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 should have been locked. Rory stood with her hand on the cold iron and stared at the open dark beyond it, her breath smoking in the September air. The last delivery for the Golden Empress had run late, a double order of dan dan noodles out to a flat in Ham, and Yu-Fei had pressed a ten pound tip into her palm and told her to get home safe. She should have been home by now, up the narrow stairs above Silas' bar with the kettle on and her dead phone on charge. Instead she was here, because Eva had left a voicemail at eleven forty with nothing on it but wind and then, very faint, Eva saying come to the grove, Rory, come quick. She had tried to call back three times on the ride over. No answer. She wheeled her bike through the gap and the gate clicked shut behind her on its own weight. The sound carried too far. Richmond Park at night was not silent. Rory knew that. Even at one in the morning there should have been traffic humming off the A3, a plane dragging toward Heathrow, a dog fox barking, the chuck of gravel under the wardens patrol. What she heard was her own trainers on the path and nothing else. No cars. No wind in the high branches. London had been switched off. She tucked her straight shoulder-length black hair behind her ears to hear better and the ends caught damp against her neck. Her bright blue eyes took a long moment to adjust. The path ran pale between black grass, straight and then bending, and the trees leaned over it in a way she did not remember from daytime. She had only been to the grove once before, in high summer, when Eva had dragged her out with cheap cider and shown her the place between the old oaks where the city fell away. Eva had called it Isolde's grove. Rory had laughed at the name until she stepped past the ring of standing stones and felt the temperature change on her skin, until she saw the wildflowers thick underfoot in a place that should have been trodden mud. Now she followed the memory of that walk, counting her steps the way her father Brendan had taught her to count arguments, point by point, to keep herself steady. Cool head. That was what people said about her back in Cardiff, before Pre-Law and Evan and all of it. Cool-headed Rory. The pendant thumped once against her sternum. It was a small thing, roughly the size of her thumbnail, a deep crimson stone on a silver chain, left in an unmarked envelope at the bar two weeks ago with her name written in a hand she did not know. She had meant to take it to a pawn shop. She had not. Tonight it gave off a faint inner glow, just enough to light the hollow of her throat when she looked down, and it was warm. Not from her skin. Warm from the inside, pulsing slow like something with a heartbeat. She closed her fist around it and kept walking. The air changed first. It grew sweeter, heavy the way greenhouses were heavy, with crushed stems and pollen. Her torch beam caught color where there should have been none. Wildflowers. That same dense mat she remembered from July, cowslips and ragged robin and tiny white stitchwort, all open. At night. In autumn cold. Their heads were lifted toward no sun, beaded with dew that caught the light and threw it back too brightly. The smell rose up and coated the back of her throat and made her think, suddenly and sharply, of her mother Jennifer in their small garden in Cardiff, humming while she deadheaded roses. Rory stopped. She rubbed at the small crescent-shaped scar on her left wrist without thinking, a childhood kettle burn she always touched when she was trying not to panic. The standing stones rose out of the dark ahead. They were not proper stone, not really. That was what unsettled her. Each one stood as tall as she was and then more, Rory was five six and she had to tip her head back to see their tops, and their surfaces were ridged and furrowed like ancient oak bark, black with wet moss in the grooves. Someone had set them in a loose circle a long time ago, and the ground inside the circle was bare except for those flowers. Beyond them the trees pressed close and then stopped, as if warned off. She stepped between two of the stones and her phone clock flickered. One fourteen. Then one thirteen. Then one fourteen again. She stared at it. She turned the brightness up, down. The signal bars were gone. Not low. Gone, as if the phone had forgotten what signal was. She slipped it into her jacket pocket and told herself, out loud and quiet, that it was a dead spot. Her voice sounded wrong to her, flattened, as if the clearing had absorbed the edges of it. Eva, she called. Eva? No answer. Then, a half second later, something answered the crunch of her own foot shifting on gravel. It was behind her and slightly to the left, a single soft displacement of small stones, timed just off enough from her movement that she could not pretend she had made it. Rory went very still. She listened the way Evan had once taught her to listen for his key in the lock, with her whole body. Nothing. Then the flowers moved. There was no wind, she was sure there was no wind because her hair hung straight and cold against her cheeks and her breath went straight up, but a ripple passed through the wildflowers from the edge of the circle inward, stem by stem bowing and rising though nothing touched them. The sweet smell sharpened until it was cloying. The pendant pulsed hotter against her chest, a distinct throb of warmth that spread through the silver chain. She thought of the envelope. No note. Just the stone, winking crimson in tissue paper. She backed up a step, keeping inside the stones because some old instinct told her the boundary mattered, and swept the torch slow around the treeline. The beam shook. She locked her wrist with her other hand to steady it, annoyed at herself, thinking fast. If Eva was hurt out there she would have called out again. If this was someone messing about, the light would catch them. If it was neither, she needed a way out she could find blind. The light slid over trunks, wet leaves, one of the oak stones. And between two trunks, for less than a blink, something tall stood where no tree had been. She jerked the beam back. Nothing. Only dark and the press of branches. But at the edge of her vision, to the right, a paleness detached itself and was gone when she turned her head. Her peripheral vision prickled. She had the sudden, childish certainty that if she looked directly at it, it would stop pretending to be trees. Another sound then, and this one lifted every hair on her arms. Humming. Low and tuneless, a woman humming under her breath while she worked. It came from everywhere and nowhere, thread thin, and for one terrible moment it sounded exactly like her mam in that Cardiff garden, and then it bent. The notes stretched too long. The pitch dropped a fraction lower than a human throat should comfortably go, and kept dropping. Rory swallowed. Her mouth was dry. She said, very clearly, Who is there. The humming stopped. The silence that followed was worse because now she could hear the second silence underneath it, the one that had been there all along. A held breath. A patience. The flowers bowed again, closer this time, a handspan from her trainers. The pendant was almost hot now, its faint glow bleeding through her T-shirt, crimson as a coal. She understood, with the quick out-of-the-box clarity that had once gotten her through moots she had not prepared for, that the stones were not keeping something out. They were marking where it was allowed to be thin. She was standing in the middle of a pocket worn between one world and another, and time here was not London time, and the gate clicking shut behind her might have been minutes ago or days. Behind her, gravel crunched again. Deliberate this time. Two steps. Stopping just outside the circle. She did not turn around. She stared straight ahead at the dark between the oak stones where the white flowers glowed faintly, and she watched in the very edge of her sight as a long shadow leaned in, curious, learning the shape of her.
