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 path through Richmond Park had been ordinary enough until the oaks changed. Aurora kept her torch low and her steps measured, the way she walked the late streets after a delivery run when the pavements went quiet. Shoulder-length black hair stuck to the side of her neck. The September air should have been cool. It was not. It lay against her skin like breath held too long, sweet with something that had no business blooming after dark. She knew the standing stones by the way the ground told her she had crossed them. One moment the grass was park grass, flattened by deer and weekend feet. The next it was deeper, springing under her trainers, and the trunks around her had the look of things that had been set down rather than grown. Ancient oak, pale where the torch caught the bark, ringed in a loose circle that did not quite close. Isolde's grove, if the scrap of paper in her pocket was telling the truth. She had not met Isolde. She had only followed the heat. The Heartstone sat against her sternum on its silver chain, no bigger than a thumbnail, and it had been warm since she locked the flat above Silas's bar. Not the faint pulse she had learned to ignore on certain streets near the river. This was steady, a small coal under the cotton of her shirt, and it had tugged her south and west until the park gates and then inward, past the places the maps agreed on. She had come because the warmth had a direction, and because three nights of it waking her had begun to feel like a summons she would rather answer on her own terms. Cool head. Quick thinking. That was the version of herself she trusted. She touched the crescent scar on her left wrist without meaning to, the old childhood mark, and told herself the grove was only a place with a reputation. The wildflowers disagreed. They stood open in the torch beam, white and violet and a red so dark it drank the light, petals beaded as if with dew though the night was dry. Year-round, someone had written on the back of the scrap, in a hand she did not know. She had laughed at that in the kitchen. She was not laughing now. The blooms leaned, not toward the torch, but toward her chest, toward the pendant, with the slow attention of things deciding whether to speak. Aurora stopped at the edge of the clearing and switched the torch off. Darkness came in wrong. It should have been London-dark, orange at the rim from the city beyond the trees. Instead the sky above the grove was a flat, starless black, and the only light was the faint inner glow of the stone at her throat, deep crimson, no brighter than a coal seen through fingers. Her bright blue eyes adjusted poorly. Shapes remained shapes. The standing oaks. The pale drift of flowers. A low mound at the center that might have been earth or might have been the back of something sleeping under grass. She listened. Richmond at night was never this silent. There should have been a road somewhere, a fox, the metal tick of the gate she had climbed. There was only her own breath and, under it, a sound like cloth drawn slowly over stone. She turned her head. The sound did not come from any one direction. It seemed to arrive already inside the circle, as if the grove had been making it before she arrived and had only now allowed her to hear it. "All right," she said, and her voice came out smaller than she liked. "I'm here." No answer. The cloth-sound continued. She took three steps in and the pendant flared, heat jumping from warm to near-painful against her skin. She hissed and lifted the chain so the gem hung in the air between her fingers. The crimson glow strengthened. Not a Hel portal, she told herself, because she had felt that once near the river stairs and the pulse had been a knock, irregular, hungry. This was a held note. Continuous. Wrong in a different key. At the edge of her vision, left side, something shifted among the oaks. She did not whip around. She had learned, delivering bags through alleys, that sudden movement made you the interesting thing. She turned her face a fraction and let her eyes go where the movement had been. Nothing. Bark. Shadow. A flower stem recovering from a bend she had not caused. Her pulse knocked once, hard, in her throat. She counted her breaths the way her father counted points in an argument, one clean number after another, until the knock settled. Then she heard the second set. Not footsteps. Breathing. Matched to hers and half a beat late, as if whoever stood behind the nearest oak had needed a moment to find the rhythm. Aurora held her own breath. The other breathing continued for two cycles, soft, human-sized, and then stopped when she did not resume. The silence after it was worse. It had the quality of attention. "If you're going to follow me," she said, "you can do it where I can see you." The grove gave her the dry tick of a petal falling. She watched it land on her shoe. When she looked up, the mound at the center was closer than it had been. She had not walked. She was certain she had not walked. The oaks behind her had multiplied, or the circle had tightened, the pale trunks standing nearer her shoulders than the width of the clearing allowed. Time, the scrap had said. An hour inside can be minutes or days outside. She had read that as folklore. Standing in it, she understood it as a door left ajar. Her phone was in her back pocket. She drew it without taking her