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 gate on Sheen Road had been locked since dusk, so Rory went over the wall, the way Silas told her not to. Richmond Park at half past one in the morning wasn't dark so much as drained. All the colour had run out of it. The grass held the grey of old dishwater and the oaks stood in their scattered congregations like people who had stopped mid-argument, and above it all the sky carried the sick orange bruise of London, too bright for stars. She walked with her phone dark in her pocket. Torchlight would carry for a mile out here, and she had no interest in explaining herself to a park ranger, or worse, to whoever else might be looking. The pendant lay cool against her sternum. That was the thing she kept checking, the way you'd keep touching a tooth that ached. Cool meant no portal. Cool meant she was doing this for nothing, or she was doing it too late, and she hadn't decided which of those was worse. Eva had said midnight. Eva had said the grove, and Eva had said *don't be late, Rory, I mean it, don't you dare be late,* and then Eva had not answered her phone for two days. The standing stones came up out of the ground ahead of her, and Rory slowed. They were oak, not stone, whatever anyone called them — nine trunks stripped of bark and set upright in a rough oval, silvered with age, each one taller than a man and worn smooth in places where hands had touched them for centuries. She'd seen them four times now. She had never once seen them the same way twice. Tonight the gaps between them looked wider than she remembered, and the air above them shimmered faintly, the way tarmac does in August, except it was February and her breath was hanging in front of her face in little ghosts. She stopped at the boundary. Put her palm flat on the nearest trunk. The wood was warm. Not sun-warm. Blood-warm. "Right," she said, out loud, because her own voice was better than nothing. "Fine." She stepped through. The change came the way it always did, all at once and without ceremony, like walking from a corridor into a room. The cold went. The orange sky went. Overhead there were stars, too many of them, arranged in patterns she'd stopped trying to recognise, and beneath her boots the wildflowers of the grove opened in their impossible profusion — foxglove and bluebell and cornflower and dog rose, spring and summer and autumn all crowding each other in the same square foot of earth, glowing faintly with their own light the way certain fungi do. The clearing smelled of crushed green things and honey. It was beautiful. It had always been beautiful. That was the first wrong thing, and it took Rory a moment to understand why: because it was *only* beautiful. It was silent. The grove was never silent. There were always crickets — or something like crickets, some small chittering business in the grass — and always the high thin note of wind moving through the canopy, and always, faintly, water somewhere she'd never been able to find. Isolde had told her once that the water was the grove listening. Rory had assumed that was a fae joke. Fae jokes were usually not. Now there was nothing. Her own footsteps were the loudest thing in the world. "Eva?" The word went out and did not come back. No echo. It should have echoed; the tree line was close enough. She felt the absence of it like a missed stair. She made herself walk to the centre of the clearing, to the flat pale rock where they'd sat in September passing a bottle of stolen wine between them while Isolde watched with the polite bafflement of something very old observing something very brief. The rock was there. On it, folded neatly, was a green scarf. Rory picked it up. Eva's. The awful cheap synthetic one she wore because she liked the colour, the one that made her look, in her own words, like a Christmas parcel. Folded into a perfect square, corners aligned, the way Eva had never folded anything in her life. The pendant against Rory's chest gave one slow pulse of heat, like a heartbeat, and then went cold again. She turned around. The clearing was empty. Of course it was. But the flowers to her left — a dense stand of foxglove, chest-high — were still moving, swaying back into stillness, as though something had passed through them a second ago and she had turned a second too slow. "Isolde," she said. Not a question. An offering. A name given to the air in the hope that something would take it up. Nothing did. Rory's mouth had gone dry. She catalogued facts, because cataloguing facts was what she did when the alternative was running: the scarf was here, folded, therefore placed. Placed meant intent. Intent meant someone had wanted her to find it, which meant someone had known she would come, which meant she was, at this moment, precisely where somebody wanted her to be. She wound the scarf around her fist and started back toward the stones. Walking away from the centre of the grove was harder than walking into it. The distance was wrong. She had crossed twenty metres of flowers to reach the rock and now she had been walking for a minute, two, and the tree line stayed exactly where it was, and her legs kept working, and the ground kept sliding under her, and none of it added up. That was when she heard the breathing. It was very quiet and very close and it was not hers. She knew it wasn't hers because she had stopped, and it hadn't. Three more breaths — slow, deep, patient, the breathing of something at rest — and then it stopped too, all at once, as though whatever it belonged to had only just remembered that breathing was something it needed to pretend to do. Rory did not turn around. She stood in the glowing flowers with her friend's scarf strangling her fingers and she thought, with terrible clarity: *if I turn around, I will see it, and then it will know that I can.* The silence stretched. Somewhere behind her, at the level of her shoulder, close enough that she should have felt the warmth of it, something shifted its weight and a single dry stem cracked. At the edge of her vision, low down among the bluebells to her right, a shape moved. Long. Pale. Moving with the unhurried confidence of something that has already decided how the evening ends. She caught it only as an absence of flowers, a channel opening and closing in the blooms, and it was going ahead of her — cutting between her and the standing stones. The pendant flared against her breastbone, hot enough to sting, and did not stop. "Eva," Rory said, "if that's you, this isn't funny." *Rory.* The voice came from her left, and it was Eva's, and it was perfect — the Cardiff vowels, the little upward hook at the end of her name — except that it came from her left and the flowers on her left had not moved at all, and Eva had never in her life said Rory's name without laughing at some part of it. Rory looked straight ahead at the stones, sixty metres away, or six, or six hundred. She let the scarf fall. She would need her hands. *Rory,* the voice said again, closer now, and behind her the thing that did not need to breathe began, very softly, to breathe again — in time with her own.
