The Blackthorn Algorithm Protocols

The Genesis Fault

The travel from The Canopy Substation, industrial district to Blackthorn Mainframe Core, underground substation level B2 consumed the next hour. Headlights cut cold through the gathering dusk.

The world had become a tunnel of static and pain. Lucas’s fingers scraped against the concrete floor, the tablet’s shattered glass digging into his palm as he fought to stay conscious. Above him, Grant’s polished Oxfords clicked a slow circle, the sound amplified through the ringing in Lucas’s ears.

“You know,” Grant said, his voice drifting through layers of distortion, “my father always said you were the smart one. The one who got away.” A pause. Somewhere, water dripped from a pipe. “But smart men still bleed.”

Lucas’s hand found the edge of his father’s tech vest. The fabric was worn, the stitching frayed from decades of storage, but the weight was still there. A small cylinder, no larger than a roll of quarters, sewn into the interior pocket. His father had called it an insurance policy. A last resort from the days when Blackthorn still built hardware that could be turned against them.

EMP. Mark 3. Single-use. Fifteen-second charge time.

Grant’s shadow fell across him. “Selene sent her little packet of secrets. Cute. But federal agents are still thirty minutes out, and by the time they get here, this facility will be scrubbed clean.” He crouched down, and Lucas could smell the expensive cologne, could see the manicured fingernails holding a sleek black pistol. “And you’ll be a tragic accident. A father who couldn’t let go of the past.”

Finn. Lucas’s fingers found the cylinder’s activation switch.

“The boy goes first,” Grant said. “I think that’s appropriate, don’t you? Payback for the trouble your wife has caused. The algorithm needs a final sacrifice to—”

Lucas thumbed the switch.

The vest hummed. Electricity crawled up his arm, a deep bass vibration that shook his teeth. Fifteen seconds. He had fifteen seconds.

“What are you—?”

Lucas rolled, grabbing Grant’s ankle, pulling the man off balance. The gun fired. The round punched into the floor inches from Lucas’s skull, concrete chips slicing his cheek. Grant stumbled, cursing, and Lucas used the momentum to push himself upright.

The substation was a cathedral of industrial decay. Steel catwalks crossed overhead, massive generators humming in the corners, coolant pipes snaking along the walls. A drone—sleek, matte black, one of Blackthorn’s new patrol models—buzzed through the air twenty feet above, its targeting lens tracking Lucas’s movement.

Ten seconds.

“Kill him!” Grant screamed, scrambling backward. “Kill them all!”

The drone’s weapon systems whirred to life. A red targeting dot painted Lucas’s chest.

Seven seconds.

Lucas dove behind a coolant tank. The drone fired—three rounds, rapid, tearing through the tank’s exterior. High-pressure steam erupted in a violent cloud, scalding his arms, filling the air with a deafening hiss. He couldn’t see. Couldn’t breathe. The heat was a wall.

Five seconds.

Somewhere, Finn was crying. The sound cut through the chaos like a blade.

Three seconds.

Lucas pressed his back against the tank, the vest’s core now glowing orange through the fabric. His teeth chattered. His vision flickered. The drone’s targeting reticle reappeared through the steam, locking onto his position.

One second.

Zero.

The EMP discharged.

There was no explosion. No flash of light. Just a wave of pressure that knocked the air from his lungs and a sound like a million dying televisions. Every light in the substation went dark. The drone dropped from the air, a dead weight, crashing into a control panel with a shower of sparks.

The generators choked, coughed, and died.

Absolute silence. Then the emergency lights flickered on, weak and amber, casting long shadows across the wreckage.

Lucas’s ears were ringing. His hands were shaking. But he was alive.

“Lucas!” Beckett’s voice, strained, over the comms. “The building’s losing power. Structural integrity is—shit, get out of there, the whole substation is going to—”

A groan of metal. A support beam above them, weakened by the drone’s fire, buckled.

Lucas saw it in slow motion: the beam twisting, snapping free of its moorings, falling directly toward the catwalk where Beckett was taking cover.

“BECKETT!”

The security chief looked up. He had exactly enough time to swear. Then the beam hit, a ton of steel and concrete, slamming him to the ground. Dust exploded outward. The catwalk collapsed in a chain reaction, sections falling like dominoes, burying him.

No. No, no, no.

Lucas stumbled toward the rubble, but another beam groaned above him. The ceiling was destabilizing. He had seconds.

