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 hedge had snagged her jacket twice already, thorns pulling at the cheap nylon as Rory forced her way through the gap near Richmond Park's southern boundary. The gates had locked at dusk. She had known they would. She had come anyway. The Heartstone sat against her sternum, a thumbnail of deep crimson on its silver chain, and it had been warm since the sun went down. Not the residual heat of her skin. A pulse. Faint, rhythmic, like something alive and impatient. It had never done that in the flat above Silas's bar, never on her delivery routes through Soho, never once in the two years since it had arrived in a plain envelope with no return address. Tonight it had pulled. She had followed. Frost silvered the grass beyond the hedge. London's sodium glow faded behind her as she moved deeper, the park swallowing sound the way deep water swallowed light. Her breath fogged. She kept her hands in her pockets, one thumb worrying the crescent scar on her left wrist, an old habit from childhood that still surfaced when her thoughts ran too fast. Cool-headed, people called her. Quick. Out-of-the-box. She told herself this was just that: following a lead, testing a theory. The pendant came from somewhere. Dymas, the note had said, in a handwriting she did not recognize. She had spent weeks in the British Library's restricted stacks after that, chasing references that led, eventually, here. A hidden clearing. Standing stones. A place that was not quite on any map. She found the oaks first. They rose without warning, a ring of them, trunks thicker than her outstretched arms, bark ridged like old scars. Between them stood the stones: weathered, taller than she was, their surfaces pitted and dark. Ancient oak standing stones, the texts had called them, though she still was not certain whether that meant the trees or the megaliths or both. They marked a boundary. She felt it the moment she stepped between two of them, a pressure change in her ears, a sudden thickness to the air. The frost vanished. Wildflowers carpeted the ground inside the ring, white and violet and a yellow so bright it seemed to hold its own light, blooming as if it were midsummer instead of whatever month this actually was. She had lost track. The park had been winter-bare five minutes ago. Rory stopped. The silence was wrong. Not the ordinary quiet of a locked park at night, with its distant traffic murmur and the occasional fox scream. This was absence. No wind in the leaves, though the oaks should have been stirring. No insects. Her own footsteps on the flower-choked earth sounded muffled, as if the ground itself were absorbing them. She turned a slow circle. The stones stood where they had stood. The trees did not move. Yet the back of her neck prickled, that old animal knowledge that something had shifted just beyond the reach of her eyes. She unclipped her phone. No signal. The time read 11:47. She was certain she had entered the park closer to ten. An hour inside can be minutes or days outside, one of the more unreliable sources had claimed. She had dismissed it as folklore. She did not dismiss it now. The Heartstone pulsed again, warmer. She pulled it from her collar. The gem's inner glow was faint, a banked coal, but it was there. Near a Hel portal, the same unsigned note had said. She had not known what that meant. She still did not. The air smelled of crushed petals and something underneath, metallic and sweet, like blood left too long in the sun. She told herself it was the flowers. A sound. Not behind her. Not ahead. Somewhere to the left, low among the stones: a rustle, too deliberate for wind, too slow for an animal. She turned her head without moving her feet. Nothing. The wildflowers nodded, though there was still no breeze. She took three steps toward the nearest stone. Its surface was colder than the night air, slick under her palm. Carvings, almost worn away, spiraled across it. She leaned closer. They were not spirals. They were faces, or the suggestion of faces, mouths open in shapes that might have been singing or screaming. She pulled her hand back. Another rustle. Closer. Rory straightened. Her voice, when she used it, came out steady. "I know you're there." No answer. Of course there was no answer. She was talking to trees. She was a grown woman who had fled Cardiff and an abusive ex and a life that had been mapped out for her, and she was standing in a park after midnight talking to trees because a piece of jewelry had gotten warm. She almost laughed. The sound died in her throat. Something moved at the edge of her vision. She snapped her head toward it. A pale shape, tall and thin, had been standing between two oaks. It was not there when she looked directly. Only the trees, the stones, the impossible flowers. She held still, counting her breaths. In. Out. The Heartstone's pulse matched them now, or she was matching it. She could not tell which. When she looked again, carefully, from the corner of her eye, the shape was back. It had no features she could name. It had the suggestion of shoulders, the suggestion of a head tilted as if listening. It did not approach. It watched. She took a step backward. The flowers