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 oaks marked the boundary the way headstones mark a grave, and Rory had always thought that a strange thing to notice, but she noticed it again tonight, walking the gravel path with her breath fogging white ahead of her. Richmond Park at midnight should have been empty in the ordinary way parks are empty — deserted, quiet, faintly menacing because of what a person's imagination could do with shadow and wind. This was a different kind of empty. The kind that felt considered. She had the pendant out before she reached the standing stones, holding it in her fist the way she might hold a coin she meant to flip, and even through her glove she could feel the warmth of it, faint but unmistakable, like a coal banked under ash. It hadn't done that on the walk over. It was doing it now. "That's new," she said aloud, mostly to hear her own voice, and then wished she hadn't, because the words didn't echo the way they should have. They just stopped, swallowed somewhere past her lips, as though the air itself had no interest in carrying them further. She'd come because Eva had asked her to — a stupid errand, really, checking on a supply drop that some contact of a contact had left near the grove, something about salt and iron filings that the old woman at the shop in Kingston swore by. Rory hadn't believed in any of it a year ago. She believed in it now the way she believed in gravity: not because she wanted to, but because she'd tested it and it held. The grove itself lay beyond the oaks, past the place where the park's tended grass gave way to something wilder, tangled, unkempt in a way the Royal Parks groundskeepers would never have allowed. She stepped between two of the standing stones — old oak, black with age, carved with symbols she couldn't read but had started, somehow, to feel — and the temperature dropped, not sharply but gradually, the way a held breath grows cold in the lungs. Wildflowers. That was the first wrong thing, properly wrong, not just uneasy-wrong. In November. Bluebells and something like foxglove, pale and nodding in a wind she couldn't feel on her own skin, growing up through frost-killed grass as if the two seasons had simply agreed to share the same six feet of earth. She'd seen it before, knew the grove ran on its own clock, but knowing a thing and standing in the middle of it at night were not the same experience at all. The package was supposed to be near the old fallen beech at the clearing's western edge. She headed that way, gravel giving way to soft moss underfoot, and it was only after a dozen steps that she realized she couldn't hear her own footsteps anymore. Not muffled. Absent. She stopped walking to test it, and the silence that followed was somehow worse than the silence that had come before, because it meant the quiet wasn't a quality of the ground. It was a quality of something listening. "Right," she muttered, and made herself keep moving. The beech was where she remembered it, pale wood split and rotting, and half-buried beneath its roots was a small oilcloth bundle exactly where Eva's contact had promised. Rory crouched to pick it up, and that was when she heard it — not a sound exactly, more the suggestion of one, off to her left, at the very edge of where the moonlight gave out. A dry rustle, like a hand dragged slowly through dead leaves. She looked. Nothing. Just the dark mass of a hawthorn hedge, its shape indistinct, its shadow somehow deeper than shadows had any right to be. She told herself: fox. Deer. Something with a heartbeat and a reason to be here that had nothing to do with her. She straightened, bundle in hand, and the pendant pulsed hard against her palm, a full throb of heat that made her hiss and nearly drop it. She looked down. The crimson stone was glowing now, properly glowing, a dull inner light like a coal breathed on, and when she looked up again the hawthorn hedge had moved. Not blown. Not shifted in wind. Moved, the whole black mass of it three feet closer to where she stood than it had been a moment before, and utterly still now, as if it had simply always occupied that spot and her memory of its former position was the thing at fault. "Okay," she said softly. "Okay, that's — okay." She began walking backward, toward the stones, because turning her back on the hedge felt like the one thing she absolutely could not do, and as she retreated she became aware, with the slow dawning horror of a puzzle piece sliding into place, that the wildflowers between her and the boundary were bent. All of them. Bent inward, toward her, toward the path she'd have to walk, as though something considerably larger than wind had passed through recently and left the grass leaning in memory of its shape. The rustling came again, closer this time, from a direction she couldn't pin down, and beneath it — so faint she might have invented it, might still be inventing it now, telling herself later it was only nerves — she heard breathing. Not her own. Slow, and patient, and entirely uninterested in disguising itself as anything else. She didn't run. Running, she'd learned somewhere in the last year, was an invitation. She walked, quickly, the bundle clutched to her chest and the pendant blazing hot enough now that she could feel it through wool and cotton both, and she did not look at the hawthorn hedge again, and she did not look at whatever else might be moving at the corners of her vision, the pale shapes that weren't flowers, the low shapes that weren't stones. She fixed her eyes on the black oak pillars ahead and counted her own steps because numbers, at least, still meant what they were supposed to mean. Eleven. Twelve. Thirteen. She passed between the stones and the sound of the world came rushing back all at once — a car somewhere on the far road, wind in ordinary trees, her own footsteps loud and mundane on the gravel — and only then did she let herself run the last hundred yards to the gate, the pendant cooling against her chest like something going, gratefully, back to sleep.
