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.

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. </instructions>

The iron gate at Richmond Park stood open. Rory had not expected that. The park closed at dusk. The council locked the gates. A chain and a sign and a bored man in a high-vis jacket made sure of it. Tonight the chain hung slack. The lock kissed the wet ground. The sign swung. She killed the engine of her moped and stared through the dark. The Heartstone burned against her collarbone. It had started on her shift. Heat, then a throb, then a pulse that matched nothing human. Yu-Fei had taken one look at her face and told her to go home. Rory had not gone home. The pendant tugged. A compass needle with a single mind. It pulled her south-west, through streets slick with rain, to this gate, to this impossible opening. She slipped the moped onto its stand. "You have got to be kidding me." Her voice fell flat against the trees. No echo. The air swallowed sound. She touched the pendant. The crimson caught no light from the streetlamps behind her and yet it held light. A deep red that lived under the surface. It pulsed. Warm, then cool. Warm, then cool. Against her skin it beat out a rhythm that made her own heart seem off-tempo. Rory stepped past the threshold. The change hit at once. The city cut out. No traffic on the A3. No planes. No hum from the flats. Richmond Park at night kept a hush, but this hush possessed weight. The oaks crowded close. Their trunks shone black with rain. The path in front of her was not the path she remembered from daytime jogs. The gravel had turned to soft earth. Wildflowers pushed through it, white and yellow, open at midnight. She knew the stories about the Grove. Stories Eva used to tell after last call, when Silas had gone down to the cellar and the bar belonged to just the two of them. A pocket. A fold. Old stones that marked a place where time ran thin. She had laughed then. She did not laugh now. "Alright. I'm here. What do you want?" The pendant answered with another surge of heat. It tugged forward. Deeper in. Rory moved. Her trainers sank into loam. The smell of petrichor rose thick around her ankles, mixed with honeysuckle. Honeysuckle in November. Wrong. An owl called. Or something that wanted to sound like an owl. The hoot started right and finished wrong, too long, the note bending down at the end into something wet. Rory stopped. She turned her head. Her straight black hair stuck to her neck. She had tied it back before her shift. Strands had come loose. Behind her, the gate was gone. Not hidden by dark. Gone. The path behind her ran into trees. Ancient oaks, their branches interlocked overhead, their bark furrowed with lichen that glowed faint in the dark. No break. No road beyond. Her breath snagged. "Okay. Okay. Funny." She reached for her phone. No signal. The screen showed 23:47. The numbers flickered. 23:48. 23:47. She shoved it into her jacket pocket. Her left wrist throbbed where the small crescent scar sat pale against her skin. Old nerves. The pendant pulled. Rory followed because standing still felt worse than movement. The wildflowers brushed her shins. The air grew colder with each step. Her exhale showed. The trees thinned and then stopped, as if afraid to come closer. The clearing opened. Eight standing stones formed a rough circle, each one an oak trunk twisted by age into the shape of a pillar, roots clawed deep into black soil. In the centre, the grass lay flat in a perfect ring, pressed down by something that had lain there long. Rory had seen pictures. Hikers posted them. Isolde's grove. It felt smaller at night. The sky above showed no stars. A flat, bruised violet that gave no sense of height. "Is anyone here?" Her voice cracked this time. Something answered. Not in words. A shift in the grass on the far side of the circle. A ripple against the wind. The wildflowers trembled. Rory stepped back. Her heel hit a root. A light came on between the stones. Not a torch. Not a bulb. The air itself lit, a thin seam of gold that outlined the space between two of the oak pillars. The Heartstone flared. Heat seared her chest. She hissed and grabbed it. The silver chain bit into her neck. The seam widened. A breath of other air slipped out. It smelled of summer and iron and distant fires. Shapes moved on the other side. Tall. Too tall. Limbs that bent in places limbs should not bend. She caught the glint of eyes, too many, set too high. Rory let go of the pendant as if burned. "No." The word tore out of her. Raw. She scrambled back. The root that had caught her heel now looped over the top of her foot. It tightened. Bark slid against her trainer with a soft creak. The oaks had not moved. She knew the oaks had not moved. And yet the root held. She kicked. Her foot came free. Soil clung to her laces. The gold seam thinned. The shapes beyond pressed closer. A sound came through, a whisper that layered over itself, a chorus of voices all saying one thing with different mouths. It took her a second to parse it. It used her name. Not Rory. The other name. The one she had not heard in years. "Laila." Her birth name. The name her mother had whispered against her forehead when fever held her at seven years old. Ice shot down her spine. Her knees locked. "Who's saying that?" The grass in the centre of the stone circle rose. No wind touched it. It rose straight up, blades stiff, pointing at the violet sky. Then it fell. In the pressed ring, an imprint formed. Shoulders. A torso. Legs. As if someone lay there still. The whisper came again, closer. From behind the stones. From under the soil. From the oak pillars themselves. "Laila. You came back." Rory spun. No one stood behind her. The trees stood silent. But at the edge of her vision, something darted between trunks. A flicker of black hair, straight and shoulder-length, just like hers. It vanished when she looked straight at it. Her heart hammered against the pendant. Two rhythms out of sync. She yanked the chain. The clasp held. She yanked again. The chain snapped. She threw the Heartstone into the grass. The stone landed in the imprint. The crimson light died. For a heartbeat, nothing moved. Then the wildflowers around the Heartstone blackened. Petals curled inward. Stems snapped with soft pops. The blight spread outward in a perfect circle from where the pendant lay. The seam of gold between the standing stones slammed shut. The dark returned, absolute. The violet sky pressed low. In that dark, Rory heard footsteps that were not hers. Soft. Bare. Circling the outside of the stone ring. Slow. Patient. She crouched. Her hands found cold earth. Her fingers dug in. The crescent scar on her wrist showed white. "Stay back." Another footstep. Closer. The grass near her left ear rustled. A voice spoke right next to her, from a mouth at ground level, warm breath that stirred her hair. "You shouldn't have left it here."
