a squat thermal scope braced against one shoulder. Old rescue gear probably. Its sensor tracked across my hull and stopped on the radiator fins. They might have done the sealing to themselves, somebody else might have done it while there was anesthetic and people available to finish before they lost the chance. I couldn't tell from 40 grey lines. I could tell what the repair materials were, platform sealant and pressure fittings.

24:43At the winch operator's shoulder, a pale band of vat-grown graft tissue showed beneath the black coating where two surfaces met. Too smooth for scar. Too uniform for anything grown on a man, the same host selective loophole as the curtains cut down to the scale of a body. Whatever had been available when human skin stopped being a survivable surface. I had seconds before the cables dragged me into harpoon range of a third rig being loaded on a lower girder. The thermal scope never left my belly. None of the rigs were aimed at the cockpit. They wanted me stopped, not blown apart. That distinction was the only reason I was alive. I overdrove the port engine. It was the kind of decision that kills ships. Asymmetric thrust on a bottom heavy barge with two cables pulling against the airframe. The port unit screamed. The starboard engine at standard thrust became the pivot point. The bow slu-ed hard to starboard, spinning against the first cable's anchor.

25:47The magnetic clamp on the port side held for barely two seconds before the plating beneath it tore free. A strip of plating roughly two meters long ripped away with a sound like a sore going through sheet metal. The cable went slack. I lurched free on that side spinning. The second cable, the one attached to the harpoon in my aft maintenance panel, went taught as the spins snapped it against my momentum. The cable broke. I felt the release, the sudden freedom of a ship no longer being held. I was free trailing fuel and rubble. A strip of port side plating was gone. The aft maintenance panel was breached. The feed open, the gauge dropping in steady increments that I could now translate into hours. Four hours, perhaps three. Depending on what else the harpoon had damaged that I couldn't see yet. I killed the port unit, brought the starboard to standard thrust, stabilized the spin. The sinkers rattled from the violence. On the screen the structure was falling behind me.

26:49The figures on the girders were visible for another few seconds. Then the grain swallowed them. I was climbing slowly while the fuel drained. The black shear was 30 degrees off my port quarter. I'd tagged it on descent, a narrow column of ammonia-rich condensate cutting down through the atmosphere. Visible on the infrared sensors as a blue slash in the warm smog. Surveyors mapped black shears as navigational hazards. They moved fast. Where ammonia droplets and ice were far colder than the surrounding atmosphere, swamping an infrared picture. The down draft itself could drop a ship 2,000 meters in minutes. The logic was simple. The ceramic radiator fins were still shedding heat, and I'd just watched a thermal scope follow them. The column could cool the surface until the scope lost me. It would also coat the viewport in ice and drop the cabin temperature below what my heating system could sustain on the fuel I was losing. The static ports would freeze with it, taking my best depth gauge and leaving me with degraded

27:54electronics, plus whatever strength remained in the damaged airframe. I turned into the black column. The transition was instantaneous. One second I was in the thick warm smog of the lower atmosphere. The next, ammonia-condensate hammered the ship's skin with the rattle of gravel, and everything changed at once. The surface temperature plummeted. I watched the temperature gauge drop through 60 degrees in seconds. The viewport went opaque. Blue white frost and ammonia ice spread from the edges inward until I was looking at a wall of frozen condensate 2 inches from my face. The cabin temperature followed it. My breath fogged. The moisture on the instrument panel froze into a white film. The exterior pressure ports iced over. I heard the last pressure capsule in the crossbar snapped to a stop. The strings held whatever tension they'd had at that instant. The sinkers hanging uselessly beneath them.

28:54The pitch froze with the capsules, taking my depth information. The one instrument I trusted was blind for the same reason I was. I dropped. The column was a down draft. The wing inside it fell, caught in the descending column, accelerating toward the crush depths in the deeper bands. I was falling, blind, without my depth gauge, venting fuel through a harpoon hole in my aft section. The electronic pressure gauge still worked badly, and the reading scared me. The gauge climbed from 1100 to 1,300 mB. The craft was built to hold cabin pressure in when the outside got thin, not to serve as a submarine when the outside got heavier. Every 100 millibars erased more of the margin between rated differential and buckling metal. I fought the controls. The starboard unit still had power. The feed breach was in the port system. The starboard drew from a separate tank.

