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 air in Richmond Park after midnight had a different weight to it. Rory stood at the edge of the path where the tarmac gave way to mud and thought that she shouldn't have come. The streetlamps behind her threw her shadow long and thin across the grass, shoulder-length black hair cut sharp against her neck. She pulled her jacket tighter. It was late October and cold enough that her breath fogged, but ahead, past the line of trees she knew marked Isolde's grove, the air looked wrong. Softer. She checked her phone again. No signal. 00:47. A single text from Eva, sent at 21:12. *need you to check the grove, left my bag there this afternoon. pls Rory. can't go back tonight.* The text was wrong too. Eva didn't type like that. No lowercase, no emojis. And Eva never called it the grove. But the bag could be there. Eva had been jumpy all week, talking about lights between the oaks. Rory had told her she was imagining things and now she felt the cheap guilt of it, the kind that made you get on a night bus. So she'd come. Park gates closed at dusk, but she knew the gap in the fence by the nursery. She'd walked twenty minutes in darkness with the city humming faintly on every side and getting fainter, until it wasn't. She stepped off the path. The ancient oaks that marked the boundary were older than any trees had any right to be this close to London. They weren't arranged like trees. They were stood like stones, trunks wide and gnarled, spaced too evenly, bark black with damp. The Heartstone pendant at her throat shifted as she moved, the silver chain cold against her skin. The stone itself, no bigger than her thumbnail, had been dead weight all week. Now it wasn't. She stopped between the two largest oaks. Past them, wildflowers bloomed. That was the first thing that truly snagged. Not just that they bloomed at the end of October, at nearly one in the morning, but that they were open. White stitchwort and pale bluebells and buttercups she could see too clearly despite the lack of moon. Year-round, she knew. She'd been told that, the way you were told a local legend and half-believed it. Seeing it was different. The white flowers were too white. They didn't tremble in the wind because there was no wind past the stones. Rory touched the small crescent-shaped scar on her left wrist without thinking, thumb pressing into the ridge. A habit when she was trying to think straight. "Stupid," she whispered, and her voice went flat too fast, as if the clearing ate sound. There was no bag. The clearing was maybe thirty feet across, a perfect pocket cut between the oaks. The grass was too even. The air smelled green and rotten at the same time, like a vase of flowers left a day too long. Her delivery job had taught her to notice smells that didn't match their places, kitchens that smelled like bleach over blood, hallways that smelled like gas. This was like that. Something underneath. She took another step and the pendant pulsed. It was faint, a flush of heat against her sternum, then gone. Rory froze. She'd owned it for three months, since it had arrived in a padded envelope with no note, only her name in handwriting she didn't recognize. She'd worn it because it was pretty, because the deep crimson stone went with everything and because Yu-Fei at the restaurant had said it suited her. It had never been warm before. It pulsed again. Slower this time. Warmth spreading out from the center of her chest in a way that was almost comforting, except that her own heart sped up to match it and that felt less comforting. The faint inner glow she had always taken for a trick of the light was visible now, even through her t-shirt, a dull ember under the fabric. She should leave. The cool-headed part of her, the part that had gotten her out of Cardiff and into a flat above Silas' bar and away from Evan, was listing facts very clearly. *No bag. Phone dead. Place known to mess with time. Faint heat from unknown artifact equals walk away, Rory.* She turned. The oaks behind her were closer than they had been. She was sure of it. She'd stepped between them, and there should have been a gap wide enough for a car. Now the two trunks were near enough that she would have to turn sideways to slip out. The bark seemed to have shifted, leaning in. She stared at it and told herself she was bad at distances in the dark. Bright blue eyes wide, she looked longer than she wanted to. The bark wasn't bark up close. It had too many lines, too many whorls that looped and rejoined like writing. The pendant pulsed harder. Heat now, insistent. Rory stepped back involuntarily, away from the shrinking entrance, deeper into the flowers. They brushed her ankles. They were warm too. Then the sound