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 first thing Rory noticed was the silence between her footsteps. Richmond Park had been noisy on the way in. Wind had worried the bare branches, and somewhere beyond the path a fox had given one of its ugly, human cries. But as she passed between the two ancient oaks that marked the grove’s edge, each step seemed to land in its own pocket of quiet. Her boots pressed into damp grass. She heard the soft crush of it, and then nothing, until she lifted her foot and put it down again. She stopped. Behind her, the park waited in darkness. Ahead, wildflowers nodded in the clearing as if a mild breeze crossed them, though the air against her face was still. Rory looked at her phone. 11:47. One bar of signal, then none. She slipped it back into her coat pocket and touched the pendant beneath her scarf. The stone was cool. That, at least, was what she had come to check. Three nights ago, the thumbnail-sized gem had warmed against her chest while she stood in the queue at a cash machine. She had mistaken it for her own pulse until it grew hot enough to make her pull the silver chain away from her skin. Across the street, between a closed chemist and a wall plastered with theatre posters, a darkness had opened where there ought to have been brick. It had lasted the time it took a bus to pass. When the bus was gone, the wall was whole. She had waited until a night off work to return to the grove. If the Heartstone could warn her near that kind of opening, she wanted to know whether it would do so here, at a place already half outside the world. She wanted to find out in daylight. By the time she reached Richmond, the afternoon had been swallowed by a train delay and a long, cold walk, and she had kept going rather than turn back with nothing learned. She took another step into the clearing. A bird sang. It was a bright, complicated little burst of sound, the sort that belonged to a May morning. Rory looked up into the dark canopy. The song stopped midway through a phrase. “Right,” she said quietly. “Lovely.” She had meant to walk a circuit of the grove, note whether the stone changed, and leave. Fifteen minutes, by her phone. No lingering. Time here could make a liar of clocks. She started along the edge, keeping the oak markers in sight behind her. The flowers brushed her shins: white stars, yellow cups, a scatter of purple blooms she couldn’t name. They were fresh and open under a sky that held no moon. Farther in, the grass gave way to a patch of black earth beneath an old tree. From that direction came the faint scrape of something being dragged. Rory stood still. The sound came again, a slow pull over dirt, then a little bump. A branch, perhaps. An animal nosing through fallen wood. She took her torch from her pocket and clicked it on. The beam caught pale trunks and flowers shining wetly. Nothing moved beneath the tree. The earth there was smooth except for a shallow line that ran from the roots toward the centre of the clearing. She kept the light on it. The line ended at a stone half buried in the grass. A soft footfall sounded behind her. Rory turned at once. Her torch swung over the flowers, the gap between the oaks, the path beyond. Empty. She waited long enough for the ache in her hand to tell her how tightly she was gripping the torch. Then she lowered it and put two fingers against the Heartstone. Still cool. A rabbit, she thought. The fox, even. Something she had startled into hiding. The next footfall came when she moved. She stopped; it stopped. She walked three paces, slowly. On her third step, the sound followed from behind her, not quite in rhythm. Rory turned again, faster. In the narrow swing of light she caught the impression of a dark shape beside the nearest trunk. She held the beam there. Rough bark. A split where a branch had been torn away years ago. No shape. She backed toward the oaks. The bird began its song again. Same notes, same clipped ending. Her phone showed 11:47. She stared at it. The screen was bright and ordinary in her hand. She had walked a fair way around the clearing. Even allowing for her nerves, a minute should have passed. She switched the display off, counted slowly to sixty, and checked again. 11:47. The battery had dropped from sixty-two per cent to fifty-eight. “Fine,” she said. Her voice sounded close to her mouth and nowhere else. The grove had never felt large before. Now the pair of marker oaks seemed farther away than when she had entered. She could see the darker seam of the path between them, but walking towards it felt oddly like looking down a corridor in a dream: it remained at the same distance while the details around her slipped by. She fixed her eyes on a white flower beside the path. One step, then another. The flower passed her boot. She picked another, and another. That helped. At least the ground was moving. The dragging sound resumed behind her. She refused to look until she reached the boundary. She knew how a frightened mind worked. Give it a dark shape and a noise, and it would invent the rest. Then a voice behind her said, “Wait.” It was a woman’s voice, low and breathless. Rory stopped before she could help it. The word had come from close by. Not from the tree, where the scrape had started. From just