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.

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>

Aurora Carter stood with one hand on the cold flank of the last standing stone and looked into the clearing as if the place might change shape if she kept still long enough. It had not. The Fae Grove sat in the dark like a held breath. Moonlight spilled through the branches in thin silver bars, caught on wildflowers that should not have bloomed in late autumn, and pooled over the grass with a pale sheen that made every blade look damp. The ancient oaks ringed the clearing in a rough black wall. Their trunks leaned at angles no sane wood should manage, roots knuckling out of the soil like bones working free of skin. Rory let the stone go and rubbed her palm against her jeans. The drive out to Richmond had taken longer than it should have. The walk from the road had taken longer still. At the park gates, her phone had shown 11:12. By the time she found the standing stones, the screen had gone blank, then flashed 10:47, then died with half a battery left. “Brilliant.” Her voice landed flat. No echo. No bounce from the trees. The Grove swallowed sound and kept it. She reached beneath the collar of her jacket and pulled out the Heartstone pendant. The crimson gem sat in her palm, small as a thumbnail, its silver chain tangled around her fingers. It held a faint warmth, not enough to comfort. Just enough to feel alive. When she had crossed the line of stones, the pendant had started to pulse. Not bright. Not dramatic. A dull throb against her skin, like something waking under a blanket. That had been her reason for coming. Three nights ago, one of Yu-Fei’s late deliveries had sent her west, out towards a row of expensive houses backing onto parkland. She had cut through a narrow lane to save time, and the pendant had gone hot against her chest so fast she had gasped. She had followed the heat to the park railings and seen, far between the trees, a red light hanging low to the ground. Not a torch. Not a bicycle. A pinprick ember in the dark that blinked once and vanished. Tonight she had come back alone. That part now felt less like nerve and more like stupidity. Rory tucked the pendant back beneath her shirt and stepped into the clearing. The air changed at once. Outside the stones, the night had carried the wet London chill, with distant traffic and the occasional mutter of wind through bare branches. Inside, the cold sat deeper, older. The breeze did not cross the space. The flowers did not stir. Even her breathing sounded borrowed. She moved slowly, boots sinking a little into soft ground. The grass gave underfoot with a hush that reminded her of turning pages in a church. She scanned the ring of trees, then the centre of the Grove. Nothing. No red light. No opening in the air. No sign of anything at all. “Fine,” she muttered. “Love a waste of time.” She crouched and touched the earth. Dry. Warmer than it ought to be. She pinched a blue flower between finger and thumb. Its petals felt waxy, thick with sap. When she let go, it turned its face away from her hand. Rory froze. The flower settled, still as the rest. She stared at it until her eyes watered. “That did not happen.” The words sounded thin. She rose too fast, her knee cracking, and turned in a slow circle. The trees stood where they had stood. Moonlight striped the ground. The standing stones waited at the edge of the clearing, blunt and grey and solid. She fixed on them with relief, counted one, two, three, four— Five. She stopped. There had been four. Her stomach tightened. She counted again. The nearest oak blocked part of the ring, made the line uneven. She stepped sideways, craning her neck. Four stones. Rory blew out a breath through her nose and pressed the heel of her hand against one eye. “Get a grip.” Something clicked behind her. Not a branch. Too neat. Too deliberate. Like a fingernail tapping porcelain. She turned. Nothing stood there. Just the open patch of grass, white flowers nodding under moonlight. Then another click. To her left this time. She pivoted again. The sound did not come with movement, and that unsettled her more than if she had caught something darting between the trunks. Her own senses felt out of step with the place, each one half a beat late. “Who’s there?” No answer. A blackbird cried somewhere above her, one sharp note torn short. Silence rushed back in around it. Rory pulled her phone from her pocket out of habit. Dead screen. She angled it anyway, using it as a dark mirror to check behind her shoulder. All she caught was her own pale face and a strip of moon. She shoved it away and took three measured steps towards the centre of the clearing. The pendant gave another pulse against her sternum. Warmer now. Strong enough to notice through cloth. “All right,” she said, and this time she spoke to the thing under her shirt, not to the dark. “You dragged me out here. Do something useful.” The chain snagged as she drew it out again. The gem glowed faintly in her palm, crimson threaded with a deeper black at its core, as if smoke had been sealed inside glass. It tugged, not physically, not enough to move her hand, but her body answered all the same. Her gaze shifted towards the far side of the Grove. Between two oaks, the dark looked wrong. Not darker. Thinner. Like a patch in the night had worn through. Rory took one step towards it, then another. The pendant grew hotter. The skin beneath the gem prickled. Her scar on her left wrist ached, a small white crescent