Chapter 1: When the Sky Split Open

The sky over Denver cracked at 2:17 a.m., and by 2:18 the dead were already useful.

Caleb Voss saw the first split while he was on the catwalk above Aisle Twelve, one gloved hand on the rail, the other balancing a clipboard he hadn’t needed in six years. The warehouse was all steel ribs, humming fluorescents, and the sour-clean smell of pallet wrap and refrigerated produce. Below him, forklifts blinked amber across polished concrete. Beyond the loading bay doors, the city slept under a hard, dry wind that carried the smell of dust from the plains.

Then the dark outside the skylights opened like a wound.

At first he thought it was lightning—some weird, silent strike crawling sideways through the clouds. Then the line widened. The stars vanished behind a sheet of black glass, and the glass began to glow from within, veins of orange fire cracking across it in branching fractures.

“Jesus Christ,” someone breathed over the radio.

Caleb stopped moving. The clipboard slipped against his thigh.

Another crack tore open the sky. Not in the clouds. In the sky itself.

The whole warehouse went quiet in a way he had only ever heard in the high country right before a fire crowned over a ridge and the forest realized, too late, that it was already dead.

Down on the floor, Marisol from receiving stood with a roll of shrink wrap dangling from one hand. She stared up, mouth parted, her dark braid hanging over one shoulder. Deke at the pallet jack swore and made a sign he probably hadn’t made since his grandmother dragged him to church.

“What is that?” Marisol whispered.

Caleb didn’t answer. He couldn’t.

The fracture in the sky widened. Something red moved behind it, not light, not fire—something vast and alive, turning slowly beyond the split like an eye opening in the dark.

The warehouse alarms began to scream.

Not the fire alarms. The security system. A shrill, panicked, overlapping howl that scattered the workers into motion. Radios crackled. Forklift brakes squealed. A pallet of boxed avocados tipped and burst, green fruit rolling across the floor like shrapnel.

Caleb found his voice. “Everybody off the floor! Move to the office. Now!”

He sounded calmer than he felt. He had spent enough years riding helicopters into smoke to know panic was contagious. So was command, if you wore it right.

Deke pointed at the skylights. “You see that? Tell me you see that.”

“I see it,” Caleb said. “I also see doors, so start using one.”

His eyes had already gone to the exits, the lines of sight, the high windows, the places where fire or people or both could kill them. Old habits. You never stopped mapping escape routes. It was how you stayed alive when the world went sideways.

He climbed down the ladder to the floor just as the first sirens began to rise from downtown, thin and distant and then suddenly everywhere. The lights overhead flickered once, twice, and a hiss like a thousand radio stations bleeding into each other whispered through the speakers.

Then the warehouse loading door at the far end slammed inward hard enough to bend the frame.

Something hit it again.

Not a truck. Not wind.

Something that wanted in.

“Lock it!” Caleb barked.

Deke stumbled for the control box. Marisol was already running, eyes wide, breathing too fast. People screamed from the office corridor. Someone dropped a stack of manifests and the papers burst across the concrete like white birds trying to escape.

The door buckled a third time and splinters of metal flew from the seam.

Then the overhead speakers clicked once and a voice spoke through the warehouse, distorted but clean enough to understand.

INTEGRATION INITIATED.

The voice was neither male nor female. Flat. Warm. Wrong.

Everyone froze. Even the thing at the loading door seemed to pause, as if listening.

PLANETARY ASSET: EARTH. POPULATION DENSITY: ACCEPTABLE. RESISTANCE LEVEL: LOW.

Caleb stared at the ceiling speakers. “What the hell is this?”

Marisol laughed once, a sharp, disbelieving sound. “Is this a drill? Did somebody hack the PA?”

Then the sky outside screamed.

Not thunder. Not a plane.

The crack overhead widened with a sound like all the windows in the world shattering at once, and a blast of heat rolled through the skylights. Shards of old glass rained onto the warehouse floor. Somewhere outside, something huge hit pavement hard enough to make the building shudder.

People started yelling over one another.

Caleb got a glimpse through the loading bay’s security glass as a fireball rolled across the far side of the street, blooming orange against the black skyline. Then he saw movement inside it—too many limbs, too much speed, a shape that hit the pavement running and sprang over a car like it weighed nothing.

The radio on his shoulder crackled.

“Caleb?” It was Tom, the night supervisor, voice thin and broken by static. “Downtown just went dark. We got reports of—”

A wet crunch. A scream. The radio filled with noise.

“Tom?” Caleb snapped. “Tom, report!”

