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.

Aurora stepped between the standing stones and felt the cold leave her hands. The night had been sharp outside Richmond Park, damp enough to silver the grass and draw mist across the deer paths. Inside the ring, the air pressed against her skin with a different weight. It smelled of rain, crushed mint, and something sweet that reminded her of apples left too long in a cellar. She stopped. Behind her, the gap between the stones showed the park exactly as she had left it: black trees, a strip of wet path, Isolde’s lantern resting beside the moss-covered boundary stone. Then Nyx passed through. The shadow’s tall form folded around the edge of the nearest stone, thinning until only two violet eyes remained. They slid across the threshold. A breath later, the silhouette gathered itself again on Aurora’s other side. The park vanished. Aurora turned so quickly that the pendant struck her chest. The deep crimson stone pulsed beneath her coat, warm as a living thing. “Don’t touch the stones,” Isolde murmured. Aurora kept her hand near the silver chain without gripping it. “Where are we?” Isolde stood several paces ahead. Her silver hair spilled over her dark cloak and caught the colour of the sky. Her boots hovered above the ground. No footprints marked the pale soil beneath them. “Beyond the door, beneath the bough, where root and star entwine,” she replied. “You have crossed the place that opens only when it has closed.” Aurora glanced at Nyx. “That answer helped less than you think.” A faint breeze moved through Nyx’s body. Their voice arrived from several directions at once, soft as leaves scraping glass. “She means the boundary has sealed behind us.” The standing stones remained. They had changed, though. Each one now rose far above Aurora’s head, narrow and crooked, their surfaces rippling like dark water. Pale veins ran through the stone and glowed beneath the black crust. Isolde lifted her lantern. Its flame burned blue. “Walk with care. The Grove has no liking for haste.” Aurora drew the Fae-forged blade from its sheath at her hip. The moonsilver dagger felt cold enough to sting. Its leaf-shaped edge held a faint light of its own, a narrow gleam that sharpened whenever she looked towards the trees. The path ahead curved between trunks wider than houses. Their bark shone white, but not with the colour of birch. It looked like bone polished by centuries of rain. Branches stretched overhead and knitted into a ceiling crowded with tiny lights. Aurora watched one drift lower. It had wings like a moth, though its body was a glass bead filled with gold dust. When it brushed a leaf, the leaf chimed. Another answered. Then another. Within moments, the forest sang around them. The sounds did not form a tune. They rose and fell in scattered notes, some bright and thin, others deep enough to vibrate in Aurora’s ribs. Nyx tilted their head. “Those are not insects.” “I had noticed.” A shape moved between the trees. Aurora raised the blade. The thing stepped into the blue lantern light. It had four slender legs, a long neck, and a face without eyes. Blossoms grew from its brow. Their petals opened and shut with each breath. Isolde lowered Aurora’s wrist with two fingers. “Do not threaten the gardener.” The creature inclined its head. One of the flowers on its brow unfolded, revealing a dark centre filled with tiny teeth. Aurora stared at it. “Your gardener needs a warning sign.” The creature turned and walked away. Its hooves made no sound. Wherever they touched, pale flowers pushed through the soil. Nyx watched it disappear. “It is afraid.” “Of what?” The shadow’s violet eyes shifted towards the canopy. The lights above had stopped chiming. A low vibration travelled through the Grove. The white trunks tightened, their bark creaking like old ships in a storm. Somewhere beneath the ground, something exhaled. Isolde’s lantern flame bent towards the path. “Keep moving.” They followed. The Grove opened without warning. Aurora stepped from the white forest onto a slope overlooking a valley, and wonder stole the next breath from her lungs. The clearing stretched farther than Richmond Park could have held. Terraces descended into a basin filled with dark blue grass. Rivers of light wound between the hills, flowing uphill in luminous threads. Trees leaned over them, heavy with fruit that shifted colour as Aurora watched: red, then violet, then the silver-white of the moon. Above the valley, no sky existed. A vast sheet of stars hung close enough to touch. Constellations moved across it like schools of fish. One shape resembled a crowned stag. Another formed a woman