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 she wouldn't come here after sunset. She'd told herself a lot of things, in the weeks since Eva had first pointed out the oaks between the ferns and called them standing stones. But the pendant had begun its warming just after she'd stepped off the bus at Richmond Gate, and by the time her trainers hit the long grass of the park it was a small red ember against her sternum, as if it had swallowed a lit match and kept it there, glowing through her shirt. She needed to know why. The park at night was not the park by day. The bracken had swallowed the paths, and the sky above the trees had a queer bronze quality where London's light haze met the overhanging oak canopies. Her torch cut a narrow cone through it all, catching moths that were the wrong colour — dust-pale, almost silver — and the occasional startled flash of deer eyes that vanished before her brain could finish registering them. She found the standing stones by accident, the way one always did. One moment she was pushing through nettles, swearing quietly at her ankles; the next, she was between two mossed trunks of oak, and the air changed. It was the smell first. The damp-leaf, dog-walked smell of Richmond Park fell away, replaced by something greener and older, like cut grass in June, like apples turning on a shelf. Then the temperature: ten degrees warmer, maybe more, a honeyed warmth that pressed at her throat. The wildflowers at her feet were open. Foxgloves. Cornflowers. Primroses. Things that had no business blooming in October and certainly no business blooming at night. "Right," Rory said, because saying something aloud felt important, "I'm here." The Grove did not answer. She hadn't expected it to. But the silence that followed her voice was too complete, as though her single syllable had been wrapped in cloth and carried away. She could not hear the distant mutter of the North Circular. She could not hear a plane. She could not hear her own blood. She clicked off her torch. The moon, when she looked up, was in the wrong place — a finger's breadth too far west, and the wrong shade of white. She put her hand on the pendant. It pulsed once against her palm, a slow and almost affectionate warmth, like a cat acknowledging her. "Okay," she whispered. "Okay. Just — look around. Don't touch anything." She walked the clearing's perimeter. Her boots made almost no sound on the moss. When she put a hand to one of the oak stones, the bark was warm under her fingers, warmer than the air, and she felt — or imagined she felt — something on the other side of it shifting its weight. She took her hand back. Halfway around the ring, the Grove began, very politely, to go wrong. It was nothing she could name. The wildflowers she'd already passed were still blooming, yes, but they were facing her now — the heads of the foxgloves had turned, stems leaning minutely on their axis, as if the Grove had been tracking her while her back was turned. A primrose at her ankle trembled without wind. She stopped walking. Behind her, something exhaled. Not a breath. An exhale. Long, patient, far too low for any animal that belonged to this island. She felt the warmth of it on the nape of her neck an instant before she registered the sound. Rory turned. Nothing. The clearing was empty. The moonlight laid itself neatly across the moss and the nodding flowers, and there was nothing there, nothing at all, and still her hindbrain insisted, with the cold clarity of an animal that has lived a long time by believing itself, that she was being watched from very close. She counted her breaths. One. Two. Three. The pendant at her chest was hot now, hot enough that she could feel the outline of it through the fabric, a small crimson heart beating just out of time with her own. Somewhere in the treeline — or what passed for a treeline in a place that had only the illusion of edges — a child laughed. It was a bright, delighted sound, the laugh of a six-year-old being chased by a patient parent, and it cut through the honeyed air of the Grove so wrongly that Rory's stomach turned. There was no child. There couldn't be a child. She was forty minutes' walk from the nearest gate, and it was past ten, and there was no child. The laugh came again, from a different direction. "Stop it," Rory said, quietly, to no one, to whatever was listening. "I'm not here to play." A pause. She felt it consider her. Then, softly, from just behind her left shoulder — so close that her hair should have stirred — a voice said, almost conversationally, her name. Not Rory. Not Aurora. The other one. The one she had not told anyone. The one that did not, as far as she had ever known, belong to her at all. "Malphora." She did not turn. She did not think she could have moved her feet if the whole Grove had caught fire. Her torch was dead in her hand, though she had not switched it off. The pendant was searing now — a point of pain she welcomed, because pain was something she understood, pain was hers. At the edge of her vision, just at the corner, something pale passed between two of the oaks. Tall. Too tall. She did not look at it directly. She had the sudden, unshakeable sense that looking directly at it would be the last discourteous thing she ever did. The child laughed again, delighted, from inside her own skull. Rory took one step backward. Then another. The flowers bowed their heads around her boots — not away from her, but toward her, as if in greeting, as if welcoming someone home. She did not run until she was past the stones. Behind her, the Grove breathed out once more, and let her go, and she understood, with a certainty that would keep her awake for a long time after, that it had let her.