Nothing but static and breathing. Something gargled close to the mic. Then the transmission cut out.

Marisol grabbed his sleeve. “Caleb, what is happening?”

He looked at her, then at the door, then back up at the fractured sky pouring orange light into the warehouse.

He had seen firestorms strip ridgelines to bone. He had watched a wall of flame move faster than a man could run and take everything with it. But this was different. This was not a fire. This was a decision.

He swallowed once, hard. “Get everyone into the break room. Barricade it. Stay away from windows.”

Deke barked a laugh that was half hysteria. “Barricade? With what?”

“With anything heavy enough to slow something down.”

Another slam shook the loading door. The frame groaned. Dust sifted from the rafters.

Not a drill.

That thought landed in Caleb’s chest like a stone.

He moved.

“Hey!” he shouted at the nearest cluster of workers. “Office! Move!”

People obeyed because they heard the edge in his voice. An older stock clerk grabbed Marisol’s arm and started dragging her toward the break room. Deke shoved his pallet jack sideways to block the aisle, then stared at the door like it might apologize.

The PA voice returned, layered now with a faint chiming beneath it, as if some invisible window had opened in the air.

CLASS SELECTION AVAILABLE.

Every person in the warehouse stopped again.

Words burned across the air in front of Caleb’s eyes.

Not projected. Not reflected. Just there.

Sharp white text hanging over the concrete like a curse made visible.

AWAKEN OR REMAIN UNRANKED.

UNRANKED UNITS FACE SYSTEMIC REMOVAL.

Someone sobbed. Someone else shouted, “What the fuck is a class?”

Caleb’s stomach went cold.

He had a field med course, wilderness fire training, five years with smokejumpers, and one long, ugly stretch after that doing whatever paid when the med board took his knees but not his appetite for punishment. None of that prepared him for glowing words in the air telling him the universe had become a game and he was already losing.

More text spilled across his vision.

AVAILABLE CLASS OPTIONS:

VANGUARD

HUNTER

SCRIVENER

VEILTOUCH

WARDEN

UNCLAIMED

The word WARDEN throbbed once, a dim ember among the others.

Then the loading door exploded inward.

A shape burst through the smoke and sparks—something low and black and fast, all joints and teeth and long hooked forelimbs. It landed on the concrete in a skid of shattered metal, lifted its head, and Caleb saw too many eyes glinting red along a skull that should have belonged to no animal on Earth.

Behind it, through the broken doorway, came more.

Screams detonated through the warehouse.

The first creature launched itself at Deke.

Caleb moved without thinking, grabbing the nearest thing in reach—a steel pruning hook used for breaking down crates—and swinging like he was cutting line through saplings. The hook caught the thing across the shoulder and glanced off hide hard as burned bark. It twisted with impossible speed, jaws snapping. Caleb slammed his forearm into its throat and drove his weight sideways, buying Deke a heartbeat.

Deke fell backward and the thing hit the concrete with a wet skid. Caleb felt its claws rake his thigh through the work pants, hot pain blooming.

He kicked it hard in the skull. Once. Twice.

On the third kick, its head split open with a crunch and black fluid fanned across the floor.

Something inside Caleb screamed to keep moving.

He turned—and saw another creature vault the conveyor line toward Marisol.

She raised her shrink wrap roll like a weapon because she had nothing else.

“Down!” Caleb shouted.

He threw himself across two stacks of boxed potatoes, hit the concrete, and caught the creature’s foreleg with both hands as it passed over him. The impact wrenched his shoulders. It smelled like wet ash and carrion, like something that had crawled out of a chimney and learned hunger in the dark. Its weight pinned him for half a second. Enough to see its mouth open in a ring of needle teeth.

Then the loading dock’s emergency light swung down and struck it in the eye. The monster shrieked, and Caleb drove the steel hook up under its jaw until the point came out through the back of its skull.

The creature collapsed on him, all dead heat and bone.

Caleb shoved it off and rolled onto his knees, coughing against the smell.

Everything was noise now. The warehouse had become a panic chamber of alarms, screams, smashing glass, and the wet impact of bodies hitting the ground. People ran and fell and ran again. The office door slammed shut. Someone was beating on it from inside, sobbing for help. The monsters moved like a pack of knives in the smoke.

And the sky kept breaking.

Through the high windows, Caleb saw downtown Denver lit in pulses of orange and blue as explosions ripped across the skyline. A tower a few miles away sagged sideways in a spiral of fire. Something enormous moved between buildings, its silhouette wrong against the burning glass overhead.
