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 that marked the boundary stood exactly where they'd always stood, but Rory had never come to the Grove after dark, and she understood now, with the particular clarity of someone who has made a mistake and cannot yet name it, that she should not have come at all. Isolde had said midnight. Isolde had said the pendant would know the way. And so Rory had left the flat above Silas' bar at half past eleven, jacket zipped to her chin, the Heartstone a small cold weight beneath her collarbone, and crossed the sleeping expanse of Richmond Park with the particular stupid confidence of a woman who has survived worse than a dark park before. The pendant had been warm the whole walk. Now, ten feet past the standing stones, it went hot enough that she pressed her palm flat against her sternum, feeling it pulse through the fabric of her shirt like something with its own heartbeat. "Okay," she said, to no one, because the sound of her own voice was better than the sound of nothing. "Okay." The grove at night did not look like the grove she remembered from Isolde's one previous invitation, three weeks ago, in the buttery light of a Tuesday afternoon. Then, the wildflowers had nodded in a breeze that didn't exist anywhere else in Richmond Park, purples and yellows so saturated they looked painted on. Now the flowers were the wrong color — grey, all of them, drained of whatever light usually fed them, and utterly still. No breeze. No breeze at all, which struck her only after a full minute of standing there, because the ordinary world had wind and this place, tonight, did not. She started walking toward the center of the clearing, where Isolde liked to sit on the flat grey stone that jutted up like a broken tooth. Her boots made no sound on the grass. She noticed that too, filed it away next to the wind, told herself that fae places didn't play by regular rules, that Isolde herself had said as much — an hour in here could be a minute out there, or a week, and who was to say sound worked the same way. Halfway to the stone, she heard breathing. Not her own. She stopped, held her own breath deliberately to be sure, and there it was again, off to her left, slow and even, the exhale of something very large taking its time. She turned. Nothing but grey flowers and the black wall of the tree line, oaks packed close enough that their trunks made a kind of palisade, and beyond that, more darkness, unhelpfully patient. "Isolde?" Her voice didn't echo. It simply stopped, swallowed a foot past her lips, and that wrongness settled into her chest alongside the pendant's heat and did not leave. She made herself keep walking. The stone was closer now. No one sat on it. Of course no one sat on it — Isolde was fae, unpredictable, prone to arriving fashionably at whatever hour suited her whims, and midnight in a place where time didn't behave was hardly a fixed appointment. Rory told herself this in the reasonable, unhurried voice she used on frightened customers when a delivery ran late, and she almost believed it. The breathing came again. Closer. She spun, fast, the way Eva had taught her back when Eva was still teaching her things like *always know where the door is* and *never let him see you flinch*, and found the tree line exactly as empty as before. But something in the pattern of shadow between two oaks had changed — she couldn't say how, only that her eye kept sliding to that gap and finding it subtly different from the gaps on either side, deeper somehow, as though the darkness there had more of itself to give. The grass at the edge of her vision moved. Not blew. Moved, a long low ripple traveling through the grey stalks in a line too straight and too deliberate to be anything so ordinary as wind, arrowing from the tree line toward the point where she stood, and stopping, abruptly, ten feet away. She stared at the place it stopped. The grass there stood perfectly, unnaturally still, the way a held breath is still. "Right," she said, and her voice came out steadier than she had any right to expect. "Right, that's — that's fine. That's fine, Rory." She backed toward the stones. Not running. Running felt like the kind of decision that, once made, could not be unmade, and some old cold instinct told her that showing her back to the grove right now would be the worst mistake available to her. So she walked backward, slow, deliberate, eyes on the black gap between the oaks that had felt wrong from the first look. The pendant seared against her skin. She gasped, clapped her hand over it through her shirt, and in the half-second her attention dropped from the tree line to her own chest, the quality of the silence changed. It thickened. It gained a texture, like the difference between an empty room and a room where someone is standing very still just behind the door, and when she looked up the gap between the oaks was no longer a gap. Something filled it. Something the approximate size and shape of a very tall man, if a man could be made of the same absence of light as the space between stars, and it was not moving, and that was somehow so much worse than if it had been. She did not scream. She would think about that later, be almost proud of it later, that some functioning kernel of her brain understood screaming would accomplish nothing and might accomplish something worse. She simply turned — not ran, walked, fast, faster, the standing stones rising ahead of her like the mouth of a tunnel back into the ordinary world — and did not look behind her, though the breathing followed, patient, unhurried, matching her pace exactly no matter how quickly she moved, right up until her hand closed on the rough bark of the nearest oak and the whole grove behind her simply — stopped. Sound returned all at once, wind, distant traffic, an owl somewhere off toward Pembroke Lodge, ordinary blessed noise flooding back into her ears like water into a cracked jar. She stood gripping the tree, pendant blazing hot enough to hurt, and did not go back to see whether anything had followed her out.
