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 standing stones rose out of the bracken like the ribs of some long-dead giant, each oak weathered to silver-grey and taller than any tree had a right to be. Rory stopped at the threshold between two of them, her breath fogging in air that had no business being cold in June. "You feel that?" She pressed a hand to her chest. Beneath her jacket, the Heartstone pulsed once, warm against her sternum, then went still. "It went quiet. Like it's holding its breath." Nyx flowed past her, their silhouette darkening where the dappled light should have touched them. "Different rules here. The pendant knows it." Their voice came thin, frayed at the edges, as though the place itself swallowed sound. "I can barely slip the shadows. They don't lie the way they should." "Comforting." She stepped through. The world changed between one footfall and the next. Behind her lay Richmond Park — joggers, dog walkers, the distant grumble of the South Circular. Ahead spread a clearing that should not have fit inside the ring of stones. Wildflowers carpeted the ground in colours she had no names for, blues that shaded into something past violet, petals that turned to follow her instead of the sun. The grass gave off light where she crushed it, a soft phosphorescence that faded as she lifted her boot. "Don't touch anything," Nyx murmured. "Wasn't planning to." She crouched anyway, hovering a fingertip above a bloom that breathed — actually breathed, the petals swelling and shrinking in a slow rhythm. "Eva would lose her mind." "Your friend is sensible enough to be elsewhere." The third of them said nothing. Silas had stayed near the boundary, one broad hand braced against an oak, his jaw tight. Bar owners weren't supposed to look afraid of anything. He looked afraid now. "You coming?" Rory called back. "Give me a minute." He pushed off the stone, rolling his shoulders. "Places like this. They don't forget who walks through. You leave a mark, they keep it." "You've been here before?" "Somewhere like it. Long time ago." He didn't elaborate, and she'd learned not to press. They moved deeper. The light here came from no single source — it welled up from the flowers, dripped from the canopy of a single vast tree at the clearing's heart, hung suspended in motes that drifted past her face like dust caught in a window's beam. The air tasted of crushed mint and something older, mineral, like rain on hot stone. Somewhere water ran, though she couldn't see it, a thread of sound that seemed to circle them no matter which way they turned. "Time's wrong here." Nyx had gone still, their violet eyes pulsing brighter. "Listen." She did. And realised the birdsong she'd taken for granted came from no birds. It looped — the same trilling phrase, perfect, repeating with the precision of a recording. Beautiful and dead at once. "How long have we been walking?" she asked. "That's the question, isn't it." Silas checked his watch, then tapped its face. The second hand jittered, lurched backwards, settled. "Right. Useless." "An hour in here could be a week out there." She wiped her palms on her jeans. "Or a minute. Eva won't even know I'm gone. Or she'll have buried me already." "Then we don't dawdle." Nyx slid ahead, a darkness gliding over the luminous grass without bending a single blade. "She'll be near the tree. They always nest at the centre of these things." The great tree dominated the far side of the clearing, its trunk wide as a house, its bark scrolled with patterns that resolved into faces if she stared too long — and dissolved the moment she did. Its roots arched and dipped through the earth like the coils of some sleeping serpent, and between them grew a curtain of hanging blossoms, white turning gold at the tips. Rory reached out before she could stop herself. The blossom nearest her hand turned, the way a person turns at the touch of a stranger's gaze, and unfurled to show a centre that gleamed wet and red as a wound. "Rory." Silas's hand closed on her wrist. Hard. "What did I just say." "It moved towards me." "That's exactly why." He drew her back. His grip pressed against the crescent scar on her wrist and she winced, pulling free. "Sorry. But this place wants you curious. Curious is how it keeps people." A laugh drifted across the clearing — low, amused, ageless. "He's right, you know." Rory spun. The woman stood between two roots where there'd been nothing a heartbeat before. Silver hair fell past her waist, stirring in a wind that touched nothing else. Her eyes were the pale lavender of the flowers underfoot, and where she stood the grass kept its light, undisturbed. No footprints marked her path. No path existed. "Isolde." Nyx inclined what passed for their head. "We've come a long way." "You've come no distance at all, Nightwhisper. You've merely stepped sideways." Isolde's gaze settled on Rory, and something behind it caught and held, as though she recognised a face she'd seen only in dreams. "And you've brought the one who carries Dymas against her heart. Bold. Or foolish. The Veil thins, and the warmth of that stone draws eyes that should stay shut." Rory's hand went to the pendant. "Then you know why we're here." "I know a great many things. Whether I'll tell them is another matter entirely." A smile touched her lips, neither warm nor cruel. "You crushed my flowers walking in. Three steps off the safe ground. The grove remembers." "It glowed," Rory said. "I didn't know." "No. You didn't." Isolde turned, beckoning with one slender hand, and the curtain of blossoms parted without her touching it. "Few do, the first time. Come. The light is failing, which means nothing here, and everything. Walk where I walk. Touch nothing else. And perhaps — perhaps — I'll show you what you came to find before the grove decides it would rather keep you." Behind them, the standing stones had vanished. Only the breathing flowers remained, and the false birdsong, looping its perfect, hollow song.