eyes off the mound. The screen lit her fingers and died. No signal. The clock read 00:00, and when she thumbed it the numbers did not change. She put it away. The pendant's glow painted the underside of her chin red. Something moved again, this time on the right, a narrow vertical dark that detached from an oak and became, for the length of a blink, the shape of a person her own height. Straight hair to the shoulder. A tilt of the head she recognized because she had seen it in windows. Then it was bark again, and the recognition sat in her stomach like a swallowed stone. She did not run. Running in a place that rearranged distance seemed like the sort of clever idea that got people lost between one minute and the next day. She walked instead, deliberately, toward the gap she remembered between two stones, counting paces. One. Two. Five. At seven the ground softened and the sweet smell thickened until it coated her tongue. At nine she stopped because the gap was no longer a gap. An oak stood there that had not stood there, its bark split in a long pale seam, and from the seam came the cloth-sound, closer now, intimate as a sleeve brushing a wrist. Aurora set her palm on the trunk. The wood was warm. Under her hand it rose and fell, once, the way a chest does. She pulled her hand back. The crescent scar itched, a thin bright line of sensation, as if the old cut had remembered the moment it was made. She flexed her fingers. They worked. She was still herself. The thought did not comfort her as much as it should have. "I came for an answer," she said to the dark. "Not a game." The breathing started again, not behind her this time but above, in the branches, a soft human inhale that stirred the leaves without wind. A flower near her ankle turned its face up. In the dew on its petal she saw a reflection that was not the sky and not her torchless face: a small red light, pulsing, and around it a darkness with the suggestion of an opening, a mouth in the air that the grove was trying not to be. The Heartstone answered it. Heat climbed the chain into her fingers. She almost dropped the gem. She did not. If she let go of it, she had the sudden, precise conviction that the grove would decide the pendant belonged to the mound, and that she would spend whatever passed for hours here looking for a glint in the grass while something learned the shape of her breathing for good. A voice spoke her name. Not Rory, which was what Eva used, what the kitchen at the Golden Empress used when the orders stacked up. Aurora, full and careful, in the cadence her mother used when she was trying not to sound afraid. It came from the center of the clearing, from the low mound, and it was almost right. The vowel at the end held a fraction too long, as if the mouth making it had practiced on a recording and missed the way Jennifer Carter let the name fall. Aurora did not answer it. She turned, slow, and put the pendant back against her shirt so both hands were free. The glow leaked through the fabric, a coal she could not hide. Around the circle the oaks had drawn in until she could have touched two of them by spreading her arms. Between them the park was gone. No path. No gate. No orange rim of city. Only the black overhead and the flowers, all of them open now, all of them leaned toward her chest, and in the spaces between the trunks the narrow vertical darks that were not quite people and not quite trees, holding still the way deer hold still when they have already seen you. One of them blinked. She saw it at the very edge, a wet glint where no eye should have been, gone when she looked straight on. Her skin went tight along her arms. The cloth-sound resolved, finally, into something she could name: not cloth. Pages. A turning, over and over, somewhere under the mound, as if a book were being read by a hand that did not need light. The voice that was not her mother's tried her name again, softer, and then tried another word, one she had not offered anyone in this park. Laila. The alias sat wrong in the air, a key turned in a lock she had not known was on her. Whoever had given her the pendant had known more than a delivery address. Whoever was under the grass knew the same. The breathing in the branches matched her again, perfectly this time, and a third breath joined it from the left, and a fourth from the seam in the oak, until the grove was full of her own rhythm worn by other lungs. Aurora backed one step. The mound advanced by the same measure, grass shivering as if something beneath it had shrugged closer to the surface. She stopped. It stopped. The pendant burned steady, a warning and a beacon, and she understood with a cold clarity that did not feel like panic that she had not been led here to find a door. She had been led here because something on the other side of the boundary already knew she would come, and the grove, Fae-touched and old and not kind, was holding its breath to see which of them would move first. She kept her eyes on the mound. She did not look at the blinks. She set her feet in the springing grass and made her voice level, the voice she used when a customer raised his, the voice that bought her a second to think. "You don't get my name for free," she said. The pages stopped turning. In the silence that followed, every flower in the circle leaned in at once, and the dark between the oaks took one shared, soundless step toward the light at her throat.
