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.

Richmond Park after dark was supposed to be closed. The gates were locked, the rangers gone home, and Rory had to lift her old delivery bike over the low fence near Roehampton, swearing under her breath when the chain snagged her jeans. She hadn't come for a shortcut. The text from Eva had been short. *He was here. The grove. Come at eleven. Don't be late.* No context, no follow-up, and when Rory called, it went straight to voicemail. Eva never went to Richmond after sunset if she could help it. Eva thought parks at night were where bad things happened to women who made bad choices. That was exactly the kind of thing Eva would say. So Rory came. The park was too quiet. That was the first wrong thing. London never stopped making noise, even in its green spaces - distant traffic on the A3, planes stacked for Heathrow, foxes screaming at each other like murdered children. Tonight the air had been vacuumed out. Her trainers on the dirt path made no real sound. The wind didn't move the bracken. Her breath plumed and vanished too fast. She reached the oaks. She knew them even in the dark, the ancient standing stones that weren't stones at all but the trunks of oaks grown so thick and gnarled they had swallowed their own hearts. They made a loose circle in a dip in the land where the map said there shouldn't be a dip at all. Inside that circle, the grass was always wrong - too green for November, and wildflowers blooming year-round in a dense, messy carpet, white stitchwort and yellow tormentil that should have been dead weeks ago. Rory stopped at the boundary and put a hand on one of the oaks. The bark was damp and cold. Around her neck, the Heartstone pendant shifted. It was small, roughly the size of a thumbnail, a deep crimson stone on a silver chain that she had not taken off since it appeared in her jacket pocket last winter with no note attached. Normally it hung inert. Now it was warm. It pulsed. Not light, not really, just a faint inner glow like an ember breathing, and a wash of heat against her sternum that faded and came again, stronger. She frowned down at it. In the past the heat had only meant one thing. A door. A Hel portal, thinning somewhere close enough to feel. The old stories Silas told over the bar downstairs after last call - he always said Hel didn't like to open near the Grove because the Grove didn't belong entirely to Earth. "Rory?" Her head snapped up. Her own voice, hoarse, came back too loud in the quiet. "Eva?" Nothing. She pushed between two of the oaks. Past the boundary, the air changed. It always did, that subtle pressure shift like stepping into an elevator, but tonight it was sharper, a drop in altitude in her ears. The clearing beyond was larger than it should have been, the trees leaning away to make a sky that held more stars than Richmond ever saw. The wildflowers were open at midnight, their heads turned up. And time slipped. She felt it go sideways, the way the Grove did when it wanted to. The pendant in her university halls in Cardiff had never felt like this. An hour inside could be minutes or days outside and she had learned not to wear a watch in here because it made her sick to watch it spin. Tonight the flowers were too still, too. Like they were listening. Her bright blue eyes were slow to adjust. Her black hair, cut straight to her shoulders, kept catching on the collar of her delivery jacket from Golden Empress - she hadn't changed after shift. She shoved it behind her ears with a hand that was shaking just slightly. "Cool-headed," she muttered, trying to borrow Jennifer Carter's teacher voice, her mother's voice telling a panicked student to breathe. It was what everyone said about her. Rory was the cool-headed one, the one with quick, out-of-the-box thinking. She wished she felt it now. The pendant pulsed again, hotter. The crimson deepened until she could see it through her t-shirt. Warmth near a portal. That was what it did. A sound came from the far side of the clearing. Not a twig snap - a wet sound, like a foot coming out of mud, though the ground was dry. Rory's spine went straight. She wasn't alone. She turned her whole body toward the sound, not just her head, the way Brendan had taught her when she was a kid and he thought she should take self-defense despite wanting to be a barrister like him. Face the threat. Don't give them your back. There was nothing there. Just more flowers and the dark shape of the oaks. Then, at the edge of her vision, something moved. Not walking. It didn't walk. It was between the oaks for half a second, tall enough that its head would have brushed the lower branches, and then it wasn't. Her eyes skipped over the spot like water over oil. "Okay," she said, and her voice was too small. "Okay, funny." The quiet after was worse than the sound. It had weight. It pressed on the inside of her ears until she had to pop them by yawning. Her left wrist itched where the small crescent-shaped scar pulled tight - old white tissue from when she was seven and fell on a broken mug in her mother's classroom. She rubbed it without thinking, a nervous habit. She should leave. That was the intelligent thing. The cool-headed thing. Get out, bike home to the flat above Silas's bar, hammer on Eva's door until she woke up and explained why she sent Rory to a fae-touched pocket in the middle of the night. The pendant throbbed against her skin, a third heartbeat. And from the center of the clearing, where there should have been nothing but flowers, came a soft exhale. Rory froze. It was not wind. It was a breath taken and let out through teeth that were too close together. The flowers in the very middle were bent. Not trampled. Bent outward in a perfect circle, as if something heavy had been lying there a long time and only just gotten up. She looked up. The standing stones were wrong. She counted. There had always been seven oaks marking the boundary. Always seven, a number the old stories liked. She counted again, her lips moving. Eight. The eighth was new. Or - no. The bark was just as thick, just as black with age. The gap it stood in had always been there, a narrow slot between two other trunks she had to turn sideways to get through. She remembered ducking through it. Now it was filled with solid wood that hadn't been there minutes ago. The air went colder. A second footstep, wet and slow, from behind her. Rory didn't turn. Every nerve in her finished now, every hair rising under her jacket. The certainty came all at once, not building but arriving whole: something was directly behind her, close enough that she could feel the heat differential, the absence of cold where it stood. It was not breathing. It was waiting for her to look. She stared straight ahead at the bent flowers, at the clearing that was somehow deeper than it had been, the trees further away. Her hand found the pendant. The silver chain bit into her fingers. The stone was almost hot, its faint inner glow now bright enough to throw a red stain up onto her throat. The wrongness wasn't that she was not alone. The wrongness was that the Grove had let her in anyway, knowing what was already inside. A third sound, from directly behind her left ear, so close her straight black hair stirred though there was no wind - a thin, curious inhale, as if something tall were bending down to smell her scalp. Rory's fingers, white-knuckled, shoved the pendant down into her shirt, against the bare skin over her heart. She didn't run. Running would make it chase. She stepped forward, one foot into the bent circle of flowers, toward the center that was not a center anymore, because the intelligent, out-of-the-box thing was not going back the way she came. The way she came was blocked. Behind her, something shifted its weight and settled, patient, and the Groves's strange time stretched thin as a membrane. She took another step deeper in.
