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 note had come two nights ago, folded into a bag of mixed starters from the Golden Empress, written in a hand too neat to be Yu-Fei's: *The grove remembers. Come alone. When the stone warms, you'll find the door.* Rory had almost thrown it away. Then the pendant had started to pulse. It was pulsing now, a faint rhythmic warmth against her sternum, patient as a second heartbeat, and it had grown warmer with every step she took into Richmond Park. Just before midnight she had let herself through the gate with the key she wasn't supposed to have, and now she was deep in the dark of the park's interior, following a stone the size of a thumbnail the way sailors once followed stars. Frost silvered the bracken. Her breath hung in front of her and unraveled. Somewhere behind her, London was still making its low continuous noise — traffic, a distant siren, the hum of a city that never quite slept — but the sound thinned with every hundred yards, the way a radio fades when you drive out of range, until all she could hear was her own boots and, faintly, wind moving in the canopy high above. That was the first wrong thing, though she didn't register it as one yet: no birds. No deer. Richmond Park was never truly empty — the herds were always somewhere, breath steaming, hooves ticking against the frozen ground — but the bracken stood untouched, the paths unmarked, as if everything alive had quietly agreed to be elsewhere tonight. The pendant gave a stronger pulse, and Rory stopped. She had walked past this stretch of woodland a dozen times in daylight. There was no path here, no clearing. But the trees had opened ahead of her the way a crowd opens, and between two massive trunks she could see frost-white grass, and colour — impossible, startling colour, reds and blues and yellows burning against the November dark like a scrap of summer dropped on the ground. She stood at the edge for a long moment, weighing it. She was, by general agreement of everyone who knew her, the calm one. The one who thought fastest when things went sideways. Evan had taught her that in the worst possible way — how to keep her voice level, her mind working, while everything around her was going wrong. She owed him that, at least. "Right," she said quietly, to herself, to the night. "Right." She went in. The stones were waiting for her. There were eleven of them, arranged in a loose ring, and they were wrong in a way her brain took a moment to name: they were stone, unmistakably stone, but the grain of them ran in long vertical sweeps, and there were places where the surface still held the pattern of bark. Oaks, she thought. Oaks that had stood here once, centuries ago, and been taken by the stone the way amber takes an insect. They rose taller than any man, and the frost on them did not melt. And the flowers. Poppies, months dead everywhere else in England. Ox-eye daisies. Cornflowers blue as her own eyes. Red campion nodding on stems that should have rotted in September. They grew in careless abundance across the whole clearing, and the smell of them was sweet — too sweet, sweetness with a rotten edge underneath, like fruit kept past its time. The wind she'd heard in the canopy did not reach here. Inside the ring, the air was utterly still, and utterly silent, and Rory noticed that her breath made no sound. She breathed out, hard, deliberately. Nothing. Her pulse picked up, and the pendant pulsed with it, warm against her skin, and then — this was the moment the wrongness stopped being deniable — it pulsed once, alone, without her. Something under the ground had a heartbeat. The stone was only repeating it. "Hello?" Her voice came out flat and dead in the still air, swallowed instantly, as if the grove ate sound the moment it left her mouth. She made herself walk the inside of the ring, cataloguing the stones, looking for the door the note had promised, and it was somewhere on her third circuit that she heard the footstep. Not hers. Hers — but a half-beat late. The crunch of frost, just behind her left shoulder, arriving a fraction after her own boot came down, the way an echo arrives. She stopped. It stopped. She waited, counting her own heartbeat, and heard nothing at all. She turned. The clearing was empty. Flowers to the stones, stones to the flowers. Nothing between. She turned back, took three steps, and on the third step there it was again — crunch — and then one more, after hers had finished. One extra. Like someone remembering, at the last moment, to add a foot. Rory's mouth went dry. She pulled her phone from her coat. No signal, of course, but the clock read 00:47, which was right, that was fine, she'd checked it at the gate. She put the phone away. Twenty minutes later — it felt like twenty minutes, she had walked the full ring twice — she checked it again and the screen said 02:13. The battery had dropped from seventy percent to nine. The moon, which had been sitting low over the eastern trees when she entered, was now high and wrong, hanging at an angle she couldn't make sense of, as if the sky had been picked up and set back down carelessly. The flowers were facing her. She was almost sure they hadn't been before. Every daisy, every campion, every cornflower in the clearing had turned its face toward the centre of the ring — toward her — the way sunflowers follow the sun, except there was no sun, and she was the only warm thing in the grove. "Rory." Her name came from behind the stones. Soft. Her mother's voice — the Welsh vowels, the way Jennifer Carter said her daughter's name across a kitchen in Cardiff a lifetime ago. Rory's whole body went cold, colder than the night. Her mother was in Cardiff. Her mother had not known where she was in four years. "Rory," the voice said again, and this time it wasn't her mother's. The vowels had shifted mid-word, slid into a different cadence, one she knew in her bones and had spent four years learning not to flinch at. Evan's way of saying it. Amused. Patient. The voice of a man who had never once raised his hand in public. "Who's there?" she said, and hated how thin it came out. Silence. The sweet-rot smell thickened. The pendant was hammering now, hot as a coin left in sunlight, and she could feel its heat spreading into her skin, into the old crescent scar on her wrist, which ached suddenly the way it hadn't since childhood. She looked at the ring of stones, at the gaps between them — and saw them. Figures. In the gaps. One to each gap, eleven of them, standing at the outer edge of the ring where the darkness of the wood began, motionless as the stones themselves. They had not arrived. They had not moved. They had simply, somehow, always been there, and her eyes had only just now agreed to see them. They were too tall and too still and their shapes were almost right, almost human, the way a mask of a face is almost a face. They did not move. That was the worst of it. But the nearest of them was closer than it had been a moment ago, and the one after that closer still, and no amount of staring could catch them in the act of it. And the figure in the gap directly ahead — the one framed between two bark-grained pillars, the one now only twenty feet away — was wearing her coat. Her grey coat, with the torn pocket. Its face was a pale smudge she could not make herself focus on. The pendant went cold. Rory ran. She didn't decide to; her body simply took the decision away from her, and she was sprinting the ring's edge, flowers whipping her ankles, searching for the gap between the trunks she'd entered through — and it wasn't there. Solid oak. She ran on, the stillness behind her absolute, no footsteps now, nothing chasing, which was worse than chasing, and found a gap, threw herself through it— The world snapped. Cold air, real air, wind in the branches, her own breath ragged and loud and gloriously audible. She ran until the trees ended, until frost-crunch became pavement, until she was leaning on the park gate with her lungs burning. Her phone said 04:17. Forty missed messages from Eva. The battery was dead in her hand. The pendant hung cold and dull against her chest, and she almost wept with relief — until she raised her head and caught it on the frost-sharp air, faint and unmistakable: the smell of summer. Of cut grass and daisies. Miles from the grove, in the teeth of November. And far behind her, deep in the park, something said her name. Gently. In her own voice.
