Ty cut through the nearest tendril, and the blade shook in his hand.
The sound that came out of it was too soft for the room. It did not sound like metal striking ice. It sounded like a throat trying to work through water, and then the sound was gone. Ty kept the blade moving.
Another tendril snapped in from his left. He turned his shoulder, let it pass close enough to scrape cloth, and cut through the pale root behind it. Black fire ran along the edge and bit deeper than steel should have been able to bite.
The cut pieces fell into the acid and boiled away.
His fingers barely closed around the grip. Cold had turned them slow. Every swing started in his shoulder now, not his hand, and the blade dragged his balance forward if he missed by even a little. A bad swing would put him in the acid before the tendrils needed to touch him.
The pits across the floor had widened while he fought. What had been separate holes now touched in crooked lines. Acid spread under plates of ice, ate upward, and broke the floor from beneath. The safe path kept changing.
Ty backed onto a strip of white stone no wider than his boot.
The door showed itself when a sheet of ice slid from the far wall. Dark wood. Black frame. A lock set at chest height. Ty had his line.
He ran before the room took the line away.
A tendril whipped across his ankles. Ty jumped, landed badly, and felt something tear along his thigh. He kept moving. His bag caught on a jagged ridge of ice and yanked him half around, then the strap broke.
Everything inside spilled across the floor. Wrapped supplies, small tools, old cord, the wristband he had kept because throwing anything away felt stupid in this place. The acid reached the nearest bundle and chewed through the cloth. Ty looked once and saw the wristband slide toward green liquid, half of it already smoking, then he turned back to the door.
He hit it shoulder first hard enough to numb his arm. The wood held. He dropped to one knee, dumped the keys into his palm, and forced the first one into the lock. It broke before it turned.
The second key scraped the mouth of the lock and refused to enter. The third went in too easily, loose enough to rattle. The fourth turned a little and froze there, stuck deep, its end bending under his hand.
Ty snapped it off and dug the broken piece free with the point of his blade.
The acid had reached the scattered keys. He grabbed three before the rest went under. His fingers burned where green drops touched skin. He wiped them against his coat and shoved another key into the lock, but the metal stopped halfway in.
The door did not shift. The lock gave him nothing. Behind him, tendrils dragged themselves out of the acid with new color under the white, green showing through the frost like rot under skin.
Ty set his shoulder against the door and worked the next key in with both hands, and something struck his side.
The blow drove him into the frame. Air left his chest. His teeth cut the inside of his mouth, and blood ran over his tongue. He spat without looking and brought the blade down where the tendril had wrapped his coat.
It pulled away before the edge touched it. Ty caught the movement for what it was. The tendril had pulled back from the blade before the cut landed, not from pain but because it recognized danger.
The next tendril came for his wrist instead of his chest. It knocked the key loose and flung it into the acid. The last key sat in his palm, bent and useless before he even tried it. Ty stared at the lock and understood the shape of the attack. Every strike had aimed him away from the door. Every time he reached for the lock, the tendrils hit his hands. When he shifted toward the center of the chamber, the nearest ones tightened but held their angle. The door was being guarded.
The drones moved above him, their lenses finding his face, his hand, the broken keys at his feet.
In the viewing room, JJ leaned over the table until one of the attendants stepped back from her.
"Stop staring at the door and watch the center."
Her voice could not reach him. The broadcast kept it for everyone else.
Alexander’s father lifted his glass and watched Ty’s feed with the look of a man judging a bad investment.
"That boy keeps surviving by ruining everyone else’s math."
On another screen, Gisorn had climbed onto a hanging chain while spiders gathered below him in dark layers. Kern stood in a circle of snakes, cutting space with careful steps that grew smaller each time the ring tightened. Their trials had their own clocks. Their own crowds. Their own people deciding when fear became entertainment.
Ty had no space left for any of them when the tendrils came together.
One struck low and took his legs from under him. Another caught his waist before he landed. The coil tightened, lifted, and threw him upward. The ceiling rushed close.
Ty twisted before impact and took it with his shoulder. Pain flashed down his arm. The tendril holding his waist dragged him sideways and slammed him against a hanging rib of ice, then another, then spun him out over the broken floor.
He cut once. The blade carved the coil apart, but three more caught him before he fell. One wrapped his forearm. One pinned his ankle. One crossed his chest and squeezed until his lungs fought for room.
The green color spread through them while they held him. They had learned his reach.
Ty stopped trying to swing wide. The blade was too long in that grip, and his arm had no strength left for clean cuts. He drew his elbow close to his ribs and sawed down through the tendril at his wrist. The thing jerked away from the edge again, showing him fear, or orders that looked like fear. Ty let his hand go slack.
The tendril around his chest tightened at once, believing the surrender, or accepting the shape of it. Ty curled around the pressure and pulled black fire into his fist instead of the blade.
Heat crawled over his knuckles. It hurt worse than the cold because it woke every cut the ice had made. He held it anyway.
The tendrils dragged him lower, toward the open acid. The liquid below snapped and spat against broken ice. Heat pushed through his boots before he touched it.
Ty looked past the door. The center column stood in the middle of the room, half hidden by moving roots. Every tendril crossed back toward it between attacks. The ones he cut did not die where they fell. They retreated, reformed, and came back from that same point. The lock was the part he could touch, but the column was where the room kept beginning.
Ty drove his burning fist into the tendril across his chest.
Black fire burst along the coil and ran through the others touching it. The pressure broke at once. He dropped, spun, and cut the ankle coil before it could drag him sideways again.
For one ugly stretch of air, he had no floor under him.
He saw the acid below. He saw the door beyond it. He saw the column drawing the tendrils back into shape.
Ty twisted his hips and threw the blade point down. The edge caught a raised crack in the stone, skipped, and slowed him enough that his boots hit the last solid patch instead of the acid.
His knees folded, and pain ran up both legs. He bit down and forced himself upright with the blade as a crutch.
The tendrils gathered around the center column. White frost steamed off them. Green acid moved beneath their skin now, pulsing with every new coil that formed.
The clock above the door showed two minutes. Ty wiped blood from his mouth with the back of his wrist. The door and the lock were still there, but the thing holding both shut was in the center.
Ty shifted his grip on the blade and turned away from the door.