29:55I had thrust. I had one engine on a ship designed for two. I angled into its lateral gradient, using the single unit to push toward the column's edge, where the down draft was weakest. It was like trying to swim across a waterfall. The down draft dragged me down while the engine shoved sideways. I settled into a diagonal fall, still descending, but slower as I drifted toward the margin where I might find calmer air. The pressure gauge read 1400 millibars. The airframe popped with a knuckle crack amplified around me. A stress fracture had opened somewhere. I couldn't inspect the exterior from inside. I couldn't see anything except the blue ice on the viewport, my own frozen breath. The instruments telling me I was deeper than any class four was rated to go, 1500. The walls compressed inward by a centimeter. The slight Boeing of the panels showed it, along with the way the rivets dimpled. The air inside thickened until my ears felt packed with clay.

31:00Then the column released me. The down draft thinned. The surface temperature began to climb slowly as the ammonia coating started to sublimate. I was still falling, but the rate was human now manageable. The starboard engine pushed me clear of the column's edge. I was in open atmosphere again, far below the rated bands but out of the sheer. The pressure ports began to clear. One capsule moved, then another. The lowest sinker began to move, swinging before it settled into a low vibration that told me I was below 1800 mB. Crushed territory for a class four in good condition. Mine was not in good condition, but the radiator fins were cold. The passage had stripped most of the heat from the surface. For the next hour or less my thermal profile would sit close to the surrounding atmosphere. A salvage rescue scope would have trouble separating me from the weather. I was hidden. Freezing, damaged, deeper than I'd ever flown on any planet.

32:04Blind behind a viewport still crusted with ice, but hidden. I sat in the frozen cabin with my arms wrapped around my chest. The lowest string droned while the fuel gauge dropped. Somewhere above me in the breathable pockets maintained by living membrane curtains. The colonists who should have been dead were pulling in my harpoon cables and waiting for the next ship that didn't know what Carlson knew. What Carlson knew? What the low resolution cameras were built to keep the rest of us from knowing. I watched the fuel gauge. I counted the hours I had left. The way a surveyor counts the variables before a sheer front call. The answer was simple. The options were not. The port fuel gauge read 19% – dropping. The intact starboard system, feeding my only working engine, sat at 43. I worked the figures the way survey school taught me, factoring atmospheric resistance and the vertical distance to navigable bands against available fuel and thrust.

33:08Starboard thrust alone could reach the upper atmosphere. Barely, if the weather cooperated and nothing else broke. The damaged port tank would be empty in about five hours whether I used it or not, because fuel was venting through the harpoon hole at depths that would crush me long before then. I needed to fix the feed or slow the leak until the port unit could come back online, so I had two engines for the climb instead of one. One unit could get me out in calm conditions, those never lasted below a thousand millibars. The aft maintenance bay was behind the cabin bulkhead. A crawl space roughly a metre high spanning the full width designed for access to the filtration stack, the grinder housings, the fuel line junction. The access hatch was in the floor, four bolts, a pull handle. The bolts hadn't been touched since the last depot rotation. I worked them with the torque wrench from the maintenance kit, the only kit teched on

34:09provided, two adjustable wrenches, hex keys, a roll of pressure tape, wire cutters, the torque wrench, a bag of compression clamp sized for the grinder housing, a set of replacement gaskets for the intake filters, tools for keeping the intake system operational, nothing for fuel line work, the bolts fought me. My hands were stiff from the cold. The interior temperature remained below freezing, the residual chill from the passage working through the metal around me into every surface I touched. The third bolt sheared its head. I stared at the broken stub for a few seconds, then hit the hatch with the heel of my boot until the panel bent far enough for me to wedge my fingers under the lip. I pulled it up. The crawl space opened below me into cramped darkness, so cold my breath formed crystals in the emergency lamp. I went in feet first. The fuel line followed the starboard wall of the crawl space, a pressure tube about two

35:12centimeters in diameter, clamped to the ribs at half meter intervals. The damage was visible from inside. The harpoon had punched through the panel and insulation before tearing into the fuel line itself. The puncture was ragged. The magnetized tip had torn rather than cut, opening a split in the tube about four centimeters long. Fuel seeped from it in a thin, steady stream that tracked down the rib and pulled along the lower shell beneath me. It remained pressurized by the damaged tank. I needed to isolate and seal the damaged section so it could hold under operating load. With a pipe cutter and splice sleeve, the job would take 20 minutes. With intake filter gaskets and grinder housing clamps, it was going to take whatever I could make it take. I cut a gasket into strips. The synthetic rubber flexed around the tube and was rated for chemical exposure from the filtration process.

