The Cull Protocol
The travel from confrontation ground to climax arena consumed the next hour. Headlights cut cold through the gathering dusk.
The trigger sat under Owen’s thumb. Owen’s voice echoed across the bridge: “I built this ark to survive the ashes. You can’t stop the new world.”
Xavier Ashby measured the route to the command terminal for what felt like the hundredth time. Twelve meters. Two guards. Between Xavier and the array sat a palm-reader that had already rejected him three times in his life, and would reject him again. The worm rode the flex-strip coiled around his wrist, three terabytes of decryption and hijack code waiting for a port. He needed the machine. Owen needed to stop being able to breathe.
Owen’s thumb came down.
The detonator clicked. For one breathless fraction, Xavier thought the whole thing had been theater, a bluff folded into a threat. Then the klaxons rolled up from the lower decks like a rising tide, a low animal sound that rattled the bulkhead panels and drowned out the bridge’s ambient hum. The war-display above Owen’s head switched from a constellation map to a city schematic. Red indicators bloomed in a cascading line down the Ark’s spine—a row of dominoes toppling outward into the districts. Air scrubbers. Forty-three of them. Offline.
On the camera feed, District Nine’s streetlights were already drowning in an amber haze that rolled through the canyons like floodwater.
“Cull Protocol,” Owen said, holding the trigger up like a trophy. “I gave the lower districts air fine enough for a hospital. Now I’ve shut it off. Four minutes until the exhaust reaches lethal concentration.” He tucked the trigger into his coat pocket. “You can save them, Xavier. You have the means. The only question is whether you’ll reach it before I feed you to the hull.”
Xavier shifted his weight, feeling the flex-strip’s cold edge press into his skin. He subvocalized, throat barely moving. “Dorian. The hatch.”
“I’ve got it.” Dorian’s voice came back clipped and quiet, over the rumble of the alarms. “Two on the bridge. One at the access van. Kill the lights when I say.”
The guard nearest Owen raised a sidearm. Owen made a small, dismissive gesture with two fingers, and the guard’s posture sharpened.
“Kill him,” Owen said.
The guard fired. Xavier launched sideways, rolling behind a data console as the round sang off its stamp-edged frame. Dorian’s suppressed shot answered from the maintenance hatch, clipping the guard’s shoulder, spinning him into the railing. The second guard swung his rifle toward the muzzle flash, and Dorian was already moving—low, fast, boots eating the deck in three strides before he slammed a forearm into the man’s throat. The rifle clattered. The guard crumpled.
Xavier came up off the deck, feeding the flex-strip’s connector into the emergency service socket at the terminal’s base. The terminal blanked. Then a single phrase blinked white on black: UPLOAD IN PROGRESS.
Owen saw it. His face shifted from command to something rawer, and he lunged across the bridge with a speed that belied his age. Xavier took a shoulder to the ribs, his chin cracking against the console lip. His teeth caught the inside of his cheek, and copper flooded his mouth. His grip never left the strip.
“Dorian!”
A forearm came down across Owen’s collarbone like a beam. The old man hit the deck with a breathless wheeze, and Dorian’s knee pinned his spine while practiced hands stripped the detonator from his pocket and sent it skittering into the corner of the bridge.
“Seconds on scrubbers?” Xavier asked, eyes locked on the progress bar.
“Three minutes, maybe less.” Dorian’s weight held Owen flat against the deck plating. “Stand down,” he said to the old man, a command with no patience left in it.
The bar hit one hundred. The terminal went black, then rebooted in a blur of green text as the worm tore through the Ark’s command architecture like a vote of no confidence. The war-display blinked, stuttered, and rewrote itself.
Every drone in the launch bays flipped to active status, flight paths reversed, safeties engaged, targeting priorities rewritten. A second program screamed through the city utility grid, and on the schematic, the red indicators flipped green in a rippling wave that moved faster than the alarm could track. The camera feed showed District Nine’s haze beginning to thin over the rooftops, streetlights emerging from the murk like lanterns on a shoreline.
“Cull Protocol terminated,” Xavier said, finding his feet. He tasted blood, wiped his mouth with the back of his hand. “Scrubbers are back online. The drone fleet now flies for the city. Your purge failed.”
Owen laughed into the deck plating. A thin, wet sound. “You think the city matters to me? Ashby, the Ark is in pre-launch.” He craned his neck, grinning through the pain of Dorian’s knee. “Eight minutes. The vessel leaves with or without me. And anyone still onboard is going to be very dead in a very expensive way.”
Xavier pulled up the security grid. A single Ravenwood signature streaked through the forward spine, moving fast, heading for an access hatch into the utility galleries. Flynn. Running.
“Dorian. Flynn’s heading for the forward access hatch. If he seals those tunnels, he rides the launch clean.”
Dorian met his eyes, and something passed between them—a wordless understanding that needed no airtime. He released Owen, leaving him winded on the deck, and moved toward the hatch with the long, flat stride of a man who had done this work before. He was gone into the spine’s green emergency light before the echoes of his footsteps faded.
Xavier keyed his comm. “Cassidy. Cargo override. Everything between Pod Bay Twelve and Airlock Seventeen. Open it all.”
Her voice came back, low and controlled. “Already on it. He’s moving.”
