The fever broke by morning, but the fire in Kael's bones never really left. It just learned to hide.
He woke on the barracks bunk with his gray jumpsuit plastered to his skin, the fabric stiff with dried sweat and the faint metallic crust of blood from his nose. The rock around him still thrummed—deep, patient, the heartbeat of the Obsidian Veil buried under kilometers of nickel-iron. Forty kids had gone into the needle bay yesterday. Thirty-eight crawled out. Two small black bags had been wheeled past in the night, the wheels leaving faint red smears on the composite floor that the scrubbers hadn't quite erased. The smell lingered: bleach, shit, and the sweet-rot of failing bodies.
"Up," the filtered voice barked from the speaker. "Ring time. You have two minutes."
Kael's legs shook as he dropped from the middle bunk. His bare feet hit the cold floor and the chill stabbed up through his calves, but something was different. The grinding ache in his hips was still there, but his stride felt… longer. Stronger. Like his skeleton had stretched overnight and decided to stay that way. He filed out with the others, the line thinner, quieter. The girl with the split lip—her name was Lira, he'd learned in a whisper—walked beside him, her face pale, lips pressed tight. No one spoke. Speaking got you a hypospray to the neck.
The training ring was a wide circular chamber carved from the asteroid, fifty meters across, walls lined with the same hexagonal cloaking mesh that shimmered when you looked too long. Overhead strips cast harsh white light that left no shadows. The floor was padded composite, already scarred with old bloodstains that no amount of hosing could lift. Racks of training gear waited: padded batons, weighted gloves, low barriers for crawling. At the far end, a line of obstacle dummies stood like silent enemies—some with reactive stun-fields, others with hidden blades for the "real" drills.
General Marcus Rael waited at the center, arms crossed, scar livid under the lights. His steel-grey eyes swept the line once.
"Basic kinetics," he said, gravel voice flat. "You hit. You get hit. You learn or you break. The Republic doesn't waste resources on the slow. Move."
The first drill was hand-to-hand.
They paired off by height. Kael got the older boy from the skiff—the one who'd vomited on the ramp. The kid was eight, already taller, with mean eyes and knuckles scarred from something back on his own fringe world. No pads. No helmets. Just bare fists.
"Begin," the instructor called.
The boy swung first. A wild haymaker that Kael barely ducked. The punch whistled past his ear, close enough he felt the wind. Kael's own punch came on instinct—small fist cracking into the boy's ribs. The impact jarred up his arm, but the new strength in his bones made it solid. The older kid grunted, eyes widening in surprise, then drove a knee into Kael's stomach.
Pain bloomed hot and deep. Kael doubled over, tasting bile and the copper of his own blood where he'd bitten his tongue. The floor rushed up. He hit it hard, cheek scraping the composite, the grit of old sweat and dried blood grinding into his skin. The older boy laughed once—short, ugly—then stomped down. Kael rolled at the last second. The boot cracked the floor beside his head.
"Again," the instructor snapped.
They fought for twenty minutes. Kael took three more hits that split his lip and swelled his left eye shut. Blood ran down his chin, warm and salty, dripping onto the gray jumpsuit. But he landed two solid ones himself—one to the jaw that made the older kid's head snap back with a wet click, another to the solar plexus that dropped him gasping. By the end they were both on their knees, chests heaving, the air thick with the iron stink of blood and the sharp ozone of sweat.
Nova's voice slid into his head like warm silk, only for him. (Not bad, big guy. But in the manga, the hero waits for the villain to overcommit. Watch the eyes. They always telegraph.) Her laugh was soft, quirky. (Chapter two tonight. The hero gets his first real scar. You'll like it.)
Kael didn't answer. Couldn't. But the words stayed with him.
The injections came again that night.
Four more needles—this time into the thighs, the shoulders, straight into the spine while he was strapped face-down on the table. The marrow accelerant burned hotter the second time. He screamed until his throat tore raw, the sound joining the chorus of thirty-eight other voices. One boy seized so hard his restraints snapped; the medics shocked him twice before wheeling him out in a bag. The smell of charred skin and urine filled the bay.
By week three the training had begun to blur.
Obstacle courses at dawn. Crawling under razor-wire that nicked his elbows and knees, the cuts stinging with antiseptic spray. Climbing sheer walls with only finger-holds, arms burning, sweat dripping into his eyes until they blurred. Running sprints through corridors where the lights flickered to simulate strobe grenades—disorienting, nauseating. Kael's legs lengthened week by week, the swimmer's build starting to etch itself under the gray fabric: lean cords of muscle over lengthening bones, shoulders broadening just enough to make the jumpsuit pull tight across his back.
Kids kept dying.
