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 at Sheen Cross had been chained since eight, so Rory went over the wall. She'd done worse things in trainers. The drop on the far side was longer than she'd judged, and she landed badly, her ankle turning in the wet grass, and she crouched there in the dark with her palms flat against the ground and waited for someone to shout at her. Nobody shouted. Richmond Park at half past eleven on a Tuesday in November was two and a half thousand acres of nothing, and the nothing swallowed the sound of her landing whole. She straightened up. Her breath came out white and drifted off toward the trees. The pendant lay cold against her breastbone. That was the thing that had brought her here — not warmth, not the low pulse she'd learned to dread, but the opposite. Three days ago the Heartstone had gone cold. Not room-cold. Cold like a coin left out in frost, cold enough that she'd woken at four in the morning with the shape of it burned white against her skin, and she'd sat up in the dark above Silas' bar with the taste of pennies in her mouth and known, with the flat unarguable certainty of a person who has stopped being able to afford disbelief, that something had changed. And when she'd walked west with it, toward Richmond, the cold had gotten worse. Cleaner. Like following the edge of a blade to its point. So. The grove. Because Isolde had told her once, in that voice like water over stones, that if things ever went badly wrong she should come to the grove, and Rory had filed it away with everything else she'd been given instead of an explanation. She went up the slope past the plantation, keeping to the deer paths. The grass was rimed and it crunched, and every crunch sounded enormous. Somewhere off to her left a stag coughed — that hoarse, throaty bark that always sounded like a man clearing his throat in an empty room. Rutting season was over. He should have been quiet. She stopped and listened until the sound didn't come again, and then she kept walking, and told herself that a stag out of season was not a sign of anything. The standing stones came out of the fog before the trees did. There were nine of them, oak, black with age and slick with condensation, each one taller than she was and set in a rough circle around a gap in the world. She had never been able to see the grove from outside. That was the point of it. You saw the stones and you saw, between them, more of the same park — bracken, birch, the orange stain of London on the underside of the clouds. Then you stepped through and there was a clearing full of wildflowers in November, and the air was warm, and time went sideways. She put her hand on the nearest stone. It was wet and rough and utterly ordinary and her fingers came away smelling of nothing at all, and she thought: *that's the first wrong thing.* The stones always smelled. Wet oak, moss, that green cellar smell. She'd never noticed she'd noticed until it was gone. Rory stood there with her hand hovering and made herself count to five. Then she stepped through. The warmth hit her the way it always did, like walking into a kitchen. Wildflowers to her knees — cornflowers, ragged robin, ox-eye daisies, all of it impossible, all of it there. The sky above the grove was its own sky, deeper than the one outside, and it held stars that Rory had long since given up trying to match to anything. Nothing moved. That was the second wrong thing. The grove was never still. There were always things in the flowers, small quick things she never quite saw, and a sound underneath everything like a held note, like a finger circling the rim of a glass. She'd found it unbearable the first time. She'd have given a finger to hear it now. "Isolde," she said. Her voice went out about six feet and stopped. Just stopped, the way a shout stops in deep snow. Rory turned a slow circle. The clearing was maybe forty paces across and she could see all of it, and all of it was empty. The flowers stood up straight and perfect and unmoving in the warm windless air. "Isolde. It's Rory. Aurora Carter." She swallowed. "You told me to come." Behind her, something walked through the flowers. She heard it clearly: three, four soft strides, the swish of stems against a leg, off to her right and close, close enough to touch. She turned toward it with her heart going like a fist on a door, and there was nothing there, and the flowers were not bent. "Right," she said. "Okay." She reached for the pendant and hissed. It had gone from cold to *burning* cold, so cold it hurt to hold, and she let it drop against her shirt and stood there with her scalded fingers curled into her palm and her whole body screaming *out, out, go out.* She looked back at the gap she'd come through. There were nine stones and she could see all nine of them from where she stood, and every one of them showed her the same thing: warm grass, warm flowers, warm night. The park was gone. Not hidden. *Gone*, like a word taken out of a sentence. Rory made herself breathe. In through the nose, four counts, hold, out. It was a thing her mother had taught her for exams and she had used it in worse rooms than this. *Think. What do you know.* She knew the grove sat in a pocket between two places. She knew a pocket had to have a seam. She knew that whatever was in here with her had let her walk in, and that if it wanted her dead she'd have been dead in the first ten seconds, and that therefore it wanted something else, and that things which wanted something else could be bargained with, stalled, lied to. She knew she could hear breathing. It had started so quietly she'd taken it for her own. It wasn't. It was slower than hers, and it had a catch in it, a little wet click at the top of each inhale, and it came from everywhere in the clearing at once, the way sound comes off a wall. "I'm going to ask you a question," Rory said, and was distantly proud of how level she kept it. "And I'd rather you didn't answer it in a voice you've borrowed. That's all. Just — your own, if you've got one." The breathing stopped. For nine or ten seconds the grove was so silent that she could hear the blood in her ears, a soft insistent shushing, and she understood suddenly and completely that it was listening to her the way she listened to it. That it was waiting to see what she was. Then, from the far side of the clearing, in a voice that was warm and slightly amused and unmistakably her mother's: "Rory, love. You're standing in the flowers." Rory did not turn around. She kept her eyes on the stone in front of her, on the black wet grain of the oak, and she thought about the shape of the wall at Sheen Cross, and the drop on the other side, and how far a person could get in the dark if they didn't stop to look back. The flowers behind her began, very softly, to move.