waking under old skin. The thin patch flickered. She stopped dead. A figure stood between the trees. Tall. Human shape. No details. Just a denser vertical slice of shadow where no one had stood a second before. Her throat tightened. She blinked. The space was empty. Rory did not move. Her hand closed around the Heartstone until the chain bit into her fingers. “You’re seeing things.” The sentence came out level. She clung to that. A whisper brushed past her right ear. Not words. Breath shaped into almost-speech. She flinched so hard her shoulders hitched up to her ears and spun with her forearm raised. No one. Nothing. The clearing remained open and bare. Her pulse battered at her neck. “Not funny.” The answer came from the trees ahead of her. A laugh. Soft. Female, perhaps. Or leaves rubbing together in a way leaves should never manage. It rose for a second, dipped, then stopped with a clean edge, as if a mouth had closed. Rory backed up one pace. Another. Her heel struck something solid. She jerked round, expecting stone. No standing stone stood behind her. Only open grass and flowers silvered by moonlight. Her breath caught. She knew where the stone should have been. Knew the exact spot where she had touched it. The ring had shifted. “No.” She turned slowly, searching the boundary. The stones stood farther away now, wider apart, half hidden by trunks that had not been there before. The clearing had stretched while she watched somewhere else. “That’s enough.” She headed for the nearest gap in the trees with quick, hard steps, keeping her eyes fixed on one lichen-covered stone as if concentration alone would hold it still. Ten paces. Twelve. The stone did not come any closer. The grass thickened around her boots. Stems brushed her calves. Flowers rose to her knees, then her thighs, white and blue and red, their faces tilting as she passed. Rory stopped. The clearing floor had been short and open seconds ago. Something moved through the flowers on her left. Not visible. Marked only by the ripple of stems bending in a line towards her. She staggered back. The ripple changed course with her. “Don’t.” Her voice cracked on the single word. She hated that. The moving line slowed. It sat there a yard away, hidden under blooms and leaves. The pendant burned in her fist. A smell reached her then, sudden and intimate. Damp soil. Crushed nettles. Under it, a sweet rot like fruit left in a warm room. Her skin crawled. “You wanted this,” she whispered to herself. “Portal, clue, weird magic. Congratulations.” The flowers ahead parted by an inch. She caught a glimpse of something pale close to the ground. A hand. No. Not a hand. Too many joints in the fingers. Too smooth. It folded back into the stems before she could fix its shape. Rory lurched away and nearly went down. The earth under one boot had turned soft as soaked cloth. She yanked her foot free with a wet sucking sound and found herself facing the centre of the Grove again. The middle was no longer empty. A low mound rose from the grass, covered in roots and wildflowers. It might have been there all along. It might have pushed up from the soil while she looked away. Moonlight glazed its curved top. At its base sat a narrow black slit, no wider than a fox den. Red light pulsed inside it. The Heartstone answered at once, heat flaring so sharp she hissed and nearly dropped it. There you are. The thought did not feel like hers. Rory’s jaw locked. She stared at the slit in the mound while the red glow beat once, twice, in time with the pendant. The whisper came again, this time from all around the clearing. Not one voice. Several. Layers of breath brushing over each other. “Laila.” She went still. Only one person had called her that in London, and she was not in Richmond Park at midnight. “Laila.” The second voice came from behind her, close enough to lift the hair at the back of her neck. Rory did not turn. Her fingers shook once. She crushed them tighter around the chain until the tremor stopped. “You’ve got the wrong girl.” A pause. Then, from her left, in a perfect copy of Eva’s voice, “Rory, don’t move.” Her stomach dropped. She turned anyway. Nothing stood there. Only flowers, waist-high now, their heads all angled towards her in a silent crowd. “Rory.” This time her own voice spoke from the far edge of the clearing. Same Cardiff edges. Same flat, clipped shape when she was angry. The sound of it peeled over her skin. She backed away from the flowers and hit something hard enough to bruise. A standing stone. It had reappeared at her spine without warning. She whipped round and slapped a hand against it. Cold grit. Ancient grooves under her palm. Real. The black slit in the mound widened by a fraction. A red seam shone through the opening, brighter than before. Not light cast on a surface. Light from depth. The sort that suggested distance where no distance should fit. The pendant grew so hot she snatched it away from her chest. Crimson light bled through her fingers. The whispers crowded in. “Open.” “Come through.” “Look.” “No,” Rory snapped, louder than she meant to, and the word cracked across the clearing like a plate thrown at stone. Everything stopped. No whisper. No movement in the flowers. No laugh in the trees. Even the pendant’s pulse paused. Rory stood with her back pressed to the standing stone, chest heaving, eyes fixed on the slit in the mound. From somewhere above her, in the branches of the nearest oak, something heavy shifted its weight. Bark creaked. Slowly, carefully, she lifted her gaze.
