Mun found the trail forty seconds after everyone else failed.
Not with eyes.
With his palms.
He pressed both hands to the sealed floor slot and pulsed a low, rapid query into the substrate. The stone answered in tiny delayed echoes, each delay a distance, each wobble a turn.
Jin translated without breathing.
"Maintenance tube. South-west descent. Two branch points. One moving small mass. One moving heavy escort mass." She swallowed. "Small mass is alive. Panicked."
The father collapsed to both knees with relief and terror tangled together.
"Bring her," he said to Raze, voice breaking. "Bring Sori."
First time the child's name had been spoken loud enough to anchor the room.
Raze nodded once.
"I go now."
"No," Asha said. "You go with a team."
Yejun stepped forward before she finished.
"I lead point in tube spaces. Mira with me. Raze central strike. Jin for translation in case this is frequency lock tech."
Goh was already at the hub, scanning lower maintenance maps that flickered in and out through damaged circuits.
"The tube terminates in a regulator vault beneath secondary chamber. Old ecology used it for juvenile organism handling and quarantine."
"They built a nursery down there?" Marlen asked.
"A containment nursery," Goh said. "For things they didn't trust yet."
That tracked too well with Gael's methods.
Asha pointed to two troopers.
"You two on rear cover. If lane closes, you cut us out."
One of them was the rookie with patched chest armor. He nodded hard.
Raze looked at Goh.
"Come with us."
She shook her head.
"If I leave the hub, lower map dies and your path becomes guesswork."
"Then route us fast."
"I will." Her eyes locked on his. "And you will not overdraw in confined channels. If your glands seize down there, no one carries you back."
He wanted to promise something better than the truth.
He gave her the truth.
"I'll try."
---
The maintenance tube smelled like cold coins.
It was just wide enough for single-file descent, slick with condensation and lined with old regulator teeth that could shear flesh if you slipped. Yejun went first with one hand and a short blade. Mira second, knife low, silver eye scanning seams. Raze third. Jin fourth. Two troopers rear.
At the first branch, the left wall twitched.
Not living stone. Trap seam.
Yejun froze and touched two fingers to the panel edge.
"Pressure trigger," he said. "Weight threshold tuned under seventy kilos."
"For children," Jin said quietly.
Mira slid a mesh wedge into the seam and nodded.
"Trip it with dead weight after we pass. Might close route behind us and slow pursuers."
Raze pulled one dead vanguard arm from his pack, dropped it on the plate, and watched steel teeth slam out from both walls with enough force to puree bone. The teeth stayed extended for three seconds, then retracted.
"Useful," Yejun said.
At the second branch, they found fresh marks in anti-consumption lacquer: the same claim symbol Mira had shown earlier, now painted in thin lines that glowed faintly in the dark.
Mira touched the edge and hissed.
"New coat. Under an hour."
Yejun glanced back.
"Can we erase it?"
"Not fast. It's not paint. It's command varnish. Marks route ownership to network auxiliaries."
"Meaning everything in this tube thinks it has right-of-way."
"Exactly."
They moved faster.
Halfway down, voices started.
Not Gael's broad chamber projection this time. Whisper-close mimicry inside the narrow tube, one voice per person.
"Raze, she's already gone."
"Yejun, left panel now."
"Jin, he blames you for this."
"Mira, your old nest called you coward."
The tube amplified everything.
Jin slapped her own earpiece off and switched to floor taps against Raze's boot for communication. One tap go. Two stop. Three threat front. They moved in silence after that.
At the final descent lip, they found Sori's braid tied to a pipe clamp.
Not torn.
Tied in a loop with careful fingers.
Mira stared at it and said, "Clerk behavior. Collection marker."
Raze's jaw locked so hard pain shot into his temple.
"Then we collect back."
---
The regulator vault was a bowl of old steel and living stone.
Circular chamber, twenty meters across, with a central cradle suspended over a black fluid pit. Around it, six articulated restraint arms hung from a ring gantry like surgical tools waiting for a body.
Sori was in the cradle.
Strapped at wrists and ankles with soft loops that were not injuring her, just holding her still while a thin probe hovered over her sternum and sampled pulse rhythm.
She was crying without sound, face wet, eyes huge.
Three clerks ringed the cradle.
A fourth stood at the pit edge with both spindle arms sunk into a control panel, feeding command input into dormant systems.
Gael stood on the far side of the pit in his patched coat, hands behind his back like a lecturer waiting for class to settle.
"You came quickly," he said.
Yejun fired before speeches. Two rounds to center mass.
Gael blurred sideways. The rounds hit stone.
Mira was already moving for flank. Raze went straight down center.
Gael lifted one hand.
The pit erupted.
Black fluid rose in ribbons and hardened mid-air into lattice bars that slammed between Raze and the cradle, creating a three-layer cage in under a second.
"No," Gael said mildly. "You don't get straight lines anymore."
Yejun's blade took a clerk at the knee. Jin pulse-blasted a second clerk's spindle with a captured baton. One trooper dropped on entry with a spike through his throat. The rookie dragged him behind cover and kept firing, face white.
Raze hit the lattice with Devour and got static burn in return.
The bars were lined with anti-consumption lacquer and seed-resonance wash. Built to hold things like him.
Gael watched him test the cage and nodded.
"Old ecology knew better than your generation. They built nurseries for dangerous children."
He looked at Sori.
"She resonates cleanly with regulator channels. Better than most adults. Small systems adapt faster."
