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.

The abandoned Tube station hummed with the stale, damp breath of the earth beneath Camden. Detective Quinn adjusted the strap of her worn leather watch as she stepped into the dim glow of a flickering emergency light. The air smelled of rust and something older—something that coiled at the back of her throat like a warning. She’d been sent here to investigate the disappearance of a local occultist, but the body she found wasn’t what she expected. The victim lay sprawled across the cracked concrete floor of the old station, her curly red hair matted with something dark and viscous. Eva Kowalski, her best friend and the occult researcher, had been the one to call Quinn in. She’d found the body near the farthest corner, where the air felt thicker, heavier than the rest of the station. Quinn’s instincts prickled. This wasn’t a simple homicide. “Quinn,” a voice cut through the silence. She turned to see DS Morris standing just inside the entrance, his uniform crisp despite the damp. His jaw was set, his eyes sharp with the kind of focus that meant he’d been here before. “You’re late.” “Morris,” Quinn said, voice low. “You’re here.” Morris exhaled through his nose, the sound sharp. “I was told to check in. You know how this place gets.” Quinn didn’t. But she knew enough to know that the Veil Market moved like a shadow, shifting its locations on the full moon, and this station had been abandoned for years. The bone token they’d found at the entrance—it wasn’t just a key. It was a door. Morris crouched beside the body, his gloved fingers brushing the red curls. “She’s been here a while. The wounds aren’t fresh.” “And the blood?” Quinn asked, stepping closer. The stain on the concrete was too deep, too *wrong*. It didn’t pool like human blood. It clung, like something had been drawn into the earth itself. Morris didn’t answer right away. He was already scanning the area, his gaze flicking toward the far wall where the emergency lights cast long, jagged shadows. “You see that?” Quinn followed his stare. The wall wasn’t just cracked. It was *breathing*. The cracks pulsed, like veins, and the air between them seemed to shift, though no wind stirred. “Morris,” Quinn said, voice tight, “what the hell is this place?” Morris stood, his expression unreadable. “It’s not a place. It’s a *threshold*.” A threshold for what, Quinn didn’t know. But she’d seen enough in her years on the force to know that when the supernatural got involved, the rules didn’t apply. The body beneath her still didn’t make sense. The wounds were precise, surgical. Not a knife. Not a gun. Something *else*. “Where’s the Veil Compass?” Quinn asked, already knowing the answer. Morris’s eyes darkened. “It’s gone.” Quinn’s fingers tightened around the strap of her satchel. “And the token?” “Gone too.” The station felt colder now. The air thickened, pressing against her skin like a second layer of flesh. Quinn turned back to the body. Eva’s eyes were open, staring blankly at the ceiling. Her mouth was slightly parted, as if she’d been speaking in a language Quinn didn’t understand. Then she noticed it—the faint, almost imperceptible glow around Eva’s wrists. A pulse of light, like a heartbeat, flickering just beneath the skin. Morris stepped forward, his breath steady. “She’s not dead.” Quinn’s pulse hammered in her throat. “What?” “She’s not *dead*. She’s… trapped.” Trapped in what, Quinn didn’t know. But the way Morris said it, the way his voice had hardened, made her stomach twist. This wasn’t just a murder. This was something worse. “What do we do?” Quinn asked, her voice barely above a whisper. Morris didn’t answer right away. He was already reaching into his jacket, pulling out a small brass compass. It was old, its surface worn smooth by years of use, the needle pointing straight at the body. “This,” Morris said, his voice rough, “isn’t just a homicide. It’s a *breakthrough*.” Quinn’s blood ran cold. She’d heard the stories—about the Veil Market, about the things that lurked beneath London’s streets. About the places where the veil between worlds thinned. And now, here she was, standing in one of them. The body beneath her moved. Eva’s fingers twitched. Her lips parted further, as if she were about to speak—but instead, the air around her seemed to *shift*, like the world itself was bending to her will. Morris grabbed Quinn’s arm, his grip iron. “We don’t have time to think. We need to get out of here.” Quinn looked at the body again, at the way Eva’s eyes flickered, as if something inside her was struggling to escape. “What do you mean, get out?” Morris didn’t answer. He just pulled her toward the entrance, his voice urgent. “We’re not leaving until we know what’s happening.” The station was closing in around them. The cracks in the wall pulsed faster, the air thick with an unnatural weight. Quinn could feel it—the pull of something unseen, something waiting just beyond the Veil Market’s shifting borders. And then, from the darkness beyond the station, something *answered*.
