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 reached the standing stones at eleven forty-three, according to her phone. She checked because the walk from the park gate had taken longer than it should have. Her torch had picked out the same split oak three times, though she was certain she hadn’t turned. The stones rose between the trees like trunks that had forgotten how to grow. Their surfaces held the ridges of bark, but they were cold and hard beneath her fingers. Beyond them lay the clearing. She had come to find out whether the pendant would warm here. That afternoon, while making a delivery past Richmond Park, she’d felt heat beneath her shirt. It had faded as soon as she crossed the road. She could have put it down to the weather if the silver chain hadn’t been cold against her neck at the time. The stone was meant to react to a portal to Hel. Rory didn’t know who had sent it to her, and she had no intention of testing that claim by stepping through anything. She only wanted to find the place, prove to herself she could find it again, and leave before the park gates were locked. She passed between the stones. The warmth came at once: a small, steady pressure against her sternum. “Right,” she said. The word went nowhere. Beyond the boundary, the night was oddly still. Wildflowers covered the clearing, pale blue and yellow and white, bright enough to see without the torch. An oak stood at its centre. The grass beneath it was silvered with dew. Rory turned off her torch to save the battery. For a moment she could hear the ordinary night behind her: a car on the road, a dog barking somewhere far off. Then those sounds stopped. She waited for the car to come back into earshot. A spoon struck the rim of a glass. She looked toward the oak. Nothing moved under it. The sound had been small and clear, the sort of noise she heard from the kitchen at the Golden Empress when somebody stirred tea in a hurry. She listened. A second clink came from farther to her left. “Bird,” she said, though she had no idea what bird would make it. She took out her phone and opened a note. Warm at boundary. Sound inside clearing. No wind. Her thumb hovered over the screen. The wildflowers nearest her leaned toward the centre of the grove, their narrow stems all bent at the same angle. The leaves above them did not move. She added that, too. Rory walked a few paces into the clearing. The grass muffled her shoes. Ahead, a patch of flowers lifted and settled, as if a small animal had passed through them. She trained the torch on it. Nothing was there. A fox, perhaps. She’d seen one on the path near the park gate. The thought helped until another patch moved near the oak, then one behind her. She swung the light back. The flowers stood still. She put a hand over the pendant. Its deep crimson stone, no bigger than her thumbnail, glowed faintly between her fingers. It was warmer now. Not hot enough to burn, but warm in the way a mug stayed warm long after the tea had gone. She had her answer. She turned for the stones. They were farther away than she expected. She could see the two uprights she’d entered between. She could also see the path running to them, a dark line through the flowers. She followed it, looking up every few steps to keep them in sight. After perhaps thirty paces, she stopped. The stones were still the same distance away. Rory looked down. Dew had darkened the toes of her shoes. In the path behind her, two lines of crushed grass ran back toward the centre of the clearing. She had been walking. She was sure of that much. A sound came from the oak: two quick knocks and a third after a pause. She held still. At Silas’ bar, someone used that rhythm when they wanted her to let them into the upstairs flat. She caught herself counting the seconds before the knocks would come again. They didn’t. Rory stepped off the path. The flowers brushed her jeans. She set her eyes on the left-hand stone and walked toward it. This time she counted her steps aloud, keeping her voice low. At twelve she passed a spray of white flowers. At twenty she reached a bare patch of earth the size of a dinner plate. At thirty, she came to the same white flowers. She stopped counting. The bare patch lay ahead of her. She crouched and pressed her palm into it, leaving a print in the damp soil. Then she stood without looking away from the mark and took one step toward the stones. Her handprint was behind her. “All right,” she said, though she was far from all right. She checked the phone. Eleven forty-four. She looked at the note she’d made; the words were still there. Nearly a minute had passed since she crossed the boundary. She could feel the ache in her calves from walking much longer. From the edge of the clearing came the brief scrape of a shoe through gravel. Rory turned sharply. The stones stood empty. Her own shoes made almost no sound on the grass. She lifted one foot and scraped it deliberately through a patch of bare soil. The noise was dull and soft. Gravel scraped again, close to the stones. She lowered her foot. There might be someone out there. A late walker, or a park keeper who’d seen her torch. She opened her mouth to call out. Something beneath the oak drew a breath. Rory shut her mouth. The breath was deep and slow, as if whoever stood there had been holding it for a long time. She aimed the torch at the trunk. Its roots humped through the grass. She swept the beam around it and found nothing. When she turned back, her handprint was at her feet. Her fingers had left clear grooves in the soil. Just beyond them was another print, close enough that the tips of its fingers touched hers. It had the same spread of fingers, the same slight bend to the little finger. Rory stared at it until the light shook. Then she raised the torch and checked the clearing. No one stood among the flowers. She had heard no one approach. The knocks sounded again, this time from the stones. Two quick, one after a pause. Her pulse kicked. She backed away from the prints, trying to keep the oak and the boundary in view at once. The pendant pressed hot against her skin. She pulled it out by its chain. Its red glow had grown brighter, but she could still hold it. Near a portal. That was all she knew. She’d treated the heat as something to follow on the way in. If the place pulling her toward the oak was what made it warm, she needed to go the other way. She stretched out her hand, letting the pendant hang from the chain. It gave a gentle swing toward the oak. Rory turned her wrist. The stone swung again. On the third swing she stepped sideways, toward the nearest edge of the clearing. The warmth eased. She took another step. The chain hung straight. A third, and the stone cooled enough that she felt the difference through her fingertips. The standing stones were to her right. To reach them she would have to cross the strip of grass where she’d found her handprint. Rory kept moving sideways instead, skirting the clearing’s edge. Trees crowded together here. Their branches met overhead, shutting out most of the sky. The spoon struck glass again. This time it sounded directly behind her. Rory kept walking. A few steps later came the scrape of gravel, following at the same pace. She sped up; it sped up. She stopped. The scrape finished half a beat after she did. She looked back before she could stop herself. There were no prints among the flowers. The oak stood dark at the centre. For one instant, the dark beneath its lowest branch seemed crowded, as though someone had stepped close to the trunk and was hiding against it. Her torch found only bark. The pendant had cooled almost completely. Ahead, between two trees, she saw a pair of stones. They were not the ones she had entered through; one leaned inward, and the other had a crack down its middle. Beyond them was a stretch of gravel path and the dim orange glow of a lamp. Rory went toward them. The gravel scraped behind her, quickening. She broke into a run and crossed between the stones hard enough to catch her shoulder on the cracked one. A car passed on the road. She heard its tyres on the tarmac, then the engine fading into the distance. Wind moved through the leaves. Somewhere nearby, an animal rustled in the undergrowth. Rory bent with her hands on her knees and waited until she could breathe without gasping. The pendant lay cold against her chest. On her phone, the time was eleven forty-five. She turned to look back. Between the stones, the clearing was visible: moonlit grass, wildflowers, the oak at its centre. She could still see the bare patch of soil. From here, the two handprints looked no bigger than fallen leaves. Rory put her phone away and started down the gravel path. Her shoes made a sharp crunch with every step. She listened to the sound, grateful for it, until she stopped to check which way the park gate lay. One last scrape came from the gravel behind her. Then the path was quiet.
