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 shoved through the last tangle of branches and stepped into the open space between the ancient oak standing stones. Richmond Park stretched silent and vast behind her but the grove swallowed every trace of the city. The Heartstone Pendant burned against her chest with each step she took from her flat above Silas' bar. Its pull had dragged her out after midnight with the crimson gem flashing like a signal fire. Answers waited here. The unknown benefactor who left the artifact on her doorstep clearly meant this place for her. Wildflowers blanketed the ground in every direction. Their petals stretched wide under moonlight that should not reach them. Blues bled into reds and yellows that pulsed with inner light. The air tasted thick enough to chew. From the first contact of her boot with the soil the wrongness settled in her gut. The flowers bent away from her path before she reached them. No wind explained the motion. She swept her torch across the clearing. The beam looked thinner than it should as if the darkness drank whatever it touched. A low hum vibrated up through her legs. The sound stopped the instant she noticed it. When she shifted her weight the hum returned from a different spot nearer the stones. Rory kept her shoulders squared. "This is the spot the pendant chose. No point flinching now." The words dropped dead in the heavy air. She advanced to the center where the flowers grew tallest. Their stems brushed her palms with unnatural warmth. One bloom detached and floated upward spinning in place. She watched it rise until the dark claimed it. A rustle broke out to her left. She pivoted the torch. Nothing stirred among the stems. The beam caught only the faint glow of more petals turning their faces toward her. Another rustle came from behind. She spun again. The flowers stood motionless. Their centers looked too round. Too focused. Her left wrist itched beneath the small crescent scar. She rubbed at it without thinking. The mark felt hot to the touch the way it had the night Evan raised his voice one time too many and she decided London offered escape. The memory flashed sharp then vanished. The pendant throbbed faster. Its silver chain grew warm against her neck. She lifted the gem and let its faint inner light spill across the ground. For a breath the entire grove brightened. Tall shapes scattered at the edges of the stones. They moved with joints that bent in too many places. The light faded and the shapes melted back into nothing. Rory exhaled through her teeth. "Show me what you brought me for." No voice answered. Instead the rustling multiplied. It circled her at the distance of ten paces then eight. She tracked it with her ears because her eyes found nothing every time she looked straight on. At the corner of her vision a sliver of movement flickered. Pale fabric or perhaps skin. It disappeared when she turned. The stones seemed closer than when she entered. Their carved spirals caught the pendant's glow and sent it back twisted into new patterns that hurt to follow. She stepped toward the nearest one. The soil under her boots made a wet sound like lips parting. She stopped. A whisper slid past her ear. The sound formed her name but stretched the syllables until they no longer fit a human mouth. She jerked her head. Cold air brushed the back of her neck then retreated. "Who uses that name here?" The question hung unanswered. The flowers nearest her feet closed their petals tight with soft clicks that reminded her of locks engaging. Further out the blooms opened wider. Their centers reflected her torch beam like dozens of tiny mirrors. She paced a slow circle. Her delivery bike waited chained to a tree beyond the park boundary. Yu-Fei would notice her absence from the Golden Empress route soon enough. The thought brought no comfort. Time behaved wrong inside these stones. An hour here might stretch into days outside or collapse into minutes. Her phone screen showed nothing but a frozen clock. The certainty crept higher. She was not alone. The knowledge sat behind her eyes refusing to leave. Every time she faced one direction the rustling intensified in the opposite. Shapes darted between the oaks at the limit of her sight. They never resolved into clear forms. Just impressions. A shoulder. The curve of an antler made from twisted branch. A smile that carried too many teeth. Rory clenched her jaw. "I came for the portal the stone reacts to. Not games." The pendant flared so bright it lit the underside of the canopy. In that burst she counted seven figures standing among the flowers. They vanished the moment the light dimmed leaving only the echo of their presence in the bent stems. Her scar flared in perfect time with the gem. The crescent shape cast its own faint red light onto her sleeve. She pushed the fabric back and stared at the mark. It had never done that before. The childhood fall her father described never explained why the scar sometimes looked too clean. Too deliberate. A laugh drifted from the direction of the largest stone. The sound copied her own voice from years ago when she and Eva played in the Welsh hills. The copy carried an extra layer like an overtone that set her teeth on edge. She aimed her torch at the stone. The beam died without warning. She shook the cylinder. Fresh batteries should have lasted longer. The plastic grew cold in her grip. Rory dropped the useless torch. The pendant and her scar provided the only illumination now. Crimson washed the flowers turning their petals the color of raw meat. She refused to think the comparison. Instead she focused on the way the stems leaned together forming arrows that all pointed outward. Another touch ghosted across her shoulder. Fingers too long traced the line of her collar then withdrew. She did not slap at the empty space this time. She turned instead with deliberate care. The air displaced beside her. A patch of colder night slid past and reformed behind the nearest standing stone. The carvings on its surface pulsed once in greeting. "I see you." She spoke the words to the stone. The rustling stopped. Total silence rushed in to fill the gap. In