The station entrance was a concrete maw at the bottom of a short flight of stairs, leaking the smell of ozone and old dampness into the night air. Toby brought the SUV in hard and stopped at the curb.
He looked at the dash. "Hannah's signal pinged the turnstiles six minutes ago. They should have been at the surface by now."
Nobody answered that. The answer was self-evident.
Liam was already moving. He kicked the rear hatch open, boots hitting the asphalt, and hauled the M134 from the equipment rack in one practiced motion. The multi-barrel assembly was not a subtle weapon. He settled into position behind the open door, the motor giving its low predatory hum as the barrels began their idle rotation, and pointed his eyes at the rooflines.
"Nobody touches this car." He said it once, to the street.
Behind him, Kit had not moved from Sol's side. One hand checking the pulse at the throat, the other running a secondary check at the wrist. His expression said the hands would stay occupied until further notice.
Lucius scanned the stairwell entrance. The darkness below it was total — the station's emergency lighting had either failed or been cut. The silence coming up from the stairs was the wrong kind of silence, too complete, the kind that meant the noise had already finished rather than not yet started.
He looked at Miguel.
"Low heat only," he said. "You cause a ceiling collapse, I'm leaving you under it."
Miguel's palms were already running amber at the knuckles. "Surgical. Got it."
Lucius went down first.
---
The platform was three levels deep and the fluorescent strips overhead were doing their best. Most of them were losing.
He came off the last stair and read the scene in a single pass.
Further down the tunnel — away from the entrance stairs, pushed back into the darker stretch where the platform narrowed — Kira held a position in the center of the tracks. The carbide lattice dome was up around Hannah and Charlotte, the violet corona of it flickering at the edges under sustained load. Hannah had her back against the tunnel wall behind the maintenance cart, watching the dome's surface with the expression of someone reading a fight through a window. Charlotte stood between Hannah and the barrier wall, weapon drawn, covering the angle Kira could not both watch and defend.
Outside the dome, two figures were working the structure methodically.
The Anvil was the closer one. He was broad across the chest and shoulders in the way that suggested the material he was made of was simply denser than what most people were working with. His skin carried that dull heavy quality under the failing lights. He was hitting the barrier with his fists at a measured pace — not frustrated, not in a hurry. Each impact produced a sound like a bank vault being stress-tested. He had the patience of someone who had been told the thing would eventually fail and had decided to be there when it did.
The Warden stood further back, both palms pressed downward toward the floor, concentration locked. The effect had no light to it, no sound. Just weight arriving on Kira's dome from above — the carbide dust being pushed inward, the structure compressing under a load that came from nowhere and had no ceiling.
Kira's dust was thinning. The dome was going to crack.
Lucius moved.
He used the dead section of overhead lighting to cover the last ten metres, coming out of the dark at the end of the platform without a sound. The Warden's concentration was entirely on the dome. He was watching the barrier, tracking the compression, not the tunnel behind him.
The roundhouse caught him at the side of the head with the full rotation behind it.
The Warden left the floor. He hit the concrete support pillar at the platform edge hard enough to crack the tile, slid down it, and stayed — disoriented, not finished, but the gravity field collapsed the instant his concentration broke.
The dome stopped compressing.
Miguel hit the bottom stair at a run and arrived on the platform half a second behind the impact.
He read The Anvil and committed without breaking stride — both fists blazing, right hook coming in at jaw height with full bio-thermal charge behind it.
The Anvil took it.
His head barely moved. The detonation lit the tunnel in orange for a moment and something came out of him that was not pain. Lower than that. More like satisfaction.
His hand shot out and caught Miguel's leg at the knee.
He spun on his heel and threw him through the turnstile row at the platform entrance. Miguel hit the tiled wall on the far side and the wall gave, taking the impact in a shallow depression, before he dropped to the floor.
Lucius was already closing.
He drove a punch into The Anvil's ribs. The impact rang back through his knuckles like hitting structural material — the physiology flaring under the strike, the tissue behind it growing denser as the force landed. He could feel the adaptation happening. Like hitting something that was learning.
The Anvil reached for him.
Lucius went under both arms, weaving low, feet moving, circling to the figure's left side. The Anvil was a big man — genuinely big, the kind of frame that made most approaches a problem. Lucius used that. He planted a boot on the shoulder joint, drove off it, and got up — locking his legs around the neck from behind, thighs tight against the jaw line, ankles crossed in front. High enough that the grab attempts would find nothing but air below him.
He started working the back of the skull.
