You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

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.

Aurora Carter crossed the boundary stones at 11:47 p.m. She knew the time because she had checked her phone twice on the walk from the Richmond road, then once more beneath the last working lamp. The screen had shown 11:46 when she left the path and 11:47 when the ancient oaks swallowed her. After that, the phone lost its signal. That was not unusual here. The Fae Grove had always disliked modern things. The first time Rory had come to the clearing, her battery had dropped from sixty-two percent to nine in less than an hour. The second time, her watch had stopped. Isolde had laughed when Rory complained. The Grove was old, she had said. It remembered when time belonged to something else. Tonight, Rory had not come to see Isolde. She stepped between two standing stones, their surfaces silvered by moonlight. The air changed immediately. Outside, Richmond Park had smelled of wet leaves, diesel from the distant road, and autumn soil. Inside, the air was warmer and sweet with flowers. Wildflowers crowded the clearing in impossible abundance: foxgloves, bluebells, buttercups, pale star-shaped blossoms Rory couldn’t name. They leaned beneath the oak branches as though listening. Their petals shone with dew, though no rain had fallen. The Grove should have been empty. That was why she had come. She tightened her fingers around the delivery bag slung across her body. It was empty except for a torch, a spare phone charger, and the Heartstone pendant. The pendant lay cold against her sternum, hidden beneath her black jumper. Its silver chain pressed lightly into the small crescent scar on her left wrist whenever she moved. She had brought it because it was the only thing she possessed that had ever reacted to the Hel portals. The last message from Eva had arrived at 9:13. DON’T COME TO THE BAR. DON’T CALL ME. IF YOU TRUST ME, TAKE THE STONE TO THE GROVE AND WAIT. No explanation. No sign-off. Just those words, followed by three unanswered calls. Eva had never been mysterious. Reckless, occasionally. Dramatic, often. But not mysterious. Rory had spent two hours trying to convince herself that this was some elaborate prank or a badly thought-out attempt to keep her away from danger. Then she had remembered Eva’s voice on the final call: breathless, low, and frightened. Wait in the Grove, she had said. If it starts glowing, leave. Rory had asked what would happen if she didn’t. Eva had hung up. Now the clearing held its breath around her. Rory walked toward the center, where a flat stone rose from the flowers like a table. She pulled out her phone. The screen remained black despite the battery symbol showing eighty-one percent. “Brilliant,” she muttered. Her voice carried farther than it should have. Something answered from the trees. Not a voice. A soft, deliberate rustle. Rory turned. The boundary stones stood behind her, unchanged. Beyond them, the woods were a wall of black trunks and tangled branches. Moonlight touched the first few yards, then gave up. She waited. Nothing moved. “Get a grip,” she whispered. The Grove had always produced sounds. A fox barking somewhere nearby. Wind in the canopy. The occasional crack of a branch under a deer’s weight. There was nothing supernatural about being uneasy in a dark wood, no matter what Isolde claimed. Rory took the pendant from beneath her jumper. The Heartstone was roughly the size of her thumbnail, a rough-cut crimson gem suspended from a silver chain. In daylight it looked like old glass. Here, it gave off a faint inner glow, red as a coal buried under ash. It was warm. Not faintly warm, as it usually became near a portal. Warm enough to make her skin prickle. Rory held it over the flat stone. The glow strengthened. Somewhere behind her, a twig snapped. She closed her hand around the pendant and turned again. The trees waited. She scanned them slowly, forcing herself to notice details. A pale trunk split by lightning. A low branch bent into a hook. A patch of darkness between two oaks. There. At the edge of her vision, something had moved. Rory looked directly at the gap. Nothing. Her heart beat once, hard. She set her bag on the stone and took out the torch. Its beam cut through the clearing, bleaching the flowers white. Dust or pollen drifted in the light. The beam reached the first line of trees and stopped there, as though the darkness had substance. She swept it left. Nothing. Right. Nothing. Behind her, a flower bent. Rory spun so fast the torch slipped in her hand. A path had appeared through the wildflowers. It ran from the far side of the clearing to the stone at her feet, narrow and perfectly straight. The flowers on either side stood upright, their stems unbroken. No footprints marked the dark soil. She had not seen it before. Her mouth dried. The path led to the trees. To a gap she was certain had not existed when she entered. The Heartstone pulsed in her fist. Once. Twice. The warmth traveled up her wrist. Rory glanced at her phone again. The screen had come alive. 