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 Sheen Cross had been chained since ten, so Rory went over the wall. The brick was cold and damp under her palms, slick with the kind of moss that only grew where London kept its back turned. She landed on the far side in a crouch, ankle-deep in wet bracken, and stayed there a moment, listening. Traffic hummed somewhere behind her, thin and distant, like a radio left on in another house. Ahead of her, Richmond Park lay flat and black and enormous. She'd walked this route in daylight twice. Both times it had taken eighteen minutes from the wall to the standing stones. Both times there had been deer — great tawny shapes moving through the grass with the unbothered arrogance of things that had never been hunted. There were no deer tonight. Rory noticed it the way you notice a missing tooth with your tongue: not immediately, and then constantly. The park should have been full of small noises. Bracken shifting. The dry cough of a stag. A wood pigeon resettling itself in the crown of an oak. Instead there was her own breath, and the suck of her boots in the mud, and beneath both of those a silence so complete it had texture, like a hand cupped over her ear. Fine, she thought. Fine. Deer sleep. Birds sleep. Everything sleeps except idiots on errands. She put her hand inside her jacket and closed it around the pendant. The Heartstone was warm. Not hot — warm the way a mug of tea goes when you've forgotten it, that particular fading blood-heat. It had been cool when she left the flat above Silas' bar. Cool on the Tube. Cool going over the wall. Now the little crimson gem sat in her fist like something with a pulse of its own, and she could feel the silver chain sliding against her knuckles. That was the point, she reminded herself. That was the entire point. She'd come out here because the pendant had started doing this on Tuesday and hadn't stopped, and because she was tired of not knowing what she was carrying around her neck, and because Isolde's grove was the only place within forty miles where anyone might give her a straight answer. Rory started walking. The grass grew tall past the first stand of trees, hip-high and pale, seedheads pattering against her thighs. She kept her eyes on the ridge where the oaks stood. Eighteen minutes. She counted her steps for the first hundred and then lost the thread, and when she checked her phone the screen said 11:47, which was what it had said when she went over the wall. She looked at it for a long moment. Then she turned the phone off, put it in her pocket, and did not take it out again. The oaks came into view sooner than they should have. She recognised the shape of them, the way the largest one leaned east with its lowest bough dragging the ground like a broken arm. Nine trees, arranged in no pattern she could name, roots knotted over one another as if they'd been trying to climb out. Between them the air had a faint grain to it, like a photograph enlarged too far. Rory stopped ten feet short. *Something* was different. She stood there in the dark, breathing, cataloguing, because that was what she did — Brendan Carter's daughter, sixteen months of Pre-Law and a lifetime of being told she noticed too much. The stones were right. The lean of the oak was right. The wildflowers were right, and they shouldn't have been in November, blue and white and yellow, glowing very faintly at the edges the way things do when your eyes are adjusting. The wrongness was that the flowers were flat. All of them. Every stem bent the same direction, away from the grove, as though something enormous had walked out through the boundary and pressed the whole clearing down under its weight. And they had stayed pressed. Not one had begun to lift. "Isolde," Rory said. Her voice came out wrong. Too small, too close, like she'd spoken into a coat. She waited. The pendant throbbed once against her sternum, hard enough that she felt it in her teeth, and went hot. Behind her, far back in the grass, something moved. She didn't turn. She'd learned that from Evan, of all people — the useful lessons always came from the worst places. You didn't turn towards a sound; you turned so the sound was on your strong side, and you kept your feet under you. Rory pivoted a quarter-step, slow, and looked at the field from the corner of her eye. The grass was still. Then, forty feet out, a stripe of it went down. A neat line, two feet wide, laid flat as if by a hand drawn across a table. It appeared without sound. It stopped. Rory's mouth had gone completely dry. Another stripe, twenty feet closer. Silent. There should have been a hiss, a rustle, the wet snap of stems — she could hear her own eyelashes when she blinked, she could hear the blood in her ears, and the grass went down without a whisper. "All right," she said, and her voice cracked in the middle of the word. She backed towards the stones. The leaning oak's bough was three steps behind her; she'd counted. Two steps. The heat of the pendant had spread across her chest, a spilled-drink warmth soaking through her shirt, and she thought, absurdly, *it's not warning me about the grove.* *It's warning me about what's between me and the grove.* Because the third stripe of flattened grass was not behind her at all. It was to her left, close enough to see the individual seedheads lying down in it, close enough that if there had been anything standing in it she would have been able to reach out and touch a knee. There was nothing standing in it. Rory looked at that empty pressed-down space, at the shape of it — long, wider at one end, the way a bootprint is wider at the toe — and something in the back of her skull began screaming with great politeness, a rising note like a kettle in another room. The flowers of the grove shifted. All of them at once. Bending further, pressing themselves flatter into the earth, cowering. A sound came out of the dark. It wasn't a growl. It wasn't a voice. It was the sound of a very large animal breathing out through its nose — a single, unhurried exhalation, and it came from directly in front of her, at a height she estimated, before she could stop herself, at somewhere near eight feet. The breath moved her hair. Rory did not scream. She would be proud of that later, in a way that felt like being proud of the arrangement of the deck chairs. What she did was take one step backwards over the oak root, and then another, and the moment her heel came down inside the ring of stones the world changed pitch — the pressure in her ears popped, the silence broke like glass, and suddenly there were crickets, thousands of them, a wall of ordinary noise so loud she flinched. Inside the ring, the wildflowers stood upright. Blue and white and yellow, faintly luminous, perfectly still. Outside the ring, nothing. No flattened grass. No stripes. The field lay smooth and silver all the way back to the treeline, unbroken, undisturbed, as if she had imagined the whole thing. And nine feet from where she stood, just past the boundary, one white flower lay crushed into the mud. While she watched, it lifted itself upright. Rory backed to the centre of the grove, pulled the pendant out of her collar, and held it up. It was glowing — a deep crimson coal, bright enough to throw her own shadow onto the grass behind her — and it was so hot she could smell the leather of her jacket beginning to complain. "Isolde," she said. "*Isolde.* Whatever the rules are, whatever it costs — I need you awake. Right now." The crickets stopped. All of them. Mid-note. And in that beautiful, terrible quiet, from somewhere just outside the stones, something very patient began to walk a slow circle around the grove.
