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.

She had not intended to come to Richmond Park after dark. Richmond closed at dusk. The gates locked at seven-thirty in February and the rangers actually checked, torches sweeping the roadways for stragglers and teenagers. Rory had to leave her busted push bike chained to the railings on the Petersham side and climb, which was not elegant at five-six in the cheap trainers she wore for Golden Empress deliveries. The metal was cold enough to burn her palms. On the other side, her breath came out in white puffs and the city went suddenly quiet, as if someone had turned a dial down. She told herself it was logical. That was her job, to be cool-headed. To think out-of-the-box, like Eva always said when she was half-taking the piss. The pendant hadn't stopped. She'd found the Heartstone on her narrow bedside table three weeks ago in its little unmarked box, on the silver chain, no note. Roughly the size of her thumbnail, deep crimson, with a faint inner glow that you could only see if you cupped it in your hands and looked properly. She'd assumed Eva, or even Silas being weirdly sentimental about the rent, until the first time she'd walked past the old service door in the basement of the building above the bar and it had pulsed. Not light, exactly. Warmth. A sudden, insistent throb against her sternum, like a second heartbeat. It had been doing it again for the last hour, stronger every minute while she was trying to close up after the dinner rush. Yu-Fei had told her to go home early. And then the warmth had gone cold, then hot again, tugging. Not toward the basement. West. Rory walked now with one hand tucked inside her delivery jacket, fingers closed around the stone. It was hot. Too hot. It wasn't burning the skin, but the heat sat deep, like she'd swallowed something warm and it had gotten stuck behind her ribs. She knew where she was going before she saw the trees change. Everyone who grew up on the edge of Cardiff knew what a park at night should feel like — damp, empty, a little hostile. This wasn't that. Richmond at night was still London. You could always hear the road. The planes. But between a stand of beech trees she hadn't meant to walk between, the road went away. The air went still in a way that had weight. She stopped. The grove opened in front of her, and she knew, with a stupid, delayed clarity, that this was the place. The clearing wasn't marked on any park map she had ever seen tucked up in the delivery office. It was too perfect, a circle pressed into the woods. At its edge stood the oak stones, not boulders but living oak trunks, thick as houses, grown into standing stones, their bark smoothed by age. Inside them, the ground was covered in wildflowers. In February. Rory stared. White and yellow and a pale, bruised purple, all open, all blooming in the frost, their heads tipped up to a sky she could no longer see properly. The clouds above the clearing were not the London skyglow orange. They were deeper, and between them there were too many stars. Her pulse had gone loud in her ears. Her left wrist itched. She rubbed at the small crescent-shaped scar there without thinking, a habit from childhood. Evan had once asked her how she'd gotten it and she'd said a kitchen accident and left it at that. "It's just a microclimate," she said out loud, and her voice sounded wrong. Too small. The sound didn't carry. The pendant pulsed again, hard, and Rory sucked in a breath. In the center of the grove, the air shivered. It was not a door. There was no frame, no light. It was just that if she looked at that spot directly, her eyes slid off it. The space between two clumps of flowers seemed to be both further away and much, much closer than it should be, and the longer she looked, the more she felt the cold coming off it. Not temperature. The opposite of the pendant's heat. The Hel portal, she thought, or a mouth trying to think the word Hel portal. The story her mother used to tell her when she was a kid about the places where the world was thin. She should leave. That was the cool-headed, intelligent thing to do. Take the weird rock a benefactor left and get the hell out of the Fae-touched pocket that she had no business knowing existed and call in sick tomorrow and let someone else deal with ancient ley lines. She took a step backward. Her trainer didn't make a sound on the soft ground. That was when she realized she hadn't made a sound since she'd stepped between the beech trees. No crunch of leaves. No twig snap. The wildflowers were perfectly still. The wind had stopped. Rory turned to look back at the way she had come and the beech trees were not there. Or rather, they were, but there were more of them, pressed close together, their trunks pale in the dark, their branches bare and interlocked overhead into a lattice that blocked the sky. The gap she'd walked through was gone. Her throat went tight. She swallowed once. Twice. "Okay," she whispered. "Okay. Fine. Out-of-the-box thinking. Boxes are... there are no boxes." She reached for her phone. No signal. The clock on the lock screen read 22:47 and then, as she watched, it flickered to 22:46. The pendant