behind her shoulder. She looked down at the grass. A narrow strip of flowers lay flattened along the route she had taken. She had not gone that way. Her tracks were to the left, clear in the dew. “Who’s there?” The question went out into the clearing and seemed to stay there. No answer came. The bird did not sing. Rory’s left wrist prickled beneath her sleeve, right where the old crescent scar lay. She caught herself rubbing it and dropped her hand. She moved again, keeping her torch aimed at the gap between the oaks. The light reached the path and stopped. Beyond it, Richmond Park should have offered something: a branch stirring, a slope of grass, a distant wash of traffic. There was only darkness, level and blank. Behind her, a boot pressed into wet ground. It made exactly the sound hers had made a moment earlier. Rory took a short step. The other step answered. She took two quick ones. Two followed, each a fraction late. She spun and shone the torch across the clearing. Nothing stood among the flowers. In the beam’s edge, one cluster of purple blossoms bent down, then eased upright. The Heartstone warmed. For a moment she held it through her scarf, hoping she had imagined the change. Warmth spread across her fingertips, steady and unmistakable. Somewhere near her, a portal to Hel was opening—or had already opened. She swept the torch over the clearing again. She knew what she was looking for now, and that made the empty spaces worse. A gap between trunks. A shadow without a tree to cast it. The shallow line in the earth. It had grown longer. It ran nearly to her feet. Rory stepped across it. The warmth in the pendant sharpened until she pulled it free of her scarf. Deep crimson glowed faintly within the stone. As she held it away from her body, the heat eased. She moved it towards the line; the gem heated again. The line did not mark something dragged across the soil. It marked where the soil had parted. As she watched, a grain of earth tipped into it and vanished. She turned for the marker oaks and walked quickly. The other footsteps followed. She did not run. Running would mean listening to them run too. At the trees she found that the gap between them was not where she had thought. One trunk stood several feet to the right, close enough that she could see a pale slash on its bark. The other stood beyond a thick bank of flowers. They looked like the same two oaks that had let her in, but the path between them curved away from the park and back into the clearing. She stopped at the first tree and put her palm against it. Solid bark. Cold, rough, damp. The footstep behind her stopped. In the stillness that followed, someone drew breath. Rory kept her hand on the oak. She could feel its ridges pressing into her skin. The breath came again, close to the back of her neck. It caught slightly on the inhale, the way hers did when she tried not to cry. She held her own breath. So did it. A hard little laugh almost escaped her. She swallowed it. If the grove was folding the path, she could not trust what she saw. The pendant had reacted to the line in the earth. It might tell her where the opening was, and where it wasn’t. She raised the chain. The Heartstone burned when she pointed it towards the centre of the clearing. It cooled when she turned it towards the oak beneath her hand. Then, as she moved it slowly past the trunk, it cooled further. Rory edged around the tree. The flower bank shifted in the corner of her eye. She looked straight at it. Nothing. Her torch caught a narrow space between the blossoms and the second oak, no wider than her shoulders. Beyond it stood a pale tangle of dead bracken. It might have been the park. She could not be sure. The voice behind her spoke again. “Rory.” It used Eva’s voice this time. Rory felt the pull of it before she had a thought to put against it. Eva had said her name a thousand ways since they were children; this was one of them, gentle and impatient, asking her to turn round and listen. Eva was not in Richmond Park. Rory had not told her she was coming. She kept moving around the trunk. The pendant lay cool in her hand, though its glow lingered. One foot slid into the narrow space. Branches snagged her coat. Her next step brought her shoulder against the second oak. “Rory,” Eva called, and beneath her voice came another sound: Rory’s own boots crossing the clearing towards her. She pushed through the bracken. Dead stems snapped against her face. For one blind second her torch lit nothing but pale twigs. Then the ground sloped beneath her, and wind struck her cheeks. Richmond Park opened ahead: grass silvered with frost, a dark line of trees, the distant amber lights of the road. Rory went another twenty paces before she stopped. The air smelled of wet leaves and exhaust. Somewhere far off, a fox screamed. Her phone read 2:16. She turned back. The oaks stood among the other trees, close together now. Between them she could see only bracken. No flowers. No clearing. The pendant had gone cold. She tucked it beneath her scarf with stiff fingers and started towards the road. After a few steps, she heard a footfall behind her. Rory stopped. The sound did not repeat. She waited, facing the open park, until the wind moved through the grass. Then, very carefully, she took another step.
