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 pendant warmed against Rory’s sternum before she saw the stones. She stopped on the path and closed her fist around it. The little crimson gem rested in her palm, no bigger than her thumbnail, its silver chain drawn taut beneath her collar. A faint glow seeped through her fingers. Richmond Park stretched black around her. Somewhere behind her, beyond the trees, London carried on without her: traffic hissing over wet roads, late trains grinding through stations, people turning keys in locks. Here, the darkness had weight. It pressed close between the trunks and filled the hollows beneath the bracken. Rory checked her phone. No signal. The time read 12:17. She had come because the pendant had begun to pulse in her flat above Silas’s bar, warming against her skin with a steady insistence that had left her unable to sit still. It had led her through the park like a compass with no needle. She’d expected some obvious source at the end of it. A light. A gap in the trees. Something she could point to and explain. Instead, there were the standing stones. They rose from the earth in an uneven arc, ancient oaks grown so thick around them that their trunks seemed part of the boundary. She couldn’t tell where the trees ended and the stones began. The shadows there were darker than the rest of the wood, not empty so much as occupied. The pendant gave a small, warm throb. Rory let it fall back beneath her shirt. “Fine,” she murmured. “I’m here.” The words sounded too loud. They seemed to travel into the trees, then stop all at once. She waited for an answer. Nothing came. The grove lay beyond the stones. She could just make out the clearing between the trunks: a low, pale shimmer of flowers, bright against the dark. Wildflowers, blooming in the middle of the night. Their white faces turned toward her. Rory glanced back the way she had come. The path was still there, a narrow strip of grey between the trees. She could see the faint glimmer of her own shoeprints in the damp earth. The sight steadied her. A way back. A simple fact. She stepped through the stones. The air changed. Not colder. Not warmer. Just different—thick, as if she had walked beneath water without getting wet. The smell of leaf mould vanished. In its place came the sweet, green scent of flowers and something underneath it, like a cupboard shut for a long time. Rory stopped and looked behind her. The path remained visible between the trees, though it seemed farther away than it should. The stones framed it in a neat, dark oval. She pulled out her phone. Still no signal. The time read 12:17. A minute, then. Or none. She pocketed it and moved into the clearing. The flowers crowded the ground, white and yellow and a few deep, bruised purples. They grew in unruly patches, untouched by frost or season. Rory crouched near one and ran a finger over a petal. It felt dry, almost papery. The bloom tilted toward her hand. She drew back. A sound came from the trees. Three soft knocks. Rory stood. “Hello?” The sound came again, farther off. Three knocks, patient as someone at a door. She turned slowly, trying to place it. Wood against wood, perhaps. A branch shifting in the wind. Except there was no wind. The leaves above her hung still. Rory took out her phone again. The flashlight cut a pale cone between the trunks. It showed branches, bark, the silver underside of a fern. Nothing else. She aimed the light at the standing stones. The old oaks made a wall around the clearing, though there had been gaps wide enough to walk through. She picked out the opening she’d used. Beyond it, she saw the path. Then something moved at the edge of the beam. Rory swung the light back. Only a tree. Its trunk leaned at an angle, the bark ridged and dark. She stared until her eyes began to water, searching the shadows around it. No movement. No shape. The pendant warmed against her chest. She backed toward the stones. The light wavered once as her hand tightened around the phone. “I’m leaving.” The flowers whispered. It was a small sound, a soft rustle at her feet. She looked down. The nearest blooms nodded, their heads bending away from her. Every flower in the clearing leaned in the same direction, toward the far side of the grove. Rory followed the tilt of their stems. A figure stood between two trees. She couldn’t make out a face. The body was narrow, the head slightly bowed, the arms hanging at its sides. It seemed to wear a dark coat. The phone’s beam reached it and stopped—not literally, but the light dulled before it touched the figure, swallowed in a patch of shadow that clung to its outline. “Can I help you?” Rory called. The figure did not move. She considered the ground between them. Maybe twenty yards. Maybe twice that. The trees could distort distance in the dark. She could return to the stones, get back to the path, and keep walking until the park lights appeared. She had no reason to approach. A soft scrape sounded behind her. Rory spun. The stones were empty. Something brushed the back of her coat. She jerked away, heart beating hard enough to make the pendant jump against her skin. The phone beam swept over flowers, earth, the dark mouths beneath the trees. Nothing there. She listened, breathing through her nose, forcing her pulse to slow. The scrape came again from behind the standing stones. Not a branch. Not quite. It had the rhythm of a shoe dragged over