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 stood nine deep, their oak split and silvered by centuries, and the air between them thickened like breath held in winter. Rory stopped at the boundary with one boot planted on the grass of Richmond Park and the other hovering over nothing. The ground on the far side was the same ground, but it looked wetter, greener, and somehow closer to her face. "Walk through or stand there looking clever," Nyx said. Their voice slid over her skin like a draught under a door. Their shape folded and unfolded at the edge of the nearest stone, a tall smear of living dark that drank the afternoon light. "Either way, the trees will still be here when you decide." "They won't," Isolde said. "The trees here have never been anywhere else." She had not made a sound coming down the slope. Rory had heard nothing but the wind through the bracken and the distant hum of a tourist's electric bike on the road. Now the seer stood among the stones, silver hair falling to her waist, pale lavender eyes fixed on the gap between two monoliths. Rory glanced down at the damp earth around Isolde's bare feet. The grass dipped under the weight of her own boots. It did not dip under the seer. "You're doing the thing," Rory said. "The one where you don't leave marks." "I am standing still. Standing still leaves no marks. Walking is the vulgar part." Rory huffed through her nose. Her left wrist ached where the old crescent scar pulled, the way it always did when something stood too close to the Veil. She rolled the sleeve of her jacket higher and looked at the air above the stones. Most people would have seen nothing but a warm haze and blamed their eyes. With her sight open, the Veil showed itself as a shimmer, like heat rising off tarmac, rippling in a slow pattern that did not match the wind. "It's thinner today," she said. "It is thinner in the morning and thicker at dusk," Isolde said. "Like everything that is honest with you. Do you want to go in, Malphora, or do you want to count the stones until your courage runs out?" "Don't call me that." "Then do not behave as if the name fits." Nyx laughed, a sound like dry leaves caught in a gutter. Their form drew up tall and then settled, pouring itself across the grass until it reached the first stone. Their violet eyes flickered in the dimness that had not been there a moment before. "Come on, then. I'd rather be bored in there than bored out here." Rory stepped through. The cold hit her first, not the cold of the November air she had left behind, but a clean, mineral chill that rinsed the taste of exhaust from her mouth. Then the sound arrived. Water ran somewhere close and fast, and beneath it something chimed, low and patient, like a glass rim touched by a wet finger. She turned in a slow circle. The stones stood behind her, exactly where they had been, but the view beyond them had changed. Wildflowers covered the slope in drifts of blue and white and a red so bright it looked wet. Yet the trees above them were heavy with blossom and bare of leaves at the same time, and a single brown oak leaf spun down through the branches in no particular hurry. "Don't touch the flowers," Isolde said. "Most of them will tell you a story. Few stories end well for the listener." Rory kept her hands in her pockets. Her fingers found the Heartstone pendant, and the silver chain pressed a faint line into her palm. The stone felt warm, warmer than her skin, and it glowed through the fabric like an ember behind a sheet of paper. That was not right here. The pendant warmed near Hel portals, not near grass and bells. "Is it supposed to do that?" she asked. "It is supposed to remember," Nyx said. Their shadow stretched across the path ahead, longer than the sun could account for. "Things that come from Dymas always do. They never forget a feast." Rory pulled her hand free and drew the Fae blade from the sheath at her hip. The moonsilver came out with a whisper. Even in the grey daylight it held a faint luminescence, a pale edge that seemed to drink what little brightness there was. The steel was cold enough to ache against her palm. Good. Cold meant it was working. Cold meant it was listening. They followed the path deeper. Isolde moved ahead without a sound, her hair rippling in a breeze that did not touch anyone else. Rory noticed the trail beneath her own feet slowly changed texture, moss giving way to something smoother, like polished stone worn by countless passing steps. Carved into the rim of the path were symbols she almost recognised, looping script that folded back on itself the longer she stared. She tore her eyes away before the lines could settle into words. "What are these?" she asked. "Directions," Isolde said, "for those who are already lost." "That's not an answer." "It is the only honest answer I have that you would want." Ahead, the trees thinned and opened onto a clearing. Light fell differently there, not from above but from every side at once, pale and even, as if the sky had been poured into a bowl. A pool lay at the centre, perfectly still, its surface reflecting not the bare branches overhead but a sky the colour of old honey, streaked with a sunset that Rory was certain had not happened yet. At the pool's edge, half-sunk in the reeds, stood a stone bench worn smooth by something other than weather. Nyx stopped at the tree line. Their form rippled and then thinned, and for a moment Rory saw the shadows of the trees pass straight through their body. "I know that bench," they said quietly. "I have sat on it before, a long time ago, when I still had a face to make the choice with." Rory looked at the pool, and then at the bench, and then at the seer, whose lavender eyes had turned to the water with something close to grief. "Isolde," Rory said. "Tell me what happened here."
