Public Proof

Ren crossed the entry line with twelve minutes left before the seasonal lock and a drain in his ribs that made each breath feel borrowed. The Obsidian frame rode his back like a second spine. It was still missing the interface core that should have made it legal, stable, and expensive. Instead, the chassis was using him for that function, drawing on his life force through the bonded mount while the illegal fuel cell in its belly thrummed with a resonance any audit scanner could smell.

The proving ground went quiet when the telemetry board lit up.

OBSIDIAN-LADDER FINAL TRIAL REGISTERED CONSTRUCT: INCOMPLETE INTERFACE CORE: ABSENT TRACE SIGNATURE: PRESENT OPERATOR: REN VEY RISK STATUS: EXTREME

A few students had expected him to crawl in on a repair sled. Instead they got a frame built like a rumor and a pilot who looked half starved.

Maelin Arct rose from the upper platform before the first hazard gate opened. Her trial coat was immaculate, her ringlight badge catching the arena glare like polished coin.

“That machine is not eligible,” she said, voice clear enough to carry to the far stands. “It is missing a certified core, the fuel signature is flagged, and the operator is already under network scrutiny from the Internal Audit Board. If this is allowed, the ladder stops meaning anything.”

Ren kept his eyes on the floor strip ahead of him. The drain in his chest sharpened every time the frame adjusted around his balance. He could feel the buried handshake in the mount, that hidden hook in the metal waiting for power so it could register him through the Academy’s own lattice. The machine was a debt he wore.

“It means exactly what it always has,” Instructor Halden Wren said from the dais. He did not raise his voice. He did not need to. “Whoever can make the machine answer under the rules earns the rank. Whoever cannot does not.”

Maelin’s jaw tightened. “You are overriding a technical disqualification.”

“I am recognizing a functional one.” Wren finally looked up from his ledger. His gaze moved from the frame to Ren, then back to the live board. “If you want mercy, Arct, submit a donation request. This is a trial.”

The first gate split open.

A wall of pressure hit the arena floor, followed by three lance pylons rising from the deck in a staggered line. Their fields were tuned to force unstable frames into a stall. The standard pattern was designed for pilots with clean cores and healthy reserves. Ren had neither.

He stepped forward anyway.

The frame took the first surge and nearly buckled. Pain flashed white behind his eyes as the bond drank from him to fill the missing interface core. He caught the collapse by pushing more of his own qi through the Circuit-Breaker channel, cutting the safety governor off before the frame could hesitate. The move hurt. It always hurt. But the frame answered.

A visible readout flashed across the board.

OUTPUT: 41%.

That number was low enough to mock him and high enough to matter. He had gone from unusable to functioning in one breath.

The second pylon fired.

Ren drove the frame low, letting the hazard arc scrape the shoulder plating instead of the cockpit line. The illegal fuel cell took the shock and converted it into a hard, hungry pulse through the limbs. The chassis lurched forward with enough force to crack the deck seam underfoot. A few students in the lower rows actually stood up.

“Stable?” someone muttered.

“No core,” another voice said back, thin with disbelief.

Ren didn’t answer. He couldn’t spare breath on surprise. The frame was still using his life force as the bridge, and the bridge was costing him. He felt it in the ache behind his sternum, in the slight tremor that moved down his forearms every time the machine shifted weight. But the drain was not random. It was measurable. The more output the frame gave him, the more the board ticked upward.

OUTPUT: 56%.

Maelin saw it too. Her expression changed only by a degree, but it was enough. She had expected a stunt. What she was watching was a conversion rate.

“That cannot hold,” she said, though the words had sharpened less like certainty and more like prayer.

Wren’s fingers tapped once against the edge of his ledger. “Nothing holds. The question is whether it buys enough time to matter.”

Ren crossed the first lane in a blur of black plating and white hazard light. He hit the third pylon with the frame’s left shoulder, redirected the recoil through his hips, and used the bounce to drive into the central ring before the field could reset. The motion was ugly, efficient, and personal. It was not the polished ballet the academy sold in its recruitment reels. It was debt turned into momentum.

The board changed again.

OUTPUT: 63%. LADDER POSITION: MOVING

That was the first real gain. Not theory. Not potential. A number everyone in the arena could read.

The hazard cycle escalated. Four drone rigs unfolded from the ceiling tracks and dropped into the airspace above the ring. Their beams targeted weak points in the frame’s unsealed joints, trying to pry the chassis apart around the bond.

Ren felt the attack through the mount like pressure on a cracked tooth.

He snapped the Circuit-Breaker technique through the frame’s safety mesh. The governors died. The frame surged.

The cost hit at once. Heat flashed through his core. His vision narrowed. For one ugly instant he thought the bond might tear him apart from the inside.

Instead, the frame answered with something cleaner than speed: control.

The Obsidian chassis pivoted under him with a precision that had not been there before. The missing core should have made it sluggish, compensating, always half a beat late. The buried handshake in the mount rewrote that weakness into access. The frame borrowed from the Academy lattice itself—routing load through Ren’s life force, then back into the machine as if the two of them were one registered system.

