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.

Rory had told herself it was curiosity. That was the lie that got her off the last District line train at Richmond and through the park gates before they locked. Curiosity was clean. It did not require her to admit that the pendant against her collarbone had been pulsing for three nights running, a faint heat like a second heartbeat, or that she had traced old forum posts and a half-remembered comment from Eva until the words Richmond and standing stones and grove sat in her mind like an address. The park at night was a different country. Streetlight died at the boundary. The paths were pale suggestions under a thin moon, and the trees stood in ranks that seemed to lean inward the farther she walked. Her trainers made almost no sound on the packed earth. She kept her hands in the pockets of her jacket and her eyes moving, the way she did on late deliveries through parts of the city that had never learned to be kind. Cool-headed, people called her. She had always taken it as a compliment. Tonight it felt like a thin coat. She found the stones where the map in her head said they would be, a ring of ancient oaks so old their trunks had the look of petrified muscle. They did not belong to the tidy geometry of Richmond Park. They belonged to something that had been here first. Wildflowers grew between them in a dense, impossible carpet, pale in the moonlight, open as if it were noon in June. Rory stopped at the edge of the ring and felt the air change. It was warmer inside. Sweeter. The city smell of damp tarmac and exhaust fell away as if someone had closed a door. She stepped through. The pendant flared against her skin, a pulse of heat that made her suck in a breath. She hooked a finger under the silver chain and drew the thing out. The crimson stone, no larger than her thumbnail, held a faint inner glow, as if a coal burned at its heart. It had done that before, in the flat above Silas's bar, in the alley behind the Golden Empress, once on the bus when she had been half asleep. Never like this. The warmth was insistent. Near a Hel portal, she thought, and then wondered where the phrase had come from, because she did not remember reading it. An hour inside can be minutes or days outside. She had read that too, in a comment so old the account had been deleted. She checked her phone. No signal. The time read 11:47. She put it away and stood in the center of the clearing and listened. Silence, at first. Then not silence. The flowers made a sound when there was no wind, a dry, papery shift, as if something small were moving among the stems. Rory turned a slow circle. The oak stones watched her with the blank patience of things that had outlasted every witness. Beyond them the park should have been visible, the slope, the distant glow of London. It was not. The dark between the trunks was thicker than it had any right to be, a wall of it, and the longer she looked the less she trusted the idea that the path she had taken still existed on the other side. She was not a woman given to panic. She had left Cardiff with a bag and a bruise and a name she no longer used, and she had built a life out of late shifts and cheap rent and the particular London skill of not looking too closely at what did not concern her. This concerned her. The pendant had been left on her doorstep six weeks ago in a box with no return address and a card that said only her name. Aurora. Not Rory. Not the name on her delivery lanyard. Someone knew the name her mother had given her. A twig snapped to her left. She turned. Nothing. The flowers were still. She waited, counting her own breaths, and heard a second sound from the right, the same dry break of wood, too deliberate to be an animal. Deer did not pace. Foxes did not circle. Rory let her hands hang loose at her sides and kept her feet where they were. Running would mean choosing a gap between the stones, and she was no longer certain the gaps led out. "Hello?" Her voice came out smaller than she liked. It did not echo. It fell into the clearing and died, as if the air had thickness enough to swallow it. She tried again, louder. The same result. The silence that followed was worse, because it felt attentive. Something moved at the edge of her vision, a pale smear between two oaks, there and gone when she snapped her head toward it. She did not call out a third time. She took a step backward and felt the wildflowers crush under her heel with a sound like a sigh. The pendant's heat climbed. It was no longer a pulse. It was a steady burn, just short of pain, and the glow from the stone threw a thin red light across her fingers and the crescent scar on her left wrist. She had gotten that scar at eight, falling off a wall in Cardiff, her father's voice somewhere above her, sharp with fear. She had not thought of it in years. Looking at it now, in that ugly little light, she had the unwelcome sense that the grove knew the story. That the grove had been waiting for the girl who had fallen and the woman who had run. Another sound. Not a twig. Footsteps. Soft, unhurried, matching the pace of a person walking the circumference of the ring. Rory turned with them, or tried to. The