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 had been falling for hours, a relentless London downpour that slicked the pavement black and turned the city’s usual roar into a muffled, watery thrum. Detective Harlow Quinn, soaked to the bone despite her reinforced trench coat, felt the cold gnaw deep into her muscles, a familiar ache she’d learned to ignore. Her closely cropped salt-and-pepper hair was plastered flat against her skull, water beading on her sharp jawline. Brown eyes, narrowed against the stinging drops, scanned the sparse foot traffic of the Soho back street. She’d been on this stakeout for three hours, tailing nothing but shadows and the occasional late-night reveler. Then, there he was. Tomás Herrera. He emerged from the emerald glow of The Raven’s Nest sign, a quick, furtive glance over his shoulder before he plunged into the downpour. Even through the sheets of rain, Harlow noted the dark mass of his curly hair, the way his olive skin seemed paler against the night, the glint of his Saint Christopher medallion as he pulled his collar tight. He moved with an economical grace that spoke of practiced haste, not panic, but something close enough to it to trip a wire in Harlow’s gut. "Got you," she muttered, the sound swallowed by the rain. She pushed off the grimy brick wall, her worn leather watch glinting on her left wrist. Years of policing had honed her stride to a military precision. She kept her distance, a phantom in the deluge, letting the drumming rain provide cover for her footsteps. Tomás, seemingly oblivious, cut through the narrow street, weaving between overflowing bins and parked cars. He wasn’t running flat out, but his pace was relentless, a man with a destination and the knowledge he shouldn’t be seen. Harlow mirrored him, her gaze fixed on the back of his head. Her breath hitched in her chest, a cold knot of adrenaline tightening in her stomach. This wasn't just another walk-off; this was different. She’d felt it before, that prickle on the back of her neck when the mundane façade of the world threatened to crack. Morris. His name echoed in the hollow space between heartbeats. Three years later and she still chased ghosts, convinced there was more to the inexplicable than bad luck or coincidence. Tomás veered sharply down a dark alley, the kind that smelled of stale beer and desperation. Harlow didn't break stride. Her boots splashed through a shallow puddle, sending spray up her trousers. The alley walls, slick with grime and rain, loomed on either side, swallowing the streetlights. She could just make out his silhouette, a quick, agile blur as he rounded a corner. She pushed harder, her lungs burning, the side of her foot aching from an old injury. Rain lashed her face, momentarily blinding her, but her internal compass was locked on him. She gained ground, just enough to see him glance back. Warm brown eyes, wide with surprise, met hers for a fleeting moment before he surged into a full sprint. The chase was on. He was fast, faster than she’d anticipated. He cleared a low wall with a fluid jump, a movement not typically seen in a man of his build. Harlow hauled herself over, grunting at the effort, the taste of cold rainwater on her tongue. The streets had devolved into a tangle of derelict warehouses and forgotten industrial buildings, each window a black eye staring out into the storm. Graffiti bled down crumbling brickwork, painted over by the rain. Tomás led her deeper into this urban decay, away from the faint hum of central London. No cars, no buses, just the incessant drum of the rain and the echo of their pounding feet. He ducked into a cavernous archway, choked with weeds and draped in a heavy, rusted tarp. Harlow followed, drawing her service pistol from its holster, the cold metal a welcome weight in her hand. Her grip was steady. Her military training surged to the surface, overriding the exhaustion. The archway opened into what looked like a derelict railway sidings—a skeletal network of tracks disappearing into the gloom. But this wasn’t just disused. This felt… preserved. Too quiet. A low, guttural murmur seemed to vibrate from the very ground beneath her feet, a sound like a distant, troubled ocean. Tomás was gone. Harlow stopped, pressing herself against a rain-slicked concrete pillar, pistol raised. Her eyes, accustomed to the city’s artificial glow, struggled in the near total darkness. A sharp metallic tang, like old blood and ozone, stung her nostrils, entirely masking the usual damp earth smell. She scanned the debris, the rusted machinery, the broken concrete. Nothing. He couldn’t have vanished. Then, she caught it—a flicker of movement by what looked like a collapsed tunnel entrance, partially obscured by more rusting sheets of corrugated iron. A faint, anemic glow pulsed from within, barely visible. Tomás. She moved with slow, deliberate steps, her boots crunching on gravel. The air grew colder, heavy and damp, as if she were walking into a freezer. A strange, sickly sweet scent mixed with the metallic tang, something like rot and potent spice. Her gaze sharpened, trying to pierce the gloom. This wasn't just an abandoned tunnel; it felt… old. Ancient. The bricks were hewn in a way she didn’t recognise, too perfect to be modern, too worn to be new. She edged closer, straining her ears. The gentle murmur beneath the earth grew louder, coalescing into a cacophony of hushed conversations, clinking objects, and something like distant cries. What in God's name? Harlow reached the tunnel mouth. Tomás was silhouetted against a strange, undulating light, his hand reaching out, not to a wall, but to empty air. For a split second, she saw a piece of bone, small and gleaming, clutched in his palm. He seemed to press it against an invisible barrier, and then he simply… walked through. The light shimmered, the air rippled, and he was gone. Harlow stood frozen, her pistol still aimed at the spot where Tomás had vanished. The bone token. Its significance exploded in her mind, a piece of old lore that her rational brain had always dismissed as fantasy. Now, it was real. Her heart hammered against her ribs, not just from the chase, but from a deeper, primal fear. She moved to the edge of the opening. It was not a void, but a cavernous space, a vast underground realm that defied logic. This wasn’t just an abandoned Tube station beneath Camden – this was the Veil Market, the whispered myth of the occult underworld, suddenly laid bare before her. A chaotic tapestry of light and shadow stretched out below, a dizzying array of stalls and shadowy figures. Lanterns of strange, iridescent hues cast eerie glows on tables laden with unidentifiable objects. Twisted metals gleamed, strange liquids bubbled in glass vials, and the air buzzed with a hundred alien scents: sulfur, exotic incense, something musky and feral, and the persistent metallic tang. Forms moved through the gloom, not all of them entirely human. Some had too many limbs, or too few, or skin that wasn’t quite right. Hushed voices burbled in languages she didn't recognise, punctuated by guttural barks and high-pitched whispers. A low, rhythmic thrum pulsed through the rock, like a giant, sleeping heart. This was it. The impossible. The irrational. The kind of place Morris had stumbled into, the kind of truth that had cost him his life. Her breath hitched. Every instinct screamed at her to retreat, to call for backup, to write this off as a hallucination brought on by exhaustion and the rain. This wasn't in any police procedural. This wasn’t in her eighteen years of decorated service. But her eyes saw, her ears heard, her nose smelled. Her gut twisted. She lowered her pistol slightly, her hand shaking barely perceptibly. Tomás was in there, a single human anchor in a sea of the grotesque. If she let him go, if she turned her back on this, she lost her lead. She lost her only chance to understand. To understand Morris. The cold grip of the rain still clung to her clothes, but a new, deeper chill seeped into her bones, a cold born of the supernatural. Her sharp jaw was set. She looked at the yawning entrance, at the flickering, chaotic lights, at the shifting, unknowable shapes within. The whisper of ‘Morris’ returned, clearer this time. She took a step forward, the water squelching inside her boots. Duty, or sheer madness. The line blurred into the shadows.
