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 first thing Rory noticed was that the grass was dry. Rain had followed her across Richmond Park, needling through the hood of her jacket and turning the paths to black paste. She had climbed the low rise toward the grove with mud pulling at her boots. Yet beyond the ancient oak standing stones, the ground gave softly beneath her feet, dry as a summer lawn. She stopped between two trunks and looked back. Rain silvered the park on the other side. She could hear it striking leaves, a steady, granular hiss. No drops fell in the grove. “That’s normal,” she said, though she had never known what normal meant here. Her phone read 11:43 p.m. The message that had brought her said only: Come to the grove tonight. Bring the Heartstone. If it gets warm, don’t follow it. It had arrived on her phone without a number. Rory had spent an hour deciding whether that made it more or less likely to be from the stranger who had given her the pendant. In the end, she had come because the warning implied there was something to follow, and she wanted to know what it was before it found her elsewhere. She took the phone out again. No signal. The time still read 11:43. Wildflowers spread under the trees in pale, untidy drifts. Their heads were open despite the hour, white and yellow faces turned toward a sky she couldn’t see through the branches. A faint light lay over them. It was enough to find her way without the torch, but she switched it on anyway. The beam picked out bark, flowers, and a narrow track through the grass. Nothing else. No sign of whoever had sent the message. Rory tucked the phone away and walked toward the middle of the clearing. The pendant rested beneath her jumper, its thumbnail-sized crimson stone cool against her skin. She had expected to feel foolish coming out here alone. Instead she felt the practical annoyance of a delivery address without a doorbell. “If you wanted me here,” she called, “I’m here.” Her voice carried a short distance and stopped. It did not echo. The rain went on beyond the standing stones. Something clicked behind her. She turned. Her torch found an oak trunk, split low down where two roots rose from the ground. A beetle might have snapped its wings shut. A branch might have settled. She waited until her arm began to ache, then lowered the beam. A second click came from ahead, near the far edge of the grove. Rory looked between the two places. Neither offered an answer. She started walking again, slower. At the centre stood a circle of bare earth no wider than a table. The flowers ended at its edge. Inside, the soil was dark and finely ridged, as if someone had dragged careful fingers through it. Rory crouched and held the torch close. The ridges ran in narrow curves that met and separated. They were too regular for rain damage, and the rain had not reached this place anyway. She put out a hand, then drew it back. Touching it would tell her very little. A bird called from the trees. Three clear notes, evenly spaced. Rory stood. She knew the call. She had heard it on the climb through the park, from somewhere behind her. Three notes, then a pause, then three more. It had sounded close then too. The bird called again, this time from the standing stones. She swept the torch across the boundary. The wet park beyond it lay empty. On the near side, flowers nodded in the still air. Three notes sounded beside her left ear. Rory flinched and spun. The beam shook over trunks and grass. Nothing stood within ten paces. She held still, embarrassed by the speed of her breathing, and listened. Rain. A little movement high in the branches. Beneath it, a dragging sound, soft and brief, as though a sleeve had brushed a tree. The message had not told her to wait. It had only told her not to follow the pendant if it grew warm. She had come to see whether it would. She slipped her fingers under her collar and touched the stone. Cool. “Fine,” she whispered. She headed back toward the boundary. The grove was not large. From the circle of earth, she could see the gap between the same two oak stones she had entered through. She kept her eyes on it and counted her steps. At thirty-eight, the rain sounded farther away. At fifty, the gap looked no closer. Rory stopped counting. She aimed the torch at the trunk to her right. A long scar in the bark ran from shoulder height almost to the ground, pale against the dark wood. She passed it, taking eight deliberate strides. The scarred trunk stood to her right again. She faced it for a long moment. Then she turned her torch behind her. The circle of bare earth was perhaps twenty paces away. A bad angle, she told herself. There were more trees than she had thought. She could have curved without noticing. She walked straight toward the rain, setting the torch on the gap and refusing to glance aside. Grass swept her boots. The white flowers thinned. The two trunks widened apart as she approached. Three notes sounded ahead of her, just beyond them. Rory stopped at the boundary. Rain fell an arm’s length away. She could smell wet bracken and churned mud. She reached through the gap with her free hand. Cold drops struck her fingers. She laughed once, quietly, at the relief of it. Then something reached back. There was no hand to see. Her fingers met pressure in the rain: five light points touching hers through the falling water. They held for less than a second. Rory yanked her arm back and stumbled into the grove. The wetness ended at her knuckles. Her fingertips were dry. For a while she could not make herself move. The torch lit the empty gap. Rain fell through her beam and burst white against the path beyond. No shape stood there. Her phone vibrated in her pocket. She nearly dropped the torch getting it out. The screen showed 11:43 p.m. There was a new message. You came early. No number. No earlier message in the thread, though she