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.

Detective Harlow Quinn stepped into the abandoned tube station, her boots clicking on the concrete platform. The stale air, heavy with the scent of rust and decaying leaves, sent a shiver down her spine—not from the cold, but from the eerie feeling that lingered in this hidden place. The faint glow of gas lanterns flickered, casting long shadows that danced like malevolent spirits. This was the Veil Market, a supernatural black market that defied earthly norms, and it held secrets she was determined to unveil. She had received an anonymous tip about a disturbance at this location, and her instincts, honed over 18 years in the Metropolitan Police, told her it was no ordinary crime scene. As she scanned the deserted platforms, the absence of any market activity confirmed that something had indeed gone very wrong. "Detective Quinn!" A familiar voice called out from the shadows, and a figure stepped forward. It was Detective Constable Walker, her trusted colleague and the officer who had been first on the scene. "DC Walker," Quinn acknowledged with a nod, her sharp eyes taking in the surroundings. "What have we got here?" Walker, a younger man with a nervous twitch to his eye, rubbed his hands together as if trying to generate warmth in the damp underground space. "A real odd one, ma'am. Looked like the Market was setting up shop, but something spooked them. Everyone scattered, and it's been dead quiet since." Quinn's gaze darted around, taking in the evidence. Abandoned stalls lined the platform, displaying wares ranging from mundane to the otherworldly: a crystal ball, vials of shimmering liquid, and ancient-looking tomes. A forgotten cup of tea had gone cold, steam no longer rising from its surface—a detail that suggested a hasty departure. She stooped to inspect a peculiar item, a small brass compass with an intricate face. "The Veil Compass, crafted by a Shade artisan," she murmured, recognizing the tool from her research. Its needle spun lazily, seemingly confused by the absence of the supernatural energy it was attuned to. "This device points toward the nearest rift or portal. The Market's location jumps around because of its otherworldly connections, and the compass helps them navigate." "Right, ma'am," Walker said, a hint of impatience creeping into his voice. "So, they packed up and skipped town. Maybe a rival gang got wind of their operation." Quinn straightened, her eyes narrowing. The explanation was too simple, too convenient. A woman's intuition told her this wasn't just another turf war. "Show me where they set up the stalls." They walked down the platform, their footsteps echoing off the curved walls. "Here, see? They were getting ready for business. Customers started arriving, but then..." Walker's voice trailed off as he gestured at the abandoned items. "Something made everyone run." Quinn nodded, her keen eyes noticing the fine layer of dust that covered the goods. She traced a finger through it, disrupting the delicate pattern. "This dust is fresh, kicked up from the tracks beneath us. The Market hadn't been here long before they took off." "Makes sense they'd keep moving, hard to pin down like a ghost," Walker mused. "Not much we can do if they don't want to be found." "That's where you're wrong," Quinn said firmly. Her belief that justice could be served, even in this shadowy world, burned bright. "This place is more than an illicit trade hub. It's a community. And someone scared them off." Walker's brows knitted together, his confusion evident. "But nothing's been touched, no signs of a fight. If someone had spooked them, why wouldn't they take their goods and go? Valuable stuff here, someone would've pocketed a trinket or two." Quinn's brown eyes scanned the distant tunnels, her mind racing. "That's because it wasn't an external threat. No rival gang or police raid caused this evacuation. It was something from within. Perhaps a dispute or..." She trailed off, her face hardening. "You remember the Thorne case?" A look of understanding flashed across Walker's face. "The disappearances a few years back, linked to that abandoned warehouse near the river. Rumors of occult activity. Someone messed with forces they didn't understand." "Exactly. And DS Morris," Quinn said, her voice turning steely, "my partner, was one of the casualties. The official report was inconclusive, but I've always suspected supernatural involvement." Walker nodded, his face a mix of empathy and confusion. "I'm sorry, ma'am. But what does this have to do with the Veil Market?" "The Market's bone tokens," Quinn continued, her mind connecting the dots. "Entrance is granted to those who possess one, but the tokens are passed down within families or sold for steep prices. They're a closely guarded secret. So, how did our perpetrator access this hidden world, and why did they flee without a trace?" As if on cue, a chill wind snaked its way down the tunnel, rustling the papers of a stall and sending a shiver down Walker's frame. Quinn's eyes glinted with determination, the cold having no effect on her. "Check the security cameras, see if they caught anything that can help us identify who or what caused this disturbance." "Yes, ma'am," Walker replied, his breathing visible in the frigid air as he ventured down the platform. Quinn remained, her gaze fixed on the spinning needle of the Veil Compass. Her intuition, sharpened by years of policing, told her a familiar evil was at play, one that she had chased for too long without answers. She would not rest until the truth was brought to light, even if it lay in the darkest corners of London's underworld. As the quiet station seemed to hold its breath, Detective Harlow Quinn stood resolute, ready to confront the mysterious forces that had entered her jurisdiction, knowing full well that in this unusual world, nothing was ever as it seemed.
