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.

By the time Aurora reached the old oaks at the edge of Richmond Park, the city had thinned to a smear of orange light behind the trees. The last bus had dropped her near the road, and she had walked the rest with her delivery rucksack hanging from one shoulder and the Heartstone pendant tucked under her jumper, warm against her skin in a way that had stopped feeling accidental an hour ago. She stood before the ring of ancient oak stones and looked at them without moving. In daylight they would have passed for some half-forgotten bit of park oddity, weathered posts sunk into the earth by a council that liked heritage plaques and tidy legends. At night they looked older than the ground. Thick. Dark. Their surfaces held the moon like wet skin. Moss filled the grooves in them. Something pale grew at their bases, not fungus, not flowers, something between the two, folded like ears. The pendant gave a slow pulse. Aurora drew it out on its silver chain. The deep crimson stone held a faint glow of its own, dull as banked coal. Heat pressed into her palm. “Fine,” she muttered. “You dragged me here. Now do something useful.” The words vanished the moment they left her mouth. No bounce. No rustle after. The park behind her still carried the far hush of tyres, a dog bark, a train grinding over track. Inside the ring, silence sat in one piece. That wrongness hit first. Not fear. Not yet. Just the sense that the world had been cut with a sharp knife and one side of the cut had forgotten sound. She slipped between two of the standing stones. Cold air met her, though the grove itself looked untouched by the season. Wildflowers spread through the clearing in dense, impossible drifts. Foxgloves. Bluebells. Poppies. Crocus heads. White stars she didn’t know. They crowded one another without regard for month or soil, colour layered over colour until the ground looked painted. Frost silvered the grass outside the boundary. Inside, the petals stood open and fresh as if noon burned over them. Aurora took three steps and stopped. The smell came next. Not earth. Not leaves. The place smelled of crushed stems and old water, but beneath that lay something metallic and sweet, like pennies held in the mouth. She checked her phone. 11:18. No signal. “Of course.” She pocketed it and looked back at the gap she had crossed through. The two oak stones stood where they should have stood. Beyond them, the park waited under the same moon. Nothing had changed. Then she heard a footstep behind her. Not loud. A soft press in the flowers. A bend of stems. Someone placing weight with care. Aurora turned so fast the rucksack slipped down her arm. Nothing stood there. Only the path she had made through the blooms and the black trunks crowding the outer ring. Her own breath came shallow for a beat, then settled. “Deer.” The word felt stupid here. Deer moved with snorts and brittle cracking sounds. This had sounded human. Still, she latched on to it and moved deeper into the grove, keeping one hand on the pendant, one hand free. She had not come on a dare or a whim. For three days the Heartstone had warmed whenever she crossed the western side of the city. Near Hammersmith it had ticked with heat. On the bus through Barnes it had grown hotter. Tonight, when the route curved past Richmond, it had burned against her chest hard enough that she had hissed and nearly dropped the fare machine in a passenger’s lap. Yu-Fei had told her to go home after her shift. Instead, she had got off at the next stop and followed the pull on the chain like an idiot with a compass. Now that she stood in the clearing, the stone beat in her hand with a slow, living warmth. Not Hel, she thought. Not unless Hel had learned to wear perfume and flowers. The idea should have steadied her. It did not. A stem brushed her ankle. Aurora looked down. The flowers around her had bent away from her boots, making a narrow lane. Not enough to clear a path. Enough to suggest one. She crouched and touched a bluebell head. Cool. Real. Dew beaded her fingertip. From somewhere to her left came the click of glass meeting wood. She froze. The sound arrived again. A neat, familiar ring, exactly like a pint glass landing on Silas’s bar top downstairs from her flat. Aurora stayed crouched. “No.” Silence answered. Then, from farther in, came the scrape of metal against a wok. A fast toss. Two hard knocks. Steam hissing over flame. Yu-Fei’s kitchen. Golden Empress at seven on a Friday. Aurora straightened with a sharp breath. “Who’s there?” Petals shifted in the dark. No voice came back. No body stepped out. The sounds had already died, but the memory of them stayed, bright and exact, too exact. She could have named the plates from the chime alone. The pendant flared hotter. She took the lane the flowers offered. The grove widened without her noticing the change. One moment the standing stones ringed her at a comfortable distance. The next, the nearest one stood twenty paces off and the far side had gone. Tree trunks should have marked the boundary beyond the flowers. She saw none. Only blackness between stems, layered and flat as folded cloth. Her steps made almost no noise. The ground felt springy beneath the soles of her boots, like damp turf laid over something hollow. She stopped again and listened. For a few seconds she heard nothing at all. Then a second set of steps matched her last two, one beat late. Crush. Crush. Aurora’s shoulders locked. She did not turn this time. She watched the flowers ahead of her, watched for movement, watched the edge of vision where shapes had room to lie. “Not clever.” Her voice held. Good. She clung to that. To her right, something black slipped between two stands of foxglove. Thin. Quick. Shoulder height. It moved with intent, not drift. Aurora whipped round. A dead branch jutted from the earth, twisted into the shape of a bent arm. She stared until her eyes watered. The branch did not move. Her left wrist prickled where the old crescent scar sat pale against her skin. She rubbed it hard with her thumb and forced herself to breathe through her nose. Phone. Torch. Map. All the sensible bits. She hauled the mobile out again. The screen lit her hand and chin. 11:18. The numbers changed while she watched. 