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 night air in Richmond Park hung thick and still, heavy with the scent of damp earth and something sweeter that didn't belong to November. Rory Carter pulled her jacket tighter around her shoulders and kept walking, boots sinking softly into the leaf litter. The Heartstone Pendant rested against her collarbone beneath her jumper, a small weight she had grown used to, though tonight it felt warmer than usual. She had come because of the dreams again. Three nights in a row the same image: standing stones like old bones, a clearing that breathed, and a voice that sounded almost like her own whispering her name from somewhere just beyond the trees. She needed answers. The pendant had been left for her by someone who knew more than they should. If this place held any of them, she would find them. She found the boundary where the ordinary park gave way to something else. The oak standing stones rose from the ground like the spines of a buried creature, their surfaces mottled with moss that gleamed faintly under the thin moonlight. Beyond them the world grew quieter, the distant traffic fading as if someone had turned down a volume dial. Wildflowers carpeted the ground in defiance of the season, pale blues and yellows open as though it were high summer. Rory stepped between two of the stones and felt the air change, a soft pressure against her eardrums, the way a plane's cabin sometimes equalised. Inside the grove the moonlight fell differently. It seemed thicker, almost liquid, pooling in the hollows and sliding off the bark of trees that looked older than any she had seen in London. She stopped in the centre of the clearing and waited, listening. Nothing moved. The pendant warmed further against her skin, a slow pulse like a second heartbeat. She lifted it free and watched the deep crimson stone catch the light. A faint inner glow stirred at its core. Near a Hel portal the guide had said, or the packet that had come with it. She still did not know what that meant. Something rustled to her left. Rory turned. The wildflowers stood perfectly still. No wind. She waited, counting her own breaths. Another sound came, softer this time, from behind her right shoulder. The scrape of something dry against bark. She turned again. Empty trees, black trunks against the blue-black sky. The moon had drifted. Or had she been standing here longer than she thought? Time moved differently here. She remembered reading that once, or hearing it, though she could no longer place the source. An hour inside could be minutes outside, or days. The uncertainty sat in her stomach like cold iron. She walked the perimeter slowly, keeping the stones in view. Her shadow stretched long and distorted across the flowers. At the far edge of the clearing a second shadow seemed to linger a moment after she moved on, then caught up. She told herself it was a trick of the light. She told herself that several more times as she completed the circle and returned to the centre. The pendant's warmth had become distinct heat. She could feel it through her jumper now. A thin sound drifted through the trees. It might have been a child's voice, high and distant, singing a song without words or melody. Rory went still. The parks closed after dark; no one should be here. The singing continued for a few seconds, then stopped as cleanly as if a door had shut. Silence rushed back, denser than before. She realised she had been holding her breath and forced herself to exhale. "Hello?" Her voice sounded small even to her own ears. The stones seemed to swallow the word. No answer came. She turned in a slow circle, scanning the tree line. Something pale shifted between two trunks and was gone before her eyes could settle on it. Her pulse quickened, cool-headed reasoning trying to catalogue possibilities: deer, fox, another person come to gawk at the stories. None of them sat right. The wrongness had settled into the air itself, a pressure behind the eyes, a faint metallic taste on the tongue. She decided to leave. The decision felt clean and sensible. She had come, she had seen the place, the pendant glowed; that was enough for one night. Rory started back toward the standing stones she had entered by. After twenty paces she stopped. The stones were no longer ahead of her. She had turned, she was certain of it, yet the gap between the oaks now lay to her left. She corrected course. The flowers tangled around her ankles more thickly than before, stems brushing her calves with a soft insistence. Another sound: soft footfalls on grass, matching her own for three steps, then stopping when she stopped. Rory spun. Empty clearing. The moonlight had brightened, or her eyes had adjusted, picking out details she hadn't noticed earlier. The flowers nearest the centre grew in a perfect spiral pattern that converged on the spot where she had first stood. She hadn't noticed that. She didn't think it had been like that. The singing began again, closer now. No words, just a thin rising and falling that made the hair along her arms lift. She tracked the direction and saw nothing. The pendant burned hot enough that she hissed and lifted it away from her skin. The crimson light pulsed in time with the song, one slow throb after another. She whispered, "What