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.

The flickering neon of the abandoned Tube station pulsed like a dying heartbeat. Detective Harlow Quinn stepped over the rusted metal grates, her boots crunching on broken glass. The air smelled of damp earth and something older—something that clung to the walls like a second skin. “You’re sure this is where it happened?” DS Morris’s voice cut through the silence, sharp as a blade. He stood near the entrance, his breath misting in the cold. His jacket was still damp, the sleeves rolled up to his elbows, fingers twitching toward the holster at his side. Quinn didn’t answer. She knelt beside the body, her gloved fingers brushing the back of a skull. The teeth were missing, but the jawbone still held the imprint of a mouth that hadn’t been meant to be. The skin around it was too pale, too *wrong*—like something had been drawn across it before the killer struck. “Morris,” she murmured, “you ever see a face like that before?” Morris exhaled through his nose, rubbing his temples. “No. But I’ve seen worse.” A low hum vibrated through the station, deep beneath the concrete. Quinn’s watch—her worn leather strap—ticked faster. The needle on her wrist didn’t move, but the air did. The shadows stretched unnaturally, pooling around the body like ink in water. “You hear that?” Quinn asked. Morris’s eyes flicked toward the ceiling. “What?” “That’s not the station’s ventilation.” A voice, thin and cracked, slithered from the darkness. *“You shouldn’t be here.”* Eva Kowalski stepped into the light, her curly red hair tangled around her freckled face. She carried a satchel, the leather worn smooth by years of use. Her glasses reflected the dim glow of the station’s emergency lights, but her green eyes were sharp, assessing. “Detective Quinn,” she said, voice steady. “I was just leaving.” Quinn didn’t look away. “You’re in the wrong place, Eva.” Morris shifted, his grip tightening on his gun. “What the hell is going on?” Eva’s fingers twitched toward the satchel. “I was researching something. Nothing to do with you.” “Then why are you here?” Quinn demanded. Eva’s gaze flicked to the body. “Because the Veil Market moved here.” The words hung between them, heavy. Quinn’s jaw tightened. “You’re talking about the Market.” “Yes.” Eva’s voice dropped. “They’re selling things that shouldn’t exist. And the last thing they sold was a man.” Morris’s breath hitched. “You’re saying this wasn’t a homicide.” Quinn’s fingers dug into the corpse’s shoulder. “No. It’s worse.” A rustle came from the shadows. The hum grew louder, vibrating through Quinn’s bones. The brass compass in her pocket—*the Veil Compass*—pulled against her palm, the needle spinning erratically. “What’s that?” Morris asked, voice low. Quinn didn’t answer. She just stared at the compass, at the sigils etched into its face, at the way the light bent around it like a mirage. Then the station trembled. The walls groaned, the ceiling above them splitting open. Something dark and shifting spilled into the station, a swarm of shadows that moved without sound, without form. The air turned thick, suffocating. Eva’s voice was a whisper. “They’re here.” Morris grabbed Quinn’s arm, his grip iron. “We need to go.” Quinn didn’t move. The shadows coiled around the body, wrapping around it like a second skin. The teeth were back in place now, sharp and jagged, but the jawbone was wrong—too thin, too *wrong*. And then the compass lit up. Not with light. With *pain*.
