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.

A character is alone in a strange, isolated place at night. They came here for a reason, but something feels off from the moment they arrive. The wrongness builds slowly — sounds that shouldn't be there, things that move at the edge of vision, a growing certainty that they are not alone. Build tension through restraint, not through gore. Use the codex entries above as your world reference for the character and setting. Only include the prose of the scene without any markdown or commentary.

The iron gate of Richmond Park groaned on its hinges, a sound like a wet cough swallowed instantly by the heavy, damp air. Aurora pulled the collar of her jacket higher against her neck, her fingers brushing the small crescent-shaped scar on her left wrist. The metal was cold, a sharp contrast to the strange, steady heat radiating from beneath her shirt. The Heartstone Pendant rested against her collarbone, no larger than a thumbnail, pulsing against her skin with a faint, rhythmic warmth that felt too much like a heartbeat. She had come because the note left on her threshold had specified midnight, and because the desperate need to understand the weird, creeping rot bleeding into her life outweighed the common sense screaming at her to stay in the flat above Silas' bar. But the moment her boots crunched onto the gravel of the outer path, the world tilted just enough to make her stomach roll. The city sounds were entirely absent. No distant drone of the A307, no hum of traffic, not even the thin whistle of the wind through the London suburbs. Instead, the night was muffled, wrapped in a thick, wet silence that pressed against her eardrums. A dense fog clung to the grass, glowing with a sickly, phosphorescent sheen that made the ancient oaks look less like trees and more like skeletal ribs reaching up from a shallow grave. Aurora checked her phone. The screen was dead. Not a low battery flicker, but absolute black, the glass reflecting her own pale face and bright blue eyes like a mirror smeared with grease. "Right," she muttered, her voice falling flat and dead in the heavy air. "Bloody brilliant, Rory." She turned off the main path, cutting across the damp turf toward the perimeter she knew by heart. Except nothing here was quite where it should be. The distance felt warped, stretched out like pulled taffy. She walked for what should have been five minutes, her breath pluming in short, grey puffs, yet the familiar ridge of the hill remained frustratingly distant, hovering just out of reach beyond the wall of fog. Then came the sound. It wasn't the scuttle of a fox or the rustle of a late-flying owl. It was a rhythmic, wet dragging sound, coming from somewhere off to her left. *Slip, scuff. Slip, scuff.* Like something heavy and boneless being pulled across mud. Aurora stopped dead, holding her breath. The pendant against her chest gave a sudden, hard throb, hot enough to sting. In the periphery of her vision, a shape detached itself from the trunk of a massive oak. It moved with an unnatural, fluid jerkiness, sliding around the bark as if its body had no fixed joints. She whipped her head around to look directly at it, but the space was empty. Just twisted branches and drifting mist. She swallowed hard, her mouth tasting of copper and ash. Think, she told herself, forcing her racing pulse to steady. Cool-headed. Out of the box. If she was where she thought she was—if the stories whispered by the old delivery boss at the restaurant had any grain of truth—she had crossed a threshold she shouldn't have. She kept walking, her eyes darting constantly from side to side. The ground beneath her boots felt wrong, too spongy, giving way with a soft, sucking sound like decaying peat. At the edge of a clearing, the ancient oak standing stones loomed up out of the fog. They stood in a broken circle, jagged pillars of grey stone wrapped in thick, pale vines that bloomed with heavy, swollen wildflowers, their petals dripping a clear, viscous nectar that smelled faintly of bruised plums and iron. In the center of the ring, something was waiting. It was tall, impossibly elongated, standing with its back to her. It wore a coat that seemed made of woven shadow, tattered at the hem where it pooled onto the wet grass. As Aurora stepped closer—compelled by a dreadful, magnetic pull she couldn't resist—the figure slowly turned its head. It didn't turn its shoulders. Its neck simply unspooled, rotating a full three hundred and sixty degrees with a sickening, wet crackle like dry twigs snapping beneath a boot. A face stared back at her from upside down. There were no eyes, only smooth, pearlescent skin where features should have been, stretched tight over a skull that was far too wide. A slit of a mouth parted, revealing rows of needle-thin teeth, and a sound issued from it—not a voice, but the terrifying mimicry of her own mother calling her name from across an empty house. *Rory? Are you down there, love?* The pendant flared hot enough to burn, a deep crimson light bleeding through the fabric of her shirt. Aurora didn't scream. Panic was a luxury for people who weren't staring into the dark. Instead, she backed away one slow, deliberate step, her fingers curling into the heavy metal of the chain, ready to run. And as the thing in the clearing began to fold its impossible limbs to step out from the stones, the fog around her rushed inward, swallowing the world whole.