11:19. 03:07. 11:18. The light shook across the flowers. “No, you don’t.” She backed a step, thumbed the torch on, and swung the beam in a clean arc. White light cut over blossoms, oak bark, a spill of white petals on the ground that looked almost like scraps of paper. Nothing human. Nothing large. Nothing alive except the flowers and a single moth that flashed past the beam and vanished into the dark. When she lowered the phone, one of the standing stones stood closer than before. Not by much. A pace. Two at most. Enough that she knew it had not been there. Aurora stared at the stone, then at the others. Their spacing had gone wrong. The ring no longer made a ring. Gaps opened where there should have been wood. Two stones leaned inward like listeners. The metallic sweetness in the air thickened. A knock sounded behind her. Three taps. Soft. Measured. Knuckles on old wood. Aurora shut her eyes for one hard second. She knew that knock. Evan had always used that knock after he’d promised he was calm. When she turned, the nearest stone stood in darkness with moonlight catching its damp grain. No door. No flat. No narrow hall. Yet the knock came again from its centre, as if something on the other side wanted letting through. Aurora took a step back. “Don’t do that.” The stone held still. From somewhere beyond it, low and near, her own voice answered. “Don’t do that.” Every hair on her arms rose. The imitation had been close. Not close enough. The pitch missed by a thread. The shape of the words came out smooth, as if a mouth that had never used language had found the trick and liked it. Aurora set her jaw. “If you want something, come out where I can see you.” The flowers to her left bowed all at once, as if a hand passed over them. “See you.” This time the voice came from the flowers themselves. Thin. Breathless. Not hers now. Not anyone’s. Aurora moved. Fast, controlled, choosing a direction at random because staying still felt like stepping into wet cement. She headed for what should have been the boundary, eyes on the nearest pair of stones. The ground lengthened under her. The stones never got closer. She stopped before panic could take the wheel. Panic made people stupid. She had survived worse things than a haunted patch of park by not giving panic the steering wheel. The pendant burned in her fist. Aurora looked down. Crimson light leaked between her fingers. That had changed too. The Heartstone had glowed before, faint and shy. Now a deep red throb ran through it, each pulse casting blood-dark colour across her knuckles. The wildflowers nearest her folded in on themselves at each beat. Petals drew tight. Stems bent away. “Right,” she whispered. “So it’s you.” She opened her hand. The stone lay against her palm, hot enough to sting. Its silver chain hung in a bright line. Deep within the red, something moved. Not a reflection. Not trapped light. A shape crossed the heart of the gem and was gone before she could make sense of it. Behind her, the late footstep came again. Crush. Closer. Aurora did not turn. She lifted the pendant out before her like a ward, absurd and instinctive, and watched the red light spill over the flowers. Another sound answered from the dark ahead. A breath drawn through teeth. Then, clear as if someone stood over her shoulder, her mother’s voice spoke into her left ear. “Aurora.” She spun and slashed the torch beam across the clearing. The light hit stone, bark, and a stand of white flowers that had not been there a moment earlier. In their midst stood a shape with her height and her build, black hair cut to the shoulder, one hand lifted at its throat as if it too held a chain. The beam touched it for half a second. Its face had no features. Moonlight pressed into a blank oval where eyes and mouth should have been. The torch jerked in her hand. The beam skipped away. When it landed back, the flowers stood alone, their white heads nodding. Aurora’s mouth had gone dry. “Not real.” The words scraped out. From all around the grove, in a dozen stolen voices, the answer came back. “Not real.” The standing stones gave a low wooden groan, not from strain but from movement, the sound old ships made in harbours at night. Aurora backed until her heel struck one of them. Cold soaked through her coat. The grove had tightened around her. The stones stood close enough now that she could have touched two without stretching. The flowers between them swayed though no wind crossed the clearing. The black spaces beyond the ring had thickened into solid dark. She held the pendant higher. Red light pooled over the nearest stone. Lines showed in the oak grain. Not natural. Not carved by weather. Long shallow marks crossed and recrossed each other at shoulder height, hundreds of them, as if nails had dragged there over years. Aurora’s stomach turned. A soft laugh rose from behind the stone. Not Evan. Not Silas. Not anyone she knew. It sounded young, then old, then neither, and stopped with a wet little click of teeth. “Enough,” she snapped, and her voice came back to her stronger than she felt. “Show me what you are.” The flowers ahead bent apart. Something stepped into the narrow gap they made. Not fully. It let her see only pieces: the line of a shoulder where no body should have fit, fingers too long resting on a standing stone, blackness folding around a shape that would not stay the same from one blink to the next. When she tried to look at its face, her eyes slid off as if the thing had greased the air around it. The Heartstone pulsed so hard it hurt. The thing took one more step. Behind Aurora, another set of feet stopped two paces back. Warm breath touched the nape of her neck.