36:14I wound three layers around the split section, then set two compression clamps over the wrap. The clamps were designed for a grinder housing twice the diameter of the tube, so I bent the inward with the wrench until they bit down on the smaller tube. The metal edges of the clamps dug into the gasket. The seepage slowed. It didn't stop. A thin film wept through the wrap, but the flow was a fraction of what it had been. I lay in the crawl space for a minute after finishing, my back against the hull, the cold metal pressed through my flight suit. From there I could feel the panels flex under the outside load. The starboard engine's vibration came through the ribs beneath a continuous groan as the gas pressed in from above. The stress fracture I'd heard during the descent was somewhere nearby. I couldn't find it. I could feel joint shifting that should have been rigid. The radio crackled while I was climbing back up.

37:16Carlson. Ryan, you on channel? I pulled myself through the hatch, grabbed the mic. I'm here. I've been calling for 40 minutes. You go dark on me. I start thinking about the paperwork. I was in the crawl space repairing the fuel line. A pause. When he spoke again, he went straight to rubble, skipping every question about how the feed had failed. You hit rubble? I was harpooned by people, Carlson. You know what's down here. The iron lightning was lighter at this depth. The ammonia from the down draft had disrupted the local charge distribution, clearing a temporary window in the interference. I could hear Carlson's strings at their higher pitch. Equipment rattled around his ticking volume counter. He was working, watching his figures. The deep noise, he said. That's what I call it. You pick it up on the radio sometimes in the lower bands. Brass sound like a horn section warming up a long way off.

38:20It comes through the static when the storms drop. I heard it my second rotation. Started staying above 900 after that. I saw the metal collar at the winch operator's throat again. Herd the note come through the girder when he opened it. They're people. They're the deep noise. I don't know anything else. And I don't want to. Carlson, they stripped two harpoons into my ship. They ruptured my fuel line. They were standing on a platform wrapped in long membrane the size of a parking lot, breathing air that should be poison. They're the colonists. They survived. He didn't answer for a long time. His volume counterticked. I could picture him in his compartment, identical to mine. The same bad camera and bare ribs with lead weights overhead. The same company that had put us both here with instruments designed to show us less than what was there.

39:21Carl worries about the deep noise, he said. I told her about it once, early on. Shouldn't have. She brings it up on every call now. What is it, Jim? Is it dangerous, Jim? I tell her it's atmospheric resonance. Gas layer boundaries producing infrasound. It's very stopped. That's what the manual says it is. Page 42. Atmospheric resonance consistent with layer boundaries. The manual. Pilots operational guide, section seven. Tech to an issues it with the contract. There's a whole paragraph about infrasound in the lower bands. It explains how to recognize the sound and calls it harmless. Then it tells you not to adjust your operating depth in response. He wrote that paragraph, Ryan. Somebody wrote it because somebody knew pilots would hear the noise and ask questions. Page 42. A harmless explanation waiting in print before a pilot ever heard the thing it was meant

40:21to explain. How far up do they come, I asked? I've heard the brass sound as shallow as 950. Never up in my 850 band. Whatever they breathe, it's down in those pockets. They stay near the membranes. Eastern sectors? The eastern sectors acquire to. Most of the platforms drifted west after the buoyancy failures. Eastern side is thinner, fewer structures, fewer of those membrane sheets. If you're trying to find a corridor, go east, but the shears migrate, so don't trust a lane that was open yesterday. I need a route up, I said. My ship is cold from the shear, but the fins will start shedding heat again inside an hour. Once I'm radiating, they'll see me. How's the repair? It'll hold at low thrust, maybe, but it won't hold if I push it. Then don't push it. Climb slow to the east and keep quiet. The convective season's been building. There's warm cells forming in the eastern basin.

