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 at the Sheen Cross entrance had been chained since ten, so Rory went over the wall. She landed badly in the wet grass, felt the shock of it travel up through her ankles into her knees, and crouched there for a moment with her hands flat on the ground, listening. Richmond Park at half past one in the morning was supposed to be silent, and it was, but the silence had a texture to it — a low hum underneath, like a room with the lights off but the television still warm. She'd been here in daylight. Twice. The first time by accident, following a delivery address that turned out not to exist, and the second time on purpose, and both times the grove had let her walk in and out again like she was nothing worth noticing. That was the thing she kept turning over in her head as she started across the open ground toward the treeline. Nothing worth noticing. It had felt almost insulting at the time. Now she found herself hoping for it. The pendant lay cold against her sternum. She'd checked it three times on the bus. Frost hadn't come yet but the air had the smell of it, that mineral edge, and her breath went out ahead of her in pale rags. Somewhere off to her left a deer coughed — that awful bark they make, more dog than deer — and she stopped dead and stood very still until it came again, further off, and she could laugh at herself a little and keep going. The standing stones announced themselves before she saw them. Not visually. The ground changed. Wet grass gave way to something springier, drier, and the hum she'd half-noticed at the wall dropped an octave, settled into her back teeth. She could see the oaks now, six of them, black against a sky the colour of dirty water. They weren't planted in a circle exactly. More like they'd all agreed to stand roughly here, at roughly these intervals, and no one had checked their work in nine hundred years. Between two of them the air was wrong. That was the only way she could put it. Like looking through a window with rain on it, except the rain was on the inside. "Right," she said aloud, and her voice came out thin. "Isolde. I'm here about the girl." Nothing answered. She hadn't expected anything to. That wasn't how it worked — you went in, and then you were somewhere else, and then the negotiating started. She'd rehearsed it on the bus too, the whole thing, the order of the questions, the exact words she would not use. She stepped through. The cold went out of the air all at once. Not warmth exactly — an absence of cold, which was somehow worse, like stepping into a bath at body temperature and losing track of where your skin ended. The grove opened around her, and it was as she remembered: a bowl of clipped green ringed with wildflowers that had no business flowering in November. Cornflowers. Poppies. Foxgloves stacked like little bell towers. The light came from nowhere in particular, a soft grey-gold, and the sky overhead was a single unbroken sheet of nothing. Rory stood at the edge with her hands loose at her sides and understood, immediately, that something was different. Last time there had been sound. She hadn't registered it as a feature until now, but there had been: a stream she never found, and insects, and now and then a bird making a noise like a cracked bell. Now there was nothing. Not the hum from outside. Not her own footsteps in the grass, which she noticed when she took two more steps and heard absolutely nothing at all. She stopped. Cleared her throat. Heard that fine — heard it too well, in fact, close and dead like the inside of a car. "Hello," she said. The word went about four feet and stopped. Rory made herself breathe. Cool-headed. That was the thing she was, allegedly. That was what Eva said about her and what her mother said about her with rather less approval, and it had got her out of a house in Cardiff with a rucksack and forty quid, so she trusted it. She catalogued. Grass: correct. Flowers: correct, though the poppies had shut, and she wasn't sure poppies did that. Standing stones behind her: still there, six of them, arranged in their careless not-quite-circle, and she counted them twice because the second count came out seven and she needed it not to. Six. Fine. Fine. She walked toward the centre, where a flat pale stone sat in the turf like a dropped coin, and that was where she was supposed to wait. She'd waited there before for perhaps ten minutes and Isolde had come from the west, walking, ordinary as a woman crossing a car park. The poppies to her right moved. Rory didn't turn her head. She kept walking, and she watched the movement from the corner of her eye, and it was a rippling, a bending of stems away from something passing between them, and it travelled in a smooth line parallel to her own path, about fifteen feet out. She stopped walking. The rippling stopped. "I know you're there," she said, and the flatness of her own voice in the dead air frightened her more than the flowers had. "I'm here to speak to Isolde. That's all. I've got a name and I want to trade for it." The poppies were still. Every one of them. She counted eight breaths. Then she turned her head fully and looked, and there was a patch of grass out there, maybe twenty feet away, that was flattened. Not trampled. Pressed, in a broad shallow oval about the size of a person lying down, and the blades hadn't sprung back. Rory looked away and kept going to the stone and sat down on it, because her legs had begun to feel unreliable, and sitting was a decision and she wanted to be making decisions. The pendant, under her jumper, was warm. She put two fingers against it through the wool and felt the heat come through, gentle and steady, no more than a mug of tea left twenty minutes. It had never done that. Silas had told her — *if that thing ever goes warm on you, you walk, Rory, you don't run, you walk, because running tells them what you are* — and she'd nodded and filed it under things drunk men say behind bars. She stood up. Slowly. The flattened oval in the grass was gone. There was a new one, closer, at maybe nine feet, and she had been looking in that direction for the last thirty seconds and had not seen it appear. "Okay," Rory said. She turned toward the stones. They were further away than they should have been. Not absurdly — not a nightmare distance — just wrong by about a third, the way a corridor is wrong when you've had a fever. The grey-gold light had thickened at the edges of the bowl, gone the colour of tea, and the wildflowers along the rim had all closed. Every species. Cornflowers didn't close either. She was fairly sure about that. She began to walk. Behind her, in the perfect soundlessness, something exhaled. It was very soft, and very long, and it had the particular wetness of breath that has come out through a mouth rather than a nose, and it was not more than three feet from the back of her neck. She felt the temperature of it on the small hairs there — warmer than the air, near enough her own. Rory did not run. She walked, with her chin level and her arms swinging and her heart going like a bird in a box, and she counted her steps in her head because counting kept her from listening. Twelve. Thirteen. The stones came closer at their sullen rate. At twenty she heard the grass part behind her, unhurried, matching her pace exactly, and at twenty-four she heard it on her left as well. The pendant burned now, a coal against her chest. At thirty-one she reached the oaks, put her hand on the nearest one, and found the bark warm as skin under her palm — and stopped, because the space between the stones where she had come in was full, filled up, occupied by something that let no light through and did not move at all. "Excuse me," Rory said, very politely, into the dark. The dark said her name. Not *Rory*. Not *Aurora*. It said *Malphora*, in a voice like a door in another house closing, and it stepped aside to let her through.
