You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

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. </instructions>

The gate to Richmond Park was chained at dusk, so Rory went over the wall by the deer fence, where the brick had crumbled into a foothold. Her palms came away smelling of moss and old rain. "Right," she said to nobody. "In, look, out." The bracken swallowed the path within twenty paces. She kept the torch low, a wobbling coin of light on wet ground, because a light held high in an empty park announced itself for a mile in any direction, and she had no interest in explaining herself to a park warden at half eleven at night. Her breath went out in slow ghosts. Somewhere off to the left, a stag coughed — that hoarse, wrong noise they made in the rut, like an old man dying in another room. She'd walked this way in daylight twice. Both times she'd found nothing but hawthorn and a dead badger. Tonight the pendant had started up in the taxi, a small crimson heat against her sternum, and by the time she crossed the second bridle path it had gone warm enough that she pulled the chain out from under her jumper and let it hang free. The stone glowed. Not much. Enough to lay a thin red wash over her knuckles. "You could have done that on Tuesday," she muttered. "Saved me a fiver." The oaks came out of the dark all at once, the way a face comes out of a crowd. Eight of them, or nine — she'd never got the count to agree with itself — standing in a rough ring with their bark split and folded like flesh grown over a wound. Between two of them the ground changed. Grass on her side, matted and frost-bitten. Wildflowers on the other, cornflowers and campion and something with a white bell she had no name for, all of it open and wide-awake in the middle of November. Rory stopped at the boundary and listened. That was the first wrong thing. In the grove, in daylight, there had always been sound: bees at that impossible ridiculous height of them, wind moving through the flowers, a stream she'd never located. Now there was nothing. Not silence exactly. Silence had texture. This had the flat deadness of a room with the door shut and the carpet up, and her own pulse came back at her too loud, as if the air had nowhere else to put it. She stepped through. The cold left her. That always happened, and she'd got used to it, and tonight she hated it — the way the sweat on her back went from ice to nothing between one footfall and the next. She turned the torch off. The grove had its own light, a low grey shine that seemed to come up out of the grass rather than down from the sky, and the sky above the ring of oaks held stars in the wrong places, too many of them, packed like grit. "Isolde," she said. The name did not carry. It fell about a metre from her mouth and stopped. She tried again, louder, and her voice came back to her a half-second late — not an echo, because echoes came from a surface and there was no surface, but a repetition, thin, further off, in a tone she hadn't used. Interested. As if someone had heard the word and tried it out for themselves. Rory kept still for a long moment. Then she crouched, set her bag down, and began doing what she'd come to do, because the alternative was to stand there and think about it. Salt in a line across the bare patch of earth. The little brass dish. The scrap of ribbon with a knot in it that Silas had pressed into her hand while saying, very clearly, that he wasn't giving her anything and hadn't seen her all week. She laid them out and her hands were steady and the pendant lay hot against her breastbone, pulsing now, quick, a rabbit heartbeat. "Isolde. It's Aurora Carter. You said if I ever needed—" Behind her, something walked through the flowers. Four steps. Unhurried. The stems bent and whispered and let go. Rory did not turn around. She had grown up with a man who liked her to turn around, who liked the flinch, and she had trained the flinch out of herself in a bedsit in Whitechapel over eight months, and now she used it. She finished setting the brass dish square. She breathed out. "You're early," she said. "Or I'm late. Hard to tell in here." Nothing answered. The flowers stood upright again in a curved line, four bruised places, leading from the standing stones to a point about three metres behind her left shoulder. She could see them in the corner of her eye without moving her head. She could also see that they had stopped there, and that nothing stood in them. The pendant went cold. All at once, like a hand closing over it. The warmth drained out of the stone so fast that the skin beneath ached, and its light died, and the grove darkened by a shade she hadn't known it was providing. "Okay," Rory said. "Okay." She reached for the torch. Her fingers found the grass where she'd put it down. Then more grass. Then the flat of her palm went over the bare earth, over the salt, and smeared it. She looked. The torch was four feet away, in the flowers, standing upright on its end like a fence post. Something laughed. Not near. That was the worst of it — the sound came from beyond the oaks, out where Richmond Park should have been, out where there were car parks and a rugby club and a Tesco eleven minutes' walk from the gate, and it was small and delighted and high, a child's laugh, the kind you heard from the top of a slide. It went on a beat too long. Then it stopped, mid-breath, cut off the way a radio cuts off. Rory stood up slowly with the ribbon in her fist. "I know you can hear me," she said. "I'm going to walk back out through those stones. I'm not taking anything, I'm not leaving anything, and I'd like it understood that I asked politely." The grass sighed. All of it at once, a long ripple crossing the clearing from the far side towards her, and there was no wind, she could feel there was no wind, her hair hung dead against her neck. She walked. Not fast. Fast was an invitation; she'd learned that from the man in Cardiff too. Eleven paces to the gap between the two oldest oaks, and she counted them, and on the seventh she saw the shape. It stood between the stones. Where she was going. Tall — taller than the gap should have allowed, so that the head was lost somewhere in the branches — and thin, and the grey light went through the edges of it the way it went through the flowers, and it had no face that she could find, though she looked, and the looking took something out of her that she felt leave, physically, like blood. Rory stopped on the eighth pace. "Move," she said. It didn't. The stars behind it crawled. And then, from the middle of the grove, from precisely the place where she'd been kneeling ten seconds earlier, her own voice said: "Isolde. It's Aurora Carter." Interested. Trying it out.