with six arms. The stars rearranged themselves before Aurora could decide whether she recognised them. A waterfall poured from a cliff at the far end of the valley. It fell upward. The water gathered in a shining column, climbed into the dark, and vanished among the stars. Its spray drifted down in slow, glittering flakes. Aurora forgot the blade in her hand. “London’s parks never looked like this.” “They have not always looked as they do,” Isolde replied. Aurora looked over her shoulder. The standing stones were gone. Behind them, the forest had sealed itself into a wall of pale trunks. No path remained. “Isolde.” “I know.” Nyx moved to the edge of the slope. The ground dipped beneath their feet and then rose again, as if the soil had breathed. “Something has passed through here recently.” Aurora joined them. The grass felt warm through her boots. Each blade curled around her ankles before slipping free. Far below, a line of black marks crossed one of the glowing rivers. The marks looked like footprints, but each one had a narrow split down its centre. “Those belong to the gardener?” “No.” Isolde approached the marks. She made no sound as she descended the slope. Aurora followed, then caught herself. Her foot had landed in a patch of flowers. They snapped shut around her boot. She yanked free. The flowers opened again, displaying small, wet mouths. “Charming place.” “Do not insult what has not bitten you,” Isolde said. “It nearly did.” “Nearly is a courtesy.” The path down the slope twisted around terraces carved into the earth. Along the first terrace, silver trees grew in precise rows. Their fruit hung from bare branches, each one shaped like a human heart. Some beat beneath their skins. Others leaked dark juice onto the roots. Aurora’s pendant warmed. She pressed her palm against it. The crimson stone pulsed in time with the heart-shaped fruit. Nyx noticed. “Hel is close.” The word changed the valley. The warm air withdrew from Aurora’s face. The distant waterfall faltered, hanging motionless above the cliff. Every glass-winged creature in the canopy vanished into the leaves. Isolde reached for Aurora’s hand and turned it palm-up. Her gaze fixed on the pendant through the fabric of Aurora’s coat. “The stone remembers its birthplace.” “It was given to me.” “By a hand that wanted to remain unnamed.” “Do you know who?” “I know the lock. I know the key. I do not know the hand.” Aurora pulled her hand back. “And you brought me here anyway?” “I brought you where the road could be seen.” “By whom?” Isolde’s pale eyes lifted towards the moving stars. “By those who have forgotten how to look down.” A sound rolled across the valley. Not thunder. Laughter, deep and wet, rising from somewhere beneath the terraces. The heart-fruit began to beat faster. Nyx became less solid. Their outline blurred into the surrounding shadows. “Something heard us.” Aurora drew the pendant from beneath her coat. The crimson stone glowed through her fingers, throwing red light across the silver trees. At the bottom of the valley, one of the glowing rivers changed direction. It curled across the grass, climbed the terrace wall, and formed a narrow arch. Beyond the arch lay darkness. Not ordinary darkness. This blackness had depth. It folded in on itself, showing flashes of amber beyond: a sky the colour of old honey, rows of vines, a marble staircase, and figures moving beneath enormous trees. Heat spilled from the opening. It carried the scents of roasted spices, burning wine, and sweet fruit. Aurora’s skin prickled. The blade in her hand brightened. Isolde’s face tightened. “The road to Dymas.” Nyx’s voice thinned to a whisper. “And it has opened from this side.” The arch widened. Something stepped through. At first Aurora saw only a hand, broad and pale, with rings set into every finger. Then came an arm wrapped in dark red cloth, followed by a shoulder too large for any human frame. The figure ducked beneath the arch. Its head brushed the upper curve, and sparks scattered across the grass. It wore a chef’s coat stained black at the cuffs. A metal mask covered its face. The mask had no mouth, only a row of small vents that breathed out steam. In one hand, it held a silver platter. On the platter lay a cluster of red-black grapes. Each grape twitched. The masked figure turned towards Aurora. The pendant pulled against her grip, tugging towards the arch. She planted her boots in the soft earth. “Isolde.” The seer watched the figure without blinking. “The guest has brought a course,” she murmured. “The table has brought a knife.” Aurora raised the moonsilver blade. The figure lifted the platter. The grapes opened their tiny mouths.
