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.

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 crossed beneath the ancient oak standing stones at 11:47 p.m. The last streetlamp vanished behind her. Its pale glow clung to the path for a few seconds, then the trees swallowed it. Richmond Park settled around her, vast and black, the grass silvered by moonlight. Beyond the stones, wildflowers crowded the clearing in colours that did not belong to any season: bluebells beneath the hawthorn, foxgloves beside winter daisies, white roses opening among the nettles. The Grove had always looked beautiful. Tonight, it looked as though beauty had been left out too long. Aurora stopped with one hand on the strap of her delivery bag. The leather creaked under her fingers. She listened. No traffic. No distant dog barking. No wind moving through the oaks. Her phone showed a dead signal and 11:47. She lifted it, waited, lowered it again. “Brilliant,” she murmured. The word fell flat. It did not travel beyond the standing stones. She had come because the pendant had warmed. It rested beneath her jumper on its silver chain, the deep crimson stone pressed against her sternum. Usually, the Heartstone stayed cold and heavy, an ugly little weight she had learned to ignore. Tonight it had pulsed against her skin from the moment she left the flat above Silas’ bar. By the time she reached Richmond, it had grown hot enough to sting. Hel portal. That was the only reason she had crossed into the Grove alone after dark. She had seen what the portals did. She had seen what came through them. She had also seen enough to understand that people who waited for trouble rarely survived it. Aurora stepped into the clearing. The air changed. It carried the scent of wet earth, though the ground remained dry beneath her boots. Something sweet lingered beneath it, like crushed violets left in a sealed room. She rubbed her thumb over the small crescent scar on her left wrist, a habit from childhood that appeared whenever her instincts began to scrape at her nerves. The boundary stood behind her, clear as a line drawn in ash. Ahead, the wildflowers bent away from her path. Not in the wind. There was no wind. Aurora kept walking. The trees formed a dark wall around the clearing. Their branches twisted together high overhead, hiding the sky except for narrow strips of moonlight. She knew the Grove held its own pocket of space between Earth and the Fae realm, but knowing it did not make the place feel less wrong. Time behaved badly here. An hour might pass while minutes slipped by outside, or a day might collapse into a breath. She checked the phone again. 11:47. The digits had not changed. “Come on,” she muttered, though she had no one to answer her. The pendant gave a faint pulse. Aurora reached beneath her jumper and closed her fingers around it. Warmth spread across her palm. The stone’s inner glow leaked through the gaps between her fingers, deep crimson, like a coal breathing under ash. A portal should have appeared somewhere nearby. The Grove usually announced one. Light bending. A pressure in the ears. The smell of metal and rain. She found none of it. Instead, she heard a footstep. Aurora froze. The sound came from behind her. One deliberate crunch through dead leaves. She turned. The path lay empty between the standing stones. Moonlight silvered the grasses. Nothing moved. Her breath tightened. She waited for another sound. A flower head dipped at the edge of the clearing. Aurora stared at it. The stem straightened. She drew the small folding knife from the side pocket of her bag. The blade clicked open. It would not help against most of the things she had encountered since leaving Cardiff, but holding it steadied her hand. “Isolde?” she called. The name belonged to the Grove’s keeper, though Aurora had never felt certain the woman had wanted visitors. Isolde had tolerated Rory’s questions and offered answers in the shape of riddles, but she had never invited her back. The trees offered no reply. Aurora turned towards the centre of the clearing. A circle of flat stones rested there, half-buried beneath flowers. She had found a portal there once, a thin vertical tear in the air that showed a place full of red light and distant, shifting silhouettes. The Heartstone had burned against her chest that night. Now the circle looked undisturbed. She approached it one step at a time. Her boots pressed the grass flat. Each footfall made no sound. Aurora glanced down. The flowers had curled around her soles. She lifted her foot. Their thin stems slid away from the tread and rose again, unbroken. A cold line passed between her shoulders. She moved faster. At the stone circle, she crouched and examined the ground. Black soil showed between the roots. No footprints. No scorch marks. No signs of a portal. The pendant pulsed again. This time, something answered. From the far side of the clearing came a soft knock. Aurora raised her head. Another knock. Wood against wood. She rose, knife held low. The sound came from one of the trees. Knock. Knock. Knock. Not a branch. The rhythm carried intention. Three strikes, a pause, then three more. Aurora’s mouth went dry. “Who’s there?” The tree answered with another set of knocks. A shape shifted beside its trunk. Aurora focused on it. A person stood there, narrow and tall, half-hidden behind the oak. A pale face showed between the branches. For one wild second, she thought it was Eva. Then the figure leaned out. The face remained blank. No eyes. No mouth. Only smooth, pale skin stretched