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 to Richmond Park was locked. Rory stood with her hands in the pockets of her delivery jacket and stared at the chain. It was after one in the morning and the rain had stopped an hour ago, leaving the tarmac on Sawyer's Hill slick and black and reflecting the sodium orange of the streetlamps. The park closed at dusk in winter. She knew that. Everyone knew that. The chain was new, or she had never noticed it before, heavy links and a council padlock the size of her fist. The text from Eva was still lit on her phone: *didn't want to freak u out but im at the grove. can't leave. pls come, don't tell Silas*. Sent three hours ago. No read receipts since. She had told Silas anyway. He'd been wiping down the bar below her flat, had looked at the message, and had said, "Rory, love, that place at night?" And then he had gone quiet when she pulled out the keys to her old bike. It was stupid to come. Cool-headed was what people called her when they wanted to say detached. Eva called her relentless. Her mother would have called her contrary, in that teacher voice before she went back to her marking. All of them were probably right. She was twenty-five, five-six in her trainers, working lunch shifts for Yu-Fei Cheung and sleeping above a pub that smelled faintly of bleach and old hops, and she still had not learned how to leave a message unread. She left the bike against the gate and climbed. The park at night was not the park she cut through on deliveries. Without people, without dogs and joggers and kids, it was too large. The oaks were too far apart and too still. The wet grass swallowed sound. Her breath made faint clouds. Above her, the sky was low and clouded, no stars. The grove was not on any map of Richmond Park, not the tourist one they gave out at the kiosk or the Ordinance Survey one on her phone that she used for drops. Isolde had shown it to her once last summer, when the heat had put everyone in a strange mood. Isolde's grove, she'd called it. A pocket. You had to know how to look. Rory found the path anyway, or the path found her. The trees funneled. Her boots, old Docs with the sole coming loose on the left one, found mud where there should have been gravel. And then the standing stones. They were not supposed to be here either. Four of them, ancient oaks that had grown into pillars, or stones that had learned to be trees. Their bark was black with rain. Each was twice as tall as she was, leaning slightly inward, a rough circle around a clearing that should have been too small to hold them. She had forgotten how big they were. The air changed when she stepped between them. It was warmer. Noticeably. The smell of wet earth and leaf rot cut out all at once and was replaced by something green and too alive. And the light changed, although there was no source for light. The clearing was leading her eyes wrong. The wildflowers were in bloom. That was the first wrong thing, truly wrong, that made her hand go to the silver chain at her throat. In January. In the dead middle of a London winter after a week of frost warnings, the grove floor was covered in them. Small white stars and yellow buttercups and something purple she didn't know the name of. Year-round, Isolde had said. It hadn't seemed literal at the time. Rory's thumb found the pendant. It was roughly the size of her thumbnail, deep crimson, set in a plain silver bezel that had gone dull from wearing it every day for six months. The unknown benefactor. That was how she still thought of it, even now, because no note had come with the padded envelope slipped under her flat door and no one had claimed it. The stone was supposed to be glass, probably, some Etsy thing. Only now it was not cold. It was warm. Not from her skin. A slow, deliberate pulse against her sternum, like a second heartbeat slightly out of time with her own. When she lifted it, there was a faint inner glow to it, pulsing. Faint, then stronger. She let it fall. The pulse stayed. "Eva?" she called. Her voice did not carry the way a voice should in an open space. It stopped two feet out, muffled, as if the clearing had packed cotton around it. The second wrong thing was the quiet. Richmond Park was never quiet. Even at night you heard the North Circular, you heard planes coming into Heathrow, you heard foxes screaming. Here there was nothing. No wind in the high branches. No distant traffic. Then, underneath the nothing, a sound that wasn't a sound at all, more like the feeling of sound heard through a wall. Rory's hand went to her left wrist without thinking. The small crescent-shaped scar there, pale against the inside of her forearm, always itched when she was nervous. Childhood accident, her father's razor left on the side of the sink when she was eight, her father still telling the story as proof she had always been too curious for her own good. She had come here for a reason. Say it plainly. Eva was in trouble. Eva had sent her a location that barely existed and told her not to tell anyone. And now Eva was not here. The flowers were wrong. The light was wrong. The pendant was warm and getting warmer. She turned a slow circle. Her straight black hair, cut to her shoulders, had come loose from behind her ears. Her eyes, bright blue even in dim light, kept catching movement at the edge that wasn't there when she looked straight on. There, between the second and third stones. A flicker. Not an animal. Too tall. She snapped her head toward it. Nothing. Only bark and the impossible flowers. Then, from the opposite side of the clearing, a soft footfall. Not in the mud. Above the mud. A compression of air. Rory's mind, cool-headed to a fault, started listing. List what you know. List what you can prove. It was a trick her father, the barrister, had taught her for exams and which had stuck through Pre-Law at Cardiff and through leaving Cardiff and through leaving Evan. One: The grove was a pocket between Earth and the Fae realm. Isolde had said that, and Isolde lied as easily as she breathed, but she had shown Rory how time slipped there. Her phone now read 1:17, then 1:16, then 1:19. Two: The pendant pulsed when near a Hel portal. That was not from Isolde. That was from the little folded paper that had come with the pendant, in handwriting she didn't know. She had thought it was nonsense. A LARP thing. She had kept it anyway. Three: She was alone. The thought came with a little click, like a door locking from the inside. She was not alone. The certainty arrived complete, without process. The back of her neck prickled. The fine hairs on her arms rose under her jacket. Somewhere behind her, just behind the veil of her vision, something stood where Eva should have been standing and was looking at her with attention. The wildflowers shivered. There was no wind. "Rory?" Eva's voice. Very faint. Coming from the trees. "Rory, don't—" It cut off. Rory's head jerked up. "Eva?" Nothing. Or rather, a mimic of nothing. The quiet pressed in closer. The pulse of the Heartstone against her skin quickened. The faint inner glow was no longer faint. It bled through her thin t-shirt, a deep crimson light that painted the white flowers red. She took a step back and her boot found no purchase. The ground had softened. Not mud. Something else. The flowers were taller than they had been. Inches taller, in the space between blinks. She could see them growing, she was sure of it now, slow and terrible, stems elongating with a sound like knuckles cracking. At the edge of the clearing, between the ancient oak standing stones, the dark was thicker. Not shadow. Thickness. As if the air had been folded over too many times and had started to stick. It pulsed, too, in counterpoint to the pendant. Warm. Then cold. Warm. Something moved in the thickness. Not at the edge of vision now. Directly. A long shape uncurling itself from a shape that had pretended to be a tree root. An outline that learned itself into being the longer she looked. Too many joints. Her breath caught. Her quick, out-of-the-box thinking, the thing that had got her out of her viva when she blanked and out of Evan's flat with a duffel and a split lip, went white and empty. She thought: an hour inside can be minutes or days outside. She thought: If I run, which way is out? The standing stones were still there, four of them, but she could no longer remember which gap she had entered through. All four gaps looked identical, all four filled with that thick dark. And the flowers had risen to her ankles, to her shins, soft and cold and gripping. The footfall came again, closer. A careful, curious weight being placed on the other side of the pocket. And in the center of the clearing, where the flowers were thickest, the air finally tore, just a finger's width, just enough to let through a spill of lightless air that made the pendant flare hot as a coal against her skin. From beyond the tear, something exhaled, and it knew her name.
