You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

Only include the prose of the scene without any markdown or commentary.

Her first shot went wide, spanging off the tunnel wall in a shower of sparks that smelled like ozone and burnt rubber. The recoil jarred her shoulder, but she compensated instantly, bringing her aim back on target as Herrera lunged behind the table. The severed hand rolled across the floor like a lost dice. Quinn moved forward, her boots splashing through a puddle that wasn’t water—it was thick and viscous, clinging to her soles with every step. The psychotropic venom still fogged her thoughts, but the adrenaline cut through it, sharp and clean. She wasn’t here to hallucinate. She was here to arrest him. Herrera kicked the table over, sending jars shattering. One shattered against the dome, and the fireflies inside exploded in a silent storm, their light glinting off every wet surface in the chamber. Shadows writhed like living things. “You really want to do this down here?” Herrera shouted over the sudden silence. “Amongst *them*?” Quinn didn’t answer. She fired again, this time putting a bullet through the medallion around his neck. The Saint Christopher shattered, its pieces scattering like teeth across the wet stone. Herrera gasped, clutching his chest as if struck, but his eyes burned with something deeper than pain. She closed the distance between them just as he straightened, her free hand grabbing the front of his coat and slamming him against the chamber wall. The impact sent more of those glowing droplets raining down, sizzling where they hit the floor. “Where’s Morris?” Quinn demanded, her voice low and raw. “What happened to him in that warehouse?” Herrera’s breath hitched. For a second, she thought he might actually tell her. But then his gaze flicked past her shoulder, and his mouth twisted into something between a scowl and a grin. “Too late,” he said. Quinn turned. The chamber’s domed ceiling had split open. Not cracked—*split*—as if something beneath had stretched too wide, too fast. The fireflies poured out in a river of golden light, surging toward them like a swarm of living embers. The air hummed, a frequency that vibrated in Quinn’s teeth, her fillings, the marrow of her bones. Herrera twisted free, knocking her back. She stumbled, nearly losing her footing in the slick muck, and caught herself against the wall as the swarm engulfed him. He didn’t scream. He didn’t struggle. He *absorbed* them, his body glowing from within, his dark skin illuminated in flickering highlights of amber and crimson. Quinn raised her weapon again, but the fireflies were already retreating, withdrawing back into the dome as if pulled by invisible strings. They left behind a scent—ozone, burnt hair, something like old pennies. And there, on the floor where Herrera had stood, was nothing. No body. No blood. No scarred forearm. No Saint Christopher medallion. Just a single black feather, still warm to the touch. Quinn stared at it, her mind racing. Eighteen years of policing, and she’d never felt this helpless. Not even when Morris died. She bent down, picked up the feather. It pulsed once against her fingertip, like a heartbeat. Then it went still. The chamber was quiet now. Too quiet. The market’s hum was gone. The stalls. The barterers. All of it—vanished like it had never been. Quinn was alone. She straightened, her breath fogging in the suddenly frigid air. The tunnel behind her, the one that led back to the stairs? Just a dark hole now, its edges blurred as if the tunnel had always been a lie. A whisper slithered up from the sewer grate at her feet—Herrera’s voice, but deeper, layered, as if spoken by a dozen throats at once. *You don’t belong here, Detective.* Quinn’s grip tightened on her Glock. She didn’t lower it. “Wrong,” she said. “I belong everywhere.” She stepped forward, into the dark. The tunnel accepted her.