41:22If one kicks up while you're in the right position, ride the updraft. Let the weather do the work. The gauge is red 17% on the damaged side, dropping more slowly. The gasket wrap was holding, starboard at 41. The viewport was clearing in patches as the blue ice sublimated, showing me the dark atmosphere outside the color of pressure. Carlson, you should climb too. I'm at 8.50, I'm fine. The one I rode down, it migrated. The whole pattern shifted when I punched through the lower bands. If the hunting range moves with the local currents, I'm at 8.50, he said again. I've been at 8.50 for eight rotations. Eat the apricots. I'll see you at the station. He cut the channel. His volume counter was the last thing I heard, ticking on. I sealed the crawl space hatch with pressure tape. The broken bolt bent flat under the wrench before I strapped myself into the seat.

42:24All four sinkers were fully thawed now swaying above me. The lowest one held that low vibration, 1800 millibars, still in crush range but steady. I brought the port unit online at 10% thrust. The repair held, I increased to 15. The repair wept around the gasket edges, but the rate was manageable. With both engines available, I held the repaired side at 15% and starboard at standard thrust. I began to climb. I climbed for an hour through blank haze. During that climb, the gauge passed 1500 millibars and fell toward 1300. The airframe strained eased as the density fell above me. The walls flattening back toward their proper shape, the rivets, unpuckering. The missing port side plating left me out of trim. Every few minutes I had to feed in a little starboard correction and watch the intact tank pay for it.

43:25The viewport cleared in stages, patches of ice falling away until the distant flicker of iron lightning showed through haze to the west. The strings loosened as I rose. The lowest sinker settled from its warning drone into something almost peaceful. The temperature gauge was the clock I couldn't ignore. The shear had brought the ship's skin down to minus 90. Every minute in warmer atmosphere bled that cold away. The ceramic radiator fins designed to shed heat from the filtration process were efficient at their job in both directions. They cooled fast in the shear, but they warmed fast in open air. I watched the temperature climb past minus 70 and keep rising toward minus 50. At minus 40, my profile would begin to separate from the ambient atmosphere on the kind of thermal scope I'd seen below. But minus 20, the radiator rose would be bright targets again. I had about 30 minutes.

44:26The eastern sectors were thinner, Carlson had said. Fewer platforms, fewer curtain structures. I'd been angling east since the climb began, putting distance between myself and the cluster where the harpoons had come from. The nav software showed me my approved corridor, a narrow lane through the atmosphere that the company's rooting grid allowed. The corridor was north-south. I needed to go east. The software wouldn't let me plot a course outside the corridor without a root override code I didn't have. I flew east anyway and ignored the corridor deviation warning flashing on the nav screen. At 1200 mbps, 20 minutes into my 30 minute window, I passed another platform. I didn't plan to pass it. The nav corridor had been routed to avoid it, which was why I was outside the corridor. The platform sat in one of the software's restricted zones, the areas it refused to map. From inside the approved lane, I'd never have known the platform was there.

45:30The camera would have shown blank cloud while the nav screen showed empty space. I'd have climbed past at a comfortable distance, blind, because the route kept me compliant. From outside the lane, at 1100 m lateral distance, the platform finally separated from the haze on the camera, while the infrared display filled in the moving heat signatures. The platform was larger than the one where I'd been harpooned. A main deck structure roughly 300 m across. Its buoyancy tank still holding it at a stable altitude. The iron gurdow work beneath it supported a curtain system twice the scale of the first. Membrane sheets hung in enormous loops, and their drainage valves produced a visible mist of breathable moisture that fogged the space below the platform in a warm haze. The tidal contraction cycle was mid-phase. The curtains pulled tight as they drew in smog.

46:31Barometric compression flexed the entire structure inward with a slow, massive rhythm I could feel through the seat. The scavengers were on the deck. Dozens of thermal signatures moved across the exposed surface, clustering around cable rigs and curtain anchor points, while larger shapes shifted between the stockpile and the curtain supports. At a split membrane seam, two signatures stayed close, while a warmer feed line moved toward a pale graft section. They were building out the curtain infrastructure. The new membrane area extended the breathable zone beyond the older supports. Two scrubbers sat on the main deck. Or what was left of them. They'd been stripped to bare frames. Whole plating had been removed in sections along with the ceramic radiator fins. The engine housing stood cracked open for their components. Both filtration stacks and intake grinders were gone. Then I saw where some of it had gone.

