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 grove took her the moment she crossed the last line of trees. One second Rory was in Richmond Park, the night heavy with damp grass and the dull amber wash of distant lamps beyond the road, and the next she was standing inside a pocket of stillness that felt stitched into the dark. The air changed first. It thinned, somehow, though it was colder too, carrying the clean bite of soil and wet bark and something sweet underneath, like flowers crushed between fingers. Wildflowers, she thought vaguely, absurdly. It was the wrong season for them, but the ground at her feet was speckled with pale blooms anyway, their petals silvered by moonlight. She stopped just past the standing stones. Ancient oaks, someone had once told her. The trunks rose from the earth in a crooked ring, thick and pale with age, their bark furrowed as deeply as hands gone to bone. They leaned inward over the clearing like old witnesses. Rory had to tilt her head back to see the tops of them, and even then the canopy was a black tangle against a blacker sky. No wind moved. No insects sang. Behind her, the park had gone strangely far away. She could still see the suggestion of trees through the gap between the trunks, but the path she’d followed in was already hard to make out, as if the grove had decided not to remember how she entered. Rory pressed her tongue to the back of her teeth and kept herself from looking over her shoulder again. She’d checked twice already. There was nothing there the first time and nothing there the second, and she knew from experience that the third check was how panic made itself useful. The pendant hung cold against her sternum beneath her shirt. Not cold exactly. Cool, then warm, then cool again, each pulse faint enough that she might have imagined it if the chain didn’t shift with it, a tiny silver tug against her skin. She lifted a hand and touched the Heartstone through the fabric, feeling the small, hard shape of it with her fingertips. It answered with a throb of heat that spread quick as breath. That had been the reason, then. That and the note. Come alone after dark. If you want to know what the pendant is, go to the grove. No signature. No explanation. Just enough to make her skin prickle and enough of a lead to make her ignore the voice in her head that had said do not, do not, do not. Rory let her hand drop and took a step farther into the clearing. The ground was springy under her shoes, soft with moss and roots. The wildflowers grew thick between the stones, white and violet and a yellow so bright it almost hurt to look at. Moonlight laid a sheen over everything, but the light didn’t seem to come from the sky alone. It hovered in the grasses, in the gaps between roots, as if the clearing was remembering day and using the memory badly. She drew a slow breath through her nose and listened. At first there was only her own breathing. Then the faint click of her shoe against a root. Then, after a pause so long it became suspect, the distant wash of traffic from beyond the park, muffled and warped, as if heard through water. London belonged somewhere out there. Here, it sounded old and tired and very far away. She should have felt relieved to be alone. Instead the solitude pressed at her ribs. Rory crossed her arms and rubbed her hands along her forearms, trying to get warm. The sleeves of her jacket had ridden up, exposing the crescent scar on her left wrist. She glanced at it automatically, as if the pale mark might tell her she was being stupid. It didn’t. The skin looked ordinary, the scar a small broken line in the moonlight. Her pendant pulsed again. This time the warmth was stronger, a distinct little flare against her chest. Rory stilled. She could almost swear the glow under the fabric brightened, a muted ember behind her shirt. Right. That was useful. Or would be, if she knew what she was looking for. She turned slowly in a circle. Standing stones. Trees. Flowers. Dark. More dark. The same six or seven shapes repeated in slightly different arrangements because her eyes couldn’t settle on them long enough to hold still. One of the oaks on the far side of the clearing had a split in its trunk, and for one ridiculous, specific instant it looked like a doorway left open into pitch-black space. Rory blinked and it was only bark again. She frowned and kept her gaze on it a moment too long. The bark seemed to ripple. A trick of shadow, she told herself. Her heartbeat had picked up, and her pulse felt too loud in her throat. A sound came from behind her. Not a footstep. Not quite. More like fabric brushing grass. Rory went still. The clearing held its breath with her. She did not turn around. Every sensible instinct in her body had converged into a single sharp instruction: do not give whatever it is what it wants by showing it you know it’s there. Another sound. A soft scuff. Then the faintest crack of a twig. Her mouth had gone dry. She counted to three in her head, then to five, forcing her breathing slower, quieter. There was no reason for anyone to be here. She had come in alone. She had seen no one on the path, no cyclist, no dog walker, no late-night idiot cutting through the park. The grove had been empty. She turned anyway, sharply enough that her hair swung against her jaw. Nothing. The standing stones marked the edge of the clearing in a rough ring, and between them the park was a dark blur of trunks and shadow. No movement. No shape. No pair of eyes reflecting back at her. The grass behind her was untouched. Rory stared for another few seconds, feeling foolish and not reassured in the least. Then she heard it again. This time from the left. A slow dragging brush across leaves. She pivoted toward the sound, breath catching, and found only a hawthorn branch dipping low under its own weight, its leaves trembling though no breeze touched them. The branch settled while she watched it, too late and too deliberate to be random. A laugh, thin as breath, ticked somewhere beyond the stones. Rory’s stomach tightened hard enough to hurt. No. She had not come all this way to startle herself into seeing things. The grove was odd. That was established. Time moved strangely here. The place was