that quiet she heard two heartbeats. One belonged to her. The other beat slower from everywhere at once. The flowers began to wilt in a ring around her boots. Gray spread through the petals then reversed. Fresh green shoots pushed upward twisting into shapes that mimicked hands. She stepped out of the circle before they finished forming. The new growth followed. Each flower that sprouted reached for the hem of her jacket. She kept moving. The standing stones rotated positions without ever showing the motion. What had been the exit now faced a solid wall of oak and rock. Her wrist burned hotter. The scar split along its length though no blood welled. Crimson light poured from the opening and braided itself with the pendant's glow. The combined light revealed movement on every side. The figures no longer bothered to hide at the edges. They stood among the flowers in a loose ring. Their bodies suggested height and grace but the angles of their limbs refused human logic. Rory lifted her chin. The cool-headed focus that carried her through pre-law exams and the train ride away from Cardiff locked into place. "Tell me why the stone led me here." The figures tilted their heads in unison. The motion looked copied from something that learned human posture from books. One of them extended a hand. The fingers numbered six and bent backward at the final joint. It pointed at the pendant then at the scar on her wrist. A whisper slid directly into her ear though no one stood close enough to speak. "Key." The single word vibrated through her skull. She refused to flinch. Instead she studied the space between the figures searching for gaps wide enough to slip through. The flowers had grown taller in the last minutes. Their stems formed a living maze that shifted whenever her attention moved. Another laugh broke out. This one came from above. She looked up. Shapes clung to the branches like spiders made of moonlight and leaf litter. They dropped from sight before she could count them. The second heartbeat grew louder. It matched the pendant's rhythm now. Her own pulse fought to stay independent but the sound dragged it into line. Her steps slowed. The soil clung to her boots with new purpose. Rory reached the largest stone and pressed her palm to its surface. The carvings lit beneath her skin. Images flashed through her mind. Other women with black hair and bright blue eyes standing in this same clearing. Each wore a similar pendant. None of them left. She yanked her hand away. The connection severed with a sound like tearing paper. The figures had closed half the distance while her attention wandered. Their circle tightened without any of them appearing to take a step. She spoke again to keep her thoughts ordered. "My name is Aurora Carter. I deliver food for Yu-Fei Cheung. I live above a bar. Those things are real. This is a trick." The figures paused. One cocked its head so far the motion should have snapped its neck. The face stayed hidden in shadow but she felt the weight of its regard slide across her skin like oil. A breeze moved through the grove for the first time. It carried her own scent back to her mixed with something sweeter that coated her tongue. The wildflowers bowed low then sprang upright in waves that rippled outward. Each wave ended at the feet of the figures. Her scar continued to pour light. The pendant swung on its chain as if caught in a wind she could not feel. Both pulled her toward the narrow gap that had just opened between two stones. An exit. Or a deeper trap. Rory planted her feet. The soil pulsed beneath her like a vein. She would not run. Running handed them power. She had fled Evan once. That escape carried her this far but the grove demanded something different. The figures resumed their approach. Their forms stayed just beyond clear sight. Details refused to resolve. She caught the curve of a shoulder here the suggestion of a mouth there. Each glimpse left an afterimage that lingered on her retinas. The second heartbeat filled the clearing now. It shook the petals from the tallest flowers and sent them spinning upward in a vortex that blocked the moonlight completely. Crimson light from her wrist and the pendant became the only color left in the world. She kept her breathing even. "Whatever you think I am the answer is no." The vortex slowed. The figures stood ten paces away. Their circle locked tight. One extended its impossible hand again. This time the palm turned upward in clear invitation. Rory stared at the offered hand. The skin looked like bark stretched over light. Veins of deeper green ran beneath the surface. The fingers flexed once. The rustling returned softer now. It came from inside her own jacket. She looked down. The pendant swung harder. Its chain links scraped together in a rhythm that matched the new heartbeat. Her scar widened further. Light poured out and formed threads that reached toward the nearest figure. She took one step back. The soil rose to meet her boot and held it fast. Another step proved impossible. The flowers wove around her ankles without touching her skin. Their touch carried no weight yet she could not lift her feet. The figures waited. The invitation remained open. The grove held its breath along with her. Rory met the blank space where their eyes should be. Her mind raced through every out-of-the-box angle she possessed. The stones. The flowers. The time difference. The pendant that clearly belonged to them. Every path led back to the same conclusion. She had arrived for a reason that was never hers to choose. The light from her wrist braided tighter with the gem. The threads stretched across the narrowing gap between her and the circle of figures. One thread made contact. The effect rolled through the clearing like a stone dropped into still water. Every flower opened at once. Their centers locked onto her face. The second heartbeat became a drum that shook her bones. The figures leaned forward in perfect unison. Rory kept her eyes open. The wrongness that began the moment she crossed the stones now lived inside her chest. It wore her pulse like a coat. It watched the grove through her bright blue gaze. The night refused to end.
