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.

Rory ducked under the low branch at the edge of Richmond Park and checked her phone again. No signal. The screen showed 11:47 and then, as she watched, it flickered to 11:43. She locked it and shoved it into the pocket of her jacket. She hadn't meant to come this deep after dark. The message had been slipped under the door of the flat above Silas' bar, no envelope, just a folded sheet of cheap printer paper with coordinates and a single line: *Bring it to the grove. Midnight.* No name. The handwriting wasn't Eva's, wasn't Yu-Fei's. She should have thrown it away. Instead she'd pulled the silver chain over her head, felt the familiar weight of the Heartstone against her sternum, thumbnail-sized and deep crimson even in the dim light of her kitchen, and told herself she was just going to look. Just to confirm it was a prank. The air changed three steps past the tree line. London's damp November cold fell away. It was warmer here, and it smelled wrong, like high summer after rain, like cut grass and honeysuckle. Wildflowers bloomed year-round in the clearing, that was what the old stories said, and they did. Even by moonlight she could see them, white and yellow heads open wide in the dark, nodding along the narrow path where there shouldn't have been any flowers at all. Rory stopped at the boundary. The ancient oaks stood in a rough circle, their bark black and seamed, roots knotted deep into the earth like fingers. Standing stones, half-swallowed by the trees, marked the edge of the Grove. She remembered coming here once in daylight with Eva, laughing at how out of place they looked so close to the city, how quiet it got inside. That quiet was here now but it was different at night. It wasn't peaceful. It was complete. She touched the Heartstone without thinking. The faint inner glow pulsed against her skin through her shirt, not bright enough to see, just warm. She had never seen it do that before except once, months ago, when she'd taken a wrong turn near the old service tunnels by the Thames and felt it throb like a second heartbeat. Someone had told her what it meant, that it pulsed with warmth when near a Hel portal, though no one had told her who had given it to her in the first place. The benefactor's note had only said *keep it safe*. It was pulsing now. Slowly. Warm, then cool, then warm again. Rory told herself to turn around. Her bright blue eyes scanned the clearing ahead, the perfect circle of grass inside the oaks, the flowers. Nothing moved. The moon was high and thin, cutting straight down through a gap in the canopy that shouldn't have been there, because Richmond Park had no canopy this thick. This pocket between, she'd heard it called. Between Earth and somewhere else. She listened and heard nothing at all, which was the problem. No traffic from the road she had just left. No planes. No distant sirens. Even the wind had stopped at the stones. She stepped through. The warmth increased immediately. Not the air, the pendant. It beat against her chest, steady and insistent. Her straight black hair brushed her shoulders as she turned her head quickly, certain she'd heard something behind her. Nothing. Only the dark trunks of the oaks. She took another step onto the soft ground and felt the bizarre give of it, like moss that had never been walked on. "Hello?" Her voice was small and it didn't carry. It fell flat, as if the clearing had absorbed it. She shouldn't have called out. The moment she did, she knew it. The quiet that followed was too attentive. Rory pushed her sleeves up, restless, and saw the small crescent-shaped scar on her left wrist catch the moonlight, pale against her skin. Childhood accident, falling on the low wall behind her mother's school in Cardiff. She rubbed it with her thumb, a habit when she was thinking too fast. Cool-headed, Eva always called her, quick with a workaround. Right now quick thinking told her to leave. She didn't. Instead she walked toward the center, because that was where the coordinates pointed. Her trainers made no sound on the grass. The wildflowers brushed her ankles. As she moved, she realized she could hear something after all. Not behind her. Under. A faint, uneven dripping, like water falling onto stone from a great height. Plink. Plink... plink. There was no water here. There had been no rain in weeks. She stopped and listened and the dripping stopped too, half a beat after she did. She started again and it started again, slightly out of sync with her steps. Rory's mouth went dry. She pressed her palm flat over the Heartstone to steady it, to steady herself, and felt its heat spike. It was almost hot now. The silver chain was warm against the back of her neck. The faint crimson light bled just enough through her shirt that she could see it if she looked down, a dull glow pulsing in time with the dripping. At the edge of her vision something moved. She snapped her head to the left. Nothing but oaks and flowers. When she looked straight ahead again, she was sure a patch of flowers ten feet ahead had been disturbed, stems bent as if something had just brushed past them. The air still hadn't moved. Time moves differently inside, she remembered. An hour inside can be minutes or days outside. She checked her phone again without wanting to. 11:47. The same time as when she'd looked before. Or maybe before before. The numbers had reset. The dripping got louder. Or closer. It was hard to tell because it seemed to come from below and from all around at once, and now there was another sound underneath it, very soft, like bare feet shifting on wet stone. Rory went still and held her breath until her ears rang, and for a long second there was only the pendant's heat and the too-sweet smell of the flowers. Then a footstep, distinct, on the other side of the clearing. Rory spun. The standing stones were empty. The trees were empty. The grass was empty. But the sense that she was not alone sharpened all at once from a vague unease into a certainty that made the hair on her arms rise. Someone was standing just out of sight, just behind the trunks, watching. She could feel the weight of attention on the back of her neck, deliberate and patient. She thought of turning and running back through the boundary, but the oaks looked farther away now than they had a minute ago. The circle had widened, or she had come deeper than she thought. The night beyond the stones was no longer the lit orange of London, but a flat, depthless black. The Heartstone pulsed hard enough that it hurt, a flare of heat that made her gasp. In that flare she heard it clearly: a second breath in the clearing, not hers, slow and wet, as if something were breathing through water. It was close. Just off to her right, where the flowers were thickest. Rory didn't look directly. She had learned as a kid, dealing with her father's courtroom stories and later with Evan, that sometimes you see more when you don't stare. At the very edge of her vision, low to the ground, the wildflowers shivered. Not swayed. Shivered, as if something invisible were moving through them on its belly, circling. The dripping kept time with it. Plink. Plink. Plink. And now, between drips, a faint scraping, like fingertips dragging lightly over bark. She swallowed and forced her voice out. "Who's there?" The breathing stopped. The pendant went cold so fast it felt like ice against her skin. The glow snuffed out. For a beat the clearing was utterly still, the flowers frozen, the air held. Then, from directly behind her, a voice answered, too close, barely louder than a whisper, and not in any accent she recognized. "You brought it." Rory didn't turn around. She couldn't. Every quick, out-of-the-box thought she'd ever prided herself on had narrowed to a single, white line: if she moved, it would touch her. The crescent scar on her wrist throbbed inexplicably, a phantom sting from thirty years ago. The cold of the Heartstone spread up her chest and into her throat. In the grass around her feet, the wildflowers, which should not have been blooming in November, which should not have been open at night at all, all turned very slowly, in unison, to face her. And just beyond the circle of ancient oaks, where the black had been, she could now see a thin vertical seam of deeper red light, the exact deep crimson of the stone at her neck, opening like a slit in the air where no door should be, pulsing faintly, waiting.
