You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

Rain splattered against the scuffed windows of the abandoned Tube station, the flickering strip lights turning each drop into a tiny, wobbly star. Detective Harlow Quinn stepped over a puddle that hadn’t been there a second ago, her shoes disturbing the dust settled across the cracked platform tiles. The air smelled of damp stone and something older—ozone, maybe, or spoilt meat left to rot in the dark. Behind her, the tunnel entrance yawned like a rotting mouth, sealed with rusted corrugated iron that didn’t quite fit. Quinn pressed her palm against it. Cold seeped through her fingers, the kind of chill that didn’t come from the weather. Her leather watch, its face scratched with age, read 3:17 AM. Full moon. Of course. A shadow detached itself from the gloom near a stack of broken crates. "Early bird catches the worm, Detective." Quinn didn’t turn. She knew the voice of Detective Sergeant Gary Ellis from the Yard well enough—though not well enough to trust him. "Evening, Ellis. Or should I say morning. Depends on which clock you’re looking at." She finally faced him. Ellis was younger, mid-thirties, dressed in a rumpled suit too warm for the damp. His cheeks were flushed, either from the cold or the excitement, and his tie—some gaudy print—hung askew. Quinn had seen that tie before. It had been Morris’s favourite. A pang shot through her chest, but she kept her voice flat. "Show me what we’ve got." Ellis gestured toward the back of the platform. The space between two support columns had been sectioned off with police tape, the kind that crinkled in the breeze creeping through the tunnel. Beneath it, the body lay sprawled, limbs twisted like a marionette with cut strings. A man, late twenties, dark hair, expensive watch still ticking despite the blood pooling under his wrist. A professional. Quinn didn’t recognise him, but that didn’t mean anything. She crouched beside him, brushing aside a strip of yellow tape. The body was still warm. Too warm. She checked the watch—3:32. Rigor mortis wouldn’t set in for hours, especially not in this cold. Dead only minutes, maybe. "Name?" "Didn’t have ID. Place was clean. Wallet’s gone, phone too." Quinn lifted the man’s jacket with her pen. No wallet. No phone. But beneath his shirt, tucked into a sealed plastic evidence bag tied with a zip-tie, was a small brass compass. The casing was verdigrised, green with age, freckled with sigils etched into the metal. Her stomach clenched. She stood abruptly. "Where the hell did this come from?" Ellis shrugged. "Not mine. Found it in his jacket lining. Thought it might be worth something." Quinn’s fingers hovered over the compass without touching it. The sigils glowed faintly in her peripheral vision—like embers in dark water. She exhaled through her nose. "Did you see anything else? Anything… off?" Ellis frowned. "Off? Like what?" "Like this." She waved a hand over the corpse. "He’s not stiff. He’s too warm. And look—his pupils. Pinpricks. Never seen that before." Ellis leaned in, squinting. "Might be drugs. Fentanyl analogue. I’ve seen that in OD cases." "Fentanyl?” Quinn’s voice was steel. “He wasn’t breathing. I checked. And his lips—blue, but not from suffocation. From something else. Like his blood’s... clotting too fast." Ellis stepped back slightly. "You’re not saying what I think you’re saying." Quinn pulled a pair of latex gloves from her pocket and snapped them on. She reached toward the compass. "Don’t touch that!" Ellis snapped. She paused, eye fixed on the artifact. "Why not?" "Because it’s lying seem dangerous. And it’s evidence." Quinn slowly turned her head. Ellis was gripping his own wrist, knuckles white. "Ellis. What aren’t you telling me?" He hesitated, then tugged his cuff back. A fresh bruise circled his wrist—dark, almost purple, like a handprint. Too precise to be an accident. Quinn’s breath hitched. She reached for the compass again. Ellis grabbed her arm. "Don’t, Quinn. Morris said those things warp time. Or bleed memory." Quinn froze. Morris. The name hung between them like a curse. She yanked her arm free. "You knew Morris?" Ellis jaw tightened. "Briefly. Before… before he went dark." Quinn ignored the jab. She turned the compass over. On the back, etched into the metal, was a name: *Aurora Vey.* A whisper of memory surfaced—Morris’s voice, strained: “They’re using her as the anchor. Like the others. The Veil’s thinning. She doesn’t know.” Her pulse spiked. Footsteps echoed from the tunnel entrance behind Ellis. A woman stepped into the dim light—curly red hair tucked behind round glasses, a satchel slung across her chest. Her green eyes scanned the scene, landing on the body, then the compass. "Quinn?" Eva Kowalski’s voice was steady, but her freckled hands clenched the satchel strap. "What the hell is this?" Ellis turned. "Kowalski? You weren’t—" "I told you I’d meet you here," Eva cut in, stepping closer. Her gaze flickered to the compass, then to Quinn’s face. "You found it, didn’t you?" Quinn didn’t let go of the compass. "You know what this is." Eva nodded. "Veil Compass. Points to rifts. And it doesn’t point to *where* it is. It points to *when* it was made." Ellis laughed nervously. "That’s—that’s not science." Eva pulled a book from her satchel—leather-bound, pages yellowed. She flicked to a marked page. “Page 178 of *The Black Ledger*. Records from a 1781 Veil Market auction. Item: Veil Compass, sold to a shadow dealer named Vey. Descendant line held the artifact for six generations. Until Aurora." Quinn’s fingers trembled around the compass. "Aurora Vey." Eva nodded. "She’s the one keeping the Veil from closing. At least, that’s the rumour. She’s not supposed to exist." Ellis frowned. "What do you mean, *not supposed to exist*?" Eva’s eyes darted to the body, then back. "Because Vey bloodlines were wiped out in the 1800s. Unless someone’s been hiding her." Quinn felt the world tilt. The air grew thick, humid. The compass pulsed faintly in her grip. Then the strip lights flickered again. This time, they didn’t come back on. In the sudden dark, Eva’s voice cut through: "Quinn. Don’t look at it. Don’t look at the woman behind you." Quinn didn’t need to turn. She already felt the cold breath on her neck. The taste of copper in the air. Something moved in the tunnel mouth. A silhouette—tall, draped in something that shimmered like tar in moonlight. A woman with long dark hair, her face caught in the eerie glow of something not quite light. Aurora Vey. And she was smiling.
