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 oaks marked the boundary the way headstones mark a grave — old, weathered things standing sentinel in a circle that Rory had walked past a hundred times in daylight without ever once feeling their weight. Tonight she felt it. Tonight the standing stones seemed to lean toward her as she passed between them, as if the whole grove had turned its face to watch her come in. She hadn't wanted to come at night. But the pendant had gone warm against her collarbone around ten o'clock, warmer than she'd ever felt it, and warmth meant a portal, and a portal near Richmond Park meant something was wrong enough that waiting until morning felt like a luxury she couldn't afford. The grove at night was not the grove she remembered. In daylight it was soft-edged and golden, wildflowers nodding in a breeze that never seemed to touch the rest of the park, the kind of place that made you forget you'd come in on a whim to test whether the old stories Eva told her were true. Now the flowers were closed fists, black against black grass, and the air had a stillness to it that felt deliberate, like a held breath. Rory stepped further in. Her boots made no sound on the grass. She noticed that first — properly noticed it — three steps past the stones, when she stamped down hard just to hear something and heard nothing at all, not even the wet give of turf underfoot. She stood there a moment, foot still pressed into the ground, and told herself the grove muffled sound the way it muffled time. That was the deal. An hour here could be a day out there, or ten minutes. Sound could be strange too. That was just how it worked. She didn't believe herself, but she kept walking anyway. The pendant pulsed against her skin, a slow heartbeat of warmth that quickened as she moved deeper toward the center of the clearing, where Isolde had told her, once, that the veil between worlds hung thinnest. Isolde wasn't answering her calls tonight. That was the first wrong thing, if she was being honest with herself — the second, really, after the silence under her boots — and she'd chosen not to dwell on it back in her flat, in the warm circle of lamplight, with Silas' bar humming faintly through the floorboards below. Out here, with nothing but moonlight and the black shapes of trees, the not-dwelling became harder to manage. Something moved at the tree line to her left. She turned fast, hand going to the pendant like it was a weapon rather than a compass, but there was nothing there — just the dark mass of oak and hazel, branches knitted too close together to let the moon through. She watched it a long five seconds. Nothing moved again. She told herself it was a fox, or a bird startled off a low branch, and she made herself walk on because turning back now, with the pendant this warm, felt like a worse idea than continuing. The wildflowers brushed her ankles as she passed, and she realized, with a small cold lurch, that she couldn't feel them. She stopped and crouched down and put her palm flat against a cluster of closed blooms, and felt only a vague pressure, like touching something through a thick glove. She stayed crouched there a moment, breathing. "Isolde?" she said, and her voice came out smaller than she meant it to, and stranger — it didn't carry the way a voice should in open air. It fell flat a few feet from her mouth, as though the grove had absorbed it before it could travel. No answer. Of course no answer. She stood back up. That was when she heard the second sound — not her own boots, not her own voice, but breathing. Slow. Even. Coming from somewhere behind her, or beside her, or perhaps from the trees themselves; it was impossible to place, the way all the other sounds here refused to sit properly in space. She went very still and listened, and for three or four full breaths of her own she heard nothing more, and thought perhaps she'd imagined it, the way you imagine footsteps behind you on an empty street. Then it came again. Closer. She turned in a slow circle, scanning the treeline, the standing stones behind her now smaller with distance, the open dark of the clearing ahead. Nothing. No shape, no shadow that didn't belong to a tree or a rock. But the breathing didn't stop, and now it seemed to come from more than one direction at once, soft and patient, as if whatever it belonged to had all the time in the world and knew that she did not. The pendant flared hot enough that she gasped and closed her fingers around it through her shirt. "Okay," she said, mostly to herself, mostly to keep her voice moving through the air even if the air refused to carry it properly. "Okay, that's — that's new." She began walking backward, toward the stones, refusing to fully turn her back on the clearing. The flowers didn't rustle beneath her feet. Her own breathing sounded too loud in her ears, ragged counterpoint to the slow, even thing she could still hear all around her, and she became certain — not afraid exactly, not yet, but certain in the way you're certain of gravity — that if she looked hard enough at any given shadow, it would resolve into something looking back. She didn't look hard. She kept her eyes moving, kept her feet moving, and did not run, because running felt like the thing that would invite whatever this was to stop being patient. The standing stones came up around her almost before she expected them, ancient oak sentinels rising out of the dark, and she felt something in the air change the moment she passed between two of them — a pressure equalizing, sound rushing back in a wash of ordinary night: distant traffic, wind in real leaves, her own boots suddenly loud and wet against actual mud. She didn't stop walking until she was well clear of the trees, out under open sky, the pendant cooling slowly against her skin, her heart going hard enough that she could feel it in her throat. Behind her, deep in the grove, the breathing did not follow. But she stood a long time at the edge of the park anyway, watching the dark gap between the oaks, waiting to see if anything would come out after her. Nothing did. That, somehow, was worse.
