The lights in the barracks snapped to full white at 0555, stabbing straight into Kael's skull like hot wires. No alarm. Just the sudden glare and the clank of the overhead strips powering on. His body jerked awake on the thin mattress, every muscle already knotted from the night before. The gray jumpsuit clung to him, soaked through with cold sweat that smelled sour and metallic. His tongue was glued to the roof of his mouth, still tasting the burnt-plastic sedative from the skiff and the chalky residue of last night's protein brick.
"On your feet, recruits," a filtered voice barked from the corridor speaker. "Medical induction. You have three minutes."
Kael rolled off the bunk. His bare feet hit the cold composite floor and the chill shot up his legs like glass shards. The boy beside him—a skinny kid with a fresh bruise blooming across one cheek—landed hard and immediately doubled over, dry-heaving into the trough. Nothing came up but thin yellow strings of bile that splattered and stank of stomach acid and fear. The girl with the split lip from the skiff was already standing, arms wrapped tight around her ribs, eyes fixed on the floor like it might swallow her.
They filed out in the same ragged line, forty-two kids now—more had arrived overnight in silent shuttles. No one spoke. The only sounds were bare feet slapping composite and the occasional wet cough. The corridor air was colder than yesterday, recycled so hard it tasted like breathing through steel wool. Kael's stomach twisted, but there was nothing in it to throw up.
The medical bay doors hissed open and the smell hit first: antiseptic so thick it burned the sinuses, layered under with the copper tang of old blood that the scrubbers could never quite erase, and something sweeter, like rotting meat left too long in a sealed locker. Overhead lights blazed merciless white, turning every surface into a mirror of pain. The examination tables had been unfolded overnight—forty-two of them in precise rows, each with thick padded restraints at wrists, ankles, and forehead. Overhead scanner arms hung like chrome spiders, needles already extended and glistening under the glare. IV poles stood ready, clear bags of fluid swaying gently.
"Strip and mount," the lead medic ordered. She was the same masked woman from processing, voice flat as a combat knife. Two soldiers in ghost armor flanked the doors, carbines low but ready. "Face up. Arms out. Do not fight the restraints or we will sedate you unconscious. You will feel everything either way."
Kael's hands shook as he peeled off the jumpsuit. The fabric stuck to his damp skin with a wet ripping sound. Naked again, the air clawed at him—freezing across his narrow chest, his belly, the backs of his thighs. Gooseflesh erupted so hard his teeth chattered. He climbed onto the table. The padded surface was ice-cold and slightly tacky, like it had been wiped down but not dried. The restraint pads clamped shut around his wrists with a hydraulic *snick*, then his ankles, then a wide band across his forehead that pinned his head back so he could only stare at the blinding ceiling. The table tilted thirty degrees, lifting his torso. Blood rushed to his head.
Beside him, the boy who had vomited was already strapped down and crying openly, snot bubbling from his nose. "I want my mom," he whimpered. "Please, I want my mom."
The medic didn't even glance at him. She moved down the line with a rolling cart of syringes—long, thick ones with glowing blue fluid, shorter ones with oily green, and one set of hair-thin neural injectors that looked like silver spiders. "Batch one, full spectrum," she called to her assistants. "Growth hormone cascade, myostatin inhibitors, neural plasticity enhancers, and the proprietary marrow accelerant. Start with the youngest. They take it hardest."
Kael's table was third in line. He watched the first kid—a tiny girl no older than five—get the needles. The medic swabbed her arm with something that smelled like burning alcohol. Three separate punctures: one in the crook of the elbow, one at the base of the neck, one straight into the spine between the shoulder blades. The girl screamed the moment the first plunger went down. It wasn't a child's cry. It was the sound of something being torn open from the inside.
Kael felt his own pulse hammer in his ears.
Then it was his turn.
The medic's gloved fingers were cold and efficient. She swabbed the inside of his left elbow; the alcohol evaporated instantly, leaving a freezing patch. The first needle slid in—thick, cold metal parting skin with a wet pop. Kael sucked in a breath through his teeth. The plunger depressed.
Fire.
It started as a bloom of heat in the vein, then exploded outward like someone had poured molten glass straight into his bloodstream. The heat raced up his arm, across his shoulder, down his chest. His back arched against the restraints so hard the pads creaked. A guttural sound tore out of him—half scream, half animal grunt. The second needle went into his neck. This one burned colder, like liquid nitrogen chased by acid. It hit his spine and his whole body convulsed once, legs jerking against the ankle straps, heels drumming the table. The taste of copper flooded his mouth; he'd bitten his tongue.
