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>

Aurora Carter reached the standing stones at half past eleven, though the last message on her phone showed 10:47. She stopped beneath the first oak and read it again. The screen cast a pale square across her fingers. Battery: 62 per cent. Signal: none. The time remained 10:47, frozen beneath the date. “Brilliant,” she muttered. Richmond Park stretched behind her in a black, empty sweep. The path had vanished twenty paces back, swallowed by long grass and thorn bushes. Ahead, four ancient stones stood around a break in the trees. Their surfaces held the dull grey of old teeth. Moss climbed their sides in narrow strips, leaving the rest bare. The pendant rested against her sternum. Its silver chain had tangled in the collar of her jacket, and the deep crimson stone pressed warm through her shirt. Aurora touched it. The warmth had brought her here. For three nights, the Heartstone had stayed cold. Then, while she rode her bike back from a delivery to Golden Empress, it had pulsed against her skin. Once. Twice. A third time, strong enough to make her swerve into a parked car. She had almost ignored it. She had ignored stranger things since London. Then it had started pulsing again ten minutes ago. Now it beat beneath her fingers with a patient, living rhythm. Aurora lifted her torch and swept the beam across the stones. Nothing stood between them. The clearing beyond looked smaller than she remembered from the map, hardly large enough for the wildflowers gathered there in thick, bright clusters. White blossoms shone beneath the moon. Yellow heads nodded without wind. Blue flowers clustered around roots that rose from the soil like knuckles. The air smelled of wet leaves and something sweet beneath them. Not flowers. Honey, perhaps. Or fruit left too long in a bowl. She stepped between the stones. The torch flickered. Aurora paused with one boot lifted. The light steadied, then dimmed to a thin amber blade. Her phone still showed 10:47. She turned and looked back. The path had gone. A wall of oak trunks filled the gap between the stones. Their bark twisted into dark ridges. No grass bent where she had walked. No scuffed mud marked her route. She stood inside a ring of trees that had not been there thirty seconds earlier. Her breath clouded. She reached for her phone and opened the camera. The screen displayed the clearing, the stones, the flowers. Behind her, the oaks formed a solid wall. Aurora lowered the phone. The wall remained. “Fine,” she whispered. “That’s fine.” Her voice travelled farther than it should have. It slipped through the branches and came back from somewhere ahead. Fine. Aurora’s hand tightened around the torch. The echo had not sounded like her. She waited, listening. The grove held its breath. No insects chirred. No wind worried the leaves. Even the night beyond the trees had vanished. The park usually carried distant traffic, dogs, the low pulse of London. Here, the silence pressed against her ears until they hurt. The Heartstone warmed another degree. Aurora moved into the clearing. Her boots crushed no stems. The flowers leaned away from her soles, opening a narrow trail through the grass. She followed it without deciding to. The trail led towards the centre, where a low mound rose beneath an oak with a split trunk. Something had been carved into the bark. She lifted the torch. The beam shuddered over a circle of cuts, then a line beneath it. The marks resembled letters, but none belonged to an alphabet she knew. They had the sharp, hooked shape of bird tracks. A sound came from the left. A soft click. Aurora turned. Nothing moved among the flowers. She held the torch steady. White petals trembled near the edge of the beam. A dark shape passed behind them, low to the ground and quick enough to vanish before she focused on it. Her pulse climbed. “Hello?” The word fell flat. She waited for an animal to break cover. A fox. A badger. The sort of creature that belonged in a park at night. A second click answered from behind her. Aurora swung around. The standing stones stood empty. The oaks beyond them looked closer now, their trunks packed tight together. One stone had changed. A pale streak ran down its face, wet and glistening. She took one step back. Her heel touched something soft. Aurora froze, then looked down. A small white flower had curled around her boot. Its stem tightened as she watched. The petals folded into a fist. She kicked free. The plant snapped upright. Its petals opened. A whisper passed through the clearing. Not words. A sound like paper sliding beneath a door. Aurora raised the torch and backed towards the split oak. The beam skimmed the flower beds. Shapes shifted at their edges. Each time she looked directly at one, it became a stem, a leaf, a patch of shadow. When she moved the light away, something leaned into the darkness behind it. She pulled her phone from her pocket and pressed Eva’s name. The call failed before it rang. She tried again. This time, someone answered. Aurora lifted the phone to her ear. Static