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 standing stones came out of the fog like teeth. Rory stopped the bike thirty yards short of them, killed the engine, and let the silence rush in. Richmond Park at half two in the morning had a particular quality of quiet — the sort that made you aware of your own pulse in your ears, of the wet click your throat made when you swallowed. She pulled off her helmet and hung it on the handlebar and stood there a moment, breathing air that tasted of cold soil and something faintly sweet, like fruit going over. The pendant under her jacket was warm. Not hot. Warm the way a mug of tea is warm forty minutes after you've forgotten it. "Right," she said, to nobody. Her breath didn't fog. That was the first wrong thing, and she noticed it and filed it away and pretended she hadn't. The message had said midnight. She was two and a half hours late because Yu-Fei's Friday rush had run long and because a woman in Clapham had made her wait eleven minutes on a doorstep for exact change, and because Rory had spent forty minutes after that sitting on her bed with the phone in her hand, deciding. *The grove. Midnight. Come alone or don't come.* No name. No number that resolved to anything when she'd tried it. She walked. The grass beneath her boots gave too easily, sodden, and each step made a small sucking noise that seemed to arrive a half-beat after her foot lifted. Between the stones the fog thinned, and beyond them — Beyond them, wildflowers. In February. Bluebells and cowslip and something with pale trumpet-shaped heads that she didn't have a name for, all of it standing perfectly upright in the windless dark, all of it faintly luminous, as though it had swallowed a summer's worth of light and was letting it out slowly. Rory stepped through. The temperature changed. Not warmer — different. The cold stopped touching her skin and started sitting alongside it, patient, like a dog that had been told to wait. "Hello?" The word went out and didn't come back. No echo. In a clearing this size, ringed with oaks, there ought to have been something. She turned a slow circle. Twelve stones, or thirteen; she counted twelve and then counted again and got thirteen and decided not to count a third time. Grass cropped short as a churchyard. In the centre, a flat pale rock about the size of a card table, and on it, arranged with care, a cup. Rory did not touch the cup. She crouched instead, forearms on her knees, and looked at it. Wooden. Old. Something dark and still inside it that reflected no light at all, not even the flower-glow, not even her own face leaning over it. The stone underneath was dry. Everything else in the grove was wet through and this stone was dry as bone. "Not falling for that one," she muttered. *Something moved behind her.* She was up and turned before she'd decided to be, hand already inside her jacket, fingers closing on nothing because she hadn't brought anything worth closing them on. The treeline stood exactly as it had. Nothing swayed. Nothing settled. But there had been movement — low, quick, at the very outside edge of her sight, the specific shape of a person crossing a doorway. "I know somebody's out there. You wrote to me. Come on then." Nothing. She counted her own heartbeats to twenty. Then, from somewhere on her left, quite clearly: the sound of a small child laughing. Rory's whole body went cold in one sheet, scalp to heels. It was such an ordinary sound. That was the horror of it — not a shriek, not a moan, just a kid's giggle, two notes, breathy, the sort of thing you heard forty times a day in a park in daylight and never once thought about. It came from perhaps twenty feet away, at about hip height, and there was nothing there. "Okay," she said. Her voice came out level and she was grateful to it. "Okay." She started walking towards the stones. Not running. Running was how you told a thing you were prey. The laugh came again, ahead of her now, in front of the gap she was aiming for. She changed course. Angled left, towards a different gap between different stones, and kept her breathing slow and shallow through her nose, and when she reached the boundary she put her hand out to steady herself on the oak — — and the oak was warm. Warm like a flank. Warm like something with blood in it. She snatched her hand back and stepped through the gap and the flowers were still there. Rory stood very still. Behind her: flowers, stones, flat rock, cup. Ahead of her: flowers, stones, flat rock, cup. Same arrangement. Same thirteen stones, or twelve. Same wooden cup with its little pool of nothing in it. "Fine," she said. "Fine. That's how we're playing." The pendant against her sternum was hotter now. Not comfortable. She dragged it out on its chain and the crimson stone lay in her palm pulsing like something with a heart, and by its light she could see her hand shaking, and she watched the shake with a kind of clinical distance, the way you'd watch someone else's hand. "Where's the door, then? You've dragged me out here—" The grass to her right pressed flat. A patch of it, maybe three feet across, the blades bending outwards from the centre in a ring, as though something heavy had set itself down. She heard the weight of it — a soft crush, an exhalation of air from between stems. Then, six feet from that, another patch went flat. Then another. It was walking. Towards her. And she could see the grass bow under it and could not see it, and the space where it ought to have been was not empty and not dark and not anything; her eyes slid off it the way they slid off a word she couldn't read. Rory took one step back. The grass stopped bending. She took another. Nothing. *Don't run.* She could hear her father's voice saying it, absurdly, about a dog on the Cardiff sea wall nineteen years ago. *Don't run, Rory, they only chase what runs.* The child laughed again. Directly behind her left shoulder. Close enough that she felt the small warm push of breath on her neck. She didn't turn. "You're not a kid," she said, and her voice cracked in the middle and she hated it. "You've heard one. You're doing the sound. That's all that is." Silence. A long one. Long enough that she began to think she'd got it right, that naming the trick had spent it. Then the laughing started again, and this time it didn't stop, and it didn't breathe, and it went on and on in exactly the same two notes, over and over, from somewhere just past her ear, without any pause at all for air.
