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.

The message had arrived at 11:17, while Rory was wiping rain from the delivery box outside the Golden Empress. You want to know who gave you the pendant? Richmond Park. The stones at the north end. Come alone. No name. No explanation. Just a pin dropped on a map and a photograph of the Heartstone, its deep-crimson face caught in a wash of pale light. She had stared at the picture until the restaurant door swung open behind her and Yu-Fei asked if she planned to spend the night in the rain. Then she had put the phone away, finished her shift, and told herself she was only going to look. Now she stood beneath the trees with the park’s dark spread at her back and the standing stones ahead. The pendant rested against her sternum. Its silver chain was cold. The gem gave off a faint inner glow, barely visible through the open collar of her coat. Rory pressed it between finger and thumb. “Cute,” she whispered. The word sounded too small. It disappeared among the trees without an echo. She checked her phone. 12:06. No signal. The map showed a blank green square, her blue location marker sitting in the middle of it. She had followed a narrow deer path from the road, counting turns, keeping the pale spill of the streetlights in view until the trees had swallowed them. The message pin had led her to the stones. She was certain of that. The stones stood in a rough circle around a clearing. Oak, perhaps, though the moonlight made them look like old bone. Moss furred their sides. One leaned inward, another had split down the middle, and a third was almost hidden by brambles. Beyond them lay grass bright with wildflowers. In December. Rory looked from the flowers to the hard black branches above them. White star-shaped blooms clustered in the grass, their petals open to the night. A few yellow heads nodded among them. None were wilted or bent beneath frost. The air inside the circle felt warmer than outside it, soft against her cheeks and carrying a sweet, heavy smell she couldn’t place. She took one step between the stones. The pendant warmed. Rory stopped. The change was slight at first: a little heat against her fingertips, like the gem had been lying in sunlight. Then it pulsed once, faintly, and the glow deepened to a red that seemed to live beneath the stone’s surface. She let go. “You want to know who gave you the pendant?” The message returned to her, flat and ordinary in her mind. A stranger had taken a photograph of a thing she wore beneath her clothes. That was bad enough. The clearing was worse. Rory turned back toward the path. From here, she should have been able to see the gap between the trees where she’d come in. Instead, she saw more trees, crowding close together. The moon hung over the clearing behind her, bright and swollen. It ought to have lit the park beyond the stones. It did not. She took her phone out again. No signal. The time read 12:06. Still. “Fine,” she said. “One minute.” She walked the circle, keeping the stones on her left. Her boots whispered through the grass. The flowers brushed her ankles, their petals cool and damp. At the far side of the clearing, a small wooden box sat on the ground beside the largest stone. It was dark with age and just big enough to hold a ring. Rory crouched. The box had no lock. A strip of red thread was wound around it, three times. She didn’t touch it. Behind her, somewhere among the stones, something clicked. Rory came upright fast. Her shoulder struck the standing stone. Pain flashed down her arm. The clearing was empty. Flowers, grass, ancient rocks. She listened, holding still. A second click came from the woods beyond the stones. Then a third, slower than the others. The sound of a shoe heel striking pavement. She turned toward it. A branch shifted at the tree line. Not snapped. Shifted, with the careful ease of something leaning around a corner. Rory’s hand went to the pocket where she kept her keys. She wrapped them between her fingers, teeth out. The gesture was ridiculous, but it gave her something solid to hold. “Hello?” No answer. A soft rustle came from behind her. Rory spun around. The box sat beside the stone. The red thread was unchanged. She backed toward the center of the clearing. Her eyes moved over the black gaps between the stones, trying to catch a figure, a face, any shape that didn’t belong. At the edge of her sight, something tall moved between two trunks. When she looked directly, there was nothing. The pendant warmed again. This time the pulse came quicker. The silver chain lay hot against her skin. Rory reached for the clasp. Her fingers were clumsy from the cold—or from the heat. The clasp caught in her hair. She tugged, and the pendant slid free