They found him under the staircase two days later.
FEDRA soldiers in full hazmat gear swept the dead zone in a slow line, rifles up, calling out in flat, tired voices. One of them caught the shape of him in a crack between two slabs of fallen concrete — a boy, curled tight, filthy, breathing. They dragged him blinking into the grey daylight. Dust had worked so deep into his lungs that his first breaths came out as coughing, and his leg throbbed with every heartbeat, a dull, constant ache. The wound on his calf had scabbed over by then into an ugly, crusted gash — the kind of thing rubble did to a person, nothing more.
He said nothing. He let them carry him.
He was processed in a sterile clinic that smelled of bleach and cold metal. They stripped his forest-worn clothes off him and scrubbed him until his skin felt raw and new. A doctor with tired eyes prodded at the scabbed calf, glanced at it, and moved on — far more interested in his ribs, which stood out like a xylophone, and the hollowed cheeks, the grey pallor of a starving child. They gave him a cup of water and a ration bar, and then they filed him: another orphan, another lucky one pulled out of the wreckage. He was assigned to a different section of the QZ, further from the ravaged inner zones, and that was that.
The new section wasn't a city so much as a fortress. Layers of reinforced concrete, barbed wire strung like grey lace, checkpoints with their barriers painted in chipped yellow. The air was cleaner than the ruins, but it still tasted of concrete dust and stale sweat, with the faint, sour tang of fear underneath it all.
The noise was the worst of it. Bells marking the hours. The endless shuffle of boots on concrete. Gates clanging. Radios crackling somewhere out of sight. It was a cacophony that grated on everything in him — he had grown up inside the quiet symphony of the forest, where every sound meant something. He missed the smell of pine. He missed the silence that held its own stories. Here the noise was just noise. Overwhelming. Draining.
They put him in a communal dormitory: a vast, echoing room of metal cots packed so close he could hear the breathing of the boy beside him. At night the other children cried in their sleep, small muffled sounds in the dark, and some of them huddled together in fearful knots, finding what comfort they could in shared terror.
Ethan kept to himself. He observed.
He watched the children squabble over broken toys, saw the desperate hunger flare in their eyes at mealtimes, noted how their shoulders hunched and their voices dropped whenever a FEDRA officer walked past. He saw all of it — the vulnerability, the rawness — and felt himself pull further inward, the way a hand pulls back from a hot stove. He couldn't afford to be weak.
FEDRA ran everything by bell and routine: wake-up, assembly, work detail, meal, curfew. There was no corner of the QZ truly unwatched. Ethan swept barracks, sorted salvaged supplies, carried messages between checkpoints, and he did it all with an efficiency that made him quietly invaluable. He never complained. He finished before the others had properly started, and moved on to the next thing.
Sorting salvage was where it showed most. He'd sit with a pile of broken tools and his small hands would just know — this one stripped for parts, this one dead, this one worth keeping — separating them with a practiced ease he couldn't have explained. Once, turning a faulty circuit board over in his fingers, he felt something flicker behind his eyes: a ghost of schematics, logic gates, current flows, gone before he could catch it. An echo of something he didn't understand yet. But his hands understood. They always had.
He watched the soldiers the way he'd once watched deer. He learned the patrol routes around the perimeter walls — not just the paths, but the exact minute the shifts changed, the way boots sounded different on the east walkway after rain. He found the blind spots in the camera feeds, the spots where the lenses stuttered. There was a gate in Sector 3 that gave a particular squeal and creak a full three seconds before it opened. He noticed how the soldiers' faces sagged after a long patrol outside, how their grips tightened on their rifles when a civilian moved too fast, how their eyes never stopped scanning — inside threats, outside threats, it made no difference to them.
One blistering afternoon, a forklift dropped a crate of canned goods in the central square and the whole place erupted. Children and adults alike surged forward, shoving, grabbing, a frantic mob of hunger, while soldiers barked themselves hoarse trying to hold a line. Ethan stood at the edge of it and watched the way he'd watched water find its level — the arc of a falling can, the gap opening where the crowd pressed hardest, the exact second a soldier's attention would swing. When the scramble burned itself out, he walked to a stack of empty barrels in the corner, reached underneath, and came up with a single overlooked can, perfectly intact. That night on his cot he ate canned peaches slowly, one syrupy slice at a time, and it was the best thing he'd tasted in months.
He was still "Ghost" to the other children — the strange, silent boy who moved like water and saw too much, whose quiet intensity made them keep their distance. But the pragmatic officers noticed something else: a kid who never caused trouble, who finished his work, who seemed to know when a pipe was about to burst or a generator was about to fail before anyone else did. They started giving him harder tasks. He took them without a word.
At night, lying on his cot with the dormitory's restless murmurs washing over him, he would find the scar without looking — fingertips tracing the jagged line across his calf, the ridged seam of it, the place where teeth had gone in and death had not followed. Immune. The word sat in his mind like a stone in still water. He was safe from them, the groaning, shuffling horrors beyond the walls. But the secret walled him in tighter than any concrete. To speak it would be to become a specimen. A prize. A threat.
His parents surfaced in his thoughts on those nights, unbidden. Their secret military work — the clipped calls, the long absences, the way they'd vanished one day without a word or a grave. It connected to all of this somehow. He could feel it in his bones, the way he'd once felt weather coming.
Around him the dormitory breathed in its sleep. His fingertip kept moving over the scar, back and forth, back and forth, and he did not sleep for a long time.
