Low Tier Seven woke before the siren.

  Not because anyone wanted to — but because the shelter never fully slept.

  Someone coughed too hard in the dark. Someone else shifted on stone, joints popping softly. A child whimpered in their sleep until a tired hand reached out and pulled them closer. The drip near the back wall kept its steady rhythm, tapping out time in a way that made it impossible to forget how long you’d been here.

  Kael opened his eyes and stared at the ceiling.

  The stone above him was cracked in long, thin lines, like something had once pressed upward from the other side and failed. He’d counted them once. Stopped when he realized he’d started memorizing which ones leaked during rain.

  Riven lay on his side nearby, one arm flung over his face, breathing slow and even. He always slept like he was bracing for impact — muscles tight, jaw clenched, as if rest itself was something that might be taken away without warning.

  Kael sat up carefully, avoiding the feet and elbows scattered around him.

  The shelter was packed tighter than usual. A reshuffle two weeks ago had pushed more bodies into Seven — older kids from Eight, a few from Nine who hadn’t lasted a full cycle. No one complained. Complaints went nowhere. You just learned how to sleep smaller.

  He stood, stretched quietly, and nudged Riven’s boot with his toe.

  “Bell’s coming,” he murmured.

  Riven groaned. “You say that every time.”

  “And I’m always right.”

  “That’s not a skill.”

  “It is here.”

  Riven snorted but rolled upright, rubbing his face. “If I die of exhaustion, I’m haunting you.”

  “You’ll get in line.”

  The siren wailed moments later — thin, metallic, echoing down through the stone like the city itself was yawning. The shelter stirred in earnest now, bodies untangling, quiet curses muttered under breath.

  They joined the flow toward the exit, shoulders brushing, heat building as too many people tried to move through too little space. Outside, the air was cooler but heavier, tinged with damp and the sour smell of boiled grain already cooking somewhere above.

  Low Tier Seven unfolded around them.

  Stone corridors patched with mismatched blocks. Old support arches reinforced with newer metal braces. Lamps bolted high along the walls, their glow steady but dim — enough to work by, not enough to forget where you were.

  The work halls branched out like veins.

  Kael and Riven headed toward Hall C.

  The noise hit them first — the grind and scrape of stone cutters, the rhythmic clank of presses, the low murmur of dozens of conversations layered over one another. Hall C processed scrap: broken stone hauled down from upper tiers, shattered supports from old collapses, chunks of cursed infrastructure stripped out and rendered inert.

  Unauthorized duplication: this tale has been taken without consent. Report sightings.

  It was mindless work.

  Which made it survivable.

  Kael took his position along the sorting table, fingers already aching in anticipation. Riven dropped onto the bench beside him, rolling his shoulders.

  “You hear about the brace collapse in Tier Four?” someone down the line said.

  “Nah.”

  “Crushed two workers. Took them three hours to dig them out.”

  Riven grimaced. “Alive?”

  A shrug. “Does it matter?”

  The press operator barked for silence, and the line began to move.

  Stone slid toward them in uneven chunks. Kael sorted by weight and fracture pattern, muscle memory guiding his hands more than thought. Clean breaks to the left. Contaminated pieces to the right. Anything that hummed faintly went into the marked bin for later handling.

  He worked fast, not showy. Speed drew eyes. Mistakes drew worse.

  Riven, by contrast, worked like he fought — aggressive, efficient, occasionally reckless. He slammed pieces into place, muttering under his breath when his fingers slipped or a shard bit too deep.

  “You’re rushing,” Kael said quietly.

  “I’m bored.”

  “Bored gets you hurt.”

  Riven flashed him a grin that didn’t quite reach his eyes. “So does slow.”

  Across the hall, a boy Kael recognized — Tomas, Tier Eight — fumbled a piece and yelped as it cracked, cursed residue flaring briefly before dying out. The line paused.

  A guard stepped in immediately.

  Not shouting. Not threatening.

  Just present.

  “You alright?” the guard asked.

  Tomas nodded too fast. “Yes, sir.”

  “Good,” the guard said. “Pay attention.”

  He stepped back.

  The line resumed.

  Kael noticed how everyone exhaled at once.

  By mid-cycle, sweat slicked Kael’s palms and his shoulders burned pleasantly — the dull ache of work done correctly. This was the part of the day he preferred. No thinking. No watching. Just the next piece, then the next.

  At break, they sat along the wall near the water trough.

  Someone cracked a joke about the press operator’s voice giving out someday. Someone else laughed too loudly and got shushed immediately. A girl Kael didn’t know traded half her bread for a strip of dried meat, the exchange quick and wordless.

  Life continued.

  Riven leaned back against the stone. “You notice the guards changed rotations?”

  Kael took a slow drink. “They do that.”

  “Yeah,” Riven said. “But not like this. Same faces, different posts. They’re tighter.”

  Kael shrugged. “Inspection maybe.”

  “Inspection for what?”

  Kael met his eyes briefly. “Don’t know. Don’t care.”

  Riven studied him, then scoffed. “You care.”

  Kael didn’t deny it.

  Someone sat down beside them — Mara, Tier Seven, sharp-eyed and sharp-tongued. She jerked her chin toward the far end of the hall.

  “You two hear about the missing ones?”

  Riven stiffened.

  Kael kept his tone neutral. “Who’s missing?”

  Mara rolled her eyes. “Exactly.”

  She leaned closer, voice dropping. “Three from Eight. One from Seven. Maybe more. Boards say ‘reassigned.’ No one’s seen them.”

  Riven opened his mouth.

  Mara cut him off. “Don’t.”

  He blinked. “Don’t what?”

  “Don’t ask like that,” she said. “You’ll draw attention.”

  Kael’s fingers tightened around his cup.

  Riven frowned. “That’s stupid.”

  Mara smiled thinly. “So is bleeding out because someone decided you were a problem.”

  She stood, brushing dust from her pants. “Just… keep your heads down.”

  And walked away.

  The rest of the cycle passed without incident.

  Which made it worse.

  When the siren finally sounded again, signaling end of shift, Kael felt the familiar mix of relief and dread. Work ended. Waiting began.

  Back at the shelter, the crowd pressed in tighter than before. Someone had taken the empty space where Denzel used to sleep.

  Kael noticed.

  He didn’t comment.

  Riven sat heavily beside him, staring at nothing. “You think Mara’s right?”

  Kael lay back, hands on his chest, eyes on the cracked ceiling. “About what?”

  “That asking questions is dangerous.”

  Kael thought of the guards’ calm faces. The clean boards. The way no one had seemed surprised.

  “I think,” he said slowly, “that asking the wrong questions at the wrong time is dangerous.”

  Riven snorted softly. “Comforting.”

  Kael closed his eyes.

  Around them, Low Tier Seven settled into uneasy rest — breathing, shifting, living.

  Above them, the city continued its work.

  And somewhere within it, people were being moved.
