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 last bus dropped her at the Sheen Gate with a hiss of brakes and a driver who never looked back. Rory stood on the verge and watched the red taillights shrink along the road until the dark swallowed them. Park lamps stopped at the edge of the tarmac. Past that line lay bracken, oak, and the pale shapes of deer that lifted their heads and went still. The pendant rested against her breastbone beneath her jumper. For three nights it had held a steady warmth, like a palm pressed over her heart. Tonight the warmth had sharpened into something she could count. She pulled out her phone. 11:52. One bar of signal, no messages, and a map she had drawn from a 1870s survey scan that showed a ring of stones where no ring should exist. She locked the screen and shoved the phone into her coat pocket anyway. It felt heavier than a phone had any right to feel. "Right, then," she muttered, and the sound of her own voice came back to her a fraction late, flat against the trunks. The path narrowed into a deer track. Her boots found the softer patches of earth without her asking them to. Honeysuckle hung thick in the air, sweet enough to coat the back of her throat, and when she brushed a low branch she found it heavy with blossom. In the second week of November. She pulled her hand away and wiped her fingers on her jeans. The petals had already begun to turn toward her, the way a sunflower tracks the light, except there was no light to follow. No birds sang. Richmond in autumn should have been loud with wood pigeons and the rattle of jays, but the silence had a texture to it, like wool pulled tight over the ears. Then came the knocking. Three slow raps, wood on wood, somewhere off to her right. She stopped. The sound stopped with her. She took one step, and the knocking came again, three raps, a fraction after her boot touched the ground, as though whoever made it had learned her rhythm and decided to keep time. "Who's there?" she said. The question rolled out between the oaks. Something answered it, not with words but with a soft double tap, and then nothing. She kept walking because turning around felt like the bigger mistake. Her footsteps came back to her a half beat late, so that for a moment she heard two women walking, one slightly behind the other. She stopped again. The second set of footsteps stopped too, a breath after she did. The pendant pulsed. It was not the steady heat of the last three nights. It throbbed against her skin in a rhythm that matched her pulse until she could no longer tell which was which. Movement flickered at the edge of her vision, low and pale between two trunks. She turned her head. Bark, moss, a fern drooping with dew. Nothing else. She turned back and the pale shape sat there again, a little closer, a little taller, shaped roughly like a person who had forgotten how a person should stand. When she looked straight at it, it was a shadow between shadows. She pulled her phone out again and checked the time. The minute hand jumped backward by three, then settled at 11:52 as though it had never moved at all. "Okay," she said quietly. "That's not normal." Ahead, the oaks thinned and the ground rose into a slight hump. The stones stood on it, six of them, grey-green and leaning inward like mourners around a grave that had been dug and left open. Lichen crusted their faces. Ivy wound around their bases. Between the two tallest, the air shimmered in a way that had nothing to do with heat. She could see the trees on the far side, but they looked wrong, too far apart and too tall, like a photograph of a painting. The pendant burned now, a sharp, insistent heat, and a faint crimson glow seeped through the cloth of her jumper. She pressed her hand over it and felt the gem thrum beneath her palm, quick and eager, the way a dog strains toward a door. She had come to find out why it had been warm for three nights. She had come to find out who had put it around her neck and why they had never signed a card. Standing in the wet grass with the honeysuckle breathing on her skin, she realised she had never asked herself whether she wanted the answer. Her footsteps had stopped. She was still moving. Her boots pressed forward into the grass, one step, two, toward the gap between the stones, and the silence behind her grew heavy enough to lean against. Then breath touched the back of her neck, slow and cool, and it came from exactly where her own should have been.
