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 at Richmond Park had been chained since sunset, so Rory left the scooter in the bushes off Sawyer's Hill and went over the wall the way Eva had shown her, palms flat, one leg swung, drop and roll. Her ankles took it badly. Twenty-five years old and already her body kept a ledger. She checked her phone at the bottom of the slope. 11:47. Battery at sixty-one percent. No signal, which was normal here, or normal enough that she didn't let it mean anything yet. The grove was a half-mile in, past the bracken, past the stand of dying sweet chestnuts that always smelled faintly of cider. Isolde's message had come the way her messages always came — folded into the lining of Rory's jacket pocket, on paper that felt like the inside of a flower petal, in handwriting that made her eyes ache if she looked too long. *Come to the grove. Alone. Before the moon touches the tallest stone.* Rory hated the alone part. She hated the deadline more. Fae never gave deadlines unless something was already going wrong. The deer watched her go by. That was the first thingnot wrong, exactly, but noted. There were four hundred and something red deer in Richmond Park and they were used to people, bored by people, but they didn't usually stand like that. Eight of them in a loose row along the ridge, heads up, ears forward, all facing the same direction. Not facing her. Facing the way she was going. "Right," she said aloud. "Great. Thanks." Her voice didn't carry the way it should have. It went out of her mouth and stopped about a yard away, like she'd spoken into a coat. The standing stones came up out of the dark before she expected them. Nine slabs of grey oak, petrified, older than the park, older than the city, arranged in a ring the size of a tennis court and set so deep in the earth that the grass had grown up their sides like water. Between them the wildflowers were doing their impossible thing — cornflowers and foxgloves and something white and bell-shaped in mid-February, glowing faintly the way pale things do at night. Rory stopped at the boundary and did what she always did. She counted the stones. Nine. She stepped through. The temperature changed. It always did — a soft pressure-drop, like walking into a church, and behind her the noise of the world went away entirely. No A308. No planes stacking up over Heathrow. The silence had a shape to it, a curvature, as though she stood inside a bowl turned upside down. And under her collarbone, the Heartstone woke up. She felt it before she understood it: warmth, the specific animal warmth of a hand laid flat on skin, spreading out from the crimson stone at the base of her throat. She dragged it out of her shirt. The gem was glowing — not faintly, not the usual ember-in-a-dark-room suggestion of light, but properly glowing, pulsing in a slow rhythm that did not match her heartbeat, and each pulse pushed heat up into her jaw. Rory stood very still. The pendant only did that near a Hel portal. There was no Hel portal in Richmond Park. There couldn't be. The grove was Fae-touched, sealed, older than any of that; Isolde had explained it once with the patient contempt she reserved for humans asking about plumbing. Two systems, two separate systems, no interface. "Isolde," Rory said. Nothing answered. The wildflowers moved, and there was no wind. She turned in a slow circle, keeping the pendant cupped in her fist so the light didn't ruin her night vision. Empty clearing. Grass silvered. The tallest stone at the north end with the moon still a hand's width off its crown, so she was on time, she was early, she had done everything right. The sound came from her left. A small metallic *ting-ting* — two notes, cheap and bright. The bell over the door of the Golden Empress. Rory's whole skin tightened. She heard it again, three seconds later, and with it, faint as a memory but not a memory, because memories didn't come from *outside your head*: the extractor fan, the clatter of a wok, Yu-Fei shouting an order number in Cantonese. Kitchen noise. Warm, greasy, familiar kitchen noise, thirteen miles away, coming out of a hedge of hawthorn at the edge of an empty field at midnight. "No," Rory said. She said it firmly, the way you'd correct a dog. "That's not there." The noise stopped mid-clatter. Cut, not faded. Like a hand over a speaker. The quiet afterward was much worse. She began to walk — not toward the sound, not running either, just moving, because standing in one place had started to feel like being on a plate. Halfway across the clearing something crossed the corner of her eye at the tree line: a vertical smear of pale, upright, tall, gone by the time her head came round. She stared at the gap between two oaks. The gap stared back. She counted to twenty. Nothing moved. Somewhere behind her, on the opposite side of the ring, a stick broke with a wet crack, and she did not turn around. She'd read about this once, in a psychology module she'd taken to pad her Pre-Law timetable. Hypervigilance manufactures its own evidence. The brain in a dark wood will build a face out of any three points of light. Fine. Except the brain did not manufacture the Heartstone, and the Heartstone was so hot now that it had left a mark on her palm. "Isolde." Louder. Her voice still went nowhere. "This isn't funny. If you're—" "Rory." She stopped breathing. It was Eva's voice. Eva, who was asleep in Bethnal Green, who had never once been to this grove, who did not know it existed. Eva's exact voice, with Eva's exact stupid rising lilt on the second syllable, the one she used when she'd found something funny on her phone and was about to make Rory look at it. It came from about six feet behind her, at roughly the height of a person's mouth. "Rory, come here." Every instinct in her body wanted to turn round, and Rory understood — with a clarity that arrived cold and complete, the way answers sometimes did, the way they had the night she'd finally walked out of Evan's flat with two carrier bags and a broken wrist splinted in a tea towel — that turning round was the single thing she must not do. She looked at the ground instead. At her own shadow, laid out ahead of her by the pendant's crimson light. There was another shadow behind it. Attached to hers at the heel. It was thinner than a person. It was taller than the stones. "*Rory.*" She started walking. Not toward the voice. Toward the boundary, one foot then the other, at the pace of someone crossing a road, because she had a horrible certainty that if she ran, permission would be granted for something to give chase. The grass hissed at her shins. The pendant burned. Behind her, the thing said her name again, and then it said it in her mother's voice, and then in Yu-Fei's, and then in her father's, and then in her own — perfectly, warmly, patiently, working through everyone who had ever loved her like a man trying keys in a lock. The stones came up. She put her hand on the nearest one and it was cold as a fridge door and she nearly sobbed with relief. Then, because she was Aurora Carter, and because she could never in her life leave a thing unchecked, she looked along the ring and she counted. One. Two. Three. Four. Five. Six. Seven. Eight. Nine. Ten. The tenth stone stood between two oaks where there had never been a stone, grey and vertical and rooted, patient as geology. It turned its head.
