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 pendant had gone cold against Rory's sternum an hour ago, and it stayed cold. She told herself this meant nothing. She told herself a great many things as she pushed through the final curtain of willow branches and stepped into the clearing. The Fae Grove did not look like Richmond Park. That was the first wrongness, though she would not name it as such. The grass here was too green, the color of old bruises healing wrong. Wildflowers crowded the periphery of the standing stones—foxgloves and bluebells and something with petals like torn silk, all blooming in defiance of the October dark. No wind moved through them. They simply stood, heavy with impossible color, and watched. Rory had come here for the stones. Eva had described them once, drunk and laughing at three in the morning, before the call from Cardiff had come and Eva had stopped answering her phone. *Ancient oak standing stones*, Eva had said. *Mark the boundary. Time moves different there. An hour inside can be minutes or days outside.* She had meant it as a joke. Or a warning. Rory could no longer remember which. She had come because the dreams had started. Three nights now of the same vision: a door made of woven branches, opening onto a corridor of faces she almost recognized, and a voice that was not a voice saying *you left something behind, you left something behind, you left something behind* until she woke with her wrists aching and the crescent scar on her left wrist burning like a brand. The pendant had been warm when she left the flat above Silas' bar. She had felt its pulse against her collarbone as she cycled through the park gates, past the deer that stood too still in the dark, past the lampposts that flickered in a rhythm almost like breathing. Warm, then cooling, then cold. She had not thought to turn back. Now she stood in the center of the grove, and the stones were wrong too. Eva had said oak. These were oak, yes, but wrong—the bark too smooth, the grain running in spirals that made her eyes slip sideways if she looked too long. They formed a circle, seven stones, and in the center of the circle the grass had been worn to bare earth in a perfect ring, as if something heavy had stood there for a very long time. Or as if something still stood there, just not where her eyes could track it. Rory's phone showed 11:47 PM. She checked it again. 11:47 PM. She checked a third time. 11:47 PM. She laughed. The sound came out too loud in the stillness, and the wildflowers did not move, but something in the dark beyond them did. A shift. A weight redistributing itself. She told herself it was a deer. Richmond Park was full of deer. They were everywhere, stupid and fearless, and one of them had probably wandered into the grove and was watching her with eyes that caught no light. "Hello?" Her voice cracked. She cleared her throat. "Hello? I'm not—I'm not trespassing. I just need to—" The words died. Because the ring of bare earth in the center of the stones was no longer empty. Something had risen from it, or something had been waiting beneath it, and it was standing now where the grass had been worn smooth, and it was wearing the shape of a person but wrong in the way that dreams are wrong, in the way that the space between lightning and thunder is wrong—occupied by something that should not exist. Rory's hand went to her wrist. The scar there was burning. The pendant against her sternum was ice. The thing in the center of the stones did not have a face. Or rather, it had too many faces, or the suggestion of faces, features that slid and rearranged themselves when she tried to fix her gaze upon them. It wore no clothes. Its skin, if it was skin, was the color of the inside of an eyelid, translucent and veined with something that pulsed too slowly, too deliberately. It stood on legs that bent the wrong way, joints folding backward like a spider's, and it did not move, but Rory felt the movement anyway, felt the air in the grove rearrange itself around its stillness as if the world were holding its breath. She should run. Every instinct she had, every fiber of the quick-thinking, out-of-the-box mind that had gotten her through Cardiff Law and abusive Evan and the slow collapse of her life in Wales, screamed at her to run. But her feet would not move. The cold from the pendant had spread, she realized. It had spread through her chest, down her arms, into her fingertips. She was freezing. She was always freezing, in this place, and the thing in the stones was the only warmth, the only— No. She thought of Eva's voice, three in the morning, *time moves different there*. She thought of the dreams, the door, the voice that was not a voice. She thought of Evan, who had loved her with a love that left bruises, who had told her she was nothing, she was nothing, she was nothing until she had believed him enough to leave. The thing in the stones took a step. The bare earth did not show a footprint. The grass did not bend. Rory found her voice. It came out as a whisper, then a rasp, then something almost human. "I didn't leave anything. I took everything. I took—" She stopped. She did not know what she had taken. She only knew that she had run, that she had run so fast and so far that she had ended up here, in this impossible place, with this impossible thing wearing the shape of a person and wearing her mother's face for just a moment, just long enough to make her heart stutter, wearing Eva's face, wearing her own face with the eyes wrong, the mouth too wide, smiling with teeth that were not teeth. The pendant burned. Not warmed—burned. A sharp, clean pain against her sternum, and Rory gasped and the cold in her limbs broke like ice on a river, and she could move, she could *move*, and she ran. She ran toward the willow branches, toward the curtain of leaves that had been her entrance, and behind her the thing in the stones did not follow. It did not need to. It was already in the grove with her, had always been in the grove with her, was the grove, was the wrongness in the grass and the stillness of the flowers and the way the standing stones spiraled like something growing, something *hungry*— The willow branches were not there. She had run through them, she was certain, she had felt them brush her face, her shoulders, the back of her neck, and now she stood in darkness and the branches were gone and the stones were gone and the flowers were gone and there was only the corridor from her dreams, the corridor of faces she almost recognized, and the door at the end of it opening onto— She woke on the bare earth in the center of the stones. The wildflowers were still there, still blooming, still not moving. The standing stones spiraled above her. Her phone showed 11:47 PM. The pendant against her sternum was warm again, pulsing faintly, almost gently, like a heartbeat. Rory lay very still. She did not check the time again. She did not look for the thing that had worn her mother's face, or Eva's, or her own. She lay in the center of the grove and she breathed, and she waited for dawn, and she told herself that dawn would come, that time moved differently here but it still moved, that an hour inside could be minutes or days outside and she would take minutes, she would take seconds, she would take whatever the grove would give her as long as it was *outside*, as long as it was *away*, as long as it was not here in the dark with the stones watching and the flowers not moving and the cold creeping back into her chest from the pendant that had betrayed her, that had led her here, that had— She closed her eyes. The scar on her wrist was burning. In the dark, she could almost hear it, the voice that was not a voice, saying *you left something behind, you left something behind*, and she understood, finally, what it meant. She had left herself. She had left the girl who believed in things, who laughed at three in the morning with Eva and thought the world was wide and strange and *hers* for the taking. She had left that girl in Cardiff, in London, in the flat above Silas' bar, in every version of herself that had ever thought she could outrun what was inside her. The grove did not answer. The grove never answered. It only waited, patient and ancient and hungry, for her to open her eyes and see that the stones had moved, that the circle was smaller now, that the bare earth was closer, that the thing wearing her face was standing over her with its too-many features sliding into something almost like love, almost like recognition, almost like— Rory opened her eyes. The wildflowers were watching. The stones were watching. The dark beyond the grove was watching, and in that dark, at the very edge of her vision, something that had been waiting since before the oak grew, since before the first human walked into this clearing and felt the wrongness and ran and never found their way back, something that wore no face because it had collected all of them, all the faces of all the someones who had come here looking for something they had lost— It smiled with her mouth. And Rory, who was cool-headed and intelligent and known for quick out-of-the-box thinking, found that she had no thoughts left at all, only the cold spreading from the pendant, only the warmth of the thing bending over her, only the terrible, perfect certainty that she was not alone, that she had never been alone, that the grove had been waiting for her since before she was born, since before her mother was born, since before the stones were stones at all and the world was young and the boundaries between here and there were thin enough to walk through, thin enough to— The pendant pulsed once, twice, three times. And went dark.