The third needle—marrow accelerant—went straight into the crest of his hip bone. The medic had to lean her weight on it. Kael heard the wet crunch as it punched through cartilage and into the soft red core. Pain detonated like a grenade inside his skeleton. Every bone in his body lit up at once—grinding, stretching, cracking louder than the screams around him. He felt his femurs lengthen, the marrow inside boiling and reforming. His ribs creaked outward, cartilage popping like bubble wrap. His spine elongated with a series of wet clicks that he felt in his teeth.
He screamed until his throat tore raw. The sound joined the chorus—forty-two children shrieking in perfect, overlapping agony. One boy two tables over started vomiting mid-scream; the restraints kept his head back so the bile ran down his cheeks and into his hair. Another kid's monitor flatlined for three seconds before the medics shocked him back. The smell of piss and shit and vomit thickened the air until Kael gagged on it.
Time lost meaning. The fire in his veins kept building, wave after wave. Sweat poured off him in sheets, soaking the table beneath his back, dripping onto the floor with soft patters. His vision tunneled to white-hot pinpricks. He saw his mother's face for a second—her auburn hair matted with blood on the kitchen floor—and then it was gone, burned away by the next surge.
The medic's voice floated somewhere above him, clinical and bored. "Subject 647 responding well. Vitals elevated but stable. Bone density increasing twelve percent already. Neural uptake at ninety-four. Keep the saline wide open—he's cooking."
Kael's jaw locked so tight he tasted blood again. His fingers clawed at nothing, nails digging crescents into his own palms. The restraints creaked. Somewhere in the bay a girl was begging, "Make it stop, make it stop, please God make it stop," over and over until her voice cracked into a wet gurgle and she went silent. Kael didn't know if she was dead or just unconscious. He didn't care. All he cared about was the fire trying to split his skeleton apart from the inside.
Hours passed. Or minutes. The overhead lights never dimmed. The medics moved between tables like butchers at a slaughter line, checking monitors, injecting counter-agents when a kid started seizing, wheeling the ones who flatlined out on gurneys that left red smears on the floor.
Finally the last plunger emptied. The needles withdrew with soft sucking sounds, leaving tiny wells of blood that the medics sealed with spray-on skin. Kael's body kept burning. The pain didn't stop when the needles left—it settled deeper, into the marrow, into the spaces between his vertebrae, into the roots of his teeth. Every heartbeat sent fresh lava through him.
They unstrapped him eventually. His limbs wouldn't work right. Two soldiers had to drag him off the table. His bare feet slapped into a puddle of someone else's vomit and the slick warmth made him retch again. The gray jumpsuit they shoved back on him felt like sandpaper on raw nerves. They marched—or carried—the survivors back to the barracks. Eight kids didn't make it out under their own power. Two were already in body bags outside the bay doors, the black plastic gleaming wet under the corridor lights.
In the barracks the lights were dimmed to sullen red again. Kael crawled into his middle bunk on hands and knees, every joint screaming. The thin mattress was already damp with his own sweat from the night before. He curled on his side, knees to chest, arms wrapped around his ribs like he could hold the fire inside. The rock around him thrummed with the base's hidden machinery—pumps, generators, the distant whine of a fast-spooling hyperdrive somewhere far above.
All around him, the other kids were sobbing. Not loud anymore. Just broken, hopeless sounds—wet hitches of breath, muffled whimpers into thin pillows, the occasional sharp cry when a muscle spasm hit. The girl across from him rocked back and forth, forehead pressed to the wall, whispering "mommy mommy mommy" until her voice gave out.
Kael pressed his face into the mattress and bit down on the fabric to keep from screaming again. The taste was stale detergent and his own tears. His bones still felt like they were growing, stretching, cracking millimeter by millimeter. The fire had banked to a dull roar, but it never went out.
He thought of the dunes on Calyx-7. The wind. His father's laugh. His mother's hand ruffling his hair. All of it gone, replaced by this black cradle of rock and needles and the cold blue eyes of General Marcus Rael.
Somewhere in the dark, a boy started coughing blood. The wet, rhythmic sound went on for a long time before it stopped.
Kael closed his eyes. The pain followed him down into a shallow, fevered sleep, and the sobs of forty children echoed off the stone like a promise of more to come.
