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 grass inside the ring of stones was dry. Rory noticed because her boots had been sinking into mud all the way across Richmond Park. The soles had picked up enough of it to make each step heavy, but here, among the wildflowers, they came away clean. She stopped with one foot still between the two nearest stones. Behind her, the path ran back through the trees, pale where the moon reached it. Ahead lay the clearing she had come to find. The pendant warmed against her chest. “Right,” she said. Her voice fell flat. She had expected an echo, perhaps, or the small rustle of something fleeing through the grass. Nothing answered. Even the traffic she’d heard beyond the park gates had gone quiet. An hour earlier, the Heartstone had begun to pulse while she was carrying a delivery from the Golden Empress. It had never done that in the restaurant, or in her flat above Silas’s bar. By the time she handed over the food, the little crimson stone was warm enough to feel through her shirt. The pulse had eased whenever she walked away from the park and quickened when she turned back. She had followed it on foot, intending to learn where the warmth stopped. At the boundary of the grove, it had sharpened to a steady beat. Now she could tell anyone she needed to tell exactly where it had led her. She ought to leave. Rory turned to look at the path again. Between the trees, she could see the last stretch she had walked. She could even see a patch of churned mud where she had nearly slipped. She took out her phone and photographed the stones. On the screen, the picture showed wildflowers and black trees. The stones were absent. Rory lowered the phone. Two stood on either side of her, close enough to touch. Farther round the clearing, more rose among the grass, old and broad and darkly ridged. She lifted the phone again and watched them disappear into the image. “Brilliant.” She took one step backward. Somewhere ahead of her, a boot came down on wet ground. Rory held still. After a moment, she looked toward the sound. The clearing remained empty. White flowers nodded at the edge of the moonlight, though she felt no wind. A second step followed. Closer. She backed out between the stones and onto the path. The mud took her heel with a soft pull. At once the ordinary sounds of the park returned: a car passing far off, leaves rubbing together overhead. Relief made her briefly light-headed. Then the pendant pulsed. Hard. She looked down. Its faint red glow showed through her shirt. She drew it out by the silver chain. The stone, no bigger than her thumbnail, had left a warm patch against her skin. As she turned toward the path home, the warmth subsided. Toward the grove, it rose again. That was enough. She had found the place. Rory started back through the trees. After twenty paces, the traffic disappeared. She stopped and looked behind her. The standing stones were still visible, but farther away than they should have been. She could no longer make out the flowers between them. She checked her phone. No signal. The time read 11:48. At the park gate it had been 11:42. She had walked at least half an hour since then. A bird called above her, three short notes. She waited, listening. It called again, exactly the same three notes, with the same small crack in the last one. From somewhere farther along the path came the sound of shoes crossing gravel. Rory slipped the pendant under her shirt and walked faster. The gravel sound kept a little ahead of her. When her boots met a patch of gravel, it stopped. When she reached dirt, it began again. She stopped beside a low oak branch. So did the other walker. She could have turned on her phone torch. The moon gave her enough light to see the path, but not far into the trees. Showing whoever was out there where she stood seemed unwise. “Hello?” she called. There was a pause, long enough for her to regret it. “Hello?” came back from ahead. The voice was hers. It carried the rough edge she heard in the mornings before her first cup of tea. Rory gripped the phone. Whoever was out there had heard her speak in the clearing. That would explain it, if they were good at imitating people. She almost preferred not knowing why they would bother. “Who’s there?” She waited. The trees held still. Then, from behind her, in her own voice: “Who’s there?” Rory ran. Branches scraped her coat. She kept to the path as best she could, though it bent sharply in places she didn’t remember. Twice her foot slid in mud. She caught herself on a trunk and pushed on, breathing through her mouth. The path opened. She stumbled into the clearing and stopped short. Dry grass brushed her boots. Wildflowers bloomed at her feet, bright as scraps of paper in the moonlight. The stones made their patient ring around her. She turned. The path she had just taken lay between two oaks. She could see her footprints leading out of it, dark mud pressed into the dry grass. A second set lay beside them. They were the same size as hers. One heel had dragged, leaving a narrow groove. She looked back at the path. She hadn’t dragged her heel coming in. The prints continued past her and ended at the nearest standing stone. Rory took three careful breaths. She had come back to the grove somehow. She