Scout pairs launched within the hour.
Asha paired military with aberrant for each team. Her rule, not Raze's. "If we find something built by Devour-types, I want someone who reads that language next to someone who can shoot it." Nobody argued. The revelation about four hundred staged organisms had killed the appetite for debate.
Team one: Yejun and Jin, taking the eastern output channel through a drainage trunk that connected to the old transit hub.
Team two: Two troopers, the rookie and a woman named Seo who'd survived the siege with a cracked helmet and uncracked nerve, checking the northern channel via a maintenance shaft Goh's data flagged as recently widened.
Team three: Raze and Mira, heading west toward the closest surface-adjacent corridor, a condemned water authority tunnel that ran beneath district nine's industrial quarter.
Asha stayed at junction command with Marlen and the remaining guard. Dael held civilian coordination with Mun at the hub, monitoring Goh's cocoon temperature while she processed.
"Two-hour round trip," Asha said at departure. "Check in every thirty minutes by pulse relay. If you miss a check-in, I send extraction. Clear?"
"Clear," everyone said, because when Asha ended a sentence with that word, it wasn't a question.
Raze and Mira dropped into the western maintenance throat ten minutes later.

The tunnel smelled wrong before they reached the target zone.
Not combat-wrong. Biology-wrong. A thick, humid stink like a greenhouse left sealed for a month. Organic growth in stagnant air. Mira's silver eye caught the light from Raze's handlamp and glinted as she scanned wall seams.
"Growth medium residue," she said, touching a slick patch on the tunnel ceiling. Her fingers came away coated in something that looked like clear gel with dark threads running through it. "This is maturation fluid. The kind Goh described for sites three through seven."
"From the organisms?"
"From their casings. When a Foundry-built creature finishes development, it sheds a membrane layer. Like a butterfly, if the butterfly could crack your skull." She wiped her hand on the wall. "This is recent. Days, not weeks."
They moved deeper.
At the tunnel's junction with a collapsed utility access, the space opened into what had once been a water authority equipment room. Pumps rusted in their mounts. Control panels stripped of copper. A city blueprint still pinned to one wall, yellowed and curling.
The center of the room had been hollowed out.
Not by tools. By bodies.
The concrete floor was worn smooth in a circular pattern roughly eight meters across, polished by repeated contact from multiple large organisms resting, turning, pacing in the confined space. Along the walls, claw marks in groups of four scored the concrete at regular intervals. Territorial markers, Mira said. The ceiling showed stress fractures where something heavy had braced against it, testing the overhead geometry.
Three nest depressions ringed the perimeter. Each one held shed biological material: translucent membrane scraps, dried fluid, and small hard nodules that Mira identified as waste cores, the metabolic byproduct of organisms consuming growth medium to fuel final development.
"This was a staging point," Mira said, crouching by the nearest nest. "They matured here. Acclimated to surface temperature and pressure after the deep channel transit. Then moved on."
"How many?"
"These nests fit two each, maybe three if they're compact builds. But look at the floor wear." She pointed to overlapping track patterns. "Multiple rotations. This room processed at least twelve organisms over the last two months, maybe more, in batches."
Raze scanned the far wall.
"Where did they go?"
Mira followed the claw marks to a breach in the eastern wall. Not a natural crack. A clean-cut passage into what looked like a service corridor. The cuts were precise, measured, the same engineering-grade work they'd seen in Gael's feeder tunnels during the siege.
"Deeper into the district infrastructure," she said. "The service corridors connect to utility basements under every major building in the industrial quarter."
Raze crouched by a nest depression and picked up one of the waste cores.
That was a mistake.
The core was small, maybe the size of his thumbnail, but it was dense with residual energy. Concentrated biological output from an organism that had been fed pure growth medium from a Foundry maturation chamber. The moment his fingers closed around it, Devour woke up and screamed.
Not metaphor. His glands fired. All of them, the heat channels along his ribs and the pressure vents behind his ears and the newer ones growing along his forearms that he hadn't named yet. Every absorption pathway in his body oriented toward that tiny core like compass needles finding north.
His mouth flooded with saliva.
His vision narrowed.
He dropped the core. Picked it up again without deciding to.
"Raze."
Mira's voice from somewhere left of him. He could hear her heartbeat through the wall. Sixty-two beats per minute. Controlled. Healthy. The sound made the hunger worse because healthy meant strong and strong meant more.
He dropped the core again. Stood up. Walked three steps toward the breach in the wall.
Stopped.
Turned back toward the nest.
"Raze. Walk to me."
He couldn't make his feet point in the right direction. The waste cores in the nest glowed in his hunger-vision like coals in ash, and the maturation fluid on the walls called to him through his skin, through the new glands, through channels of absorption he hadn't known he'd grown.
Mira grabbed his collar and hauled him backward through the utility door they'd entered from.
He let her. His body didn't fight it. Some part of him still had the brakes on, just barely, and Mira's grip on his collar gave that part something to lean against.
She pulled him ten meters back up the tunnel and shoved him against the far wall, out of line of sight from the staging room.
"Breathe through your mouth," she said. "Smell makes it worse."
