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 gate to Richmond Park was supposed to be locked at midnight. It wasn't. Rory noticed that first — the chain coiled neatly on the ground beside the post, as if someone had set it down carefully, the way you'd put away a tool you intended to use again. She told herself it was nothing. Groundskeepers got lazy. Teenagers got in. London was full of small, explicable crimes against signage. The Heartstone pendant pulsed against her sternum, warm as a held breath. She'd found the envelope on her doorstep three days ago. No name, no return address, just a silver chain wrapped in tissue paper and a crimson stone the size of her thumbnail, glowing faintly from within like an ember that refused to die. The note had been a single line in cramped, slanted handwriting: *Go to the grove in Richmond. The night of the new moon. Wear it.* She should have thrown it away. She knew that the way you know a stove is hot — abstractly, until you touch it. But the pendant had done something to her, or she'd done something to it. On the bus ride here it had gone from cool to warm to almost hot against her skin, and when she'd stepped off at the park's edge it had flared so sharply she'd gasped out loud, and a man walking his dog had turned to look at her. Now, walking the black length of path with her phone flashlight trembling in her fist, it throbbed in a rhythm she was starting to suspect wasn't hers. Slower. Older. Like something enormous breathing far beneath the ground. The park at night was wrong in ways she couldn't immediately name. She'd walked here before, daytime, Eva beside her complaining about the price of coffee. The paths had felt open then, casual, dotted with joggers. Now the trees leaned over the trail in a way that felt less like geography and more like attention. The wind moved through the upper branches but not the lower ones, so the sound came from above her while the air at her face stayed dead still. Her footsteps were too loud. Then, after a hundred meters, they were too quiet — muffled, as if the ground were absorbing them, keeping them. The pendant pulled left. There was no path left. There was a stand of oaks, dark and patient, and between two of them — she was almost sure it hadn't been there when she'd looked a moment ago — a gap, a corridor of clear air through the trees. Wildflowers grew along its edges. She stopped walking and stood very still, her breath fogging, and stared at them. It was January. She could see her breath. The flowers were blooming anyway — small white ones, five-petaled, open and dew-wet, swaying gently in a breeze she could not feel. Rory had delivered food to every weird corner of London for two years. She had knocked on the doors of flats that smelled like incense and worse, had once carried sixty pounds of noodles up nine flights to a man who paid entirely in coins. She was not easily rattled. But standing there looking at impossible flowers in dead winter, she felt something in her animal brain sit down and start to cry. She went in anyway. She would spend a long time afterward wondering why, and the only answer she'd ever have was that the pendant wanted her to, and she'd worn it, and that was the whole of it. The corridor through the trees was short. It opened into a clearing ringed by standing stones — she counted nine before she stopped counting, because they weren't all where she'd counted them. They were oak, which was its own wrongness; stones that had once been trees, or trees pretending to be stones, their surfaces carved with grain and knots and what might have been faces if faces could be made of weather. Wildflowers carpeted the whole clearing, white and luminous under her phone's light, and the sky above was full of stars in a pattern she did not recognize — too many, too bright, arranged in spirals that hurt to look at directly. She checked her phone. 12:14 a.m. She watched the numbers. They did not change. She watched them for what felt like a full minute, her pulse ticking in her ears, and the screen still read 12:14, and the battery icon was full even though it had been at forty percent when she'd left the flat. "Okay," she said, aloud, because her voice was a thing she could control. "Okay. Reason it out." She'd come here for a reason. The note. The pendant. She turned in a slow circle, looking for what she was supposed to find — a person, an object, a door. The clearing was empty. The stones stood in their ring like an audience waiting for a speaker to begin. Then she heard the footsteps. Not hers. She was standing still. They came from the trees on the far side of the clearing, unhurried, soft on the flower carpet, and they matched her own stride exactly — she knew because she'd been listening to her own footsteps for twenty minutes and these were the same weight, the same slight drag of her left boot with its worn heel. They circled the clearing just inside the treeline. Rory turned with them, and never once saw anything, though the flowers at the edge of her vision bent and sprang back, bent and sprang back, in a slow procession around the ring. "Hello?" Her voice came out smaller than she intended. The footsteps stopped. The silence that followed had texture. It pressed on her ears like water. "Rory." Her whole body locked. That was Eva's voice. Perfectly Eva's voice, the particular Cardiff-softened lilt, the way Eva said her name with the last syllable lifted like a question. Except Eva was in London, in her flat, asleep, and this voice had come from everywhere at once — the stones, the ground, the flowers, the space behind her own teeth. "Eva?" she whispered. "You came." Warm. Pleased. From the left now, though nothing had moved on the left. "We've been waiting such a long time. Come closer, love. It's cold out." Rory did not move closer. She had spent two years learning, muscle by muscle, what it felt like when someone wanted to position her — a hand at her elbow, a voice that said *come here* like it was kindness. Evan had sounded kind. Evan had always sounded kind. Her thumb found the crescent scar on her left wrist without her deciding anything, an old habit, an old wound, and she pressed down on it until it hurt. "How do you know that name?" she said. The flowers turned. All of them, all at once, every white bloom in the clearing rotating on its stem like a field of small pale faces, orienting on her. It made no sound at all, and that was somehow the worst thing yet — hundreds of flowers moving in perfect silence, the way a crowd turns to watch. "Rory," the voice said again, and now it wasn't Eva's. It was Evan's. Exactly Evan's, the low patient tone he used when he was explaining, for her own good, all the ways she'd disappointed him. Her stomach dropped through the floor of herself. "You always were too clever to be safe. Come here. I only want to talk." "I'm leaving," she said, and her voice cracked on both words, and she didn't care. She turned toward the corridor between the stones — the way she'd come — and the corridor was gone. Not blocked. Gone. The ring of stones had closed behind her, nine or ten or thirteen of them, shoulder to shoulder now, their carved faces all angled inward, all of them looking at her, and the trees beyond them had drawn together like a curtain drawn by a slow hand. The pendant burned. She looked down and the crimson gem was bright now, lit from within, and its light fell on the flowers around her feet and every bloom it touched turned its face up to her, open, waiting, adoring. "Rory," said the voice, from directly behind her, close enough that she felt warmth on the back of her neck, warm as a held breath. "You put on the necklace. That's all the invitation we needed. You came in yourself." She did not turn around. Some deep, animal certainty told her that whatever stood there had no face yet — that it was waiting, patiently, the way the whole grove was patient, for her to look so it could finally decide what to show her. Her phone flickered. 12:14. 12:14. 12:14. Then, very quietly, the screen went dark, and in the black mirror of it, held low at her hip where she could see it without turning, there was a reflection of the clearing that had nothing to do with the clearing around her — a reflection in which the flowers were teeth, and the stones were taller, and the shape behind her was not shaped like anything she had a word for. Rory stood very still in the ring of stones, in the grove between the worlds, and began — calmly, methodically, because it was the only thing she had left — to think her way out.
