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 marking the boundary of the Grove looked different at night. Rory had been here twice before, both times in the gray hour after dawn when the standing stones seemed almost friendly, softened by mist and the ordinary business of birds. Now, past midnight, they stood black against a sky that held no moon, and she had the sudden, unwelcome thought that they were not markers at all but teeth, and she was walking into a mouth. She told herself this was stupid. She'd come because the pendant had gone warm against her collarbone around eleven o'clock, warmer than she'd ever felt it, and warmth meant a portal, and a portal near the Grove meant something worth seeing before it closed. That was the whole of her reasoning, formed in the twenty minutes it took to throw on boots and a coat over her pajamas and catch the last stretch of unlocked path into Richmond Park before the gates shut for the night. Practical. Reasonable. The kind of quick thinking Eva always teased her for, the kind that had gotten her out of worse places than a public park after hours. It did not feel reasonable now. She stepped between the stones and the temperature dropped, the way it always did, like walking through a curtain of cold water that left no trace of wet. The wildflowers underfoot glowed faintly blue-white in the dark, the way they always did, blooming out of season because the Grove did not know what season was. Everything was as it should be. That was almost the worst part — nothing had visibly changed, and yet the moment her second boot crossed the threshold, something in her chest tightened like a hand closing slowly around a fistful of wire. She stood still and listened. Nothing. Wind, maybe, somewhere far off, moving through leaves she couldn't see because the canopy here didn't behave like canopy, folding away into a darkness that had no top. The pendant against her sternum pulsed, once, warm as a held coal, and then went quiet. "Right," she said aloud, mostly to hear her own voice do something ordinary. "Right, then." She walked the way she remembered the pull of warmth had been strongest, toward the center of the clearing where the grass thinned to bare earth in a rough circle, like something enormous had once knelt there. The flowers here didn't glow. She noticed that only after she'd already gone ten feet past the last of them, and when she looked back the blue-white light seemed farther away than it should have been, as though the distance between her and the boundary had stretched without her walking it. That was when she heard the first sound that didn't belong. It was a small sound, almost nothing — a soft, wet click, like a tongue against the roof of a mouth, off to her left where the trees thickened into true black. She turned. Nothing. Of course nothing; there was nothing to see in that direction, the dark was total, and she had the distinct and unhelpful realization that if there were something to see, she likely wouldn't want to. "Hello?" Her voice sounded smaller here than it had a moment ago. The Grove ate it, the way it ate distance, the way it ate time. No answer. She hadn't expected one. She started walking again, faster now, angling toward where the pull of the pendant's warmth had felt strongest — she was almost sure it was still that direction, though the dark had rearranged itself somehow while she wasn't looking, the way a room does when you close your eyes too long in it. The click came again. Closer. She stopped breathing for a second, made herself start again, slow, controlled. Deer, she told herself. There were deer in Richmond Park, hundreds of them, and if any of them had followed her scent through the stones — but no. Deer didn't sound like that. Deer didn't sound like a mouth deciding whether or not to open. She kept walking. The bare earth circle came into view ahead, darker than the dark around it, and she told herself that was where the portal would be, that this was the plan, get in, see what's there, get out, the way she'd done a dozen times with a dozen strange doors since London had started swallowing her whole in ways Cardiff never had. Something moved at the very edge of her vision. Not ahead. Not to the left, where the sound had been. Behind her, low, at the height of a crouching man, gone before she'd turned her head far enough to catch it directly — the way a shadow moves when a curtain shifts, except there was no curtain, no window, no reasonable source of moving shadow here at all. Her skin went cold in a way the Grove's chill couldn't account for. She did not run. She was proud, distantly, in some small clear corner of her mind that was still capable of pride, that she did not run. She walked, faster, toward the bare circle, and the pendant at her chest had gone warm again, warmer, warm enough now that she could feel it through her shirt, and she thought: good, that's the door, get to the door. The click came a third time, and this time it did not come from one direction. It came from all of them at once, low and wet and patient, like something enormous breathing through a throat too small for the sound, and underneath it, so faint she almost mistook it for her own pulse in her ears, she heard breathing that was not hers. She stopped at the edge of the bare circle. There was nothing there. No shimmer, no seam of light, no portal at all — only packed dirt, pale as bone under a sky with no moon to explain the paleness. Behind her, close enough now that she felt it disturb the air at the back of her neck, something exhaled. Rory did not turn around. She had learned, once, a long time ago, in a different kind of danger, that turning around to look a thing in the face was sometimes the very worst thing you could do, that some things wanted to be looked at, hungered for it, and that the only weapon left to her in that first frozen second was to deny it that. She fixed her eyes on the dark tree line ahead, made her legs move, one step, then another, walking without running toward the boundary stones she could no longer see, and behind her the breathing kept its pace with hers, patient, unhurried, in no rush at all to close the distance between them — because it didn't need to be.
