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.

rain lashed against the asphalt of the Camden streets, turning the grime of the city into a slick, treacherous black mirror. Detective Harlow Quinn ignored the cold water finding its way down the collar of her coat. She stood in the shadow of a boarded-up electronics shop, her eyes fixed on the man pacing beneath the flickering halogen of the streetlamp across the road. Tomás Herrera. He looked younger than his twenty-nine years, shivering in a jacket that wasn't built for a London downpour. Through the distortion of the rain, Harlow could just make out the dark curls of his hair plastered to his forehead and the nervous way his hand kept darting to his chest, likely clutching that Saint Christopher medallion he wore. He was a creature of nervous energy, shifting weight from one foot to the other, his olive skin sallow under the sickly yellow light. Harlow checked the worn leather watch on her left wrist. Military precision dictated she wait for him to make the exchange, to catch him red-handed, but something in his posture set her teeth on edge. He wasn't waiting for a dealer. He was checking his six. He looked up, scanning the dark storefronts. His gaze swept over her hiding spot. Harlow didn't flinch, betting on the shadows and the rain to cloak her, but Herrera’s eyes widened. He had the instincts of a prey animal. He didn't wait to confirm. He bolted. "Police! Stop!" Harlow’s shout was a command, honed by eighteen years of shouting down drunks and murderers, but it vanished into the roar of the rain. She broke cover, her boots hammering the pavement. Herrera had a lead, but he was skittish, slipping on a wet grate as he rounded the corner. Harlow took the turn tight, her sharp jaw set, the muscles in her legs burning as she shifted gears. She was forty-one, no longer the sprint champion she had been at the academy, but she had endurance and a predator's focus. Herrera scrambled over a chain-link fence that blocked off an alleyway undergoing construction. Harlow hit the mesh seconds later. She didn't climb; she vaulted, using the momentum to swing her legs over, landing in a crouch that jarred her knees. "Herrera!" she barked, seeing him disappear behind a stack of pallets. She navigated the debris, her hand hovering near the firearm at her hip, though she didn't draw. Not yet. Herrera was a paramedic, or he used to be, before the NHS stripped his license. He wasn't known for violence. But the people he worked for—the ones inhabiting the back rooms of places like The Raven’s Nest—they were a different breed. The alley narrowed, funneling them toward the skeleton of an old industrial sector. The noise of current London fell away, replaced by the rhythmic slap of their footsteps and the hiss of the downpour. Herrera was looking back now, fear etched plainly on his face. He wasn't running from an arrest; he was running like his life depended on it. He took a sharp left toward a rusted iron gate set into a brick archway. It looked like a service entrance to the Underground, long abandoned and welded shut. Harlow pushed harder, closing the distance. "Nowhere to go, Tomás," she muttered, breath pluming in the cold air. But Herrera didn't slow down. He didn't brace for impact against the locked gate. Instead, he reached into his pocket. His hand came out clutching something small and white. He slammed his palm against the rusted metal plate of the door mechanism. Harlow skidded to a halt ten feet away, hand gripping her pistol now. "Hands where I can see them!" Herrera ignored her. He was muttering something, frantic and low. The air around the gate seemed to warp, a sudden drop in pressure that popped Harlow’s ears. The rust on the gate didn't break; the metal simply... conceded. The heavy iron groaned, not with the shriek of age, but with a deep, resonating thrum that vibrated in Harlow's chest bones. The gate swung inward, revealing a darkness thicker than the night. "Don't do it," Harlow warned, though her voice wavered. A memory flashed—DS Morris, bleeding out in that warehouse three years ago, the air smelling of ozone and something rotten, the physics of the room bending in ways that shouldn't exist. Herrera looked back at her one last time. The rain dripped from his nose. "Go home, Detective," he shouted, his voice cracking. "You don't have a token." He slipped into the darkness, and the heavy gate began to swing shut. Harlow didn't think. The adrenaline surge overrode the logical part of her brain that screamed about traps and jurisdiction. She lunged forward. Her boot caught the bottom of the iron door just before it sealed. The metal pressed against her sole with the weight of a hydraulic press. She grunted, jamming her shoulder into the gap, leveraging every ounce of strength she possessed. It wasn't just heavy; the door felt alive, resisting her intrusion. Then she saw it—lying in the mud where Herrera had stood. He must have dropped it in his panic. A small, polished piece of bone, carved with symbols that hurt her eyes if she stared too long. She snatched it up with her free hand. The moment her skin touched the bone token, the resistance in the door vanished. The heavy iron