12:02. She stared at it. Sixteen minutes. She had been inside for less than a quarter of an hour, but the moon had shifted across the clearing. It now hung above the western branches instead of behind her. The flowers seemed taller, brushing her knees. The phone clicked. A new notification appeared. NO SERVICE. Then, beneath it, another. MISSED CALL: AURORA CARTER. Rory stopped breathing. The number was hers. The phone began to ring. The sound was thin and old-fashioned, a mechanical trill that did not belong to the device in her hand. She let it ring once. Twice. The caller ID read AURORA CARTER. She declined the call. Immediately, it rang again. Rory backed away from the stone. Her heel caught a root, and she nearly fell. The torch beam jumped across the trees. For one instant, a figure stood among them. Tall. Narrow. Its head tilted too far to one side. Then the beam passed over the gap, and there was only a pale trunk. The phone stopped ringing. A voicemail notification appeared. Rory did not touch it. The screen lit her fingers blue. The scar on her wrist looked like a tiny white crescent. Something breathed in the trees. Not near her. Not far away. Everywhere. Rory slipped the phone into her pocket and picked up the bag. Her thoughts moved quickly despite the cold crawling over her skin. The boundary was behind her. She had crossed it less than twenty minutes ago. She could leave, reach the park, find a cab, go to Silas’s bar— The pendant pulsed again. The red glow shone through her closed fingers. A low vibration passed through the clearing. The flowers shivered. From the new path came a sound like footsteps. One. Two. Three. Measured. Unhurried. Rory raised the torch. The path remained empty. The footsteps continued, approaching from the trees. Four. Five. Six. She told herself it was an animal. A deer. A fox. Something small moving through the undergrowth, its steps magnified by the silence. Seven. Eight. The sound stopped halfway down the path. Rory’s grip tightened around the torch. “Eva?” she called. The word left her mouth and vanished. A reply came from behind the stone. “Rory?” Eva’s voice. Rory turned. No one stood there. The voice came again, closer. “Rory, don’t move.” She knew that voice. She knew the slight rasp beneath it, the way Eva softened the final consonants when she was tired. But the voice was coming from the flowers. Rory looked down. The blossoms around her shoes had closed. Every petal had folded inward, hiding their centers. They looked less like flowers now than small, clenched mouths. “Eva?” Rory said. The figure in the trees shifted. This time she saw it clearly. It stood between two oaks, too tall for the gap. Its arms hung straight at its sides. Its face was turned away, toward the boundary stones. Rory’s skin tightened. “Stay where you are,” Eva’s voice whispered from the ground. “It can’t see you if you don’t move.” The figure’s head rotated. Not its body. Only its head. It turned toward Rory in a slow, creaking arc. There was no face. The torch flickered. Rory fought the urge to look away. The thing’s features were not hidden in shadow; there were simply none. The front of its head was smooth and pale, like wax left unfinished. The Heartstone burned against her palm. The thing took one step. The flowers bent away from it. Rory moved. She ran for the boundary stones. The clearing stretched. Her first stride carried her across the path. Her second should have brought her to the stones, but they remained impossibly distant, their pale surfaces shrinking beneath the oaks. The air thickened in her lungs. The delivery bag struck her hip. Behind her, the thing began to walk. It did not hurry. That was worse than if it had chased her. Rory ran harder. Her shoes tore through the flowers. The torch beam bounced wildly, catching flashes of white petals, black branches, the smooth blank head gliding between the trees. The boundary stones did not grow closer. Her phone rang again. This time the sound came from ahead. Rory stopped. The standing stones were no longer behind her. They formed a rough circle around the far edge of the clearing, each one leaning inward. Her phone rang from the center of the circle. She knew then that the Grove had changed. Not moved. Not rearranged. Changed its mind about where the exit was. The blank-faced figure stopped at the edge of the flowers. Rory turned toward it, breathing hard. The Heartstone throbbed in her fist, each pulse matching the ringing phone. The thing lifted one long arm. Its hand pointed toward the stones. Toward the ringing. Rory looked at the pendant. The crimson gem glowed bright enough to paint her fingers red. A portal was near. Not behind her. Not ahead. Below. The flat stone at the center of the clearing had split open. A narrow black seam ran across its surface, widening with every pulse of the Heartstone. From the crack came a breath of air colder than winter, carrying the smell of iron and deep water. Eva had told her to wait in the Grove. She had not said where. The phone stopped ringing. In the sudden quiet, something began to knock beneath the stone. Three slow knocks. Rory stepped toward it. Behind her, the figure made a sound. It was not a growl or a scream. It was her own voice, speaking from very far away. “Rory,” it said. “You’re late.” The seam in the stone opened another inch. Rory looked at the blackness below and understood that the Grove had never been empty. It had only been waiting for her to arrive alone.
