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 gate on Sheen Gate Road was locked, so Rory climbed the railing with her courier bag slung across her chest, the strap biting into her collarbone. Her trainers found wet bracken on the far side. Behind her, the traffic along Kingston Road dwindled to a hiss, then to nothing, as if someone were turning the city down one notch at a time. She checked her phone. 11:52. One bar of signal flickered and died. "Right," she muttered. "Let's get this over with." The pendant had been warm for three nights. At first she'd put it down to the radiator in the flat above Silas' bar, or to the heat of her skin after a double shift on the bike, but the warmth had a rhythm to it now, a faint pulse against her sternum like something knocking politely at a door. She pulled the silver chain out from under her jumper. The crimson stone caught what little moonlight filtered through the oaks and held it, glowing from the inside like an ember that refused to go out. She let it fall back against her skin. It throbbed once, then again. The path wound uphill between bracken taller than her hips. Fallow deer had been roaring all evening, a rough, guttural sound that carried across the park like someone dragging a bin lid over concrete. She'd heard it from the bus stop and thought nothing of it. Now the roaring had stopped entirely, and the silence sat on her shoulders with a weight she couldn't account for. Her torch beam swept over the ferns. Something pale stood among them, perhaps twenty yards off. She stopped. The beam settled on a stump, pale with fungus, its top split and rounded like a bowl. She breathed out. Her shoulders loosened, then tightened again when she noticed the flowers. Foxgloves grew along the path, their purple bells open to the cold. Clusters of bluebells had pushed up through the leaf litter, and a single white rose climbed the trunk of a dead birch. It was the third week of November. She'd walked this route in the summer, and nothing had bloomed then except nettles and the odd dandelion gone to seed. She crouched and touched a foxglove. The petals were cool and papery, but the stem beneath her fingers was warm, the way a living wrist would be. She stood up fast and wiped her hand on her jeans. "Don't be daft," she said. Her voice sounded thin, swallowed almost as soon as it left her mouth. "Plants do that. Some of them flower in winter. Probably." The path ended at the standing stones. There were seven of them, ringed in a rough circle, their surfaces furred with grey lichen. They were oak, not stone, though she'd read the signs and knew they had been planted, not carved, centuries ago. Their trunks had been stripped and bleached and set upright in the earth, and somewhere in the years since, they had stopped looking like anything a person would plant. Their bark had split into deep fissures that looked more like wounds than grain. The gaps between them were exactly as wide as a grown man could walk through. Rory counted them twice. Seven. Then she counted again and got eight. She didn't remember a single one of them being there the first time she'd visited. She'd been sure of that. She would have remembered a stump with a face. The pendant pulsed hard against her chest, three quick beats, and the warmth spread outward until her skin prickled under her jumper. She walked into the circle. The ground inside was softer than the path, springy with moss and fallen petals. The air smelled of rain on hot iron, though the sky above was clear and hard with stars. Her footsteps made no sound. She listened for the crunch of her own trainers and heard only the low hum of the grass pressing back against her ankles. A branch cracked behind her. She turned. The beam of her torch found nothing but tree trunks and bracken. She waited. The night held its breath with her, and she could hear her own pulse in her ears, too fast and too loud. "Hello?" she called. Her voice came back to her flat and strange, as though the trees had swallowed the echo before it could return. Nothing answered. She swung the torch in a slow arc across the stones. The beam caught movement at the edge of the light, the brief pale flicker of something turning away, and then it was gone. She held the light on the spot. Bracken, ferns, a rotten log furred with white fungus. She counted her breaths. Ten. Twenty. The log did not move. But when she lowered the torch, the shadow between the two nearest stones was deeper than it had been. It had edges now. It stood the way a person stands when they are waiting to be noticed. Rory did not look directly at it. She kept her eyes on the grass and drew a slow breath through her nose. "Whoever you are," she said, and was pleased that her voice did not shake, "I'm not here to take anything. I came because someone sent me a pendant and a note, and the note said to come to the grove on the thirteenth night of the month. So either you're the one who sent it, or you're the reason it's hot against my chest like a bloody hob." The stones were silent. The pendant beat once, twice, and then settled into a steady throb that matched her heartbeat, as if the two had agreed to keep time together. Behind her, very softly, something began to hum. It was a tuneless sound, low and patient, and it came from every direction at once.
