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 gap in the fence near Ham Gate was narrower than Rory remembered. She had to turn sideways and drag her jacket through after her, the wet metal catching on the zipper with a sound too loud for the hour. Richmond Park stretched ahead of her in a wash of black and grey, the trees along the avenue standing like a second, taller fence. No lamps this far in. No traffic noise. Just the damp and the smell of leaf mould and the faint, persistent warmth against her sternum. The Heartstone had been pulling since dusk. Not a tug she could point to on a map, more a pressure behind the ribs, a compass with opinions. Three nights of waking with the crimson stone hot through her shirt. Two days of it leaning northwest whenever she stood still. She had looked up the park on her lunch break, scrolling forums between deliveries, and found a thread that mentioned Isolde's grove before the whole conversation vanished. A clearing that did not appear on any Ordnance Survey sheet. Standing stones. Time that could not be trusted. She had come because ignoring it had stopped being an option. Her torch cut a thin white cone across the grass. She kept it low, more habit than caution; there was no one out here to see her. The deer would have bedded down hours ago. She walked the avenue until the tarmac gave out, then followed the pull off the path, into the bracken, her boots sinking a little with each step. The scar on her left wrist itched. It always did in the cold. She found the stones by nearly walking into one. It rose out of the dark without warning, a weathered upright taller than she was, its surface pitted and pale. Oak, she thought at first, until her palm met it and found rock, not bark. More of them stood in a loose ring beyond it, eight or nine, half-swallowed by the trunks of trees so old their roots had buckled the earth. Between them, a clearing. Wildflowers. White and yellow and a blue so saturated it looked painted, all of them open, all of them facing inward, as if the moon were a sun. It was late October. The rest of the park was a graveyard of leaves. Rory stood at the boundary with the torch beam resting on a clump of something that might have been campion and might not. The Heartstone pulsed once, a slow heat that spread across her chest and faded. She checked her phone. No signal. The time read 11:47. She had left the flat at eleven. The walk from the fence should have taken twenty minutes at most. She stepped between the stones. The air changed. Not warmer, exactly. Thicker. The kind of stillness that sat in churches and empty swimming pools. Her torchlight seemed to stop sooner than it should, as if the dark in here had weight. The wildflowers did not crush under her boots. They bent and sprang back, and the smell of them was wrong, sweet the way rotting fruit is sweet. "Hello?" Her own voice came back at her flattened, without echo. She had not expected an answer. She had come looking for a place, not a person. Still, the silence that followed felt like a held breath. She moved toward the centre of the clearing. The stones were behind her now, and when she glanced over her shoulder they looked closer than they had been. A trick of the torch. She turned a slow circle anyway, counting them. Nine. She counted again. Eight. The ninth was there when she stopped trying to find it, standing a little apart, its face turned toward her in a way stone should not have a face. Rory exhaled through her teeth. Cool head. She had always been good at that. Catalogue what you can see. Do not invent the rest. What she could see: a clearing perhaps thirty metres across. Flowers that did not belong. Stones that would not hold still in her peripheral vision. Ancient oaks packed so tightly at the edge that she could not tell where the grove ended and the park began. No path out except the one she had used, and she was no longer certain which gap that had been. What she could hear: nothing. Then, under the nothing, a sound like fabric dragging over grass. Very faint. Very close. She swung the torch. Empty flowers. Empty dark. The sound stopped the moment the light touched it. The Heartstone pulsed again, stronger. The silver chain was warm enough now that she could feel it against her collarbone. Near a Hel portal, the woman who had given it to her had said, though there had been no woman, not really, only a parcel on the mat and a note in handwriting she did not recognise. Pulses faintly with warmth. Faintly. This was not faint. Rory thumbed the torch to a wider beam and started back toward the stones. She would leave, go home, try again in daylight like a person with sense. The gap she had entered by was not where she had left it. She walked the ring. Nine stones. Eight. A tree where a stone had been. A stone where she was certain there had been a gap. The dragging sound started again, off to her left, and this time it did not stop when she looked. It had rhythm. Not footsteps. Something being pulled. Or pulling itself. She kept walking. Her pulse was up but her hands were steady; she had learned, after Evan, how to put fear in a box and keep moving. The box was getting full. At the far side of the ring she found a space between two oaks wide enough to squeeze through, and she did, branches scraping her hair, and came out into the same clearing. The same flowers. The same stones, watching. Rory stood very still. The moon had been low and yellow when she entered the park. It sat now almost overhead, a hard white coin, and the shadows it threw were too long, stretching from the stones like fingers toward the centre where she stood. She looked at her phone. 