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 the pavement as Quinn dashed down the dimly lit alley, her boots splashing through puddles. The air was thick with the scent of ozone and damp brick. Her quarry was just ahead, his dark silhouette darting around the corner. "Stop!" Quinn shouted, her voice hoarse. "Metropolitan Police! Freeze!" The figure ignored her commands, picking up speed. Quinn gritted her teeth and gave chase, her lungs burning as she pounded after him. She'd been on Herrera's trail for weeks, ever since the tip had come in about his involvement with the clique's underground medical operations. Now she was tantalizingly close to finally making an arrest. The alley opened up onto a bustling Soho street, neon signs flickering in the rain. Herrera zigzagged between pedestrians, narrowly avoiding collisions. Quinn followed, her eyes locked on his back as she shoved past startled onlookers. Herrera ducked down a set of metal stairs leading beneath the street. Quinn cursed under her breath and picked up the pace, taking the steps two at a time. The air grew colder and the sound of the rain muffled as she descended into the damp, dimly lit tunnel. Herrera was nowhere to be seen. Quinn paused, chest heaving, and scanned the area. The tunnel stretched out in both directions, the walls lined with old tiles and exposed pipes. A faint scent of incense and something metallic hung in the air. Movement caught her eye off to the left. Herrera was hurrying toward a set of heavy metal doors at the end of the tunnel, a bone-white token clutched in his hand. Quinn took off after him, drawing her Glock. "Stop!" she yelled again, the echo bouncing off the walls. "You're under arrest!" Herrera glanced over his shoulder, his face a mask of panic. He fumbled with the token, shoving it into a slot in the door. With a groan of metal, the doors swung open, admitting him. He slipped through, slamming them shut behind him. Quinn didn't slow her pace, barreling toward the doors. She tried the handles, but they were locked. Peering through the narrow window, she could see Herrera disappearing down another dimly lit tunnel. "Damn it," she muttered, stepping back. She knew she should call for backup, but every second counted. Taking a steadying breath, she squared her shoulders and pushed the doors open, stepping through. The tunnel beyond was narrower and more claustrophobic, the air thick with the scent of burning sage and spice. Strange symbols had been etched into the tiles, glowing faintly in the gloom. Faint whispers and the distant sound of music drifted through the shadows. Quinn moved cautiously, her gun raised, eyes darting from side to side. She couldn't shake the uneasy feeling that she was being watched. The hairs on the back of her neck prickled. After a few tense minutes, she reached another set of doors. These were made of solid iron, with a small barred window set into the center. Taking a deep breath, Quinn peered through. Beyond lay what seemed to be an abandoned underground station, the platforms and tracks long since reclaimed by time. But it was no longer a simple subway stop – stalls and makeshift shops had been set up, their wares displayed under the flickering light of lanterns and candles. Strange, otherworldly items glinted in the gloom, their purpose indecipherable. Quinn's eyes widened as she took in the bizarre scene. This must be the Veil Market – the underground supernatural black market that had been the subject of so many rumors and urban legends. She'd never imagined she'd actually set foot in such a place. Gripping her gun tighter, she pushed the doors open and stepped through, her senses assaulted by the cacophony of sounds and smells. Vendors called out in strange, guttural languages, haggling with customers shrouded in dark cloaks. The air was thick with the scent of spices, incense, and something more primal that Quinn couldn't quite place. She scanned the crowd, searching for any sign of Herrera. There – a familiar figure was disappearing down a shadowed stairwell on the far side of the platform. Quinn surged forward, weaving between the stalls and dodging past startled onlookers. As she neared the stairs, a vendor stepped into her path, a toothy grin splitting his leathery face. "Care to take a look at my wares, detective?" he croaked, his voice raspy. "I have many fine and rare items, just for you." Quinn barely spared him a glance. "Out of my way," she snapped, shouldering past him. The vendor's grin widened, revealing rows of jagged teeth. "Careful, detective," he called after her. "The Veil is not a place for the faint of heart." Quinn ignored the warning, her focus solely on the fleeing figure of Tomás Herrera. She couldn't afford to be distracted, not when she was this close to finally making an arrest. She'd come too far to turn back now. The stairs led down to a dimly lit service tunnel, the air thick with the scent of damp earth and something else, something almost primal. Quinn gripped her gun tighter, her heart pounding in her ears as she hurried after Herrera. The tunnel opened up into a cavernous space, the ceiling lost in darkness. Strange, flickering light sources cast an eerie glow over the scene, illuminating a maze of stalls and makeshift shelters. Quinn paused, taking in the surreal tableau. This was unlike anything she'd ever seen – the Veil Market was more than just a simple black market, it was a whole other world, hidden beneath the surface of the mundane. The vendors here peddled wares that defied all logic and reason, their origins shrouded in mystery. Quinn shook off her momentary awe and pressed on, her eyes scanning the crowd for any sign of Herrera. She had to focus, had to keep her head in the game. This was no time to be distracted by the fantastical. As she wove her way through the maze of stalls, a sense of unease began to creep up her spine. The vendors and customers alike were casting furtive glances in her direction, their expressions unreadable. She could feel their eyes following her every move, and the hairs on the back of her neck stood on end. Suddenly, a hand clamped down on her shoulder, and Quinn whirled around, her gun raised. A tall, hooded figure stood before her, its face obscured by the shadows. "You should not be here, detective," the figure said, its voice low and rumbling. "The Veil is no place for the likes of you." Quinn's finger tightened on the trigger, but before she could react, the figure raised a hand, and the world seemed to shift and warp around her. She blinked, disoriented, and the figure was gone, as if it had never been there at all. Cursing under her breath, Quinn pressed on, her senses on high alert. She had to find Herrera, and she had to do it before the strange denizens of the Veil Market decided to interfere. The tunnel opened up into a larger space, and Quinn's eyes widened as she took in the scene before her. Rows of stalls lined the walls, their wares a dizzying array of the strange and the otherworldly. In the center of the space, a large, circular dais stood, its surface covered in intricate carvings and symbols. And there, standing on the dais, was Tomás Herrera, his face a mask of fear as he clutched a small, glowing amulet in his hand.