throbbed again. When it did, something in the clearing answered. Not a sound, at first. A pressure change, like going down too fast in an elevator. Rory's ears popped. The wildflowers trembled. From somewhere beyond the oak stones, a twig snapped. It was a loud sound in the hush. Deliberate. She whipped her head toward it. Nothing. Just the dark between the trees and the faint outline of the oaks. Her bright blue eyes, usually so good in the low light of restaurant alleys and bar stairwells, caught only edges. Then another snap, on the opposite side of the clearing. Her fingers tightened around the Heartstone until the silver chain cut into the back of her neck. She was not alone. The certainty arrived whole and absolute, not built from evidence but installed, like a new fact about gravity. She was being looked at. From below, from the flowers. From above, from the branches that hadn't been there before. From inside the shiver in the air that her eyes wouldn't resolve. Rory tried to breathe in a four count the way she had after she'd left Evan. Inhale four, hold four, out four. On the second cycle, she heard it. Footsteps. Bare. Soft, wet footfalls in earth that was not wet. They were not in front of her. They were behind the shiver. Or they were the shiver learning how to walk. Each step was slow, considered, and with each one the cold deepened, pushing against the heat of the stone in her hand until her palm sweated and shivered at the same time. Wildflowers moved at the edge of her vision. Not swaying. Flattening, as if something without weight was passing over them, pressing the blooms down in a trail. The trail was coming toward her. Rory backed up. Her shoulder hit something that wasn't a beech tree. It was warm, and it gave slightly, like bark over flesh. She jerked away without looking, a short, sharp noise escaping her that she hated instantly. The pendant pulsed faster now. Panic-hot. It wanted to be noticed by whatever that cold spot was. "No," she said to it, to whatever was listening. "No thanks." She yanked the chain off over her head, the silver catching in her straight black hair. For a second her hands wouldn't work and she was back in her old flat in Cardiff, trying to get a key in a lock with a man shouting on the other side. Then it was free. She held the deep crimson stone out at arm's length, away from her body. The cold stopped approaching. In the center of the clearing, where there had been only a blur, there was now a shape. It was tall. It was still not right. It was like a person but made of the spaces between the trees, sketched in absence. Where its face should be, Rory saw, for a half-second, her own flat above Silas' bar, but wrong, with the windows open onto a night that had too many stars. The pendant was throbbing so fast it was almost vibrating. The faint inner glow inside the crimson was brighter now, casting a red wash over her knuckles, over the little crescent scar gone white. The thing tilted, as if curious about the light. Rory did the only intelligent thing she could think of. She opened her fingers. The Heartstone didn't fall. It hung in the air for a breath, suspended between her palm and the cold. Then it moved — not falling, being taken — in a straight, smooth line toward that hollow in the middle of the grove. It stopped an inch from the blur and simply hung there, spinning slowly on its chain, heat and cold fighting in the air around it until the wildflowers within a foot of it blackened and curled. The footsteps stopped. The shape in the middle of the grove seemed to bend. Not bend over. Bend *toward* the pendant, in a way that made Rory's stomach drop and her vision swim, as if its spine had too many joints. It didn't touch the pendant. After a long, terrible moment where nothing moved, the air shivered again and spat the stone back. It hit the soft earth with a dull thud and the glow inside it winked out, just for a second, like an eye closing. Time snapped back. Sound returned all at once — wind through branches, a distant car horn from beyond the park, a real dog barking somewhere far off, and Rory's own ragged breathing, too loud. Between the beech trees, the gap was open again. She could see the ordinary London dark beyond it, the faint orange sodium sheen on the clouds. She did not pick up the pendant right away. She stared at it, lying in the crushed flowers. Then she scooped it, chain and dirt and all, and shoved it into her jacket pocket where it sat inert and cool against her ribs. She ran. She didn't look back at the oak standing stones as she passed them, but she felt their bark watching her. She hit the real woods, and twigs snapped under her trainers properly this time, loud, honest sounds, and kept running until the fence was in front of her again and she had to climb, scraping her left wrist open right next to the old scar, and sting was such a normal, welcome thing that she almost laughed. On the other side, on the pavement, under a real streetlight, she stopped and put her hands on her knees and tried not to be sick. Her phone buzzed. Signal returned. The clock read 22:48. She had been in there for one minute. In her pocket, the Heartstone was warm again.
