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 oak standing stones stood in a crooked line beneath the Richmond Park trees. Their trunks had been dead for centuries, yet their bark held a sheen like wet bronze. Deep grooves ran along them in the pattern of roots, and pale moss filled the cuts. Aurora stopped before the gap between the two tallest. “Those weren’t here on the way in.” Nyx’s violet eyes rested on the stones. Their shadowed shoulders shifted, edges loosening into wisps that crawled over the grass. “They were,” they breathed. “You simply had no reason to see them.” The park behind them smelled of rain and clipped grass. Beyond the stones, the air shimmered. Aurora could make out the trees on the far side, but their trunks bent at angles that made her eyes ache. The distortion crawled over the view like heat above a road. Isolde waited on the other side. Her silver hair fell to her waist, bright against the dark branches. No grass bent beneath her bare feet. “Come, little flame. The gate opens for those who know they have arrived.” Aurora glanced at the narrow path between the stones. “That sounds like the sort of thing people say before a gate eats you.” “Then keep your fingers close,” Nyx whispered. Isolde smiled, and the corner of her mouth lifted as if she’d heard a private joke. Aurora touched the silver chain at her throat. The Heartstone rested beneath her shirt, cool against her skin. She slid the Fae-forged blade from its sheath. Moonlight caught the leaf-shaped edge, though the sky above the park was clouded. Isolde’s pale eyes settled on it. “Cold iron cuts the door, but moonsilver remembers the hand that opened it.” “Is that a warning?” “It is a truth with its coat turned inside out.” “Useful.” Aurora crossed first. The air tightened around her. For one breath, she felt pressure in her ears and a sharp taste of pennies on her tongue. Then the pressure broke. She stepped onto soil soft as sifted flour. Behind her, Nyx passed through without a sound. Their shape drew thin as smoke between the stones, then gathered again beside her. Isolde came last. The space where she’d stood on the far side remained empty, though Aurora had watched her step forward. The park had vanished. A clearing spread beneath a sky the colour of tarnished pearl. Wildflowers covered the ground, blue and gold and a red so deep it seemed to drink the light. Their stems brushed Aurora’s boots. She bent to touch one, but the petals folded shut before her fingers reached them. “Do they bite?” she asked. “Only when they mistake a hand for a bee.” Aurora pulled back. “And how often does that happen?” “Less than you fear. More than you’d like.” Nyx looked up. “The sky has no sun.” “No,” Aurora said. “It has something pretending.” A pale disk hung behind a veil of drifting clouds. It gave no warmth. Yet the clearing smelled of summer: crushed clover, sap, and flowers opening after rain. Aurora turned to look for the standing stones. They were still there, but the gaps between them had narrowed to slits. Through one, she glimpsed the park’s ordinary trees, dark and distant, as if reflected in deep water. Isolde moved into the flowers. No stem bent beneath her steps. “Stay where the ground is kind,” she called. “The kind ground lets you leave.” “What does the unkind ground do?” Aurora followed, keeping the blade in hand. “It keeps what it loves.” Nyx drifted along at Aurora’s shoulder. Their shadow lay in two directions at once: one stretching across the flowerbed, the other reaching toward the treeline. The path rose and fell without hills. Every few paces, Aurora’s boots sank into earth that felt warm through the soles, then crossed patches cold enough to sting. She heard the soft click of insects, though none appeared. Somewhere ahead, water ran with the hollow resonance of a glass struck by a spoon. They passed a tree split from crown to root. Silver leaves hung from one half; the other bore small white blossoms. The trunk was wide enough to shelter a room. A band of carved symbols circled it, each mark worn almost smooth. Aurora slowed. “Those look like writing.” “They were once names,” Isolde replied. “The tree remembers the mouths that spoke them.” A whisper slipped from the bark. Aurora caught no words, only the sound of a crowd murmuring behind a closed door. She stepped away. Nyx pressed one palm to the trunk. Their fingers sank into its shadow. The tree shivered. Every silver leaf turned toward them. “Don’t,” Aurora snapped. Nyx withdrew. The leaves turned back, one by one. “Something below it had a pulse,” they said. “Roots?” “Not roots.” Isolde continued down the path. “Some doors grow tall. Some grow deep.” Aurora glanced at the tree again. A narrow seam ran along its base, black as a cut in cloth. The whisper stopped. The path led them beneath an arch of intertwined branches. Beyond it, the ground dropped into a shallow basin filled with water. The pool reflected no sky. Its surface held a field of stars, bright enough to sting Aurora’s eyes. She crouched at the edge. The stars shifted when she moved, but the reflection showed her kneeling from above, with Nyx behind her and Isolde farther back. The reflected Isolde stood with one hand raised. Aurora looked over her shoulder. Isolde’s hands hung at her sides. The reflection lifted its hand higher. Aurora rose. The image followed a beat later. “Is this a trick?” “The water shows what it can reach,” Isolde replied. “That’s not an answer.” “It is the answer I have.” Nyx leaned over the pool. Their violet eyes glimmered in the reflected stars. The image beneath the water did not resemble them. It showed a tall figure in a dark coat, with a human face and a ring of pale light around its head. Nyx jerked back. The ripples spread, breaking the image apart. “Was that you?” The shadow along their jaw tightened. “Once.” Aurora put the blade between Nyx and the pool, though she knew it would do nothing against water. The silver edge caught the reflected stars and held them in a bright line. Isolde watched the blade. “Some mirrors return a face. Others return the road that face abandoned.” Nyx turned away from the pool. “We’re done here.” Aurora studied them. Their outline had gone ragged, fraying at the shoulders. “We don’t have to touch anything else.” “We have touched enough.” Isolde’s gaze settled on the path ahead. “Enough is a cup with a crack. It empties before the thirst.” “Then we’ll keep to the path,” Aurora replied. “No trees, no pools, no mysterious whispers.” A faint smile crossed Isolde’s face. “A fine list. The place has heard it and will do its best to oblige.” The path curved around the basin. Each step carried them farther from the stones, though the clearing stayed within sight behind them. Its flowers had closed, their dark petals turned toward the ground. A line of pale pillars stood ahead. Aurora counted nine, then ten, though there had been nine a moment before. They were not stone. Their surfaces looked like bone polished by a river, and fine veins of green light ran beneath them. Each pillar rose from a patch of bare soil. No grass grew within a few feet of their bases. A low hum filled the air. Aurora’s teeth began to ache. “Are those graves?” she asked. “Not all,” Isolde answered. “Which ones aren’t?” “The ones that still answer.” A sound came from between the pillars: three clear notes, like someone playing a flute from the bottom of a well. The blade chilled Aurora’s palm. Its pale glow brightened along the edge. Nyx’s shadow gathered close around their feet. Isolde stopped at the first pillar and lifted her face to the hum. “Listen before you enter,” she said. “The old stones have more than one voice.”