47:33A bank of ceramic fins had been rebuilt beneath the membrane supports as heat exchangers. Their white edges visible between the folds. Inside a nutrient tank, one grinder housing fed directly into the vascular lines that supplied the curtains. Pumper assemblies from my own filtration stack had been bolted into the old habitat trunks. They weren't stripping scrubbers because metal was precious in the abstract. They were stripping them because the thing keeping them alive wore out. What remained on the deck were the skeletal outlines of ships identical to mine. There's four atmospheric scrubbers by their proportions and mounting pattern, the same model I was sitting in. Two ships. Two pilots who'd been out here doing what I was doing. Catalogged somewhere in the company's filing system as atmospheric casualties. The nav software left the corridor deviation warning flashing on the screen.

48:34I called up the rooting overlay. The map of approved corridors and restricted zones that the software used to guide pilots through Garyon. I'd looked at this map a hundred times. The restricted zones showed as blocks, areas the system wouldn't map or navigate toward. I'd assumed those blocks marked rubble fields or turbulence hazards the company had identified. I overlaid my actual position against the restricted zones. The passing structure sat beside it in real space. The restricted zone matched the platform's position exactly. Its block matched the occupied footprint down to the dimensions and orientation. A precision that couldn't be coincidence. The software knew the platform was there. The company had mapped it, then routed pilots around it. I pulled up every restricted zone on the routing overlay. Nine blocks were scattered across the lower atmosphere and each matched another occupied footprint.

49:35As the pattern held, they were occupied and maintained. Tektan had built the approved corridors through the gaps, keeping the cameras pointed at empty smog, maintaining the two million dead count one flight path at a time. And the dead count wasn't only a casualty number. Total biological loss was the premise under the closed arbitration that had settled the territorial claim and let the platforms be written down as salvage. Having colonists made those categories false, I knew what a judgement could turn into once an institution agreed on the category. I was flying mine. The temperature hit minus 40. I was becoming visible. I pushed past the platform. On the deck, some of the scavengers had stopped their work to watch me pass. The display showed several figures stop at the deck's edge as I slid by at 1100 meters. They didn't launch harpoons. I was probably outside their range.

50:36One heat signature lifted a narrow object toward me and held it there until the structure slipped behind. The stripped scrubbers told me what the harpoons were for. A class four could sustain their life support system for months if they pulled it onto a deck. I tried the radio. Carlson, come in, can you hear me? Static. Then his channel opened. His transmission was distant, degraded. The storm interference was building again as I climbed out of the ammonia-cleared zone. Behind his signal, buried in the noise, a sustained brass tone resonated through the static like a horn note carried on a long wind. The deep noise sat close in Carlson's background. Carlson. The shears shifted. The hunting pattern is moving up. You need to climb now. His response came in fragments. Volumes good today, Ryan. Carol's going to... Running about 16 per...

51:37His volume counter kept ticking. He kept working. Carlson, get out of there. Climb while you can. The brass sound grew louder in his transmission than his channel closed. A convective cell announced itself through the strings. The lowest sinker, which had been hanging at a comfortable angle in the thinning atmosphere, picked up a new vibration. A low rapid oscillation I'd felt before once, in my survey days. A thermal column building below me, warm gas rising from the deeper atmosphere and accelerating as it gained altitude, pushing upward through the cloud bands with a force that could reshape the weather across an entire sector. In survey work, we mapped convective cells as navigational features, columns of rising warm air that floating platforms used for altitude adjustments. I charted dozens of them. I'd never ridden one. I checked my position. The cell was forming below me to the east, exactly where Carlson had said the convective

52:42season was building. It would rise through my altitude within minutes. If I positioned at the column's edge as it passed, the updraft would carry the barge toward the upper atmosphere. Thousands of meters of vertical gain without sustained engine thrust, saving the fuel I couldn't afford to burn. The rising column would also flood the surrounding atmosphere with heat, washing out my infrared profile in a wall of warm gas. The sinkers confirmed what my instruments were too degraded to measure. The second string picked up the cell's pressure wave. A compression that quickened as the layer below me was displaced upward. The third string began to rattle. The big sinker swung wide. I angled east and cut thrust to idle. The gauges, port at 11%, the gasket wrap weeping but holding, starboard at 34. The climb worked only if the cell did most of the lifting.

