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 oak stones leaned toward her like old men eavesdropping, and Rory paused between them with her breath held, because that was the first thing that felt wrong. The wind had stopped. Not faded, not softened — stopped, the way a radio stops when someone pulls the plug. One moment the Richmond air had been carrying the ordinary hush of late traffic from the Roehampton Gate, the shiver of leaves, a dog barking somewhere behind a fence. The next, silence. A clean, surgical silence, as if the world outside the standing stones had agreed, very politely, to step away. She told herself that was the point. That was why people like Eva spoke about this place in the same hushed voices reserved for funerals and miracles. Time bent here. Sound bent here. Rory had come because the pendant at her throat had been warming for three nights running, tiny crimson pulses against her collarbone like a second, smaller heart, and Eva had said if anything was pulling at it, it would be strongest in the grove. So. The grove. Moonlight pooled in the clearing as though the bowl of it had been poured and left to settle. Wildflowers — foxglove, meadowsweet, a spray of something pale she didn't recognize — shouldn't have been blooming at all in November, and yet there they were, heavy-headed and bright, casting small precise shadows. Too precise. She watched one shadow and waited for the flower to move with the wind that wasn't there. It didn't move. But the shadow did. Just a flicker, the smallest tilt, as if it were cast by a different flower in a different breeze. "Okay," she said, because speaking aloud was something to do with the muscles of her throat. "Okay, Rory." Her voice came out flat and close, like a voice in a carpeted room. She took another step forward and the grass folded under her boots without sound. The pendant pulsed. Warmer now. A slow steady throb, the way a hand presses a bruise to see if it still hurts. She crossed toward the center of the clearing, counting her breaths. Her father had taught her to count when she was small and frightened — a barrister's trick, he'd said, for witnesses coming apart on the stand. One, steady. Two, steady. The crescent scar on her wrist caught the moonlight as she pushed her sleeve back to cup the Heartstone in her palm, and for a moment she let herself look at that small white mark instead of the trees, because the trees were wrong in a way she couldn't yet name. Then she looked up, and she named it. They were too close. She had walked maybe fifteen paces into the grove. The ring of oaks should have been fifteen paces further from her than when she'd entered. Instead, the nearest trunk stood where it had been at the boundary, directly behind her right shoulder. And the one to her left — she was sure, she was almost sure — had been further off. Her mouth went dry. "Alright," she whispered, and the word disappeared as soon as it left her, with no echo, no carry. "Alright. Think." Something laughed. It wasn't a laugh exactly. It was the shape of a laugh, a soft exhalation with a lilt to it, the way someone might breathe out through their nose at a private joke, and it came from perhaps six feet behind her. She turned so fast her ankle rolled in the soft earth. Nothing. Only the oaks, and the flowers, and the moon painting everything silver and blue. The pendant against her sternum gave one hard throb, so warm now it was almost uncomfortable, and then settled into an urgent little rhythm, tap tap tap, faster than her pulse. She began to back toward the nearest stone. Slowly. She did not run. Running was how prey announced itself, she knew that much — she had learned it in a flat in Cardiff, she had learned it with her shoes in her hand on a staircase at two in the morning, and the lesson had stayed. Movement, at the left edge of her vision. She did not turn her head. She used the trick from those long bad months: watch the periphery without giving yourself away. Something had shifted between two of the oaks — something tall, or something that had been tall and was now hunched, the paleness of it too steady for a trick of light. When she let her eyes drift fully toward it, it wasn't there. Of course. She resumed her careful backward steps. The grass whispered now, at last, under her heels. That should have been a relief. It wasn't. The whispering had a cadence to it she didn't like. Not the brush of boots. A susurrus. Like speech the shape of which had been sucked out, leaving only the sibilants behind. Ssss, said the grass. Ssss. Ssss. "I'm leaving," she said, louder. "I came — I'm sorry — I didn't mean to be here." She had not planned to apologize. It came out of her anyway, and she hated the sound of it, the small girlishness of it, the instinct that had kept her alive once and which might be about to get her killed. She set her jaw. The oak at her back was cold through her jacket. She pressed her spine to it and made herself breathe. One, steady. Two, steady. The stone — because up close she could feel it was stone, not wood, though it grew rings and bark like a tree — hummed faintly, a deep patient note she felt in her teeth. Across the clearing, on the far side of the pooled moonlight, one of the flowers bent. No wind. It bent toward her, slowly, the way a person leans to listen. Then the one beside it bent. Then the next. A soft, rippling attention traveling across the grove in a wave, foxglove after foxglove, meadowsweet after meadowsweet, every pale bloom tipping its face her way. The laughter came again. Closer this time. At her ear, almost. A woman's laugh, warm and amused, as if she had just done something charming. Rory closed her fingers around the Heartstone so tightly the chain bit her neck, and it was pulsing hot now, hot as a held ember, and she thought, very clearly, with the cool part of her mind that had always saved her: *Whatever you are, I see you. I see you now.* A whisper, so close it stirred the hair at her temple: "Then, little one. Stay."
