Inside Iron Vault Seven, a frozen zero-G cryogenic vault, Cryogenic Storage Unit Gamma-9 holds the Terran honeybee queens needed to restart a starving colony’s food chain. Gunnery Sergeant Valerii Petrov leads a mixed Eurasian Coalition and Federal Marine recovery team into Radial Arm Three, where the Threaded has turned the vault’s biofilm, doors, and dead recovery teams into a living trap.

They cut through sealed routes with thermal lances and move through vacuum gaps, failing comms, and container corridors where iridescent film signals their position. Then the previous recovery team begins broadcasting its own voices as a mayday lure, using memory and hesitation as part of the kill system.

Inside Iron Vault Seven, a decommissioned cryogenic complex fused to a Stilt-Lord reef, Unit 781 serves on a four-man observation detail at the edge of a dormant colony. The official mission is to monitor seismic activity and colony vitals, but the Golem soldiers are really there as a disposable tripwire if the vault wakes.

The Stilt-Lords do not hunt by sight. They listen through calcified walls, breached bulkheads, contaminated life support, and the vault itself, where a footstep can become a signal and a rifle shot can wake the neighboring bodies.

Beneath eleven kilometers of pressure ice, Tania Aggregator Two is a deep-ice refinery built to feed the Tania Borealis colonies with brine, fuel components, oxygen feedstock, and reactor salts. After a pylon shear floods Pump Gallery Seven-Alpha and threatens the oxygen liquefaction coils, Combat Engineer Matt Simmons and his squad are sent down the Anchor Trunk to secure the failing life-support heart.

But the confirmed Wire Mold infestation is not just growing on pipes. It is inside legacy fiber, suit telemetry, winch logic, firmware, and the coil systems, turning the refinery’s own machinery against the team. When the squad tries to stabilize the coils and pull Corporal Mears from the black sump, the Mold opens his purge valves and locks his suit around him.

Inside the flooded mineral-brine pump galleries of the Pressure Keel, the ballast regulator is failing after years of Reefwalker infestation. A clearance team, guided by passenger-species advisors and watched by a silent forward observer, is sent down to reopen access and restore the regulator before the whole system collapses.

The team begins with standard doctrine: scan the calcified barriers, burn through them, and push toward the lower galleries. But the Reefwalkers do not just occupy the space — their slurry reacts to pressure, hardens into new walls, embeds egg-cysts, blocks extraction routes, and slowly grinds through pressure suits with crystalline dental plates.

On the derelict orbital platform Kestrel’s Fall, a frozen cryogenic container yard drifts in zero gravity after years of damage, dead pods, failing seals, and broken emergency light. A combat engineer and an augmented fireteam enter Cargo Deck 7 to recover the cryogenic data archive from Pod 77-Alpha before the pod’s thermal regulator fails.

The Shearlings are not simply hunting inside the wreck. They mimic shattered pod debris, move by tail-snap physics, disable soldiers with sickle-claws and shearing jaws, then drag them into growth sites hidden deeper in the platform. One tower has learned to wear human armor and active distress alarms, turning every rescue instinct into another way to break formation.

On Kharon’s Tithe, a storm-locked weapons moon is being swallowed by the Fractofusus, a silent green organism spreading across the Tithe Coast. A denial platoon enters Foundry Seventeen to recover missile guidance matrices and disable the launch galleries before orbital quarantine fire closes over the coast.

The Fractofusus does not attack like an animal. It spreads through fragments, propagules, runners, water, machinery, seams, drains, and disturbed terrain — and inside the foundry, the still-moving conveyor system is carrying regenerated pieces deeper into sectors marked clean.

At Prym Refinery, a Graveclam has anchored itself over the primary fusion stack and turned the worker districts into calcified streets, toxic sludge, and yellow-gray vapor. Second Combat Engineers enter with a seismic lance team to unanchor GC-7 before the fusion stack turns the refinery basin into a poisoned crater.

The Graveclam does not need to chase soldiers. It breathes symbiont vapor into the refinery, leaving infected personnel outwardly rational enough to pass checks, give orders, approve false evac routes, and clear compromised survivors through command procedure.

On Iron Vault Seven, a failing cryogenic space station is being drowned from the inside after its lower levels flooded and became Drowner breeding territory. Squad Trench-9 is sent into the eastern wing to repair Corridor 12-Alpha, a leaking supply route needed by forty-seven soldiers trapped in Sector 12.

The engineers move a pressure-sealing crawler through dead bays, wet junctions, and damaged membranes, trying to restore atmosphere before the route collapses. But the Drowners are not just living below the station — their juveniles are chewing through junction seals, raising the water, and turning pressurized corridors into feeding ground.

With vacuum on one side and floodwater beneath their boots, the squad is forced to keep working inside infrastructure that is already failing.