53:42The cell hit my altitude like a wall of moving air. The craft lurched upward. My seat harness caught me. Loose objects around me, including the torque wrench and a water canister I'd forgotten to secure, slammed to the floor. All four sinkers snapped, taught, yanked hard toward the deck as the pressure wave hit the capsules and the ship accelerated upward. We were rising faster than the engines could have pushed us, beyond any controlled climb. The warm column barreled toward the upper atmosphere so quickly that my depth gauge became a countdown moving in the right direction. I fought to hold position at the column's edge. The sweet spot was narrow, too far into the cell. The turbulence would tear the ship apart. Too far out I'd lose the lift. The boundary between the two was a zone of violent shear. The rising column grinding against the surrounding band, producing cross winds that slammed

54:43me sideways with every gust. I held the yoke with both hands, with port at 15% and starboard at full. I slewed under each gust and I corrected after each one. The repair held for the first 2,000 metres. The 22,000 metres of vertical gain, the gasket wrap began to degrade. I could hear it. A change in the sound from the crawl space below, the wet sputter of the original leak returning as the compression clamps lost their grip on the smaller tube. The port gauge, which had been dropping slowly, began to drop fast. 1100mB, then 1050. The pressure eased as we climbed, but the fuel was draining away. I shut down the port engine. Starboard only now. A symmetric thrust kicked me off the trim I'd been holding against the cell's cross winds. I corrected. The column carried me, but the ride was getting rougher.

55:46As the cell rose into the thinner upper atmosphere, its energy dispersed, the updraft weakened while break-up turbulence worsened. The radio came alive. Carlson's channel. Open. Distance and the storms, iron lightning shattered the transmission, this high in the atmosphere. Through the noise, in pieces, I heard him. Hit me, cables, they. Carole, tell Carole, metal struck metal through his open mic. One impact, then the grinding vibration of a magnetic anchor taking hold. His engine note climbed until it distorted the transmission. Carlson, overdrive one side, make them tear the plate. Er, did, first ones off, second ones through the belly. I think they got the... A second grinding note swallowed him, followed by a bang that dropped his engine pitch. His emergency beacon appeared for half a second on the nav screen before the routing software masked the sector again.

56:49I caught the coordinates before the block covered them. Six kilometers west. Nine hundred meters below me. I could reach him if I left the convective column now. I ran the numbers. Starboard fuel was at 26% and falling. Port unit dead. Six kilometers lateral. Nine hundred down. Then whatever thrust it took to break two cables off Carlson's barge. If I left the cell, I would spend the free altitude I'd just gained getting to him. On one engine I could probably reach his position. Probably. Getting both ships back into the column was different. The yoke kicked in my hands as the cell tried to throw me out anyway. West was three degrees of turn. Three degrees, then more. I could put the barge across the boundary, trade lift for lateral speed and descend into Carlson's sector. My survey board had spent six hours explaining what a professional was supposed to do with the 50-50 read after everyone in the room already knew which 50 had happened.

57:52Carlson, can you hear me? The apricots. She puts them in because I asked, my first rotation. I told her. She's been putting them in every... Ryan. Then metal tore across his ship with a long shriek. The brass notes sounded behind him. Not one voice now but several overlapping through the static. His transmission broke apart. I held the yoke centered on the rising edge of the cell. I eased half a degree to starboard into the strongest lift. The convective column carried me through a thousand millibars, through 900, the atmosphere thinning around me. The sinkers going slack as the capsule's unloaded. Carlson's channel stayed open. Static. One brief engine surge. A cable drum winding. Then nothing. I climbed. The cell died at 700 millibars. The updraft collapsing into scattered thermals that buffeted me without lifting me.

58:54I was in the upper bands. My hands had cramped around the yoke so hard that opening my right one took two tries. The starboard unit drew on what remained in its tank, 21%. If I flew straight, it would carry me to the transfer station. The port tank was empty, and the repair had finally failed with the fuel line open and dry. As the blue ice vanished, the viewport cleared onto pale open atmosphere. The lightning was below me now, flashing in the bankside risen out of. The platforms and curtains were beneath me, hidden in the murk I'd spent six hours trying to escape. The sinkers hung quiet, barely moving in the thin air. The interior warmed as the surface temperature normalised, the frost on the instrument panel melting into beaded water that ran down the gauges in slow tracks. I radioed the transfer station. I gave them my identifier and position, then reported my fuel state.

