You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

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. </instructions>

The fence at Richmond Park stood too high after dark. Too official. Rory ducked under anyway, where the wire sagged near the horse trail. Her trainers hit leaf-mulch on the other side and sank. The mud sucked at the soles. She steadied herself against a trunk and checked the phone. No signal. The screen showed 23:47 and then went black to save power. She shoved it in the pocket of her delivery jacket. The jacket still smelled of fried rice and rain from the last Golden Empress run. Yu-Fei had asked where she was headed. She had given a vague answer. The Heartstone hung outside her collar, too warm for the night air. Its crimson caught no light and yet made its own, a dull throb against her sternum. The pulse matched nothing in her chest and pulled. Not a tug at the chain. A lean in her bones toward the interior of the park. Rory had not meant to come back to the Grove. Not at night. Not after what Eva told her about time inside it. But the pendant burned through her shift, hot enough to leave a mark, and when she held it up it swung south-west and held, steady as a compass needle. So she came. The path ended fifty metres in. Beyond that, deer track braided through gorse. Her breath clouded. It was May and her breath clouded. The oaks that marked the boundary rose from the dark without shape at first, then with too much shape. They were not trees planted by a landscaper. Their trunks split and fused and formed something like lintels. The air between them rippled. It hurt her teeth to look at it. Rory stopped at the threshold. Wildflowers crowded the arch, open in the dark. White stars and yellow cups and a violet she did not know the name of. All in full bloom. All year-round bloom, Eva had said. Something in the pattern was wrong. The flowers faced the gap in the stones. Not the moon. The gap. "Yeah, no. That is not how phototropism works." Her voice cracked the quiet. It sounded small. Beyond the stones, the clearing was darker than the park around it. That made no sense. Fewer trees. More sky. The darkness inside the Grove had weight. The Heartstone flared against her skin. A hot spot the size of a thumbnail. Rory stepped through. Cold bit her ankles first. Then her knees. The air on the other side had a different texture, slick, like water without wetness. Sound dropped out. No distant traffic off the A3. No planes. No wind in the high branches. Her ears rang to fill the loss. The clearing held. Grass brushed her shins. Same flowers, but now their heads all bowed low, as if pressed down by a hand. The ancient oaks circled tight. Too tight. She counted six. She remembered eight. Her left wrist itched. She scratched at the crescent scar there and left a white line in the skin. "Hello?" No echo. She took another step. A twig snapped underfoot with a clean, loud pop. Too loud for a twig. Too sharp, like a bone giving way under pressure. The Heartstone pulsed. The light inside it beat once. Twice. And held, bright. In the corner of her eye, something shifted between two oaks. Not a deer. Too tall. Too thin to be a trunk. Rory turned her head. Nothing. Grass. Stone. Flowers. Her pulse hammered against her throat. She forced her chin down and her shoulders back, the old trick from the flat above Silas's bar when footsteps lingered too long on the stairs at 2 a.m. She walked to the centre. The place where Isolde had bled, or danced, or whatever Eva's half-story had been. The ground dipped. The grass was flat there, as if something had lain there for a long time and then stood. A sound rose. It started beneath the threshold of hearing, then resolved into a wet, soft drag. Grass parting. A heel through mud. The rhythm had a pause in it that a human walk does not have. Step. Step. Rest. Step. Rory spun. The gap between the stones stood empty. The flowers still faced it. The sound came from behind her. She spun again. "You hear that too, right?" The question was for the pendant. The pendant burned. The Grove was not empty. The wrongness was not that something had entered. The wrongness was that the space between things was too full. The air between the oaks had a denseness, a presence that displaced light. At the edge of vision, the standing stones flexed. She blinked hard. The stones were still stone. Lichen and bark and rot. But the bark split while she looked at it and the lichen pulsed with the pendant. "Stop that." Her hand closed around the Heartstone. The metal bit into her palm. The heat stung. A new noise. A low rustle, as if wind moved through leaves that did not move. Then a distinct inhalation. Slow. Long. That ended with a catch, like a throat full of earth. It stood right behind her. Rory knew without turning. The back of her neck prickled. The hair on her arms rose. The grass at her heels bent inward under weight that had no feet. The scent hit next. Damp soil after a storm, leaf-mould, and under that a sharp copper tang. Old blood. She jerked forward two paces. Her boot slipped. She caught herself on her hands. The grass was cold and slick. The pendant swung free of her shirt and cast a red wash across the flattening where something had lain. In that red light she saw the imprint was not one shape. It was many. Overlapping. Pressed and pressed again into the same hollow. Some smaller than her hand. Some longer than her body. And all of them fresh, the crushed stems still weeping green. Movement again. Left. Right. Both sides in sync. The flowers shivered. The drag resumed. Closer. Step. Drag. Rest. Step. Drag. Rest. She pushed to her feet and backed toward the stones. Her shoulder struck oak and she flinched away; the bark was warm, damp as skin. "Who is there? Show yourself." Her voice filled the Grove and died without edge. No reverb. The clearing ate sound. The pulse in the pendant turned frantic. Heat spiked to pain. She let go with a hiss. The chain seared a thin line across her collar bone. A shape detached from the dark between two oaks where no shape should exist. Not coming forward. Unfolding. The height of it made her tilt her chin up. Up and up. Limbs that bent at joints too many and too low. It did not step into the red light. It stayed where the dark was thickest. Where the air was full. It breathed. She saw no eyes. She felt being seen. The wildflowers turned. Every single head in the clearing, in a single smooth motion, swivelled to point at her. Petals stared. Rory's legs gave for a half-second and locked again. Cool reason slid over panic in a cold sheet, the way it always had since Cardiff, since Evan, since law tutorials where she learned to talk while her hands shook out of sight. She counted to three and forced air through her teeth. "If you want it, you have to come get it." She held the Heartstone out. The crimson light painted her knuckles, her scar, the black of her jacket sleeve. The thing between the oaks leaned. The drag came again, nearer still. The grass in front of her parted, stalk by stalk, in a line toward her boots though nothing touched it. The pendant beat like a live heart trapped in crystal.