—
The control booth smelled of stale coffee, ozone, and burnt wiring. Cassidy Prescott had wedged herself into the operator’s chair, knees pulled up, hands moving over a terminal that had been dead until she’d jammed a stolen Ravenwood service key into its access port. Pod Bay Twelve spread out beyond the reinforced glass: a row of utility capsules, each the size of a sideways coffin, each sealed with a pressure latch and a red indicator light.
Pod Four. Inside, Max.
He sat cross-legged on the pod’s floor, the green jacket wrapped around his shoulders like armor. His face was pale, but his eyes were dry, fixed on the porthole as if he could will her to appear. He had stopped crying. That was worse than crying.
Xavier’s voice crackled in her ear. “Cull is dead. Worm is live. I need the whole corridor cleared to Airlock Seventeen.”
Cassidy didn’t answer with words. Her fingers swept across the terminal, green indicators snapping on in sequence as pod bay doors rolled open, interior bulkheads slid aside, and the entire corridor network between her and the airlock opened in a chain reaction. A map on the console lit up with a single green dashed line tracing the route.
She pressed the intercom button. “Max.”
A pause. Then his voice, small and careful. “Yeah.”
“I need you to stand up, open the pod door, and run toward the green lights on the floor. They’ll lead you all the way to the end. Do you understand?”
“Are you coming?”
Her chest tightened. “I’m right behind you. I’ll meet you there. You run, Max. You don’t stop for anything.”
The pod door slid open with a hiss. Max stepped out onto the staging platform, looked right, looked left, then broke into a run, following the green guide lights. His small footsteps echoed through the speaker in the control booth.
Cassidy pushed out of the booth and took the service stairwell, skipping steps, the metal rails cold under her palm. Her legs burned. The corridor rang with the distant boom of launch clamps releasing. She hit the landing, turned, and ran the parallel service route that would intersect Max at the airlock.
—
Dorian came through the forward spine’s access hatch already braced for the blade. Flynn Ravenwood was young, desperate, and cornered; men like Flynn didn’t throw punches when they had a utility gallery of shadows to use. The knife flashed out of the dark in a wide arc, aimed at Dorian’s throat.
Dorian didn’t step back. He stepped inside the arc, caught the wrist, drove it into the bulkhead frame until the blade rang loose, and followed through with a palm strike that snapped Flynn’s head back. The heir crumpled, and Dorian knelt over him, running a mag-cuff around his wrists.
The man was awake, but barely. Dorian dragged him upright. “Owen’s secure. Flynn’s in custody,” he said into his comm. “I’m taking the shuttle off the flight deck. Don’t leave without me.”
“Count on it.” Xavier’s voice, static-roughened. “We’ll be on the platform.”
Dorian hauled Flynn toward the shaft lift, already mapping his path to the shuttle bay, already done with this place.

Xavier dropped out of the maintenance grate and hit the corridor floor with a jolt that went up through his knees. He straightened, tasting blood from his split lip, and looked down the long white corridor toward Airlock Seventeen. The inner pressure door stood open, the outer door sealed, the airlock chamber lit in cold amber.
A small figure burst around the far corner.
Max skidded to a stop, sneakers sliding on the polished deck. He stared at Xavier through a shock of dark hair, his face working through a series of expressions too fast to name—fear, hope, disbelief—and then his eyes wet, and his chin crumpled.
Xavier opened his arms.
Max crossed the distance like a launched projectile and slammed into him. Xavier folded around the boy, one hand rising to hold the back of his head, the other arm locking around his ribs. Max’s breath came in shivers against his collarbone, small, broken sounds muffled into his jacket.
“It’s okay,” Xavier said. “I’ve got you. It’s okay.”
Footsteps. Two pairs, one running, one walking.
Cassidy rounded the corner at a dead sprint, saw them, and stopped so abruptly she almost tipped forward. Her hair had come loose, her jacket torn at the collar, a smudge of engine grease across her cheek. She looked at Xavier, at Max, at the way they held each other, and her face did something complicated before she crossed the distance and folded herself around them both.
Max gave a small, ragged sob and buried his face in her shoulder. Xavier’s hand found the curve of Cassidy’s jaw, tilting her face up. Their foreheads touched.
“Hey,” he said, voice frayed at the edges.
“Hey,” she breathed back.
For a moment, the only sound was the vast hum of the Ark, the distant klaxons, and three people breathing the same recycled air.
Then a shudder ran through the deck plates, followed by a dull, resonant boom that echoed up through the corridor like a struck bell. Launch clamps. Releasing.
Xavier looked past the airlock’s window. On the docking platform beyond, the city lights flickered back to full brightness across the lower districts. The haze was nearly gone. The drone fleet hung in orderly patrol patterns over the skyline, running his worm’s signature, obeying his commands.
He looked down at Max. “We’re leaving. All of us. Together.”
Cassidy took his hand and squeezed. “Together.”
The airlock’s inner door began to cycle shut. The outer door slid open onto the platform, letting in the night air—cold, wet with rain, carrying the sharp clean smell of ozone.
They crossed the threshold as a unit, Max between them, his small fingers wrapped around both of theirs. Behind them, the Genesis Ark’s running lights flickered as the automated launch sequence moved into its final phase. The platform vibrated under their feet.
A cold automated voice filled the deck: “Genesis Ark departure in five minutes. All unauthorized personnel will be left behind.”