11:51. Four minutes. The moon did not move like that in four minutes. A laugh came from the trees. Not a child's, not quite. Too even. It ran along a scale that human throats did not use and cut off as if a hand had closed over a mouth. Rory turned the torch toward it and caught, at the very edge of the light, a pale shape that folded itself behind a trunk. Too tall. The proportions wrong in a way she could not name until she realised it had been bending at places that were not joints. She did not call out again. The flowers nearest her feet had turned. Not all of them. A cluster of the blue ones, their faces lifted, tracking her the way sunflowers track the sun. She took a step left. They followed. She took a step back. They followed. When she shone the torch directly on them they were only flowers, stems and petals, nothing behind the colour. She switched the torch off. In the moonlight the grove was a different place. Greys and silvers. The stones looked like a circle of old women. The oaks leaned in. And at the treeline, in the places the moon did not reach, things shifted. Not coming forward. Arranging themselves. As if they had been waiting for her to stop making so much light. The Heartstone was hot enough to hurt. She pulled it out from under her shirt, the deep crimson gem sitting in her palm like a coal, a faint inner glow visible even against the moon. It beat. Once. Twice. In time with something that was not her heart. Breathing. Behind her. Slow and wet and close enough that she should have felt it on her neck. Rory turned. Nothing. The centre of the clearing was empty. The flowers lay still. But the grass where she had not walked was pressed down in a line, a trail that started at the stones and ended one pace from her heels. She had been followed in. Or something had been here already, and had come to stand where she stood. Another sound, this one from above. A creak of wood. She looked up into the canopy and saw branches that did not move with any wind, because there was no wind, and among them a density that was not leaves. It had a head, or the idea of a head. It did not look down at her. It did not need to. She felt the attention like a hand on the back of her skull, heavy and interested and patient. Rory put the pendant back against her skin and started walking, not toward the stones this time but across the clearing in a straight line, torch on, beam held out like a blade. If the grove was a pocket, if the stories were even half true, then a boundary had two sides. She would find the other one. She would not run. Running told whatever was in here that she agreed it was a predator. The dragging started up on her right, matching her pace. When she slowed, it slowed. When she stopped, it stopped, and in the silence she heard it breathe again, a little faster now, as if the matching had been work. She did not look. Looking had not helped. She kept her eyes on the far stones and her feet moving, and the wildflowers leaned out of her way as if they had been told to. A whisper, at her left shoulder. Not words. The shape of words, the rhythm of English without the meaning, the way a recording sounds when it has been stretched. Her name was in it. Not Rory. Aurora. Then Laila, which no one in London called her. Then something else, a longer name that sat in her mouth like a stone when she almost repeated it, Malphora, and she did not know why she knew it was hers. She reached the stones. They were closer together than they had been. She had to turn sideways, the same as the fence, stone scraping her jacket, and for a moment she was in a gap that went on too long, a corridor of rock and root with no end, the torch showing her only more of the same. The heat of the pendant became a spike of pain. She shoved through. Richmond Park. The avenue. The wet grass. The moon low and yellow where it belonged. Her phone said 11:49. Rory stood with her hands on her knees and did not look behind her. The fence was a ten-minute walk if she did not run. She could hear, very faintly, from a direction that was no longer a direction, the dragging sound as it lost her trail and began, slowly, to search. The Heartstone cooled against her chest, pulse by pulse, until it was only a stone again, thumbnail-small, deep crimson, ordinary as a lie. She walked. She did not run. At the gap in the fence she paused, one hand on the metal, and the scar on her wrist burned as if something on the other side of the night had reached through and pressed a thumb there, just to let her know it had her measure. The park was empty. The park had always been empty. She told herself that all the way back to the road, and the telling did not make it true.
