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 bike chain had stopped ticking three minutes ago, and Aurora only noticed now, standing at the treeline with her hand still on the cold saddle. That was the first thing. Not a sound. The absence of one. She'd left the bike leaning against a hawthorn at the edge of the car park and walked the last half-mile in, the way Silas told her to — no metal past the stones, no lights, no promises you can't keep. Richmond Park at two in the morning was a black bowl with London's orange smear along its rim, and it had been full of noise the whole way: the motorway breathing somewhere off to the north, an aeroplane grinding down toward Heathrow, the wet crunch of her own trainers in frostbitten grass. A stag had coughed at her from the dark near Pen Ponds and she'd nearly bitten through her tongue. Now there was nothing. She stood in the gap between two oaks — the standing stones, Silas had called them, though they weren't stone at all, they were trees older than the city, their trunks fluted and grey as pillars, their crowns long dead — and the world behind her had gone quiet as a held breath. Aurora turned around. The park was still there. The grass, the fence line, the far ridge of Sawyer's Hill. It looked exactly the way a photograph of a place looks: correct in every detail and entirely uninterested in her. She should have brought Eva. She should have brought anyone. "Isolde," she said. Her voice went out about six feet and stopped, as though it had walked into a wall of felt. She stepped through. The temperature changed on the second stride. Not warmer, exactly — softer. February let go of her face. The frost under her feet became grass, then flowers, and by the time she reached the middle of the clearing she was ankle-deep in cowslips and cornflowers and something with white bells that shouldn't bloom until May, all of them open, all of them nodding in a wind she couldn't feel. The moon was directly overhead. It hadn't been overhead four minutes ago. It had been low and thin and behind her left shoulder. Aurora made herself breathe. She'd sat across a table from a man who broke her ribs and told a magistrate about it in a level voice; she could stand in a field of wrong flowers. She had come for an answer. That was the whole of it. Three weeks of the pendant going warm in the strangest places — outside a launderette in Camden, in the stairwell of her own building, once against her sternum in the middle of a delivery so hot she'd dropped a bag of char siu in the road — and nobody would tell her why. Silas had said the grove listened. Isolde would come, he'd said, if Aurora waited and didn't ask twice. So she waited. The flowers nodded. The moon sat still. Aurora counted to a hundred, then to two hundred, and somewhere around a hundred and forty she understood that she couldn't hear herself counting, that she'd stopped saying it out loud at some point without deciding to. The pendant was cold. She'd checked it twice, thumb pressed to the little crimson stone, and it lay against her collarbone like any other cheap chain, its faint inner light dimmed almost to nothing. That was good. Cold was good. Cold meant no portal, no door standing open in the dark where a door had no business being. At two hundred and eleven, something moved at the edge of the clearing. She didn't turn her head. She'd learned that much on the streets around Soho at closing time: you don't turn, you look. She slid her eyes left and held them there and saw the tall grass at the boundary swaying, one narrow line of it, the way grass sways when something low has just gone through it. "Isolde?" she said. The grass stopped. Aurora stood very still and thought: deer. The park was thick with them. Six hundred of them, red and fallow, and they went where they liked. Then, from behind her, a sound she recognised so completely that her whole body understood it before her mind did — a soft double click, metal on metal, the noise a bicycle makes when the chain settles on the sprocket. Her bike was half a mile away on the other side of the stones. She turned. Nothing. Flowers, oaks, moonlight lying over everything like milk. "Right," she said, out loud, and this time her voice carried too well, sailing out across the clearing and coming back a half-second late, slightly altered, the way a recording of yourself never sounds like you. "Right. Okay." She started walking toward the stones. It took longer than it should have. She had come in maybe thirty paces; she counted forty going out, then fifty, and the two grey oaks stayed exactly the same size ahead of her, patient as ushers. The flowers pulled at her ankles. She thought about the delivery bag still strapped to her back — she hadn't wanted to leave it with the bike — and how absurd it was, how absurd she was, twenty-five years old and lost in a field with somebody's cold spring rolls. That was when she heard the breathing. It was behind her and slightly to the right, close enough that she felt she ought to be able to feel it on her neck, and it was not an animal's. It had a rhythm. It had the small catch at the top of each inhale that a person makes when they're trying not to be heard and enjoying the trying. Aurora stopped walking. Her heart went somewhere up into her throat and stayed there, beating hard enough to hurt. Don't ask twice, Silas had said. "Who's there," she said, and it came out flat and unafraid, which was the only gift her father had ever given her. The breathing stopped. In the silence that followed she became aware of the pendant. Not warm — not yet. Just no longer cold. A faint, patient heat, the temperature of a hand that had been resting somewhere a long time and had only now begun to press. Behind her, in the grass, something shifted its weight. And a voice said, "Rory." It was gentle. It was pleased. It had the small Cardiff lilt she'd spent seven years scrubbing out of her own mouth, and it was her mother's voice, exactly and completely her mother's voice, right down to the way it always went up at the end of her name as though asking permission. Her mother was asleep in a semi in Llandaff, three hours and a hundred and fifty miles away, and had never in her life set foot in Richmond Park. Aurora didn't turn around. Something in her, some old cold animal sense far below thought, told her that turning around was the last decision she would ever be allowed to make. The pendant grew warmer. "Rory," the voice said again, closer now, almost fond, "you've come such a long way." And out in the dark, at the treeline, all around the clearing, the tall grass began to sway — not in one narrow line this time, but in eight or nine of them, all bending inward, all moving toward the centre where she stood. Aurora Carter closed her hand around the pendant, and it burned.