dirt. One step. Then another. Rory moved toward the opening. She kept the phone trained on the gap. “Who’s there?” The figure between the trees had vanished. Her stomach clenched. She looked back over her shoulder and saw only the empty grove, pale with flowers. The way she had come lay ahead. It would be ridiculous to stay and wait for whatever had made the sound. Her fear sharpened into anger at herself, at the pendant, at the whole absurd night. She pushed through the opening between the stones. The path should have been on the other side. Instead, the grove waited. Rory stumbled to a halt. The clearing had changed in no visible way: same flowers, same dark trees, same low silver light. But the stones stood behind her now, a rough arc against the far side of the clearing. She turned in place. Every direction offered trees. “No.” Her voice came out small. She gripped the pendant through her shirt. It was warm, but not pulsing. For an instant she felt a flare of relief. Then a knock sounded beneath her feet. Once. The earth gave a faint, hollow shiver. Rory stepped away from the spot. The ground looked undisturbed, damp soil threaded with fine roots. The flowers trembled around her shoes. A second knock came from somewhere underground. She backed toward the nearest tree, phone light cutting across the clearing. The screen still showed 12:17. Its battery had dropped from sixty-three percent to nine. The three knocks sounded again. This time they came from behind the figure. Rory swung the phone toward the far trees. The figure stood where it had been before, motionless and bowed. The darkness around it seemed thicker now. She couldn’t see its hands. She couldn’t see its face. “Stay there,” she said. The figure lifted its head. A sound escaped Rory’s throat before she could stop it. The face remained hidden, but she had the sudden certainty that it was looking straight at her. The pendant gave a hard pulse. Heat spread beneath her collarbone. She pulled it free, the chain catching briefly on the neckline of her shirt. The crimson stone glowed from within. The figure took one step toward her. Rory moved sideways, keeping the trees between them. Her mind worked despite the fear. The stones marked a boundary. She had crossed through them once; she could find the opening and cross again. If the grove was folding distance, then a straight line would be useless. She needed a landmark. The flowers, maybe. The stones. Something that would remain fixed. She stared at the tallest oak, a split trunk on the left side of the clearing, and chose it as her anchor. Then she started walking toward it, counting her steps. At eleven, a voice behind her said, “Rory.” She stopped. It was her own voice. Not an imitation from a distance, not a sound that merely resembled it. The same low note at the end of her name. The same small roughness in her throat. She didn’t turn around. “Rory,” the voice said again, closer. “Wait.” Her hand closed around the pendant until the chain bit into her palm. She took another step. “Come back.” The voice had changed. It sounded tired now. Frightened. She knew what it wanted her to hear. She knew, too, that the figure had not moved from the trees. Rory kept walking. The split oak was not getting closer. She could see the pale seam in its trunk clearly, but it stayed at the same distance no matter how many steps she took. When she looked down, her shoes were pressing through a drift of flowers. The petals sprang back upright behind her. Something followed at her left. Not footsteps. A quiet breathing, just beyond the reach of the phone light. She swung the beam across the ground. Nothing. Only flowers, all turned toward the place where the figure stood. Then the pendant pulsed again. The light inside the stone flickered, and every flower in the grove bowed toward her. Rory stopped counting. Her mouth had gone dry. She held the glowing pendant out in front of her, its heat seeping into her fingers, and watched the shadows along the trees. One of them detached itself from the trunk. The figure had moved. It stood closer now, though she had never seen it cross the space between them. The phone light still wouldn’t reach its face. Rory turned and ran. She went where the ground sloped, or where she thought it did. Branches caught at her hair and sleeves. Flowers slapped her ankles. Behind her, the voice called her name in the exact cadence of her own breath. She didn’t answer. She didn’t look back. The stones appeared suddenly before her. She hit the ground on one knee, pain bright and clean, then scrambled upright and shoved herself between two of them. The night beyond was silent. Rory stood on the path, chest heaving. The clearing lay behind her, small and pale between the trunks. The standing stones were where they belonged, their dark shapes fixed against the oaks. She looked at her phone. The screen was black. Somewhere inside the grove, three knocks sounded. Rory backed away from the stones. The pendant cooled against her palm. She kept moving until the trees thinned and the park opened around her. Only when she saw the distant, ordinary glow of a road did she let herself breathe. Behind her, from deep in the dark, came a phone ringing. Rory froze. The sound was faint but unmistakable: her own ringtone, the one she had set because she liked its bright, familiar notes. It rang once. Then again. Her dead phone began to ring in her pocket.