do you want?" and hated how thin her voice had become. Something moved at the edge of her vision, low to the ground this time, a darker blot against the pale flowers. When she turned her head the blot became shadow only, cast by nothing she could see. A second blot drifted near a tree trunk, then a third. They did not approach. They simply existed, patient, watching. Rory backed away from the centre of the spiral. Her heel caught on something and she stumbled, catching herself hard on one knee. Looking down she saw no root, no stone. The ground itself had dipped, forming a shallow depression that mirrored the spiral above. She rose carefully and moved toward the nearest standing stone. The air grew colder with every step. Her breath fogged despite the mild night. The footfalls returned, no longer matching hers. They came from multiple directions now, circling, never quite reaching her. A dry laugh, or something like a laugh, scraped out of the darkness between the trees. It sounded almost human and then not at all. Rory reached the stones and found the gap. Relief rose and died in the same breath. Through the gap she could see Richmond Park lingering under ordinary streetlamps and ordinary dark. But the park looked farther away than it should have, as if viewed through water. When she put her hand out, her fingers met a soft resistance that gave slightly, like wet silk. She pushed harder. The resistance held. The singing rose behind her, no longer distant, several voices now overlapping, some high, some low, none of them using language she recognised. She turned her back to the gap. The clearing was no longer empty. Dark shapes stood among the flowers at varying distances, too tall to be animals, too still to be people. None of them stepped forward. They simply waited. The pendant's glow cast a thin red wash across the nearest flowers, making them look wet, or open, like little mouths. Rory forced her breathing into a steady rhythm. She was cool-headed. She was intelligent. Panic would only narrow her choices. She needed to think. The spiral pattern in the flowers shifted. Slowly, almost politely, the blooms turned their faces toward her as if they possessed necks. A soft tearing sound accompanied the movement. She took one step sideways. The shapes adjusted with her, maintaining their arcs. The air carried a new smell under the wildflower sweetness: old leather, rain on iron, something faintly sweet and spoiled. The Heartstone pulsed faster. Warmth radiated up her throat into her jaw. One of the shapes lifted what might have been a hand. Or a branch. Or neither. Rory did not wait to see. She spun and shoved both palms against the silken resistance of the boundary with all her strength. For a moment it stretched, thinning under her weight. Through the membrane she heard ordinary night sounds, a far car horn, a dog barking twice. Then the membrane pushed back and she stumbled inward again, heels skidding on flowers that had grown more dense by the second. The singing stopped as if cut with a knife. In the sudden silence she heard her own heart and something else: a wet inhalation drawn by many mouths at once. The shapes began to close the distance, still patient, still quiet, the flowers parting under feet she could not quite see. Rory's scar on her left wrist prickled as if newly cut. She wrapped her fingers around the pendant and felt its heat sink into her hand like a brand. The crimson light strengthened until it threw sharp shadows that bent the wrong way. They were almost level with her now. No faces. Only the suggestion of height and the absolute certainty that if she tried to name what they were the knowledge would roll over her and leave her hollow. She backed until her shoulders met the standing stone. Cold moss pressed through her jacket. The first shape raised its hand again, closer this time. Pale, long, jointed more times than it should be. Rory did not scream. The sound stayed locked behind her teeth. She lifted the pendant higher instead, letting its light flare between them. The nearest shape hesitated. The others paused with it. For the space of three of her racing heartbeats nothing moved. Then the flowers at her feet began to climb, soft stems curling around her boots, gentle and relentless, tasting the leather, tasting her. The moon slipped behind a cloud that had not been there a moment earlier. Red light from the Heartstone became the only illumination left in the Fae Grove. In that light the shapes showed edges she wished she could unsee. The boundary behind her gave another soft, wet sigh, no longer resisting but inviting her in the wrong direction, deeper into the pocket where Earth and Fae brushed against each other like teeth. She understood, with a clarity that tasted like blood, that leaving was no longer the first problem. Surviving the next few minutes was. The stems tightened around her ankles. A second voice joined the first inside her head, not singing this time, speaking her name the way someone might taste a new word for the first time. Rory Carter. Aurora. Laila. Malphora. All the names she had ever worn offered back to her like gifts. The shapes took another step. She closed her fingers hard around the pendant until the silver chain bit into her palm and waited for the moment she could move.