He saw the lanes.

Not in a mystical sense. In the practical, brutal sense of pressure vectors, power draw, and field timing. He could tell where the drones would aim before they committed. He could tell which plates would take another hit and which would shear.

Ren drove straight through the first drone’s targeting cone. The beam missed by a handspan. His right arm came up in a short, hard strike, and the frame’s forearm edge clipped the drone cleanly in half.

A second drone dropped low.

He let it think he was lagging, then used the fuel cell’s surge to step sideways so fast the impact beam burned empty floor. The frame’s heel hooked the drone’s strut. It spun, crashed, and burst in a shower of sparking shards.

The crowd noise changed after that. Not cheers. Not yet. Something more dangerous to Maelin: attention.

Ren kept moving. Three more drones. Two hazard walls. One counterburst from the floor emitters that should have stalled a clean pilot and would have broken a weak one.

He took the hit on purpose.

The frame slid back two meters, plated boots carving grooves in the deck. Pain punched through his ribs, and for a second the bond screamed so hard he tasted blood. But the impact loaded the chassis like a spring. He turned the recoil into a forward launch and smashed through the last drone ring before it could tighten.

OUTPUT: 79% PENALTY: LIFE-FORCE DRAIN HIGH TRACE ALERT: PENDING

There it was. The measurable cost.

Ren’s jaw locked. He could feel the warning in his bones now, a constant pull that made the frame less like armor and more like a creditor with hands around his throat. If he kept pushing at this rate, the drain would leave him shaky for hours. Maybe longer. If the Audit Board chose to look closely, they would have numbers to work with.

Maelin didn’t miss the alert. Her voice sharpened. “He is bleeding through the bond. Halt the trial before he corrupts the registry feed.”

Wren answered without looking away from the board. “If he corrupts it, you may file a complaint.”

“That is not a reply.”

“It is the one you have.”

The final sequence opened with a vertical pressure cage, six beams crossing in a narrowing hex. The room around it dimmed. The arena wanted a clean finish. It wanted him pinned, drained, and obvious.

Ren stepped into the cage anyway.

For three heartbeats nothing moved.

Then the beams snapped inward.

He let the frame absorb the first two and split the third with a shoulder roll that should not have been possible in a chassis this incomplete. The hidden handshake flashed once through the mount, and the Academy lattice answered with a brief, illicit pulse of routing access. He caught a sliver of the proving-ground control logic and used it against the cage itself, forcing one emitter to overfeed and the opposite side to lag.

The gap opened.

Ren went through it.

He came out on the far side with the frame’s forearm raised and the Circuit-Breaker load burning red across his nerve map. One strike. That was all the trial asked for now. One decisive hit.

He planted the frame’s left foot, let the fuel cell dump a final hard burst into the limbs, and drove the right hand into the central pylon at the heart of the arena.

The impact sounded less like metal breaking than a vault seal giving way.

The pylon collapsed. The hazard grid died. The drone lights went dark one by one across the ceiling.

A flat, clean tone rang out from the audit board.

TOP OF TIER. RANK CONFIRMED. PUBLIC PROOF ACCEPTED.

For a heartbeat the whole arena forgot how to breathe.

Then the gate behind the dais began to open.

It was not a normal access door. It was a vault aperture, thick as a loading wall and cut in the old academy style, all black ribbing and sealed seams. Cold air spilled from it in a slow, expensive draft. The smell that came with it was oil, metal, and something older than either—stored power, kept under lock too long.

The Inner Sanctum.

It opened wider than Ren expected, wider than the stands had any right to know about. Inside was not a chamber for gifted students. It was a production floor dressed like a shrine. Rows of stripped frames stood on rails beneath white lamps, their mounts exposed, their cores removed, their fuel lines tagged for reuse. Some were elite models. Some were older. All of them looked processed.

Ren understood the shape of the place in one glance.

The Academy did not just rank students. It refined them.

A projected window snapped into the air above the threshold.

INNER SANCTUM SCHOLARSHIP OFFER ELIGIBILITY: OBSIDIAN RANK CONDITION: VOLUNTARY ACCEPTANCE BENEFIT: CORE ACCESS / ADVANCED ROUTING / FUNDED MAINTENANCE CLAUSE: TECHNIQUE REVIEW REQUIRED

Technique review. A polite way to say harvest what works.

Ren stared at the offer while his heart hammered against the bond. The drain was still there, still measuring him, still making every second of rest expensive. He had reached the top of the current ladder, but the ladder had not ended. It had simply turned into a cleaner, better-lit machine.

Maelin had gone pale with fury. Not because he had won. Because the next room had recognized him.

Wren closed his ledger and finally stood. “You have the standing to enter,” he said to Ren. “You also have the standing to be very profitable.”

It was the closest thing to encouragement Ren had ever heard from him.

He looked from the offer to the stripped frames beyond it, then back to the board still flashing his rank. The numbers were real. So was the trap.

His hands trembled once. Not from fear. From the cost of holding the frame together.

He had climbed high enough to see the next floor.

And the next floor was already waiting to buy him.
