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 on Sawyer's Hill was chained, so Rory went over the wall. She landed badly, wrong-footed in wet bracken, and knelt there a moment with her palm pressed flat to the cold ground, listening. Nothing. No torch beam swinging her way, no dog, no shouting park warden. Just the long exhale of Richmond Park at half past eleven, and somewhere far off the throat-clearing rumble of the South Circular, which was the last honest sound she'd hear for a while, though she didn't know that yet. She'd looked it up on the bus. Nine hundred hectares. Two and a half thousand acres. It had seemed like a number on a screen. Standing in it, in the dark, with the grass hissing against her jeans and no lamplight anywhere, it became something else entirely: a country. She was in a country, alone, at night, because a folded square of paper had appeared under her flat door with six words on it in handwriting she didn't recognise. *The grove. Moonrise. Come alone. Please.* The *please* was what had done it. Rory had spent two years learning to distrust politeness, and she still hadn't managed it. The pendant lay cold against her sternum. That was the other reason she'd come — the cold. For three weeks the Heartstone had been running warm as a fever, warm enough that she'd woken twice with the crimson gem branding a mark below her collarbone, and then on Tuesday it had simply stopped. Gone inert. A pretty red bead on a silver chain and nothing more. Whoever had left it for her hadn't included instructions, but she'd worked out enough to know that when a thing that warns you goes quiet, you don't relax. You start counting. The oaks came up out of the dark ahead of her like a decision someone else had made. Nine of them, in a rough ring, so old they'd stopped looking like trees and started looking like architecture — trunks split and buttressed, bark folded in on itself, limbs gone down into the earth and back up again. Standing stones with leaves. Eva had described them once, laughing, over the last of a bottle of Merlot, and Rory had nodded along and thought *right, sure, magic trees* and filed it under the enormous and growing folder in her head labelled things she'd deal with later. She stopped ten feet short of the ring. She hadn't meant to. Her legs had simply arrived at a conclusion before the rest of her. Because it was warm. Not the air — the air was February, raw and damp, and her breath went up in front of her in ragged white flags. But the grass inside the ring was dry. She could see it in the moonlight, pale and lush and moving in a breeze that wasn't touching her at all. Wildflowers, bobbing. Cow parsley, foxgloves, something small and blue in drifts. In February. In the dark. *One hour in there could be a minute out here,* Eva had said. *Or three days. Isolde's never been able to explain it properly. She says it's like asking a fish about swimming.* Rory stepped through. It was like putting her face into bathwater. The cold went off her all at once, and the sound changed — that was the part that got into her teeth. The traffic hum stopped. Not faded. Stopped, the way a radio stops, mid-word. And into the gap came the noise of the grove: insects, thick and layered, a summer sound, a July-at-dusk sound, and under it the trickle of water she couldn't locate, and above her a sky that had too many stars in it and had put them in the wrong places. "Right," Rory said out loud, mostly to hear her own voice work. It came out flat and small, as though the grove had taken the edges off it. "Okay. Hello?" The insects went on. She turned a slow circle. The clearing was maybe twenty metres across, and empty, and there was nowhere in it for anyone to hide, and the moonlight was strong enough that she could see individual blades of grass. Nobody. She'd known, walking in, that she was early or late — there was no way to be on time for anything here — but the *please* had made her expect a person. A woman with a warning. Someone to be furious at. She sat down on a fallen limb near the eastern oak, put her hands between her knees, and waited. It was fine for a while. That was the thing she'd think about afterwards, over and over: how long it was fine. Ten minutes, twenty. Her shoulders came down. The air smelled of hay and green sap. She caught herself almost enjoying it, the absurd warmth, the ridiculous stars, and she was reaching up to touch the pendant the way she'd got in the habit of doing when she noticed that the insect noise had a shape. It rose and fell. All of it, in unison — the whole seething mass of it swelling and dropping in a slow rhythm, maybe five seconds up, five seconds down. Breathing. It was breathing. Rory sat very still and listened to it do that eleven times, and did not move, and told herself that crickets probably did that, that there was no reason a chorus of insects couldn't synchronise, that bloody fireflies did it in Malaysia or somewhere, she'd seen a documentary. It didn't help. The rhythm was too slow. It was the rhythm of something enormous and unhurried, something asleep and not deeply asleep, and the insects were simply what it sounded like from inside. Something moved at the treeline to her left. She didn't turn her head. She had learned that, at least; Evan had taught her a great deal about the value of not reacting, of keeping her face smooth while she assessed exits. She held her gaze forward and let the edge of her vision do the work, and the movement resolved into a pale shape between two trunks, upright, roughly her own height, and it was not there when she finally allowed herself to look. A birch. A slim white birch, growing between the oaks. Rory looked at it for a long moment. Then she looked at the ring of oaks — nine of them, she'd counted nine coming in, she was certain — and counted, and got nine, and could not make the birch fit anywhere in that number no matter how she arranged it. She stood up. "I'm going to go," she said, to the clearing, in the pleasant, reasonable voice she used on customers who'd been kept waiting. "You said come, I came. If you want to talk, you can find me." The insects stopped. All of them, everywhere, at once — and the silence that dropped into the grove was not an absence of sound but a thing in its own right, thick, pressing, the silence of a room where somebody has just stopped speaking because you came in. Rory's ears rang with it. She could hear the blood in them. She could hear the small wet click of her own throat. And then, from behind her, from the direction of the western oaks and the way she had come, someone said her name. "Rory." Her whole body knew the voice before her mind would allow it. Her shoulders went up. Her stomach dropped into a cold pocket that had been waiting two years to receive it. *Evan.* Evan's voice, the soft one, the one he used after, the one that meant he'd decided to be kind — and it was impossible, it was three hundred miles and a locked door and a whole other life impossible, and it was *him*, right down to the small dry catch on the R. The pendant against her sternum flared. Not warm. Hot — a bright, sudden, disciplinary heat, the sort you'd use to snap a sleepwalker out of it, and Rory gasped and clamped her hand over it and felt the crimson stone pulsing under her palm like something with a heartbeat, fast, fast, fast. *Don't answer.* She didn't answer. "Rory." Closer now. Reasonable. Fond. "Don't be like this. Turn round." The grass had gone still. Every flower in the grove was pointing at her. She thought: it doesn't know my name. It knows a shape that gets me to turn round. And she thought, with a clarity that felt like ice water: whatever is standing behind me is standing between me and the way out. Rory did not turn round. She started walking — east, away from the voice, into the black gap between two oaks she had never seen the far side of, with her fist closed white-knuckled around a stone that burned, and behind her, in her own considered silence, something began to follow her at exactly the speed she walked.