over the shape of a human head. Aurora stepped back. The figure withdrew behind the tree. The flowers rustled. She swung the knife towards the movement. Nothing stood there now. The oak’s trunk split into two black ridges, its bark furrowed and ancient. A pale strip of fungus clung to the roots. Her phone vibrated. Aurora nearly dropped it. The screen showed an incoming call. EVA. Relief broke through her fear so quickly it hurt. She tapped accept. “Eva?” Static filled the clearing. Aurora pressed the phone harder to her ear. “Rory?” The voice sounded like Eva. The same low warmth. The same slight catch at the end of her name. Aurora’s grip tightened. “Where are you?” A pause. “Rory, I’m outside.” The voice came from the phone and from behind her. Aurora did not turn. The caller breathed against the back of her neck. She stepped forward, breaking the sensation. The breath vanished. Her phone still hissed in her hand. “Don’t move,” Eva’s voice whispered through the receiver. Aurora swallowed. “Are you in the Grove?” “I’m outside.” “Outside where?” “Outside you.” The words scraped through the speaker. Aurora ended the call. The screen returned to 11:47. A second later, the phone rang again. She switched it off. The ringing continued. It came from the grass. Aurora looked down. Her bag lay open at her feet. She had not dropped it. Inside, beneath the insulated lining and a spare rain jacket, her old mobile phone lit up. The screen glowed with Eva’s name. Aurora’s pulse struck hard against her throat. The old phone had no battery. She had kept it because Evan had smashed the newer one during the last month of their relationship, and the dead device held photographs she had never copied elsewhere. She had not charged it in two years. It rang again. Aurora kicked the bag shut. The sound stopped. Silence returned, deeper than before. She backed towards the stone circle, keeping her eyes on the trees. The shadows between them seemed denser now. Shapes formed and dissolved at their edges: a shoulder, a hand, the outline of someone standing with their forehead pressed against the bark. Each time she looked directly, there was nothing. The pendant burned. Aurora dragged it from beneath her jumper. The Heartstone glowed in her palm. Its crimson light fell over her fingers and the grass. At the centre of the stone circle, the air had begun to ripple. There. A vertical seam appeared between two stones. It looked no wider than a hair at first, a black line cutting through the moonlight. The line opened with a sound like fabric tearing underwater. The temperature dropped. Frost spread across the nearest flowers. Aurora crouched and reached for the seam. Something moved beyond it. She saw a corridor, or the suggestion of one. Red light shone along wet walls. A row of dark shapes stood in the distance, all facing the opening. One shape raised its arm. Aurora stopped. The pendant pulsed with such force that pain flashed through her chest. The figure beyond the seam tilted its head. Aurora pulled the stone away. The portal shuddered. The shapes came closer. “No,” she whispered. The seam widened. A hand pressed against the other side. Its fingers appeared long and jointed, the skin stretched thin over the knuckles. It traced the edge of the opening without crossing it. Aurora stood and backed away. The hand stopped. Behind her, the trees began to knock. Three strikes from the oak on her left. Three from the beech on her right. Then another set farther back. The sound travelled around the clearing, each tree answering the last. Aurora’s knife felt tiny in her grip. The portal breathed. A gust rolled through the clearing, though the flowers did not move. It carried the smell of wet stone and something older, something shut inside a cellar for years. The hand curled around the edge. Aurora glanced towards the boundary. The standing stones were less than thirty metres away. Between her and them, the flowers had grown tall enough to brush her knees. A woman stood among them. Aurora had not seen her arrive. She wore a dark coat buttoned to the throat. Straight black hair fell to her shoulders. In the moonlight, her face looked like Aurora’s own. The woman smiled. Aurora did not move. The stranger lifted one hand and pointed towards the portal. The gesture looked familiar. Patient. Almost kind. Then she pointed towards Aurora’s chest. The Heartstone flared. Aurora’s fingers closed around it. The woman’s smile widened, stretching past the shape a human mouth could hold. Aurora ran. The flowers clawed at her boots. She tore free and lunged towards the standing stones, the delivery bag striking her hip with every step. Behind her, the portal gave a wet, cracking sound. Something entered the clearing. Aurora did not look back. The boundary waited ahead, pale moonlight spilling between the oaks. She reached the first stone and slammed her palm against its cold surface. Her scar burned. The tree-knocking stopped. Every flower in the Grove turned towards her. Aurora looked over her shoulder. The clearing stood empty. The portal had vanished. The woman was gone. Only the flowers remained, their faces open beneath the moon. Then a voice spoke beside her ear. “Rory.” Aurora spun with the knife raised. No one stood there. Beyond the standing stones, the park had changed. The path no longer led towards the road. It disappeared into a thick stand of trees that had not existed when she arrived. Her phone clicked on in her pocket. The screen showed 11:48. Behind her, from the centre of the clearing, the old mobile phone began to ring.
