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.

A character is alone in a strange, isolated place at night. They came here for a reason, but something feels off from the moment they arrive. The wrongness builds slowly — sounds that shouldn't be there, things that move at the edge of vision, a growing certainty that they are not alone. Build tension through restraint, not through gore. Use the codex entries above as your world reference for the character and setting. Only include the prose of the scene without any markdown or commentary. </instructions>

Rory parked the delivery bike beside the chained entrance to Richmond Park and checked the message again. North side. Past the old stones. Please come alone. I have your name. No number. No signature. The message had arrived through an account that vanished as soon as she opened it. She had come because of the last line. The park’s gates were locked. Beyond them, black branches stitched the sky together, and the path slipped between them without a lamp in sight. Rory swung one leg over the bike and tested the chain. It held. She could have left it there, called Eva, gone home to the flat above Silas’ bar. Instead, she tucked her phone into her coat and climbed over. Her shoes landed on wet grass. The cold had a damp, earthy bite that crept through the soles. She stood still and listened. A road hummed somewhere beyond the trees. A fox barked once, far off. Then the park swallowed both sounds. Rory switched on her phone’s torch and set out along the path. She knew Richmond Park well enough by daylight to find the north side, but night flattened its familiar shapes into a tangle of shadow. The torch beam picked out pale tree trunks and patches of mud. Her breath clouded the light. The message had mentioned old stones. There were plenty of old things in the park. She kept walking until the path forked around a stand of oaks. A narrow track ran between them, though she didn’t remember seeing it before. She stopped at its entrance. The trees crowded close. Their branches reached over the track and met above it, blocking the sky. Something glimmered beyond them, a faint blue-white point that might have been a reflector or a phone screen. Rory lifted her torch. The point vanished. “Nice try,” she said, and the words sounded small beneath the branches. She took the track. The ground grew softer. Leaves clung to the damp soles of her shoes, and the air smelled of crushed flowers. That made no sense. It was late autumn; nothing should have been flowering. Yet a sweet, green scent gathered around her with every step. Her phone lost its signal. She checked the screen, thumb hovering over Eva’s contact, then locked it. Calling into the dark would not make her feel safer. It would only give the dark something else to hear. The standing stones appeared without warning. They rose between the oaks, thick and grey, each taller than Rory. Their surfaces were scored with shallow grooves that caught the torchlight. Moss softened their edges. They formed a broken ring around a patch of open ground. Rory lowered the phone. Wildflowers filled the clearing. White, yellow, violet—small blossoms pressed through the grass, each one sharp and bright in the beam. Their petals trembled though the air stood still. She stepped over the boundary. The pendant warmed against her chest. Rory’s hand went to it through her coat. The Heartstone’s silver chain lay beneath her collar, the deep-red gem no bigger than her thumbnail. It had never warmed without reason. Near a Hel portal, it pulsed; elsewhere, it sat cold against her skin. Now a slow heat spread beneath her fingers. She turned back. The path between the stones looked narrower than it had from outside. The oaks beyond it seemed farther away. Rory stared at them until her eyes watered, then aimed her phone towards the clearing instead. “Who sent the message?” Her voice carried across the flowers. A soft scrape answered from beyond the stones. Rory spun towards it. The torch swung over trunks and undergrowth. Nothing moved. She took one step towards the nearest stone, keeping the clearing at her back. Another scrape came from her left. Not a branch dragged along bark. Not an animal rustling leaves. It sounded measured, like the slow pull of something heavy over gravel. She turned towards the sound. It stopped. The pendant pulsed once, warm and distinct beneath her palm. Rory backed towards the centre of the clearing. She didn’t run. Running would give the trees her back, and she had no intention of offering that. A shape crossed the far edge of her sight. She snapped the torch towards it. Empty ground. Flowers, stones, a strip of darkness between two oaks. “Come out,” she called. Her own voice seemed to travel farther than it should. It slipped beyond the clearing, through the trees, and did not return. A bird answered from above. Rory looked up. No branches shifted, no wings beat. The sound came again: a short, sharp chirp, then a second one, lower, from somewhere behind her. The first chirp came from the same place. She lowered the phone. “Birds don’t do that.” The flowers bowed. Not all at once. One cluster, then another, a narrow path bending in the grass as if someone walked through it. The movement circled