into her palm, its glow painting her fingertips red. The clearing had gone quiet. Not ordinary quiet. The park had been full of small sounds when she crossed it: wind in the trees, a distant road, an owl calling once and then again. Now there was only the faint brush of the flowers against one another. Even that stopped when she held her breath. She heard someone inhale. Rory’s gaze fixed on the largest stone. Its mossy face shone damp in the moonlight. There was a shallow hollow near the top, shaped almost like a handprint. Another inhale. Nearer. She backed toward the stones. One step, then another. The flowers parted around her boots and sprang upright behind them. The old message on her phone felt suddenly less like bait and more like a warning she had failed to understand. She needed to leave. Now. Rory aimed for the gap between the stones where she’d entered. The path should have been directly beyond it. She could see the first black trunks, the low bracken, the slope of the ground. Then a sound came from the woods: her phone ringing. She flinched. The phone was in her coat pocket. It rang again, bright and familiar, the ringtone she’d set for Eva. Rory didn’t move. The phone rang a third time. She took it out. The screen lit her face blue. No signal. No incoming call. The time still read 12:06. From the trees, her ringtone played again. She shoved the phone into her pocket and started toward the gap. Halfway there, she heard her own voice from behind the stones. “Hello?” It had the same pitch, the same little upward lift at the end. The same breathless uncertainty. Rory stopped. The voice came again, from somewhere to her right. “Hello?” A laugh followed it. Not loud. Not quite a laugh, either. More like the sound her throat might make if she tried to cough while smiling. Rory’s feet refused to move. Her heart hammered once, twice, then settled into a hard, steady beat she could feel in her teeth. She could think. She was good at thinking. The sound was a trick. A person could be out there with a recording. Someone had sent her here. Someone knew about the pendant. She looked down at the gem in her hand. Its crimson light had brightened enough to show the crescent scar on her left wrist. The stone pulsed again, hot as a coal. The air behind her changed. A pressure settled between her shoulder blades, as if someone had stepped close without making a sound. Rory ran. She struck the gap between the stones at a sprint, one arm raised to protect her face. The nearest oak brushed her coat. She expected the path, the trees, the dark slope down to the road. The clearing opened around her again. She stumbled through the grass and caught herself on the leaning stone. The wooden box sat beside it. The red thread was gone. She stared at the empty ground where the thread had been. A whisper rose behind her, close enough to stir the hair at her nape. “Come alone.” It was the voice from the message. Or a voice trying to be. Rory spun. The nearest stone stood bare and dark. At its base, among the white flowers, the red thread lay in a neat coil. Something moved beyond the circle. A shape between the trunks, too narrow to be a person, too tall to be anything that could have crouched there. Rory saw the pale oval of a face—or the suggestion of one—tilted toward her. She could not make out eyes. The pendant burned in her palm. She dropped it with a cry. It struck the grass without sound. The glow remained, shining up through the white flowers. The thing at the tree line leaned forward. Rory stepped back. The stone met her spine. For a moment, nothing happened. The figure held still. The grove held still around it. Then, from somewhere far beyond the trees, the owl called once. The figure turned its blank face toward the sound. Rory didn’t wait to see what it would do next. She snatched the pendant from the grass, though it seared her fingers, and ducked between the nearest stones. She ran without looking behind her, pushing through bracken and low branches, following the slope underfoot rather than trusting the path. A twig caught in her hair. The cold night air struck her lungs. She ran until the trees thinned and the road appeared ahead, silvered by streetlights. A bus hissed past, its windows bright and full of people. Rory stumbled onto the verge. Her phone buzzed in her pocket. One bar of signal. The time read 12:08. Behind her, the woods were ordinary: trunks, shadows, the last dark reaches of Richmond Park. No clearing. No flowers. No stones. She opened her hand. The pendant sat against her palm, dull red and cold. On her screen, a new message waited. Thank you for coming. Rory looked up at the trees. Somewhere inside them, in a voice she recognized as her own, something began to laugh.