had read it half a dozen times on the way here. Rory typed, Who are you? The reply appeared before she could press send. Turn around. She locked the screen and did not turn. Behind her, someone took a breath. It was small and close, the sort of breath a person drew before speaking. Rory stared into the rain. She could run through the gap. Whatever had touched her might still be out there; whatever had breathed was in here. She preferred the danger she could see, even if seeing it told her nothing. The pendant warmed against her chest. It began as a patch of heat no larger than the stone. Rory caught the chain through her jumper. Silver slid against her neck, and the crimson gem pressed warmly into her palm. Near a Hel portal, she remembered. That was what the stone did. She had no idea how near counted as near. A faint red glow showed between her fingers. The breath came again behind her, unhurried. Rory moved sideways until one of the oak stones stood at her shoulder. If she had to turn, she wanted the trunk between them. She edged around it, lifting the torch. The grove behind her was empty. Flowers filled the clearing. At its centre, the circle of bare earth had changed. The ridges were gone. In their place lay a single narrow depression, the shape and length of a body. Its upper end pointed toward her. She held the beam on it. The edge of the depression crumbled inward. Something beneath the soil shifted. Rory took a step toward the boundary. The pendant grew hotter. Not searing, but insistent. It pulled at the chain as she moved, a slight, unmistakable weight toward the centre of the grove. Don’t follow it. She grabbed the stone through the jumper and pinned it against her ribs. It still tugged. At the edge of her vision, a figure crossed between two trees. Black hair. Dark jacket. Her height. Rory’s torch snapped toward it. The flowers under those trees stood undisturbed. She turned back to the gap. It was gone. The two ancient trunks remained, but another oak stood between them, its roots sunk deep into the dry grass. Its bark was smooth except for a pale mark near the base: a small crescent. Rory touched the scar on her left wrist without meaning to. A voice spoke from the far side of the new tree. “You’re early.” It sounded like her voice after a long walk in cold air. A little rough, the Welsh edges of her vowels more pronounced. Rory said nothing. “Come around,” the voice said. “I can explain.” She looked at the tree’s roots. They were thick with moss. Wildflowers grew in the hollows between them. If the trunk had arrived in the last few seconds, the grove had supplied it with years. Her phone vibrated again. She did not look. The voice sighed. “You’re always like this.” It knew the easy, irritated note she used with herself when she had lost her keys. That was worse than the imitation of her accent. Rory backed away from the tree. She fixed her eyes on the scarred bark to her right and moved toward it. The pendant pulled hard enough to slide from under her jumper. The crimson stone hung in the open, glowing faintly against her jacket. At the bare circle, soil rose along the edges of the depression. She heard it shifting over itself. She did not look down. “Rory,” the voice called. She had been called by her own voice; she had not expected it to use her name. She stopped with one boot at the rim of the disturbed earth. The bird gave its three clear notes from somewhere overhead. After the pause, it tried again. On the third note, the sound broke into a human cough. Rory lowered her torch and saw a second set of footprints in the grass beside hers. They were not impressions in the soil. The blades simply lay flattened, two parallel tracks keeping pace with her. As she watched, the next patch of grass bent under an unseen foot. One step. Then another. The tracks stopped an arm’s length away. Rory held her breath. She thought of the wet fingers at the boundary, the voice behind the tree, the body-shaped hollow waiting at her feet. All of them had wanted a response. Perhaps they needed one. She switched off the torch. Darkness settled in layers. The flowers kept their weak shine. Beyond them, the trunks became thicker black shapes against the sky. The pendant’s crimson glow lit the backs of her fingers. Beside her, grass bent again. Rory moved at the same time, not toward the place where the rain had been, but toward its sound. She followed the hiss between the trees, quick and straight, with her free hand out to keep from striking a trunk. The pendant dragged backward. She clenched it so tightly the edge bit into her palm. A voice behind her said, “Wait.” Hers. Breathless now. She kept going. Rain appeared ahead in a narrow strip, silver in the dark. Rory pushed through a gap between two oaks and out onto the muddy path. Water struck her face and soaked her hair at once. Her boots skidded. She caught herself against a real tree, its bark slick beneath her hand. For several seconds she listened to the rain, letting it wash over every other sound. Then she checked her phone. 2:17 a.m. She had been inside for minutes, she thought. An hour at most. The grove had never promised to agree. The pendant cooled in her hand. When she opened her fingers, its faint inner glow had gone, leaving the deep crimson stone almost black. Rory turned toward the boundary. Rain fell through the gap between the standing stones. She could see the dry grass beyond, and the flowers, and a narrow track leading into the clearing. No one stood on it. A patch of grass near the centre bent under a foot. Rory stepped back. Another patch bent, closer to the stones. A pause followed. Then three clear notes came from the grove, so soft she might have mistaken them for a bird if she had not heard the breath drawn first. She put the pendant under her jumper and started down the path. She did not run until the rain behind her stopped making any sound.
