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 Richmond Park had been chained since dusk, so Rory went over the wall by the Ham entrance, the way Eva had shown her, dropping into wet bracken with the pendant swinging cold against her sternum. Cold. That was the first wrong thing, though she didn't recognise it as wrong yet. The Heartstone had never been cold. Warm as a swallowed mouthful of tea, always, even in January, even when she'd left it in the drawer for a week out of spite. She pressed her palm over it and walked north-east, counting the stiles. The park at night was not the park at day. She'd expected that. What she hadn't expected was how the deer were arranged — she came over a rise and there were maybe forty of them standing in the bracken with their heads all turned the same direction, east, away from her, motionless as furniture. Not one grazing. Not one flicking an ear. She stopped and looked at them for the space of ten breaths, and in ten breaths not one of them moved, and then she made herself keep walking, because she had eleven hours until Yu-Fei expected her at the restaurant and because Isolde had said *come alone, come at night, come before the moon is full or don't come at all.* The moon was one night short. She had counted twice. The standing stones came up out of the dark the way a person does in a crowded room — suddenly, and already too close. Eight oaks, though *oak* was a courtesy; they had gone hard and grey and grainless as stone centuries ago, and something about the way they leaned inward made her think of shoulders hunched over a card table. She'd been here three times before. Three times the space between them had smelled of cut grass and honey and something green she had no word for, and three times she had felt the boundary give like a beaded curtain. Tonight the air between the stones smelled of pennies. Rory stood at the threshold with her breath going white and told herself: *pennies is nothing. Iron in the soil. Blood is iron, iron is blood, it's chemistry, it doesn't mean anything.* Cool-headed. That was the thing her father said about her when he was being kind, and the thing he said about her when he wasn't. She stepped through. Inside, the wildflowers were blooming. Of course they were; they always were, that was the whole trick of the place, cornflowers and campion and great white umbels of hogweed standing up out of the frost in the last week of November like they'd never heard of it. She let out a breath she hadn't known she'd banked. The grove was intact. The grove was fine. Then she noticed they were all facing her. Not the way flowers face light — she knew what that looked like, she'd had a sunflower on a windowsill in Cardiff that swivelled like a satellite dish all summer. This was every head turned inward toward the centre of the clearing, toward the flat pale stone where Isolde liked to sit, and Rory happened to be standing in front of it, and so the entire grove appeared to have taken an interest. "Isolde," she said. The word went out of her and didn't come back. No echo, obviously, there was nothing to echo off — but there was also no absorption, no soft dying-away into the trees. It simply ended, the way a recording ends. Like something had caught it. She waited a full minute. She was good at waiting; she'd learned it in a flat in Cardiff, standing very still in a hallway, timing a man's breathing. "Isolde, it's Rory. Aurora. You told me to come." Nothing. And then, from somewhere to her left, past the elder tangle: the small wet tick of a dripping tap. There were no taps in Richmond Park. Rory turned her head slowly. Drip. Drip-drip. Steady, patient, domestic. It was the sound of the kitchen tap in the flat above Silas' bar, the one that needed a washer, the one she'd listened to at three in the morning for a hundred nights while the bass came up through the floorboards. She knew that sound the way she knew her own pulse, and hearing it here, in a pocket between worlds, made something behind her sternum fold up small. *It's water off the leaves,* she thought. *It rained at six.* It hadn't rained at six. She crossed to the flat stone. Her boots made no sound in the flowers, which was fine, which was normal; the grass here was thick as carpet. On the stone lay a small dark heap that resolved, as she crouched, into a bundle of pale ribbon wound round a lock of red hair. Isolde's ribbon. Isolde's hair. It was tied with a knot Rory didn't recognise, seven or eight loops of it, the sort of knot you tie when you have time and no hurry and you want the thing to hold. She did not touch it. Behind her, the dripping stopped. Rory stayed crouched. The skin across her shoulders drew tight, and she had the sudden animal certainty — no evidence, no sound, nothing you could put in front of a jury — that the clearing had one more thing in it than it had thirty seconds ago. That it had come in past the stones without troubling them. That it was standing where she'd been standing at the threshold, in her footprints, filling them. She counted three, and turned. The hogweed stood in the moonlight, eight feet tall and white as bone, and there was nobody there. But the flowers had turned again. All of them. Every head that had been facing the centre of the clearing now faced the western gap between two stones, and they had done it silently, in the four seconds her back was turned, and Rory understood with a cold clean clarity that the flowers were not looking at her at all. They had never been looking at her. They had been looking at whatever was walking a slow circuit of the grove's inside edge, and they were tracking it the way a field of eyes tracks a fox. *Right,* she thought. *Right. All right.* She stood up. She got the pendant out from under her collar and held it in her fist, and the deep crimson of it was flat and dull as a boiled sweet, no glow at all, and that was the third wrong thing and the worst one, because Silas had told her — with that particular flat delivery he used when he wasn't joking — that the Heartstone went dark for exactly one reason. Something in the elder shifted. Not a footstep. A settling, like a large animal changing which leg it stood on. "I don't want anything," Rory said, and was pleased that her voice came out level. "I came for Isolde. I'll go." The wildflowers turned as one, ninety degrees, and faced her. Very slowly, from the dark under the elder, something began to breathe in the rhythm of a dripping tap. Rory did not run. Running was what you did when you'd already lost your nerve, and her nerve was the only thing in this grove that still belonged to her. She walked — steady, unhurried, twelve feet to the eastern gap — and she kept her eyes on the flowers rather than the trees, because the flowers would tell her where it was, the flowers were honest, the flowers were the only honest thing left in here. Six feet from the stones, every head in the grove swivelled to point at the eastern gap. At the way out. Ahead of her. Rory stopped. Her heartbeat filled her whole body, patient and enormous, and above the treeline the moon sat one night short of full, and somewhere behind her the ribbon lay knotted eight times on the stone, holding. Then, quite softly, from the gap between the oaks, a voice that was very nearly Isolde's said: "You came alone. Good girl."