One girl—nine years old, fast but fragile—hit a live stun-field during a night drill. The crack of electricity lit the ring blue-white. She jerked once, spine arching so hard Kael heard vertebrae pop, then dropped smoking. The medics didn't even bother with the gurney; they dragged her out by the ankles, heels leaving twin red trails.
Another boy, the one who'd cried for his mom on the first day, failed the third injection round. His bones tried to grow too fast. Kael watched from the next table as the kid's legs bowed outward with wet, grinding sounds, skin splitting like overripe fruit. Blood and marrow leaked onto the floor in thick, dark ropes. The screaming lasted six minutes before they silenced him with a final needle to the base of the skull. The bag they zipped him into was too small.
"Waste," Rael muttered once, watching another body pass. "But the strong ones are worth it."
Kael learned to run faster. To hit harder. To vanish when the instructors' eyes weren't on him—ducking into the hexagonal cloaking mesh along the walls, letting the adaptive fields swallow him for three, four heartbeats before the sergeants dragged him out by the collar.
Nova was always there in the quiet moments, her voice a secret warmth against the cold rock.
(Faster, champion. In Blade of the Forgotten, the hero dodges the spear by a hair. You just beat that record.) She read him snippets every night in the dark of the bunk—harem tales of betrayed boys who rose, claimed their peace, found women who waited with soft curves and selfless hearts. Once, during a rare five-minute break between drills, she appeared in his mind's eye on the edge of the ring, silver hair drifting, robes shimmering over those inviting curves. (Look at you growing. That swimmer's frame is going to look good on a hero. Keep breathing. The needles get worse before they get better)
He did. Month after month.
By age eight the pain had become background static. His body was changing faster now—six inches taller, lean muscle wrapping his frame like steel cable under skin. The other kids noticed. A loose pack of survivors formed around him: Lira, quieter now, her split lip healed into a thin white scar; a boy named Jax from a mining world, missing three fingers from a failed blade drill but mean with a baton; and a small girl called Mira-2 (they reused names when originals died) who could disappear into shadows better than any of them.
Rivalries sharpened too.
A bigger kid—ten already, broad and vicious, called Torv—decided Kael was a threat. During a paired spar, Torv waited until the instructor's back was turned, then drove an elbow into Kael's kidney with everything he had. The pain was a white-hot spike, like someone had jammed a live wire into his spine. Kael dropped, gasping, tasting blood. Torv leaned in close, breath hot and sour.
"Fringe rat," he hissed. "You'll break before I do."
Kael came up swinging. His fist caught Torv under the chin with a crack that split the older boy's lip wide open. Blood sprayed across Kael's knuckles, warm and slick. They went down in a tangle, fists and elbows and knees, the padded floor turning wet and red beneath them. The instructor finally pulled them apart, but not before Kael had a fresh black eye and Torv was missing a tooth.
Nova chuckled in his head afterward, wings flexing like blades. *That's my champion. In the stories, the bully always gets the scar first. Chapter's getting good.*
The injections continued every ten days. Each round hurt worse, but Kael's body adapted. Bones lengthened without shattering now. Muscles knit faster. The medics started noting "exceptional uptake" on his chart. Rael watched him closer, those cold blue eyes narrowing with something like approval.
By age ten, the ring felt smaller. Kael moved through the obstacle course like liquid shadow—vaulting barriers, sliding under wire, striking the reactive dummies with precise, brutal efficiency. His knuckles were permanently split and callused. Scars crisscrossed his forearms and shins, thin white lines against the lean muscle that was filling out his frame. The gray jumpsuit hung looser on his broadening shoulders, tighter across the chest.
Thirty-eight had become nineteen.
The bodies kept rolling out at night—sometimes two, sometimes four. The smell of the bags followed them into the barracks: plastic and death and the faint ozone of whatever the medics used to keep the decay down. No funerals. No words. Just the quiet zip of black vinyl and the squeak of wheels on composite.
One night, after a drill that left Jax with a broken arm and Lira coughing blood from a cracked rib, Kael lay in his bunk staring at the rock above him. The thrum of the base vibrated through his lengthening spine.
Nova appeared in his mind, sitting cross-legged at the foot of the bunk, silver hair glowing soft, robes draped over those full, graceful curves. She held up an imaginary manga page.
"Next chapter's the big one, big guy," she whispered, voice quirky and warm. "The hero loses his last friend… but he keeps going. Because the women are waiting. The peace is waiting. You're going to get there. I'll make sure of it."
Kael's small, scarred hand clenched the thin blanket. The fire in his bones had settled into a low, constant burn—fuel now, not just pain.
Outside the ring, the galaxy turned. The Vanguard drilled their iron legions on distant worlds. The Lumina hoarded their patents. The Helios counted credits. The Elyrians prayed for purity. The Mermer Republic sharpened its invisible blades in the dark.
And in the Black Cradle, a six-year-old boy who had once clutched a toy starship was becoming something else.
Something the war would fear.