59:58They assigned me a docking bay. The voice on the other end asked if I needed medical. I declined. He asked about Carlson. I said I didn't know. He said Carlson's beacon hadn't reported in four hours. I said I didn't know. The docking took 40 minutes. The transfer station was a pressurised platform in the upper atmosphere, a staging facility for the scrubber fleet, maintenance bays, fuel depots, crew quarters, a communications relay for the weekly upload to the company's orbital office. I brought mine in on the starboard engine alone. The portside dead, listing seven degrees to the left from the missing plating. The docking clamps caught me. When power shut down, the weights went silent. The post-flight inspector was a man named Harlan, who wore tecton coveralls with a clipboard tracker clip to his belt. He walked the exterior of my ship while I stood on the docking platform in the clothes

1:00:59I'd worn through the shift, watching him catalogue the damage. He photographed the harpoon hole and measured the missing strip on the portside. At the intake grinders, he pushed a probe into tissue lodged in the mesh teeth. The sample came free. He put it on a pocket scale before bagging it. He didn't ask what could grow vascular ridges thick enough to clog a class IV grinder. The number on the scale mattered first. He entered it on the tracker, a digital form with a pull down menu for damage categories. He categorized the harpoon hole as impact damage, an identified foreign object. The missing plating was stress failure, atmospheric loading. The tissue in the grinders was biological rubble, foreign object ingestion, chargeable by recovered mass. Each entry carried an automatic pay deduction. I watched my 14 remaining runs become 16.

1:02:02Harlan asked me what happened. I told him I descended below 1200 millibars to clear an intake clog, encountered severe turbulence and took whole damage. Then I entered a black shear for emergency cooling before climbing out on one engine. Everything I said had happened. I just left out who did it to me and what they'd become. He handed me the damage report form, standard post flight, four pages, most of it checkboxes, hull condition, engine status, filtration system, navigation equipment. The last section was a single blank field with a header, anomalous atmospheric observations. I sat in the crew quarters with the form on the table in front of me. The room was small, with a bunk and locker beside a desk bolted to the wall. Through the window, the pale upper atmosphere lay still while the supply shuttle from the orbital office approached on its weekly run.

1:03:04On the desk next to the form was the box of meal packets Carlson had left for me. Carol's rice with the dried apricots. He'd labelled the box with a strip of masking tape. Sadly, from Carlson, don't heat pass three minutes or the rice goes mushy. Carlson was listed as lost that evening. Atmospheric casualty, standard hazard event. Carlson's contract death benefit would go to Carol. Four months base pay, capped, no multiplier. His scrubber would be written off, its beacon deactivated. The company would post a replacement opening on the next contract cycle. The slot would fill. Someone with debt and nowhere better to go. The form waited with its blank field. Anomalous atmospheric observations. I was required to fill it in. Company policy, section 12, post-flight reporting obligations.

1:04:05Failure to complete all fields constitutes a contract violation subject to pay suspension. The field could hold everything I'd seen. The curtains and survivors. I could describe the adapted colonists with their sealed bodies and brass throat stomers. Their lipless faces alongside the harpoon rigs. The breathable pockets and stripped class four scrubbers on the platform deck could go in next. The nav softwares restricted zones matched platforms the company said didn't exist. All of it would fit. The form would go into the weekly upload to the orbital office, where a data clerk would file it, where a compliance officer would read it. The company that had built every instrument of my ignorance would process my report through the same system that had processed two million death certificates. My cameras were 40 lines of grey grain. My nav data was restricted by the company's own software. The physical evidence on my ship, the harpoon hole, the organic sample, was already categorized

1:05:10as rubble impact and foreign object ingestion. Every mark on my ship that proved what happened was, in the company's damaged taxonomy, proof that I'd mishandled the equipment. I had my word, an unlicensed surveyor's, with 200,000 in liability debt. I was flying a scrubber I couldn't afford to lose under a contract I couldn't afford to quit. I picked up the pen over the blank field. The form waited. I wrote, no anomalous observations. I put the pen down and closed the form. Then I sat in the crew quarters with Carlson's meal packets on the desk beside me. The supply shuttle growing larger in the window. The upper bands outside. Below me, below everything, the curtains were breathing. The drainage valves were weeping clean air into pockets where two million people had been declared dead by a company that signed my paychecks, processed my damaged reports, set my deductions, mapped my corridors and built my cameras to see nothing.