Fae-touched or pocketed or whatever the correct word was for a bit of the world that behaved like a lie. The pendant warmed near whatever it was meant to find. That didn’t mean there was something in the dark. It meant there could be. That thought landed with such force she nearly laughed at herself. It wasn’t funny. Her fingers curled around the strap of her bag. She’d brought a torch, a phone with more battery than sense, and a lighter she didn’t know how to use for anything useful, which felt like the sum of all adult preparedness. She pulled her phone free and unlocked it. No signal, of course. The screen threw a pale rectangle across her hands. In that narrow light the grove looked worse, not better. The shadows became layered, full of seams. The flowers at her feet shone white along their edges, like tiny wet teeth. Rory swept the torch function on. The beam cut a clean path through the clearing. For one second, she saw the whole place in hard detail: the rough grain of the stones, the roots lifting from the earth like knuckles, the close-packed flowers nodding in the beam. Then something crossed the light at the very edge of her vision. Rory jerked the torch toward it. The beam hit empty grass. She stood frozen, every muscle wired tight. She had not seen a body, not really. Just a thinning, a suggestion, the impression of something too tall and too narrow to be a tree moving where no thing should move. The torchlight trembled in her hand. A note of sound drifted through the clearing. Not a laugh this time. A hum. Soft. Near. Almost familiar. Rory’s throat closed. The hum changed pitch. It was a little like someone trying to remember a tune, a tune she knew she knew but could not place. The sound seemed to come from all around her and nowhere at once, slipping between the standing stones and under the roots. The pendant against her chest grew steadily warmer, then hot enough that she flinched and grabbed for it through her shirt. “Okay,” she whispered, and the word came out too small to be courage. “Okay. Very funny. If this is supposed to be helpful, it’s not.” The hum stopped. Silence dropped so abruptly she almost stumbled into it. Then, from behind the nearest standing stone, something answered in her own voice. “Rory.” She went cold all at once. Her entire body had the horrible urge to turn and flee, which meant it was probably the wrong move. Her brain searched madly for explanations and found none that made sense. Echo. Trick of the grove. Memory. Her mind misfiring under stress. Anything. The voice came again, softer this time, almost patient. “Rory.” Not her mother’s accent. Not her father’s. Not Eva’s. Just hers, pitched a little lower, stretched strange at the edges as if it had been spoken through water. The name came from somewhere just beyond the stone, from a place her torch did not quite illuminate. The pendant burned against her skin. Rory looked down despite herself. Through the fabric she could see the faintest red glow, a tiny heartbeat of light. It was brighter now, no longer just warm. It beat in time with something else she could feel, a second pulse somewhere out in the grove. Slowly, very slowly, she lifted the torch again. The beam struck the standing stone to her right. At first it was only grey bark and lichen and moss. Then she saw the hand. It was low on the stone, partly in shadow, fingers splayed as if someone had just placed it there to steady themselves. Rory stopped breathing. The hand was pale, almost luminous in the torchlight, and too still. She could not see the arm attached to it, only the faint outline of fingertips around the stone’s edge. It did not move when she stared. It did not flinch away from the light. It simply remained there, waiting. Her mind had the ridiculous, frantic thought that it looked like a child’s hand. Small. Delicate. Wrong in the way the moonlight was wrong. A second later the fingers flexed. Not a wave. Not a grasp. Just a slow, testing curl, as if whatever belonged to them had discovered she was watching. Rory took one step back. Her heel struck something soft. She looked down and nearly dropped the torch. Footprints marked the grass behind her. Bare footprints, damp and dark, leading from the stones to where she stood. She had not made them. The soil around them was flattened in a line that curved around the clearing, circling her. They had been there long enough for the edges to sink, long enough for dew to gather in them. She could see the print of toes, the arch, the heel. They were not hers. Too long in the toes. Too narrow. The line of prints ended at the space immediately behind her. Rory did not move. The world had narrowed to the sound of her own blood and the heat of the pendant against her chest. Behind her, very near her ear, someone exhaled. No touch. No breeze. Just a warm, damp breath that was not hers and did not belong to anything human she knew. Her phone slipped in her hand. The screen went dark. In the black reflection, Rory saw a shape over her shoulder. She turned before she could stop herself. The torch beam swung wildly, catching only the trunks, the stones, the flowers. Nothing stood where the reflection had suggested a figure. Nothing stood in the clearing at all except her and the dark and the impossible ring of trees. But the footprints had moved. They were no longer behind her. They were in front of her now, closing the distance by inches across the grass. Rory backed up until the edge of a stone pressed into her spine. Her lungs pulled too shallowly. The torch shook in her grip, slicing the clearing into flashing pieces. The footprints stopped. Then the voice spoke again, not from behind this time, but from the trees. “Come closer.” It sounded like her own mouth had formed the words a moment after the fact. It sounded calm. Certain. Rory stared into the dark between two trunks and saw, for one blink, the faint outline of a person standing there. Not a person. A shape shaped like one. Tall. Still. Watching. The Heartstone flared hot enough to make her gasp. And from somewhere deep in the grove, beyond the standing stones and the whispering flowers, something else began to answer, a slow deliberate chorus of footsteps coming toward her through the dark.
