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 Heartstone had been warm since Westminster. By the time Aurora reached the southern edge of Richmond Park, it burned against her sternum like a held coal, pulsing in a rhythm that was not quite her own heartbeat. She had followed it the way she followed street names on a delivery run: one turn, then the next, no argument with the destination. The park gates had been locked since dusk. The gap in the hedge was narrow enough that the hawthorn scored her jacket as she pushed through. She did not look back at the road. Frost silvered the grass. Her breath smoked. The pendant’s faint inner glow leaked through the wool of her jumper, a deep crimson thumbnail that made the dark around it look thicker, as if the light were drinking rather than giving. She kept one hand over it as she walked, not for comfort, exactly, but because the warmth had a direction now, a tug that pulled her northwest, away from the paths, into the older trees. Richmond Park at night was supposed to be empty in a particular way: deer, wind, the distant wash of traffic. This emptiness was wrong. The traffic had fallen off as if someone had closed a door. The wind did not move the high branches. Her boots made sound, but the sound died too quickly, swallowed before it could travel. Aurora counted her steps without meaning to. She had always counted when something in her refused to name itself. The standing stones announced themselves as a change in the air before she saw them. Oak, ancient, taller than she had expected, arranged in a rough ring that the maps did not mention. Moss blackened their bases. Their faces were not carved, not quite, but the grain of the wood ran in patterns that suggested mouths if she looked too long. Wildflowers crowded the ground inside the ring, pale in the dark, blooming as if it were June. It was January. She knew it was January. Her breath still smoked. She stopped at the boundary. The pendant surged, a single hard pulse that made her flinch. The crescent scar on her left wrist itched, a childhood accident she never thought about, suddenly loud under the skin. Aurora Carter did not believe in omens. She believed in patterns, in the difference between a locked door and a door that only looked locked. She stepped between the stones. The temperature rose. Not warmth, exactly. A thickness, like walking into a room where too many people had been breathing. The wildflowers did not crush under her boots. They bent and sprang back, and the smell of them was sweet in a way that caught at the back of her throat, green and overripe at once. Above, the sky had too many stars, or the wrong ones. She tipped her head and could not find the Plough. Her phone, when she checked it, showed no signal and a time that had not moved since she left the hedge. 11:47. She had walked for twenty minutes at least. She put the phone away. Cool-headed, Eva used to say, like it was a compliment and a warning. Think around the problem. The problem was a grove that did not exist on any map she trusted, a pendant given to her by no one she could name, and a January night full of flowers. The problem was that she had come here because the dreams had started showing her this exact ring of oak, and because doing nothing had begun to feel like the more dangerous choice. Something moved at the edge of her left eye. Aurora turned. Nothing. The trees stood as trees stood. She waited, counting again, and the movement came once more, farther out, a pale suggestion of height that was gone when her gaze arrived. Not a deer. Deer did not hold still like that, and deer did not occupy the exact height of a person. She did not call out. Calling out was for people who wanted to be answered. She walked to the centre of the clearing because the pendant wanted the centre, and because standing at the edge had begun to feel like lingering on a threshold with the door already open behind her. The flowers brushed her calves. Some of them, she realised, were turning. Not in the wind. There was no wind. Their faces — and they had faces, or the idea of faces, pale discs that tracked — followed her the way sunflowers followed light. She looked down at one and it was only a flower again, white petals, yellow throat. She looked away and felt it turn. A sound started that should not have been there. Not footsteps. Not yet. A thin, high note, as if someone were drawing a wet finger around the rim of a glass, far off and then closer, with no sense of travel in between. It came from the stones. Or from inside the stones. Aurora’s jaw tightened. She had heard glass sung in a bar once, Silas showing off to a drunk who would not leave. This was that sound stripped of the bar, of the joke, of the human hand. It braided with a second note, lower, and then a third that might have been a voice if a voice could be played instead of spoken. She said, quietly, “That’s enough.” The notes did not stop. They found a harmony that made the bones behind her ears ache. The pendant’s glow brightened, then dimmed, then brightened again, out of time with the music, as if two clocks were arguing. Aurora turned a slow circle. The standing oaks had not moved. She was certain they had not moved. Their positions were wrong anyway, closer together than when she had entered, the gaps between them narrower. She could still see the park beyond — frost, distant trunks, the idea of a path — but the view had the quality of a