He breathed through his mouth. His glands kept firing for another eight seconds, then tapered to a low burn that didn't stop but became manageable.
"Talk to me," he said. "About anything."
"About the hunger."
"About the hunger."
Mira leaned against the opposite wall. Her knife was in her hand. Not pointed at him. Just present, the way you hold a tool while deciding if you'll need it.
"Eighteen months ago I spent six days in a collapsed substrate pocket with three dead hounds and no exit. By day two I'd eaten every core in reach. By day four I was licking the walls for mineral trace. By day six, when a maintenance seal finally corroded enough for me to break through, I couldn't remember my own name for about an hour."
She turned the knife between her fingers.
"The suppression thing you do — the push-it-down, compartmentalize, only-eat-when-I-choose method — works fine when your stress is predictable. Short fights, rest periods, controlled intake schedule."
"And when stress is continuous?"
"The method breaks. Not all at once. It degrades. Like a muscle you've been flexing for too long without release. The hunger doesn't get stronger. Your ability to hold it gets weaker."
Raze pressed his bandaged forearm against the cold tunnel wall.
"How do you manage it now?"
"I don't suppress. I redirect. There's a difference." She sheathed the knife. "Suppression is a dam. Redirection is a channel. You don't stop the water. You point it somewhere it can go without drowning anyone."
"Point it where?"
"That's the part you figure out yourself. Mine goes into tracking. Reading environments. My hunger wants to consume, so I feed it information instead of cores. Keeps the glands busy without the biological intake."
He stared at her.
"That works?"
"About seventy percent of the time. The other thirty, I keep a knife in my hand and stay away from populated areas until it passes."
She didn't dress it up. Didn't make it sound like wisdom. Just one Devour-type telling another what the road looked like from a few miles further on.
His glands settled to idle. The hunger stayed, it always stayed now, but the emergency volume dropped to a background hum he could think over.
"Thanks," he said.
"Don't thank me. Just don't eat me in my sleep."
He almost laughed. Didn't quite get there.
"We still need to check where they went," he said.
---
They went back to the staging room with Raze breathing through his mouth and keeping his hands away from the nest material. Mira took point, collecting samples in a sealed pouch while Raze mapped the exit routes.
Three breaches in the walls. Three directions. Each one cut with the same precision.
Mira found route markers at each breach — command varnish symbols, smaller than the claim marks from the vault but using the same visual grammar. She read them with her silver eye while Raze held the lamp steady.
"Designation codes," she said. "Each breach is tagged with a target type."
"Target type?"
"Infrastructure category." She traced the first symbol. "This one matches water systems. Pumping stations, filtration, reservoir access." The second. "Power distribution. Substations, transformer vaults, generator feeds." The third. "Supply chain. Warehouses, cold storage, distribution centers."
Raze lowered the lamp.
"It's not an army. It's an occupation force."
Mira nodded slowly.
"The Alpha isn't going to fight the surface. It's going to starve it. Four hundred organisms sitting quietly in the basements of every building that keeps people alive. Water, power, food. All it has to do is give one signal and everything stops at once."
"While Gael keeps the hunters busy with junction raids and processing depot strikes."
"The raids are noise. The Foundry deployment is the operation."
Raze thought about Marlen's city feed. District seven dark. District nine rotating blackouts. Hospital belt on reserve. All of that was Gael's surface disruption. The distraction layer. Underneath it, purpose-built organisms were already in position at the infrastructure that kept millions of people from dying.
If the Alpha triggered them, it wouldn't look like a monster attack. It would look like system failure. Pumps stop. Generators die. Cold storage warms. Food spoils. Within a week, the city would be in crisis. Within two, it would be in collapse.
And every hunter, trooper, and aberrant would be too scattered fighting surface fires to look for the things squatting in their basements.
"We need to get back," Raze said.
"Immediately."
They moved.
---
The return trip took twenty-two minutes at combat pace, Mira's injured arm slowing her on the vertical sections where both hands mattered. Raze wanted to carry her and didn't suggest it because she'd have cut him for asking.
At the tunnel junction where western maintenance met the approach to the main chamber, they hit the first sign of trouble.
The lights were off.
Not dimmed. Off. The metabolic glow that the substrate maintained even during the siege, that constant low luminescence that meant the node was alive and regulating, was gone from this section of tunnel.
Mira stopped.
"When did the glow cut?"
"Just now. It was on when we passed through an hour ago."
She put her hand on the wall. Drew it back fast.
"Stone's cold. Regulation dropped. Something pulled the node's attention elsewhere."
They ran.
At the chamber approach, the blast doors were sealed.
Full lockdown configuration — the same gates that had dropped during Goh's immersion protocol, now closed from the inside. Raze hit his comm.
Static.
He hit it again. Nothing.
Mira tried hers. Same dead air.
Through the blast door, faint and muffled, they heard the junction's perimeter alarm. Not the staged tones Asha used for wave warnings. A continuous high pitch Raze had only heard once before, during the initial shaft breach.
Full perimeter activation.
Something was hitting the junction from a direction they hadn't defended.
Raze slammed his fist against the blast door.
"Asha! Open the gate!"
The alarm screamed behind six inches of steel, and nobody answered.