“Lucas.” Aurora’s voice, sharp and clear, cutting through his panic. “The server room. The north ventilation shaft. The blueprints showed a junction box three meters in. I can reach the core from there.”

“Aurora, the ceiling is—”

“I know. But I can do this. You get Finn. You get out.”

He wanted to argue. Every instinct screamed at him to protect her, to drag her out of this hellhole. But she was already gone, her footsteps echoing through the comms, growing distant.

The blueprint. He’d shown it to her the night before, tracing the old ventilation routes with his finger. She’d memorized it. Of course she had.

Lucas turned and ran.

He found Finn in a storage alcove, pressed against the wall, his small hands covering his ears. The boy’s eyes were wide, wet with tears, but he wasn’t screaming. He was waiting. Trusting.

“Daddy.”

“I’ve got you.” Lucas scooped him up, the boy’s weight familiar and grounding. “I’ve got you, buddy. We’re leaving now.”

He ran. The emergency lights flickered, casting strobing shadows as he navigated the chaos of the substation. Pipes burst overhead, drenching him in freezing water. Sparks rained from exposed wiring. The building was dying around them, and he had to be faster.

Aurora crawled through the ventilation shaft, the metal grating cutting into her palms. The blueprints were burned into her memory—every turn, every junction, every weakness in the Blackthorn infrastructure. Her father-in-law, Lucas’s father, had designed this facility. He’d built it with a paranoid’s attention to detail, including the access routes that no one else remembered.

She reached the junction box. Three meters in, just like the schematics promised.

The server room was visible through a grate below her. A cathedral of data, rows upon rows of server racks, their indicator lights glowing like stars in the emergency darkness. The algorithm’s master files were stored in a central node, a black monolith at the room’s heart.

She pulled the access panel open. Wires. Hundreds of them. And there, nestled among them, the primary cable. Thick as her wrist, armored, running directly from the node to the building’s emergency generator.

The failsafe.

Lucas’s father had installed it during the initial construction, a dead man’s switch that could wipe the entire system if the facility was compromised. He’d never told Silas. Never told anyone except his son, who had written the location in the margins of his old blueprint.

Aurora pulled the safety pin.

The cable hummed. The lights in the server room flickered, then steadied.

She had sixty seconds.

Lucas burst through the substation’s emergency exit, Finn pressed against his chest, the cold night air hitting his lungs like a shock. They were outside. They were alive.

The building behind them groaned, a sound like a dying animal. Windows shattered. Light poured from the cracks.

“Lucas.” Selene’s voice over the comms, trembling but steady. “The federal agents are here. They’re moving in. I sent them everything—the papers, the accounts, the transfer logs. Silas and Grant are done.”

He turned. In the distance, sirens. Red and blue lights cutting through the dark.

“And Aurora?” he asked.

“She’s still inside.”

The server room erupted.

Aurora had never heard a sound like it. A roar of electrical fury, the scream of failing hardware, the crackle of data burning into nothing. The servers flickered, one by one, their lights dying as the purge cascaded through the system.

The algorithm was dying.

She should have felt triumphant. Instead, she felt only the desperate need to survive.

The ventilation shaft shuddered around her. The building was collapsing. She crawled backward, the metal grating hot against her skin, the air thick with smoke.

“Aurora!” Lucas’s voice, tinny through the comms. “Where are you?”

“South exit. Two hundred meters. I’m coming.”

She dropped from the shaft, landing hard on the concrete, her ankle twisting. She ignored the pain. Ran. The hallway was filled with smoke, the emergency lights barely piercing the haze. She followed the turns, counting steps, trusting her memory.

The door. It had to be here.

Her hand found the handle. She pushed.

Fresh air. Stars. And Lucas, standing thirty meters away, Finn in his arms, his face illuminated by the fire consuming the Blackthorn building.

She ran to him.

Behind them, the building’s western facade collapsed inward, a roar of dust and flame that shook the ground. Federal agents swarmed the perimeter, their vehicles forming a ring of light. Two men were being led out in handcuffs. Silas Blackthorn, his silver hair disheveled, his face a mask of cold fury. And Grant, his suit torn, blood running from a cut above his eye, his composure shattered.

Selene stood beside one of the federal vehicles, a tablet in her hands. She met Aurora’s eyes across the chaos and nodded.

It was over.

Lucas pulled Aurora into his arms, Finn between them, the three of them holding each other as the server room exploded in sparks. Aurora screamed over the comms. Lucas pulled Finn into his arms and whispered: “It’s over. We’re free.”
