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 had been warm against her sternum for three days, and Rory had finally stopped pretending otherwise. It started as a low hum, the kind of heat you get from a phone that's been in your pocket too long. Then it settled in, steady, patient, and she'd find herself at odd moments pressing her palm flat over her shirt to feel it, standing in the middle of the Golden Empress with a bag of cold noodles in her other hand, trying to remember what she'd walked into the kitchen for. By the third night she'd stopped trying to explain it and started following it instead. Richmond Park at half past eleven was a different country. The gates were closed. She'd come over the fence at the Roehampton gate with her jacket snagged twice and a scraped knuckle she kept meaning to deal with, and now she was walking north by the light of her phone and the thin advantage of a half moon, and the city had gone somewhere behind her, forgotten like an umbrella. She'd been here before. Once. In summer, with Eva, and the grass had been full of families and the ice cream van had been playing something tinny and wrong-keyed, and they'd thrown a tennis ball for a spaniel that wasn't theirs. It was not summer now. That was the first thing. The second thing was the quiet. Not silence — Richmond Park never gave you silence, there were always cars on the A3 bleeding through the trees, planes stacked low over Heathrow, the whole grey hum of London sitting on the horizon like a lid. That hum was still there. She could hear it if she concentrated, cupped a hand behind her ear like an idiot and listened. But it was underneath something else now. A heaviness in the air that made her own footsteps sound muffled, as if she were walking through a room hung with heavy curtains. As if the sound had to push its way out of her. She checked the map on her phone. The blue dot hovered, wobbled, and then jumped three inches west, into a thicket of green with no path through it. She stopped walking. "Right," she said aloud, because silence was worse. Her voice came out small and flat, swallowed whole. She put the phone away. The pendant pulsed. Not warm now — hot, a small fierce heartbeat against her chest, and she gasped and pulled the collar of her shirt away from her skin, because for a second it had felt like it might actually burn. She fumbled at the clasp, got the chain over her head, and held the thing in her palm. The stone glowed. Not brightly; just enough that she could see the deep red of it lit from somewhere inside, the light pooling in the creases of her hand like blood welling up through a cut. It hadn't done that before. It had only ever been warm. Somewhere ahead of her, in among the trees, something made a sound. Rory's hand closed around the pendant. She didn't move. It wasn't an owl. Owls sound like owls; she'd grown up with tawny owls behind the house in Cardiff, that flat ghostly whooo that had scared her at seven and bored her at fourteen. This was lower. It was almost like a deer, the bark of a deer, but there was a shape inside the sound that a deer couldn't make. It had a vowel in it. It had an edge on the end, like the last of a word bitten off. She waited for it to happen again. The trees didn't move. That was the thing she noticed while she waited — not the sound, the not-sound. There was a wind somewhere, she could feel it on her face, cool and moving, but the canopy above her held absolutely still. Every leaf. As if the trees were indoors. As if they were painted. Rory had spent twenty-five years being a person who thought her way out of things. It was what she was for. It was what she'd done with Evan, two years of quiet accounting, saving, planning, the bus ticket bought a week in advance and hidden inside a book. She had never once in her life made a decision out of fear. She was afraid now. She was also, standing in that unlit corridor of trees with a glowing stone in her hand, aware that she had walked here on purpose. The stone had brought her. And something was here to meet it. She thought, very clearly: *don't be stupid.* Then she began to walk again, north, past the treeline and out onto the open grass, and the grass was full of flowers. They were blue. They were blue and yellow, cornflowers and something else, and they were blooming in November in their thousands, standing up out of the cropped grass in a field in Richmond Park at midnight as though somebody had gone over the whole thing with a paintbrush. She stopped at the edge of them and looked at the nearest one. It was real. It had petals. It had frost on it, tiny crystals catching the moonlight along the edge of the petal, and underneath the frost it was alive, and it was opening. She heard her own breathing get loud. The ground under her feet was wrong. Not the flowers. The ground. She looked down and saw that the turf had changed, the close-cropped park grass giving way to something older, softer, a mat of dark moss and little white wood anemones that should have been closed for the night, and they were open too, every one of them, open toward the sky like upturned faces. They were open toward her. The pendant turned cold. So fast it hurt, like holding a coin against your tongue. The shock of it made her drop it, and the chain whipped across her wrist and the stone swung and struck her leg, and she crouched to catch it before it hit the moss, and when she looked up again, the standing stones were there. She had not walked to them. She was certain of that. There had been open grass in front of her a moment ago and now there were eight trees, eight enormous oaks, dead and bare and grey, arranged in a ring around a circle of moss she could have crossed in fifteen strides. The blue flowers stopped at the line of them. Nothing grew between. Rory stood very slowly. Her knee clicked. She was, she noticed, gripping her own wrist where the scar was, the small crescent from the bicycle when she was nine, pressing on it with her thumb like it was a button that might do something. In the middle of the ring, the moss was flattened. It was a person-shaped flattening. An impression, a bruise in the green, roughly the size of a grown adult lying flat on their back with their arms at their sides. The moss had not sprung back. It sat there, in the middle of the ring of oaks, holding its shape the way a mattress holds a shape, and Rory looked at the way the arms lay, and looked at the way the head tilted to one side, and then she looked at the edge of the ring, where the moss was scuffed and torn in a long line that ran away from the impression and out between two of the oaks toward the dark. Something had been lying there. Something had been lying there a long time, and then it had dragged itself out. Very quietly, from somewhere beyond the treeline in the direction the drag-marks went, something answered the sound she had heard earlier. The same vowel, the same bitten end, but closer. Closer, and this time it was a question. Rory turned and ran. She ran the way you run in dreams, knees high, the ground refusing to help her, the blue flowers closing behind her as she went, she felt them go, felt the petals brush her ankles, and she did not look down and she did not look back, and the whole field seemed to be folding up behind her like a page being turned. The fence at Roehampton gate was where she'd left it. She went over it blind, tore her palm open on the wire, landed badly and got up anyway, and only when she was on the road with the streetlights rank and orange overhead and a night bus sighing past her did she stop and bend double and try to breathe. Her phone said 23:41. She had come over the fence at 23:28. Thirteen minutes. The pendant was cold against her chest, and when she finally dared to take it out and look, the glow was gone, and the stone was only a stone, deep red and dull, no more alive than a pebble she might have picked out of the gutter. She held it in her torn hand and watched her own blood get into the setting, and the road hummed under her, and London stood around her on all sides, bright and ordinary and full of people who had no idea what a field could do when nobody was watching it. She walked home. She did not sleep. And at four in the morning, half-dreaming on the floor of her flat with every light in the place on, she felt it pulse once, soft and warm, against her palm.