sound stayed always just behind her left shoulder, no matter how fast she spun. When she stopped, it stopped. When she held her breath, she heard breathing that was not her own, slow and even, close enough that she should have felt it on her neck. She was not alone. The certainty arrived without drama, a cold fact settling into the space behind her ribs. She had come here for answers and had brought herself like an offering. The flowers, the stones, the stolen time: none of it had been hidden from her. It had been arranged. She thought of Eva's voice on the phone last week, too bright, asking if Rory had been sleeping, if she had noticed anything strange. She thought of the benefactor who had known to leave the Heartstone on a scuffed welcome mat above a bar in a city of eight million people. The footsteps resumed. Closer. Rory did not run. She turned to face the direction the sound seemed to occupy and found only the same dark between the oaks, the same pale flowers, the same red glow painting her hands. Her mind, which had always been her best tool, began to offer explanations in a tidy queue. Wind. An animal. A trick of acoustics in a bowl of old trees. Exhaustion. The pendant's heat confusing her senses. Each explanation arrived and failed in the same instant, because the breathing continued, and because something at the very limit of the light took a step that made the flowers bow. She saw it only in pieces. The suggestion of a height. The wrong angle of a limb. A face that was almost a face, the way a reflection in black water is almost a face. It did not come into the clearing. It waited at the boundary, as if the standing stones were a courtesy it had decided, for the moment, to observe. Rory's mouth had gone dry. She could hear her own pulse in her ears, faster than the pendant's rhythm, and she understood with a clarity that felt like a gift and a curse that the thing had been here before she arrived. That it had watched her cross the park. That the pulsing of the stone had not been a guide so much as a summons, and she had answered it. "I don't want this," she said, and hated the shake in it. The breathing changed. It might have been a laugh. It might have been the flowers again. The figure did not advance and did not retreat. Time, which the grove was said to treat as a suggestion, stretched until Rory could not have said whether a minute had passed or an hour. Her phone was a dead weight in her pocket. The moon above the clearing had not moved. She thought of her flat, of the smell of frying oil that clung to her jackets, of Silas locking up downstairs, of the ordinary London night continuing without her, and the thought was so sharp it might have been grief. She took a step toward the nearest gap in the stones. The footsteps behind her matched it. She took another. So did they. The presence at the boundary did not need to enter. It had already arranged the terms. Rory stopped again, and the silence rushed back in, thick and sweet and listening. The pendant's glow brightened until the crimson light reached the first of the oak trunks and showed her, for half a second, a second set of footprints in the crushed flowers. They were not hers. They were not quite the shape of any shoe she knew. They pointed inward, toward the place where she stood. She closed her hand around the Heartstone until the silver chain bit her palm. The heat was almost unbearable now, a live coal she refused to drop. Cool-headed. Out-of-the-box. She had not come this far, through an abusive house and a city that ate the unlucky, to freeze in a ring of trees. She turned her back on the footprints and walked, not toward the gap she had entered by, which she no longer trusted, but toward the far side of the ring, where the dark between the oaks looked fractionally thinner, as if a path might still remember how to be a path. The breathing followed. The pale smear at the edge of her vision kept pace. The flowers sighed underfoot. Rory did not look back. Looking back would make it real in a way she was not prepared to survive. She kept her eyes on the stones and counted her steps and told herself that the park was still there, that Richmond was still there, that the last train had not yet become a story she would never get to tell. When she reached the boundary, the air cooled by a single degree. The city's distant murmur, or the memory of it, brushed her hearing like a radio finding a station. The pendant's burn eased, just enough to let her unclench her jaw. She did not celebrate. She stepped through the oaks with the same care she had used to step in, and the grove let her go the way a hand opens when it has already taken what it wanted. Behind her, in the clearing she would not turn to see, something stood in the crushed flowers and watched the gap close. The moon, which had not moved, began at last to slide. Rory walked the dark path with her shoulders tight and her scar itching and the Heartstone cooling against her skin, and she did not let herself wonder how much time the grove had kept. She only walked, and the park slowly became a park again, and the wrongness receded in layers, like a tide that had decided, for tonight, that the shore was enough.
