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 rain poured down in sheets, streaking the neon signs and casting an eerie glow over the city streets. Detective Harlow Quinn scowled as she tightened the collar of her coat, her keen eyes scanning the shadows for any sign of her target. She had been trailing Tomás Herrera for weeks, piecing together his connections to the shadowy clique she suspected was involved in a string of occult-related murders. The man was clever, disappearing into the Soho crowds whenever she got too close. But tonight, she had him dead to rights. Herrera's head swiveled as he glanced back over his shoulder, his gaze meeting Harlow's. His eyes went wide with panic, and he broke into a dead sprint, his leather shoes slapping against the wet pavement. "Freeze! Police!" Harlow shouted, breaking into a run. Her lungs burned as she pushed her body to its limits, the adrenaline coursing through her veins. She couldn't lose him, not this time. Herrera darted around the corner, vanishing from sight. Harlow pushed harder, rounding the bend just in time to see him disappear down a set of stairs leading into the darkness of an abandoned Tube station. Without hesitation, Harlow barreled down the steps, her boots pounding against the concrete. The air grew thick with the scent of damp earth and stale air as she descended into the bowels of the city. The shadows seemed to close in around her, and she could feel the oppressive weight of the city above pressing down. As she reached the bottom, the sound of Herrera's retreating footsteps echoed through the cavernous space. Harlow paused, her eyes adjusting to the gloom. The station was eerily quiet, save for the distant rumble of trains. She drew her service weapon, the metal cool and steady in her grip. "Herrera! There's no way out! Give it up!" she shouted, her voice echoing off the tiled walls. Silence. Harlow gripped her gun tighter, her finger hovering over the trigger as she advanced cautiously into the station. Up ahead, she could make out the faint silhouette of a doorway, its edges illuminated by a soft, flickering light. As she drew closer, the sound of muffled voices reached her ears. Harlow narrowed her eyes, steeling herself for what might lie beyond. With a deep breath, she stepped through the doorway, her gun raised and ready. The scene that unfolded before her was unlike anything she had ever witnessed. The room was dimly lit by a handful of flickering candles, casting long shadows across the space. Shelves lined the walls, filled with an assortment of strange and unfamiliar objects – jars of mysterious liquids, ornate daggers, and what appeared to be ancient tomes. In the center of the room stood a group of people, their faces obscured by hooded cloaks. They turned to face her, and Harlow felt a chill run down her spine at the sight of their blank, featureless masks. "What the hell is this place?" she demanded, her voice sharp and authoritative. One of the hooded figures stepped forward, its movements slow and deliberate. "This is the Veil Market, Detective Quinn. A place where the hidden world of the supernatural meets the mundane. I'm afraid you've stumbled upon something you were never meant to see." Harlow's grip on her weapon tightened, her knuckles turning white. "Where's Herrera?" The figure raised a gloved hand. "The man you seek is long gone, Detective. He has found sanctuary here, where the laws of your world do not apply." Harlow's jaw clenched, her frustration boiling over. "I don't care about your laws or your _sanctuary_. I'm taking Herrera in, and I'm shutting this place down." The figure chuckled, the sound hollow and unsettling. "I'm afraid that won't be possible. This market is a vital part of the balance that keeps our world and yours from colliding. To interfere would be to invite chaos." Harlow felt a bead of sweat trickle down the back of her neck. The air in the room seemed to hum with an otherworldly energy, and she couldn't shake the feeling that she was in over her head. "I don't care about your _balance_ ," she spat. "Herrera is a murderer, and I'm going to bring him to justice, no matter what." The figure raised a hand, and the others around it began to move, closing in on Harlow. "Then you leave us no choice, Detective. You have trespassed on ground that is not yours to walk. For the sake of the Veil, we cannot allow you to leave this place." Harlow's heart pounded in her chest as the hooded figures advanced, their movements fluid and unnatural. She knew she was outmatched, outgunned, and out of her element. But she wasn't about to go down without a fight. With a deep breath, she steeled her nerves and took a step forward, her gun leveled at the approaching figures. "I don't care what you are or what you think you're protecting," she growled. "This is my city, and I'm not going anywhere." The figures paused, their blank masks seeming to regard her with a mixture of curiosity and disdain. Harlow could feel the tension in the air, thick and palpable, as the two sides faced off, neither willing to back down. In that moment, Harlow knew she was standing on the edge of a precipice, staring into the abyss of a world she had never known existed. But she was a cop, and protecting the city was her duty, no matter the cost. With a grim determination, she tightened her grip on her weapon and prepared to make her stand.