could find the entrance again and try another direction, or she could stay where she was until morning. Neither choice appealed to her. From the trees behind her came a small crack, like a twig underfoot. She crossed to the stone where the tracks ended. Up close, its surface bore deep furrows that looked like oak bark. She put her fingers against it. It was colder than the night air. The pendant burned against her chest. She pulled it free. In the stone’s faint red light, she saw that the grooves ran down into the earth. Between them lay a narrow patch of darkness. Rory had taken it for a crack. Now she could see straight into it. There was a stairwell on the other side. Painted walls. A strip of worn carpet. The door to her flat above Silas’s bar, with the scratch beside the lock where she always missed with her key. The smell reached her next: old varnish, laundry detergent, the oil that clung to her clothes after a shift at the Golden Empress. She stepped back. The stairwell remained where it was, set inside a gap no wider than her hand. Light showed beneath her flat door. Someone moved on the landing. Rory saw a shadow cross the strip of light, then heard a key scrape at the lock. Her key. She knew the sound of that stubborn lock. The door opened inward. She could see only the edge of it and a slim wedge of her dark hallway. A hand appeared on the frame, fingers braced against the paint. On the left wrist was a small crescent-shaped scar. Rory shut her eyes. The stone pressed cold against the fingers of her other hand. For a moment she heard her own breathing and, quieter, breathing from inside the crack. When she opened her eyes, the hand was gone. The stairwell was dark. Her flat door stood open. She let go of the stone. The view vanished. Bark-dark grooves filled the space beneath her fingers again, with no opening between them. The smell of the stairwell lingered. Rory looked at the pendant. Its crimson heart gave a slow, hot pulse. Whatever it had led her to was here, inside the stone or behind it. She had no reason to go closer. She backed away until flowers brushed her calves. At the far side of the clearing, someone knocked three times. It was the brisk knock she used on deliveries. Three taps, a pause, then the shuffle of feet while she waited for a customer to answer. Rory kept her eyes on the gap between the trees. No one stood there. The knock came again, this time from the stone behind her. She clenched the pendant in her fist. The edges of the gem pressed into her palm. On the path, it had cooled as she walked away from the grove. She could use it to tell whether she was truly getting farther from the stone, even if the path brought her round again. She chose a gap between two standing stones that was nowhere near the path. Beyond it, the ground rose through bracken. She walked toward it, watching the glow between her fingers. The pendant cooled a little. Her pulse raced; she forced herself to keep a steady pace. At the gap, a voice spoke from the grove behind her. “Rory, wait.” She knew what it would sound like before it finished. Her own voice again, now breathless from running. She stepped between the stones. The pendant cooled further. “Rory.” The voice had moved closer. She reached the bracken and pushed through it. Fronds caught at her coat. Beneath them, the earth was wet enough to soak her knees when she slipped. “Please,” the voice said. She got up. Ahead, the trunks stood close together, but she could hear traffic beyond them. She went toward the sound. The pendant was only faintly warm now. Behind her came a hurried tread through the bracken. A branch snapped. Rory broke into a run. She ducked under a bough, found a strip of open ground, and followed it until the trees thinned. A car swept past on the road beyond the park, headlights briefly silvering the gate. She reached it with both hands out. The metal was cold and solid. Through the bars she saw pavement, parked cars, an illuminated bus stop. She climbed the low section of fence beside the gate and dropped onto the pavement. For a while she stayed there, hands on her knees. A bus went by. Its windows showed three passengers, none looking out. Ordinary London night carried on around her. Her phone buzzed. The screen lit with missed calls and messages. Eva had called first. Then again. Silas had sent a message asking if she was all right. Above them all, the date read Thursday. Rory stared at it. She had gone into the park on Monday night. Another message arrived from Eva while she watched: Please just tell me where you are. Rory typed, I’m out. I’m safe. She hesitated over the second sentence, then sent it before she could change her mind. From inside the park came a knock. Three quick taps against the gate. Rory looked up. No one stood behind the bars. The road lights reached the first few yards of path, then gave way to trees. Her phone buzzed again. Eva was calling. Rory answered and held it close to her ear. “Eva?” For a second there was only a rush of breath on the line. Then Eva said her name, angry and frightened, and Rory turned her back on the gate to listen. Three taps sounded behind her once more, softer now. She walked toward the bus stop without looking round, holding the cooling pendant tight in her free hand.