became light as balsa wood. The gate swung open silently, inviting her in. Harlow stood on the threshold, rain dripping from the brim of her hair, water soaking her coat. Ahead, a concrete stairwell spiraled down into the earth. The air wafting up was dry, smelling of incense, burnt copper, and old paper. It was the smell of a tomb that had been opened. She pocketed the bone token and drew her weapon properly, holding it at the low ready. "Dispatch, this is Quinn," she said into her radio lapel. "Suspect entering disused station off... Camden High Street." Static. Not the normal scratch of interference, but a high-pitched, harmonic whine. "Dispatch?" Silence. She was off the grid. The realization should have stopped her. It broke every protocol in the handbook. But she had seen Herrera vanish into the earth, and she had felt the door yield to a piece of bone. The answers to Morris's death were down there. She could feel it in the scar tissue of her memories. Harlow Quinn stepped into the darkness, and the gate slammed shut behind her. The stairs were endless, tiled in the cracked, creamy ceramic of the early 20th-century Tube stations. The deeper she descended, the further the temperature dropped. The sounds of the storm above were replaced by a low, murmurous hum, like a chanting choir heard through a thick wall. When she finally reached the bottom, the corridor opened up into what should have been a platform. It was unrecognizable. Makeshift stalls forged from scavenged wood and velvet drapes lined the platform edge. The tracks, where trains should have been rushing by, were covered in planks to create a wider floor. Lanterns burning with flames that shifted from violet to sickly green provided the only light, casting long, dancing shadows against the curved tunnel walls. This was the Veil Market. Harlow holstered her weapon but kept her hand on the grip. To draw a gun here felt like bringing a knife to a nuclear test—useless and provocative. The figures moving between the stalls ignored her, or perhaps they simply didn't care. Some looked human; others wore hoods pulled low, their movements too fluid, too elongated. She saw a jar on a nearby table containing a beating heart suspended in amber fluid. She saw weapons made of glass that hummed. She spotted Herrera near a stall draped in heavy tapestries, fifty yards down the platform. He was arguing with a vendor—a hunched figure whose skin looked like parchment. Harlow moved. She adopted her patrol walk—shoulders back, eyes scanning, exuding an authority she didn't feel. She needed to close the distance before he vanished into the labyrinth of tunnels. Herrera turned, sensing her approach. His eyes went wide, the color draining from his face until the scar on his forearm stood out as a stark white line. "You followed me," he whispered as she stepped into his personal space, backing him against the tapestry. "I told you to stop," Harlow said, her voice dropping to a low, dangerous register. She grabbed his arm, spinning him around and slamming him chest-first against a wooden pillar. "Hands behind your back." "Are you insane?" Herrera hissed, not fighting the hold but twisting his neck to look at her. "You can't arrest me here. Look around you, Quinn!" "I don't care where we are. You're coming in for questioning regarding the distribution of controlled substances." "Controlled substances?" Herrera let out a jagged, hysterical laugh. "I was buying bane-dust to keep a werewolf from tearing apart a flat in Shoreditch. You think your laws apply down here?" Harlow tightened her grip on his wrist. "Explain. Now." "Let me go," Herrera pleaded, his eyes darting to the shadows beyond the lantern light. "The market moves. If we don't leave before the shift, we’re trapped until the next full moon. And the Warden doesn't like tourists." Harlow followed his gaze. The shadows at the far end of the tunnel were lengthening, detaching themselves from the walls. They formed shapes—tall, gaunt silhouettes with no faces. "You wanted to know about the clique?" Herrera whispered, the fear in his voice genuine and infectious. "You wanted to know what happened to Morris?" Harlow flinched. "Don't say his name." "He came here too," Herrera said rapidly. "He found the Nest. He found the Market. He didn't listen when I told him to run." The humming noise in the station grew louder, vibrating in the soles of Harlow's boots. The violet flames in the lanterns flared. "We have to go," Herrera urged. "Now, Detective. Or you end up just like him." Harlow looked at the terrified man, then at the encroaching shadows. She released his arm, but dropped her hand to her belt, gripping the bone token in her pocket with one hand and her gun with the other. "Lead the way," she said, her voice steel. "But once we're topside, you're going to tell me everything. Every. Single. Thing." Herrera nodded, rubbing his wrist. "If we make it topside." He turned and sprinted back toward the stairs. Harlow followed, the darkness of the Veil Market nipping at her heels, the weight of the impossible world pressing down on her shoulders. She had stepped through the looking glass, and she knew, with a sinking dread, that she could never truly go back.
