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 gates of Richmond Park closed at dusk, which was exactly why Rory climbed the fence instead. She'd told herself she wouldn't. All through the bus ride from Silas' bar, delivery bag still slung over her shoulder, she'd rehearsed the sensible version of the evening: go home, sleep, forget the pendant. But the pendant had other ideas. It had been warm against her sternum for three days now — not body-warm, not fever-warm, but warm like a stone left too long in direct sun, and tonight the warmth had become a pull. A direction. She'd felt it through her coat like a compass needle trying to bore through fabric. Now she followed it across the dark grass, her breath fogging, the city glow swallowed behind the treeline. Frost silvered the ground. December in London, and the frost was right, the cold was right, the skeletal trees were right. The pendant wasn't. It pulsed now. Faint, rhythmic, like something with a heartbeat pretending to be jewelry. The trees thickened as she walked, and Rory caught herself doing the thing she always did in situations she couldn't control — narrating. *You are Aurora Carter, twenty-five, employed, reasonably intelligent, walking through a public park at half eleven at night because a necklace told you to.* She said it silently, like a spell against the dark. It didn't help much. She almost walked past the stones. That was the strange part — her eyes slid over them twice before they landed. Six of them, arranged in a rough arc where the woods opened into a clearing, and they looked like oak trees that had forgotten how to be trees. Tall, grey, bark-furred, but hard as quarried rock, their surfaces carved with whorls that might have been knotwork or might have been faces that had never quite committed to being faces. The pendant flared hot against her chest. "Okay," Rory whispered. "Okay. This is the place." She stepped between two of the stones, and the temperature changed. Not warmer — that would have been a mercy. It changed the way a room changes when someone stops talking. The frost was gone. The air hung thick and green and wrong, like a greenhouse at midnight, and the clearing beyond the stones was in bloom. Wildflowers. Hundreds of them, thousands, a carpet of them stretching back into a darkness that shouldn't have been possible — the clearing was small, she could see its far edge, and yet her eyes insisted the flowers went on much farther than that. Primroses in December. Bluebells nodding in air that didn't stir. They were beautiful the way a smile is beautiful when you know it's lying. Rory checked her phone. 23:47. She watched the screen for a full minute, counting under her breath, and the digits didn't move. She closed her eyes, opened them. Still 23:47. The minutes had stopped, or the phone had, or the clearing had decided that time was optional, and Rory felt the first cold finger of genuine fear walk down the back of her neck. She should leave. Every rational part of her said so. But the pendant was pulsing faster now, tugging at the chain around her throat, and the crimson stone had begun to glow — a faint inner light, like an ember behind smoked glass. It wanted to go deeper. It had brought her here for a reason, the way the warmth had brought her across London, and Rory had learned in twenty-five years of being Aurora Carter that the things that wanted her rarely announced themselves politely. She walked in. The flowers turned. She didn't see them turn. That was the worst of it — she saw them before, facing away, and she saw them after, facing her, and her mind refused to assemble the two images into motion because motion meant they had watched her decide to come closer. She kept her eyes fixed on the middle distance and kept walking, boots silent on soil that gave too gently, like walking on the skin of something sleeping. The sound started on her left. Footsteps. Not hers. Hers had stopped — she'd halted mid-stride to be sure — and the footsteps continued for two more beats before stopping too, a half-second out of rhythm, the way an echo is always slightly behind the sound that made it. Except echoes don't land on frostless earth with weight behind them. "Hello?" Her voice came out wrong. Small. Swallowed. The clearing answered with birdsong. One note, bright and liquid, from somewhere above her. Then a second note, answering the first, from the opposite side. Then a third, and a fourth, from every direction at once, a chorus building in the black air — and Rory looked up and saw no birds. Not one. Not a wing, not a shape, nothing but a darkness that went up farther than any park sky should go, and the song went on anyway, sweet and layered and utterly delighted, the sound of something imitating a morning it had only ever heard described. The pendant burned now. Not painfully — worse than painfully. Gently. A warmth spreading across her collarbone like a hand laid flat against her skin, and Rory understood with a lurch that it wasn't warning her anymore. It was answering. She turned in a slow circle, and at the edge of her vision, at the very rim where sight gives up, something tall stood between two of the standing stones. She snapped her eyes to it and found only stone. Turned her head, and there it was again — tall, thin, patient, one arc over. She stopped turning. It was in the corner of her eye no matter which way she faced, which meant it wasn't circling her. It was everywhere she wasn't looking. Her left wrist ached. The little crescent scar, the one from the greenhouse when she was nine, throbbed in time with the pendant's pulse, and Rory pressed her thumb over it hard enough to hurt because pain was real, pain was from before, pain belonged to a world with clocks in it. The birdsong stopped. All of it, at once, mid-note. In the silence she heard her own name. Not spoken. Breathed. *Rory.* From behind her, close enough that she felt warmth on the back of her neck, and it was her own breath's warmth, her own shape of sound, her own voice returned to her a half-second late — the footsteps, the echo, the clearing learning her, and Rory stood absolutely still because the voice was very close and she did not know what she would see if she turned around and she was not willing to find out. The flowers had closed behind her. She saw it without turning: the carpet of blooms, the beautiful lying smile of them, now pressed flat and shut in a solid ring around her, and beyond the ring the standing stones had moved. They had been an arc. They were a circle now. Every gap she'd walked through was filled with grey bark and carved whorls, and the whorls had committed. They were faces. They had been faces the whole time, watching with the patience of wood, and one of them — she could see it plainly now, no longer at the edge of anything — was smiling. The pendant's glow lit her chin from below, crimson, steady, almost tender. *You brought me here,* Rory thought, at the stone, at the grove, at the thing breathing her name in her own voice behind her. *You've been leading me the whole time.* The breath on her neck came again, warmer. *Rory,* it said, and this time it added something after her name, softly, in a language with no human consonants in it, and the flowers all around her opened at once — every bloom, every petal, turning inward toward her like a thousand small red eyes. She turned around. Her phone said 23:47. The darkness behind her was not empty.