Raze slammed the lattice again.
"Touch her again and I eat your tongue."
Gael smiled.
"You misunderstand intent. I didn't take her to hurt her. I took her to make you pick correctly."
"Correctly for who?"
"For persistence."
Gael tapped the control ring with one finger. A map projection bloomed over the pit: corridor lines, node clusters, city overlays, red spread zones where power failures were expanding from district to district.
"Your room thinks this is a siege. It's a transition event. Legacy systems failing. New systems claiming right-of-way." His gaze shifted to Raze. "I can stabilize the transition with low mortality if you deliver the seed and stand beside me while I mark the chain."
Yejun laughed once, blood on his teeth.
"He says low mortality like he's offering tea."
Gael ignored him.
"Or you can keep pretending every city and every child survives. That fantasy is expensive. You are already paying with glands and friends."
Raze looked at Sori strapped in that cradle and felt something in him go very still.
"Open the cage," he said.
Gael tilted his head.
"No."
Goh's voice cracked through every comm channel at once.
"Raze, listen. Vault systems are tied to node root. I can force emergency juvenile-release protocol from the hub, but it requires direct seed immersion."
Jin's eyes widened.
"Immersion where?"
"In me," Goh said.
Silence in the vault for one beat.
Then everyone talked at once.
"No," Raze said.
"Alternative?" Goh snapped back. "You are inside a nursery cage built to hold aberrants. Gael's using legacy constraints plus lacquer. You don't brute-force that before he relocates the child."
Raze slammed a burst into the lattice and got nothing but a shower of sparks.
Goh continued, voice fast and clinical because panic wastes seconds.
"If I merge seed into my pathways, I can authenticate as bioregulator and command full juvenile release plus vault lockdown. It will route through my body as buffer because the hub's direct ports are damaged."
"You'll burn out," Jin said.
"Almost certainly."
"Then no."
"Jin." Goh's voice softened for one breath. "Leadership is not the same as surviving."
Raze hit his comm so hard the casing cracked.
"Goh, do not do this."
"You asked me to route you fast," she said. "I'm still routing."
On the far side, Gael's expression changed for the first time. Not fear. Interest sharpened into concern.
"Goh," he called, suddenly direct, dropping the little-eater theatrics. "If you immerse the seed, the node marks you substrate-side. You don't come back out whole."
"Good," Goh said. "Then maybe you'll stop trying to recruit me."
---
At the hub, Goh broke the seed socket lock and lifted the cracked core with both hands.
Jin heard her through open comm and cried out, but she was in the vault with no way to physically stop it.
Goh sat on the hub floor, set the seed against her sternum, and drove a substrate spike through both in one motion.
The chamber pulse went from sixty seconds to instant.
No interval. Just continuous hum.
In the vault below, the black pit flashed white.
Restraint arms around Sori folded away and the cradle dropped to floor level. The lattice cage around Raze retracted into the walls. Every clerk in the room seized, spindle arms locking as regulation flood overloaded their command varnish pathways.
Gael swore and moved for Sori.
Raze beat him by half a step.
Raze scooped Sori out of the cradle and threw her to Jin, who caught her and rolled behind cover. Yejun and Mira hit Gael together from opposite angles. Gael caught Yejun's knife arm and kicked Mira into the pit rail hard enough to dent steel.
Raze drove into Gael's back and they crashed into the control ring.
Devour met Devour again.
This time, with Goh's flood running through the network, Gael's pathways stuttered. Not weak. Interrupted. His smooth counters came in fragments. Raze used every fragment, gouging for joints, biting, elbowing, fighting ugly and close.
Gael headbutted him and split his eyebrow. Raze answered with a suppression spike through direct contact that charred skin from Gael's collarbone.
Gael snarled.
Not amused now.
The vault ceiling alarm changed tone.
"Lockdown in twenty seconds," Goh's voice said through every speaker in the chamber and every pipe in the vault. It sounded thinner already, stretched by static. "If you're in there, leave now."
"Come with us," Raze shouted.
No answer to that part.
Yejun grabbed the rookie by the vest and shoved him toward the tube. Mira limped after with one arm hanging and blood in her mouth. Jin carried Sori wrapped against her chest. Raze backed toward exit, still facing Gael.
Gael did not follow immediately.
He stood at the pit edge, skin smoking where regulation flood burned through old grafts, and looked up through layers of stone as if he could see Goh at the hub.
"You choose extinction with nicer language," he said quietly.
Goh's voice came once more, weaker, but still clear enough to cut.
"I choose children over theories."
The vault doors slammed.
Raze and the others made the tube seconds before blast shutters sealed behind them. Shockwaves chased them up the maintenance throat as one lockdown gate after another dropped into place, isolating lower channels and forcing everything not already in the main chamber into sealed pockets.
When they burst back into the junction, the hub was no longer a column.
It was a cocoon of white substrate growth wrapping a seated human shape at its center.
Goh's hands were fused into the interface up to the wrists.
Her eyes were open.
She looked at Raze once across the chamber full of people she had just saved.
He took one step toward her.
She shook her head.
He stopped.
The substrate growth rose another few centimeters around her ribs.
The chamber pulse stabilized at forty seconds.
Raze could not hear his own breathing.
Sori's father took his daughter from Jin with shaking hands and held her so tight she complained in a tiny voice and that complaint made half the room laugh and cry at the same time.
Raze didn't move.
Goh's mouth moved once.
The speakers carried it for her.
"Lead them, little builder."