started. It wasn't loud. It was behind the other sounds, behind the pulse in her ears. A faint, shuffling drag, like someone pulling a heavy coat through long grass. It came from the left. She snapped her head that way. Nothing. Just flowers and oaks and a darkness between two trunks that was deeper than the rest. She held her breath. The dragging stopped. It started again on her right. Closer. Rory's hand went to the pendant, fingers closing around it. The crimson stone was hot now, not burning, but too hot to be stone. It beat against her palm like a second heart, out of sync with her own, and for a second she could have sworn the light inside it brightened when the dragging sound moved. Near a Hel portal, it pulsed with warmth when near a Hel portal. She didn't know what that meant. She'd read that once in a book Silas kept behind the bar, when she was bored on a slow night. Hel. Not hell. Hel. A place the Fae didn't speak about. Something moved at the edge of her vision. Not between the trees. Inside them. She kept her eyes forward and saw it anyway, because you always do. A ripple low to the ground, a dent in the flowers where no foot had stepped, moving in a straight line from one oak to another. The buttercups didn't bend back after. They stayed flat. Rory let go of the pendant. She wiped her palm on her jeans. Sweat. She was sweating despite the cold. "Okay," she said out loud, because saying okay sometimes made things okay. "Okay, funny joke, Eva. Or whoever. You got me. I'm leaving." Her voice didn't travel. It fell a foot from her mouth. The idea that time moved differently here came back to her with a new, practical horror. An hour inside could be minutes or days outside. If she screamed, how long would it take anyone to hear her? If she ran, would she come out tomorrow? The dragging sound was behind her now. She did not turn around. Every instinct she had said not to turn around. She had learned that kind of instinct the hard way. If you turn, you see it. If you see it, it knows you see it. Instead she looked down. Her shadow was wrong. There was only one of her, under a sky with no moon, but the flowers cast two shadows. Or rather, the light from the pendant cast one set crisp and red-tinged, and something else cast another, from above and behind her, long and thin and reaching past the stones. It had antlers. Or branches. Or fingers. The pendant pulsed again and the shadow twitched. Rory moved. She didn't run for the gap between the oaks. That was the trap door. She ran for the center of the grove, where the flowers were densest, where a flat stone she had never noticed before sat almost flush with the ground, black and slick. As her foot hit it, the warmth from the pendant flared so hot it hurt, and the air ripped. It wasn't a sound. It was pressure. Like when the tube went past too close in a tunnel, that split second where your ears couldn't pop fast enough. The wildflowers all snapped shut at once. For an instant she saw it. Not the thing behind her, but where it wanted to go. The stone at her feet wasn't a stone. It was a rim. The crimson light of her pendant lit an edge going down, down, a throat of smooth, wet dark that breathed. A portal. The heat wasn't a warning. It was recognition. The dragging stopped right at her shoulder. A cold spot brushed the straight edge of her black hair. It lifted a strand. Rory was cool-headed because she had to be. She had always been the one who thought sideways when the normal plan failed. So she did not pull away from the cold. She crouched and slammed the hot pendant against the black rim with all her weight, skin hissing where silver met something that wasn't stone. The grove screamed without a mouth. The pressure inverted. The oaks jerked back, suddenly far apart again. The dragging thing lost its hold, or lost interest, as the light in the pendant guttered and went dull and cold all at once. Rory fell backward into the buttercups. They were just flowers now, damp and ordinary, closed for the night. The air smelled like London again — wet earth, distant exhaust, a fox somewhere. Her gasp was too loud in the sudden quiet. Her palm was red. The small crescent scar on her left wrist stood bone-white against it. The pendant was dead weight again, crimson dark. Behind her, the gap between the oaks was empty. The shadows were her own. She scrambled up and didn't look at the center of the clearing again. She pushed through the standing stones and kept pushing until the trees were just trees and the path was tarmac under her trainers and the streetlamps were in sight, too orange and too far away, but there. She didn't stop walking until she was at the bus stop with its flickering light. Her phone found signal at 00:48. One minute had passed.