the clearing, though nothing touched the stems. Rory’s fingers tightened around the phone. The scar on her left wrist caught on the edge of her coat cuff. She forced her hand to loosen. Panic would make her clumsy. She needed distance, a landmark, any sign the way out still existed. She turned towards the stones and found a figure standing between two of them. It wore a long, pale coat. Its face had no features Rory could make out, only a blur where the torch should have struck. The figure’s hands hung at its sides. Rory froze. The pendant’s heat sharpened. The gem pressed against her chest as if someone had hooked a finger through it and tugged. “Are you the one who sent the message?” The figure tilted its head. Rory took one step back. The figure stood closer than before. She had not seen it move. Her phone beam shook over its coat. The fabric looked soaked, though no water dripped from it. At its hem, grass bent beneath invisible weight. “Tell me your name.” The figure raised one hand and pointed at her. Rory followed the gesture to the Heartstone. Its inner glow seeped through her coat, a dim red light visible at the seams. The figure lowered its hand. The flowers stopped moving. For several seconds, the clearing held still. Rory heard her breath and the dry click of her phone’s camera adjusting focus. Then a sound came from behind the stones. Her own voice. “Who sent the message?” The words came from the trees, spoken in the same pitch and rhythm she had used. Not an echo. An imitation. Rory shifted her weight towards the nearest gap in the ring. The pale figure remained between the stones. “Move,” she said. The figure lifted its hand again, this time with its palm facing her. The phone screen went black. Rory pressed the power button. Nothing. She struck the side with her thumb, then stopped when the dark ahead brightened. A line of red light glowed beneath her coat. The Heartstone had begun to pulse. Warmth beat against her skin, slow and steady, each pulse brighter than the last. The pendant had never shone this strongly. She pulled it free of her collar. The silver chain slid through her fingers. The crimson gem lit the grass beneath her hand. The pale figure took a step forward. Rory backed away. Her heel touched a stone. The standing stone behind her felt warm. She turned and pressed her palm to it. The grooves in its surface were deeper than they had looked. They spiralled inward, meeting at a small hollow near the centre. The pendant tugged towards it. “No.” The figure took another step. Rory kept the pendant clenched in one hand and reached for the stone with the other. Its grooves shifted beneath her fingertips, not moving exactly, but changing where the lines led. They flowed towards the hollow like dark water. A low sound rose from beyond the ring. Three knocks. A pause. Three more. Someone on the other side of the trees, tapping on wood. Rory turned towards the entrance. The path between the oaks had vanished. A wall of trunks stood beyond the stones, packed so tightly together that no gap remained. She faced the figure again. It had stopped at the ring’s edge. The blur where its face should have been wavered, and Rory saw, for a moment, a mouth. It opened without showing teeth. “Rory.” The voice came from the figure and from the trees. It came from the stones under her palm. Every copy of it carried the same quiet familiarity. She did not answer. “Rory,” it repeated. “You came alone.” “Who are you?” The figure’s head turned slightly, as if listening to something behind it. A rustle stirred the flowers at Rory’s feet. She looked down. Their stems had bent away from the stones, all pointing towards her shoes. At the boundary, the first blossoms had begun to close. Her hand moved to the crescent scar on her wrist. The pendant burned against her fist. She opened her fingers before the heat could make her drop it. “Give it back,” the figure said. Rory stared at the shapeless face. “You sent me here for the pendant?” The figure did not move. A scrape sounded behind it. Then another. Something dragged itself across the ground beyond the stones, following the ring from the other side. Rory pressed the pendant into the hollow. The stone shuddered. The red light vanished. The clearing dropped into darkness. Rory heard the figure’s coat brush through the flowers, closer now, and the stones began to knock one by one around her. She snatched the pendant back out. Light returned in a sudden crimson flare. The figure stood at the ring’s edge, its pale coat stirring though the air remained still. Behind it, the oaks parted to reveal the narrow path. Rory ran. She crossed the flowers, slipped between two standing stones and hit the track at a sprint. Branches struck her shoulders. Her phone stayed dead in her hand. Behind her, the knocks followed—stone to stone, steady and patient. She reached the place where the path should have met the main track and stopped. The trees opened onto the clearing. The standing stones waited beneath the black branches. Wildflowers spread through the grass. At the far side, the pale figure stood with one hand raised. Rory’s breath caught in her throat. The pendant pulsed against her palm. From somewhere behind her, her own voice asked, “Who sent the message?”
