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 off the platform of the abandoned Tube station, her boots echoing in the cavernous space. The air was thick with the scent of damp concrete and something else—something metallic and sharp. She adjusted the cuff of her coat, the worn leather of her watch brushing against her fingers. The time was 3:17 AM, and the full moon cast an eerie glow through the grime-streaked windows high above. The station was a relic of a bygone era, its once-bustling platforms now silent and still. But tonight, it was far from deserted. The flickering light of police issue flashlights cut through the darkness, illuminating the scene before her. A body lay sprawled near the edge of the platform, the victim's limbs splayed at unnatural angles. The white of a police tent stood out starkly against the grimy surroundings, and a handful of officers moved about with the quiet efficiency of those who had seen too much. Quinn's sharp jaw tightened as she took in the scene. She had been called here by a tip, an anonymous voice on the phone claiming that something was amiss. She had expected the usual—drug deal gone wrong, perhaps, or a territorial dispute among the homeless who sometimes took shelter in the abandoned station. But this... this was different. Her colleague, Detective Marcus Greene, stood near the body, his face illuminated by the glow of his phone. He looked up as Quinn approached, his expression grim. "Quinn," he acknowledged, nodding towards the body. "You're going to want to see this." Quinn crouched down beside the body, her eyes scanning the victim's features. A man in his late thirties, she estimated, with a gaunt face and hollow cheeks. His clothes were tattered, his skin marred by what looked like old scars. But it was the wound on his chest that drew her attention—a jagged gash, as if something had torn through him with inhuman strength. "Cause of death?" Quinn asked, her voice steady. "Exsanguination," Greene replied, gesturing to the pool of blood beneath the body. "But that's not the strange part. Look at his hands." Quinn turned the victim's hands over, her brow furrowing as she examined them. The fingers were stained with something dark and viscous, the nails broken and jagged. And there, in the palm of his right hand, was a small, intricate symbol—a sigil, etched into the flesh. She frowned, her mind racing. She had seen symbols like this before, in the margins of old books, in the notes of a case that had gone cold three years ago. The case that had taken her partner, DS Morris. The case that had left her with more questions than answers. "Any idea what this means?" Greene asked, his voice low. Quinn shook her head, her eyes still fixed on the symbol. "Not yet," she said. "But I intend to find out." She stood, her gaze sweeping over the rest of the scene. The platform was littered with debris—broken glass, discarded syringes, the remnants of a makeshift camp. But there was something else, too. Something that didn't belong. Near the edge of the platform, half-hidden beneath a pile of rubble, was a small, brass compass. Its casing was tarnished with a patina of verdigris, and its face was etched with protective sigils. Quinn's pulse quickened as she recognized it—a Veil Compass, a tool attuned to supernatural energy. She crouched down, carefully lifting the compass from its hiding place. The needle spun wildly before settling on a point directly above the body. Quinn's mind raced as she considered the implications. The Veil Compass was a rare and dangerous artifact, one that was said to point towards the nearest supernatural rift or portal. Its presence here could only mean one thing—the victim had been involved in something far beyond the ordinary. Greene watched as Quinn examined the compass, his expression unreadable. "You know what that is, don't you?" he asked. Quinn nodded, her eyes still fixed on the compass. "I do," she said. "And if I'm right, this case is about to get a lot more complicated." She stood, her mind already racing ahead to the next steps. She needed to find out who the victim was, and what he had been doing with the compass. She needed to find out who had left that symbol on his hand, and what it meant. And she needed to do it before whoever was responsible struck again. But first, she needed to find Eva. Eva Kowalski was a researcher at the British Museum, a woman with a keen mind and a deep knowledge of the occult. She was also the only person Quinn trusted to help her navigate the dangerous world of the supernatural. Quinn pulled out her phone, her fingers flying over the screen as she sent a quick message. Eva's response was almost immediate—a single word, "Coming," followed by an address in Camden. Quinn turned to Greene, her expression serious. "I need to follow up on a lead," she said. "Keep me updated on any developments." Greene nodded, his eyes lingering on the compass in Quinn's hand. "Be careful, Quinn," he said. "This isn't like any case we've worked before." Quinn's jaw tightened, her mind already focused on the task ahead. "I know," she said. "And that's exactly why I need to be careful." She turned and made her way back through the station, her boots echoing in the silence. The compass was heavy in her pocket, its presence a constant reminder of the danger that lay ahead. But Quinn was no stranger to danger. She had faced it before, and she would face it again. Because that was what she did. That was who she was. As she stepped out into the night, the cold air biting at her cheeks, she couldn't shake the feeling that she was being watched. She glanced over her shoulder, her eyes scanning the darkness for any sign of movement. But there was nothing—just the empty street, and the distant glow of the city lights. She turned back, her mind already focused on the task ahead. She had a lead to follow, and a mystery to solve. And she wouldn't stop until she had the answers she sought. The address Eva had given her was a small, run-down apartment building in Camden. Quinn made her way up the stairs, her boots echoing in the silence. The door to Eva's apartment was slightly ajar, and Quinn pushed it open, stepping inside. The apartment was small but cozy, filled with books and artifacts from Eva's research. Eva herself was seated at a small table, her round glasses perched on her nose as she pored over an ancient tome. She looked up as Quinn entered, her green eyes meeting Quinn's with a mixture of concern and curiosity. "Quinn," she said, her voice soft. "What brings you here at this hour?" Quinn pulled out the compass, placing it on the table in front of Eva. "I need your help," she said. "I found this at a crime scene, and I need to know what it means." Eva's eyes widened as she took in the compass, her fingers reaching out to trace the sigils etched into its face. "Where did you find this?" she asked, her voice barely above a whisper. "An abandoned Tube station," Quinn replied. "There was a body—a man with a symbol etched into his hand. The compass was nearby, and it was pointing directly at him." Eva's expression grew grave, her fingers tightening around the compass. "This is a Veil Compass," she said. "It's used to locate supernatural rifts or portals. The fact that it was pointing at the body suggests that the victim was involved in something... otherworldly." Quinn's jaw tightened, her mind racing. "I need to know what that symbol means," she said. "And I need to know who would have the power to create it." Eva nodded, her eyes already scanning the pages of the tome before her. "I'll do some research," she said. "But in the meantime, you need to be careful, Quinn. This is dangerous territory you're stepping into." Quinn's expression hardened, her resolve unwavering. "I know," she said. "But I can't turn away from this. Not when I have the chance to finally uncover the truth." Eva's eyes met Quinn's, her expression softening. "I know," she said. "And that's why I'll help you, no matter what it takes." Quinn nodded, her mind already focused on the next steps. She had a lead to follow, and a mystery to solve. And with Eva by her side, she knew she could face whatever dangers lay ahead. As she stepped back out into the night, the compass heavy in her pocket, she couldn't shake the feeling that she was on the verge of something big. Something that would change everything she thought she knew about the world. And she was ready to face it head-on.