crushed under her boot with a wet sound that was too loud. The shape did not follow. It simply was not there anymore when she blinked. Rory's pulse was up now, a hard knock in her throat. She was not given to panic. She had walked away from Evan with a split lip and a suitcase and a plan, had rebuilt a life in a city that did not care who she had been. This was different. This was the certainty, settling into her bones like cold, that she had not arrived alone and would not leave that way. She turned toward the gap in the stones she had entered by. It was gone. The ring was complete. Eight stones, eight oaks, no opening. She walked the circumference anyway, one hand trailing the bark, the other clenched around the pendant. The silver chain bit into her palm. The gem's glow had strengthened, throwing a faint red wash across her fingers. Her shadow stretched ahead of her, then lagged, then stretched again, as if it could not decide which direction the light was coming from. She stopped walking. Her shadow took one extra step before it froze. A child's laugh drifted across the clearing. High, bright, utterly out of place. It came from everywhere and nowhere, bouncing between the stones until it frayed into something that was not quite laughter anymore. Rory's mouth went dry. She thought of Eva, of summers in Cardiff when they had been small enough to believe in hidden places. She thought of the name Laila, the one she had used for six months after leaving Wales, the one no one in London knew. The laugh did not sound like Eva. It did not sound like a child, not really, not once it had finished echoing. "Who's there?" Her own voice came back to her a half-second too late, and not quite in her pitch. As if the grove had recorded it, considered it, and played a slightly wrong version. She swallowed. The flowers at her feet had turned. Every bloom in the clearing now faced her, pale faces on thin stems, tracking her the way sunflowers tracked the sun. She had not seen them move. They were simply oriented, all of them, toward her. She crouched, slowly, and touched one. The petals were cold. They closed around her fingertip with a softness that felt like a mouth. She yanked her hand back. No mark. No blood. Only the lingering impression of something that had wanted to keep her. The rustling started again, this time from three directions at once. Not animals. Not wind. The sound of cloth, or of dry leaves being rubbed together in a rhythm that almost matched a walk. Footsteps that were not hers, circling just outside the ring of stones, never quite entering, never quite leaving. She stood. She turned with them, trying to keep whatever it was in front of her. Her black hair stuck to her neck. She had not realized she was sweating. A figure resolved at the far side of the clearing. Not the pale suggestion from before. This one had more substance, though the details refused to hold. It was roughly her height. It wore something that might have been a coat, or might have been bark. Its face was a smear of shadow except for the eyes, which caught the Heartstone's glow and threw it back, two points of dull red. It did not speak. It did not need to. The certainty that had been building since she stepped between the stones crystallized: she had been expected. The pendant had not led her here by accident. Something had wanted her to come, and she had obliged, because she was intelligent and curious and had spent her whole life believing she could think her way out of anything. The figure lifted one hand. Rory did not wait to see what it held. She ran. The clearing was not large. It should have taken seconds to cross. She ran and the stones receded, the oaks stretching taller, the flowers blurring underfoot into a carpet that grabbed at her ankles. Her breath tore. The Heartstone burned now, not warm but hot, a brand against her chest. Behind her the footsteps matched hers exactly, no longer circling, no longer pretending. They were close enough that she could hear the pause between them, the wet give of earth that was not quite earth. She did not look back. The laugh came again, no longer a child's, no longer anything that belonged in a throat. It filled the space between the stones until there was no space left. Rory's blue eyes streamed. She did not know if it was the cold or the flowers' scent, that sweet-metallic reek that had grown stronger, coating her tongue. She reached the place where the gap should have been. Her hands found stone. Solid. Unbroken. She slammed her palm against it and the carvings shifted under her skin, the worn mouths opening wider. The footsteps stopped. Directly behind her. She could feel it, the displacement of air, the attention like a weight between her shoulder blades. She did not turn. She pressed her forehead to the stone and listened to her own heartbeat and the pendant's pulse and the third rhythm that had joined them, slow and patient, close enough to touch. The wildflowers at her feet had closed again, all of them, as if they had seen enough. A voice, when it came, was almost kind. It used her name. Not Rory. Not Aurora. The one from the envelope, the one she had never spoken aloud. The stone under her hands was no longer cold.