breathed against her cheek. “Eva?” The line remained open. A faint tapping sounded through the speaker. Three taps. A pause. Two taps. Then three again. Aurora lowered the phone and stared at the screen. The call timer had reached forty-eight seconds. She had heard no ringing. “Eva, if you’re there, talk to me.” The tapping stopped. A voice inhaled on the other end. Aurora backed away from the phone as if the breath had touched her face. “Who is this?” Silence. Then Eva’s voice came through, thin and distant. “Rory?” Aurora’s mouth went dry. “Where are you?” The voice crackled. Beneath it, something dragged across a hard surface. “Rory, don’t—” The call cut off. Aurora looked at the screen. The time still read 10:47. The battery had dropped to 59 per cent. She shoved the phone into her pocket and turned towards the boundary. The stones had moved. Not far. A few feet at most. Enough to close the gap between two of them. Enough to make the circle seem deliberate. She walked to the nearest opening and reached out with the torch. Its beam struck the oak beyond, then bent sideways, sliding across the bark as if the air had become glass. Aurora stopped before the threshold. The Heartstone pulsed. Warmth spread through her chest. For one instant, crimson light glowed beneath the stone’s surface. It revealed a thin red vein running through the gem, bright as a coal under ash. Something answered from beneath the ground. A deep knock travelled up through her boots. Aurora crouched and placed her palm against the soil. The earth felt cold. Damp. Then it shifted under her hand. Not like a tremor. Like a breath. She jerked upright. The flowers all faced her. Every white, yellow, and blue bloom had turned on its stem. Their dark centres watched from the grass. Aurora stood with her back pressed to the split oak. The bark snagged her jacket. A sharp branch scraped her wrist, just above the small crescent scar she had carried since childhood. The clearing remained still. Then the tree behind her whispered. “Rory.” She tore away from the trunk. The voice had come from inside it. Aurora stared at the split in the oak. The dark opening ran from the roots to shoulder height. It looked deep enough to hide a person. No, not a person. The darkness inside seemed to continue beyond the tree, descending into a place without walls. Her torch beam reached into it and disappeared. “Rory.” This time the voice used her mother’s tone. Aurora’s fingers went numb around the torch. “Don’t,” she breathed. The split widened with a slow wooden groan. A strip of bark peeled inward. Something pale showed beneath it. A hand, perhaps, though the fingers had too many joints and rested at the wrong angle. Aurora stepped back. The hand withdrew. The tree closed. The flowers turned away from her. For several seconds, nothing happened. Aurora’s lungs worked in short, useless pulls. She forced her knees to unlock and moved towards the stones. The ground resisted each step. Not mud. Not roots. A pressure beneath the soles of her boots, pushing back. She raised the torch. A figure stood between the trees. It faced away from her. Aurora stopped. The figure wore a dark coat. Its shoulders sloped beneath the fabric. Black hair fell to the middle of its back, straight and shining in the weak light. Aurora looked down at herself. Her jacket was zipped to the throat. Her own hair brushed her shoulders. The figure stood twenty feet away, framed between two oaks. “Who are you?” Aurora called. The figure did not move. The Heartstone beat once. The figure’s head tilted. Aurora took a step towards the nearest standing stone. The figure’s head tilted farther, until the angle became impossible. A thin crack sounded from its neck. Aurora backed away. The figure raised one arm and pointed towards the gap in the stones. A second arm unfolded from beneath its coat. Then a third. Aurora’s torch flickered again. In the darkness between flashes, the figure stood closer. In the brief amber light, it remained in the same place. The distance between those two facts tightened around her. She turned towards the stones. The gap had vanished. A smooth black surface filled the space, reflective as deep water. The trees behind it showed no reflection. Neither did she. Only the Heartstone appeared there, glowing crimson against an empty, faceless shape where her body should have been. Aurora stopped three paces from the surface. Behind her, the figure made a wet clicking sound. The pendant pulsed against her chest. The black surface rippled. Something on the other side placed a hand against it. Five long fingers pressed outward, followed by a sixth that slid into view beneath the palm. Aurora raised the torch. The reflected hand curled. Her phone vibrated in her pocket. Once. Twice. A message arrived. She pulled it free. The screen showed a photograph of the clearing taken from behind her. The image captured the stones, the flowers, the black surface—and Aurora standing with her back to the camera. A pale face hovered inches behind her shoulder. The message contained one line. RORY, TURN AROUND.