painting hung too far back in a room. Another movement. Right side this time, and lower, as if whatever it was had crouched. She did not snap her head toward it. She let her eyes slide, the way she had learned to watch a street without looking like she was watching. For a fragment of a second there was a shape between two trees: the suggestion of shoulders, of hair as dark as her own, of a face that was not a face so much as a pale interruption. Then only trunks, and the flowers, and the frost that did not reach inside the ring. Her own breath was too loud. She held it. In the held silence she heard a second breath, slower, drawn in through something that was not quite a mouth. It came from behind her and from no particular place, a sound with no source she could point to. Aurora let her own air out very carefully and did not hold it again. Panic was a luxury. She had left Cardiff with nothing but a bag and the knowledge that waiting for a thing to become obvious was how you got hurt. This was already obvious. She was not alone. The music stopped as if cut. In the new quiet, something walked. Soft, unhurried, circling the outside of the stone ring. Not hiding. Not rushing. The tread was wrong for boots and wrong for bare feet; it had a slight drag, a wetness, as if the walker moved through a depth of leaves that were not there. Aurora tracked it by ear, turning as it turned, keeping the centre at her back. The pendant had gone from warm to hot to a temperature that was almost cold, a confusion of sensation that made her want to tear it off. She did not. She had the unreasoned conviction that taking it off would be the same as putting down a light in a cellar. “I know you’re there,” she said. Her voice sounded like itself, which somehow made it worse. “I’m not here to trespass. I followed this.” She touched the chain at her throat. “If you want it, you can say so.” No answer. The walking continued, one full circuit, then a second that was tighter, as if the thing had stepped inside the ring without crossing any space she could see. The flowers shivered in a wave that ran toward her and then away. Aurora’s bright blue eyes had always been good in the dark; she used them now and saw, at last, a figure standing between two of the oaks. It had her height. It had her hair, straight and black to the shoulders. It wore a jacket like hers. It did not have her face. The place where a face should have been was smooth and faintly luminous, the colour of the wildflowers, and as she stared the luminosity gathered into the idea of features without committing to them: a mouth that was a line, eyes that were only darker patches. It stood very still, the way she was standing still. When she shifted her weight, it shifted, a half-second late, a mirror with a stammer. Aurora did not run. Running would mean turning her back. She took one step to the side. The figure took one step, late. She took another, toward the gap she had entered by. The figure did not block her. It only matched her, always delayed, always wrong, and as she moved she understood that there were more than one — no, not more. The same one, occupying the edge of vision in three places at once, a stutter of herself stationed at the boundary as if the grove were trying on her shape to see if it fit. The time on her phone, when she risked a glance, was 11:47. Her hands were cold. The scar on her wrist had gone from an itch to a thin, precise ache, as if something were pressing on the memory of the cut. She reached the stones. The gap was narrower than her shoulders. She turned sideways, the way she had come through the hedge, and the oak on her left was warm, almost skin-warm, and it breathed. Not a metaphor. The wood swelled and eased against her arm, a slow inhale, and from somewhere above her head, from the place a mouth would be if the grain were a face, came a sound that was almost her name, almost Rory, almost Laila, almost something older that her bones knew and her mind did not. She shoved through. The park beyond was not the park. The frost was gone. The trees were denser, their trunks pale, and the sky had no stars at all, only a low, even grey that was not cloud. Behind her the standing stones were still there, but when she looked at the clearing the flowers had closed, every one of them, and the figure that was not her stood in the centre with its blank face turned toward the place she had been. It raised a hand. The gesture was hers, the way she lifted a palm to refuse a drink, to hail a cab, to say wait. The pendant gave one last pulse, deep and slow, and then went as cold as a stone in a river. Aurora did not wait to see if the hand would drop. She walked. The grey light did not change. Her footsteps, after a dozen paces, were joined by another set, perfectly matched, coming from directly behind her, so close that if she stopped they would walk into her back. She did not stop. She did not turn. The wrongness had finished building. It had arrived, and it was keeping step, and the grove — Isolde’s grove, Richmond grove, the pocket that was not quite Earth — had decided she was not a visitor after all. Somewhere far off, or very near, a child laughed once, bright and brief, and was cut off as if a hand had closed over a mouth that was not a child’s. Aurora kept walking, eyes forward, the Heartstone a dead weight at her throat, and counted her steps because counting was the only pattern she had left that still belonged to her.