Short, fast, targeted. The skull was dense but the brain behind it was the same material as everyone else's. The goal was not to break through. The goal was to rattle what was inside the casing until the casing became irrelevant.
"Kira." He kept his eyes on the movement of The Anvil's hands, watching for the angle that was going to change. "Drop it. Move. Toby's waiting at the surface."
The violet corona behind him began to dissolve. The carbide lattice came down.
Kira's voice was completely level. "Four minutes since signal loss. For the record."
He had already turned. Charlotte steered Hannah deeper into the tunnel, away from the fight, weapon up and covering the passage behind them. Kira moved ahead of both, hands out of his pockets.
Then the weight returned.
The Warden had dragged himself off the pillar. He was upright, blood on his temple, both palms pressing down. The gravity field landed across the full center of the platform — Lucius felt it hit his shoulders, felt the increased load through the legs locked at The Anvil's neck. The tiles beneath The Anvil's boots cracked and sank.
"Target reacquired," The Warden said. "Increasing pressure."
The Anvil's hands found Lucius's ankles.
Miguel was back.
He came up from the turnstile wreckage with a fistful of charged debris — tile fragments, a section of handrail, loose gravel, all of it blazing — and threw it directly at The Warden's face. The detonations hit in sequence, each one forcing a flinch and a step back, the concentration fracturing before it could build the field to full load.
The weight stuttered.
Lucius released the neck lock, planted both hands on The Anvil's upper back, and dropped — pushing clear of the grab as both of the figure's hands came up where his legs had been. He landed in a crouch and came up moving.
The Anvil turned to face him. He rolled his neck. The ledger of every strike landed on him so far was written nowhere on his expression.
"Not bad," he said, in the tone of a man making a genuine assessment. "Hit me harder next time."
He stepped forward.
Across the platform Miguel was keeping The Warden moving — charged fragment after charged fragment, forcing the concentration to break and reset before the gravity field could rebuild. The Warden was bleeding and recalibrating, his voice dropping instructions to himself in the flat tone of someone managing a suppression operation.
Lucius looked down the tunnel. Hannah and the others were gone — further in, moving. The platform was clear.
He looked up. Original station structure above him, concrete and rebar, maybe four metres. Running the full length of the platform.
He looked at Miguel. Miguel was mid-throw, another piece of charged debris leaving his hand toward The Warden.
The Anvil swung.
Lucius went under the swing, inside the reach, and hit the figure three times fast — each strike absorbed, each one noted and filed by the physiology as data rather than damage. The third one produced a slight stagger.
"Miguel." He said it flat, not loud, and the moment the name was out he was already moving — two steps across the platform, catching Miguel by the back of his vest mid-turn, using the momentum they both had, and sending him straight up toward the ceiling.
Not away from the fight. Into it, upward, while The Warden was still reacquiring and The Anvil was still recovering his footing.
Miguel read it in the air. He twisted, both palms coming up, and hit the ceiling flat-handed at the top of the throw — the bio-thermal cells transferring into the concrete in a dense cluster, burning orange against the grey, pulsing with the unstable charge of something that had not yet decided its timing.
He came back down and landed beside Lucius.
"Go," Lucius said. "Down the tunnel. Stay with them — we don't know what else is out there."
"I'm not—"
"Miguel."
One second. Miguel held it, his fists still simmering with frustrated heat, then turned and ran... fading into the tunnel.
Lucius turned back to the fight.
The Warden had both palms up again, the ceiling charge visible above them, the gravity field pressing down on it, warping the space around the cluster of loaded cells. The Anvil had stopped moving. He was watching with an expression that had shifted — something in it recalculating.
Three seconds after Miguel's footsteps left the platform, the ceiling came down.
The detonation in the enclosed space was total — a single overwhelming percussion that shook the walls, cracked the support columns on both sides of the entrance, and brought the full section of concrete and rebar down in one mass. The entrance archway disappeared under it. The exit disappeared under it. The dust that came off the collapse filled the platform in a wall and then slowly began to settle.
When it did, the tunnel was sealed.
The platform was a sealed room now. Flickering lights. Three people in it.
The Warden looked at the rubble. Then at Lucius. The grim set of his face had not changed but the silence he occupied had.
"You just buried yourself" he said.
Lucius rolled his right shoulder. Then his left. He reached up, cracked his neck once on each side, and looked at both of them across the settling dust.
"I didn't bury myself," he said.
The overhead lights flickered once.
"I locked you in with me."
