The Decay System: I Alone Can Reinforce Reality

The train was seven minutes late, and Silas Vance had already decided to hate himself for it.

He stood pressed against the doors of the Line 4 express, forehead almost touching the glass, watching the tunnel lights smear past like dying stars. His phone buzzed against his hip for the third time in ten minutes. He did not need to look. It was the hospital. It had been the hospital all week.

"The surgery has been moved up to tonight, Mr. Vance," the nurse had told him that morning. "If you want to see your sister before she goes in, come early."

Early. He had been stuck in a site inspection until six, because the firm had hinted that leaving would cost him his contract, and the contract was paying for Mira's treatment. Now it was 7:42. Her surgery was at eight.

He checked the time again. Seven minutes had become eight.

Eleven years ago, Silas had missed his father's last breath because of a deadline. He had stood at the grave afterward, twenty years old and hollow, and made himself one promise: never again. Never be the one who arrived too late.

The train lurched. Somewhere behind him, a toddler began to cry.

Silas closed his eyes. Come on. Come on. Just forty more minutes, Mira. Hold on for me.

The lights went out.

For one heartbeat, there was only the screech of brakes and the shuddering groan of metal. Then the emergency lamps flickered on, pale and green, and Silas heard a sound he had never heard in twelve years of inspecting buildings.

It was the sound of steel forgetting how to be steel.

A dry, whispering hiss ran along the ceiling of the car. Fine gray powder drifted down like snow. A woman beside him touched the handrail, and the handrail came apart in her fingers, crumbling into grit.

"What is that?" she whispered. "What is happening?"

Then the screaming started.

The seats dissolved first. People fell through them as if the cushions had never existed. The windows turned milky and slumped inward. The floor under the far end of the car simply stopped being a floor, and eleven people dropped into a darkness that did not echo.

Silas grabbed the nearest vertical pole. It was cracking under his palm, flaking into dust, and in a stupid, clear, professional flash he thought: structural failure at the molecular level, impossible, this is impossible.

His hand clenched.

And the pole stopped dying.

A pale gold light bled out from under his fingers and ran up the metal like water climbing a wick. The cracks sealed. The flaking stopped. Around his grip, a circle of floor about the size of a small bathroom hardened and held while everything beyond it kept collapsing.

Then words burned across his vision.

[DECAY SYSTEM INITIALIZED.] [Molecular binding energy of this world: reduced by 94 percent.] [Scanning survivors for compatible host.] [One candidate found.] [Unique class unlocked: Architect of Reality.]

Silas stared at them. His heart hammered so hard it hurt.

"Mister!"

A small voice, close to his knee. A girl of maybe six, red backpack on her shoulders, standing at the very edge of his circle with her toes over the line. Beyond her feet, the floor was already gone. Her mother was nowhere in sight.

The girl's shoe began to crumble.

Silas did not think. He lunged, caught her wrist, and dragged her inside the golden ring. Her sneaker finished dissolving into powder on the other side of the line. She was shaking so hard her teeth clicked.

"Don't let go," he said. "Whatever happens, don't let go of me."

She nodded. She did not let go.

Around them the train fell apart. The roof peeled away like burnt paper, and the tunnel walls flaked into a storm of gray. Silas poured everything he had into the one thing he could do, willing the world around his hands to hold. His head pounded. Something inside his chest was draining out of him, thin and cold, with every second the circle stayed solid.

[Stability: 31 of 31.] [Reinforcement consumes 1 Stability per second per square meter.] [Warning: current radius cannot be maintained indefinitely.]

He understood what that meant. Thirty seconds. Perhaps less.

"Up," he told the girl, and lifted her onto his shoulders. "Hold my head. Do not look down."

The tunnel ahead was a wall of falling dust, but far above, a sliver of dull orange light showed through the collapse. A stairwell, still half-standing. Silas ran. He ran the way he had never run in his life, and wherever his foot landed, the ground turned solid for exactly one step before it dissolved behind him. Stability ticked down. Twenty. Fifteen. Nine.

He burst up the broken staircase and out into the street just as his count reached two.

He collapsed to his knees on a slab of pavement that was still, somehow, pavement. The girl slid down from his shoulders and clung to his coat. Silas gasped in air that tasted of stone and ash, and looked up.

The city was dying.

Not exploding. Not burning. Dying slowly, in silence, the way a sandcastle dies when the tide takes it. Skyscrapers shed their glass in glittering sheets, and their steel skeletons bent and powdered and folded into themselves. Cars dissolved on the road. People ran, and some of them stopped being people halfway through the run. A gray haze rose over everything, thick and shining, and it fell back down as gentle, endless dust.

And on the hill to the east, three kilometers away, stood St. Aurelia Hospital, its upper floors already fading into the sky.

Silas's phone rang.

His hands shook as he dragged it from his pocket. The screen was cracked and flickering, but the name on it was clear.

MIRA.

He answered. "Mira?"

Static. Then, thin and very far away, her voice. "Silas? Something is wrong. The walls, they are..." A crack of sound like a distant avalanche. "Silas, I am scared. Where are you? Please come. Please."

"I am coming," he said. "I promise. I am coming right now."

The line went dead.

New words rose in front of his eyes, cold and calm and merciless.

[Target detected: St. Aurelia Hospital. Distance: 3.2 kilometers.] [Current Stability: 0 of 31.] [Recovery rate: 1 per minute.] [Estimated time until hospital dissolution: 4 minutes.]

Silas looked at the hill. He looked at the little girl whose fingers were knotted in his coat, whose mother was gone, whose shoe was gone, whose whole world was gray powder drifting into the dark.

The ground under the edge of the pavement began to crumble toward them both.

One minute of Stability. That was all he would have. Enough to save one thing. One person.

[Reinforce target? Choose before decay reaches host.]

His sister, or the child.

The dust reached his shoes, and Silas Vance, who had promised himself he would never be too late again, had three seconds to decide.
