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 key was cold in Rory’s hand, the iron biting against her palm as she pushed through the gate into Richmond Park. The lock had been new—too new for a park that had stood for centuries—and it clicked open with a sharp, final sound that echoed through the silence. She shouldn’t have been here. The park closed at dusk, and the November night had long since swallowed the last of the light. But Eva’s message had been urgent, cryptic: *Come to the grove. Alone. You’ll understand when you see it.* Rory hadn’t understood. She still didn’t. But the pendant beneath her shirt had pulsed once, a lazy heartbeat of warmth against her sternum, and that had been enough to make her grab a jacket and go. The path was darker than she remembered. The streetlamps of Richmond stopped at the gate, and beyond them the trees swallowed the moonlight. Her trainers crunched on gravel, then sank into damp earth as she left the main trail and cut across the grass toward the old oaks. She knew the way. She’d come here with Eva a dozen times over the past year, sat on the mossy stones and passed a bottle of cheap wine between them while the city hummed in the distance. It had always felt safe. A secret place, not a dangerous one. But tonight the air was wrong. It pressed against her face, damp and still, and the cold had teeth. She pulled her jacket tighter and kept moving. The first standing stone emerged from the dark like a tooth. Granite, crusted with lichen, taller than a man. She passed it and felt the pendant flicker—a brief warmth, then nothing. The second stone stood twenty paces beyond, and between them the grove opened up: a circle of grass, flat and unnaturally even, ringed by a half-dozen more stones. The wildflowers that should have been dead by now bloomed at her feet, white and purple petals catching what little light there was. They swayed in a wind that she couldn’t feel. Rory stopped at the center of the circle. The pendant was still now, cold against her skin. She pulled it out and looked at the deep crimson gem, the size of her thumbnail. It glowed faintly, a dull red ember that flickered like a dying candle. She’d never seen it do that before. It was supposed to warm near Hel portals, but this wasn’t a Hel portal. This was a patch of grass in Richmond. “Eva?” she called. Her voice came out flat, swallowed by the heavy air. No echo. No answer. She waited. The wind moved through the trees, but it made no sound—no rustle of leaves, no creak of branches. The silence was a wall, and her voice had failed to breach it. The pendant flickered again, brighter this time, and she felt a low thrum in the ground beneath her feet. Something was wrong. She turned slowly, scanning the circle. The stones stood in their ancient ring, stark against the black of the trees. Nothing moved. But she felt it—a presence, pressing at the edge of her awareness. Not a noise. Not a shape. Just the certainty that she was no longer alone. Her breath fogged in the cold air, and she watched the cloud dissipate faster than it should have, as if something had drawn it away. The pendant pulsed once, hard, and a wave of warmth spread from her chest to her fingers. It felt almost protective, but it also felt like a warning. *You’ll understand when you see it.* Eva’s words replayed in her mind, and she realized she didn’t know what she’d been expecting. A note, maybe. A sign. Something human and explainable. But the grove felt anything but human now. It felt alive, and it was watching her. She took a step backward, toward the gap between the first and second stones. Her heel came down on a flower, and the stem snapped with a sound too loud for a simple plant—a wet crack that seemed to linger in the air. She stopped. The pendant went dark, cold as a stone. The silence returned, but it was different now. Thicker. Like something was holding its breath. Rory’s scarred wrist ached, a phantom pain from a fall she’d taken at nine years old. She rubbed it absently and took another step back. The pendant stayed cold. The presence she’d felt—it was still there, but it had shifted. It was no longer watching. It was moving. She heard it then. A whisper, but not words. A rustle of fabric, or skin, against stone. It came from behind the third standing stone, where the shadows pooled thickest. She couldn’t see anything, but the sound was precise, deliberate—a footstep, then another, circling the edge of the grove. Rory’s throat tightened. She forced herself to breathe, to think. *You’re a rational person. This is a park. There are deer, foxes, badgers. The wind plays tricks.* But the wind was still dead, and the footsteps didn’t stop. They moved counterclockwise, keeping to the shadows, and she tracked them with her eyes until they stopped at the stone directly opposite her. The silence stretched. The pendant remained cold. Then the footsteps began again—coming toward her. She ran. Her legs moved before her mind caught up, carrying her across the grass toward the gap in the stones. She didn’t look back. She didn’t want to see what might be following. The gap was five paces away, then three, then one—and she burst through it onto the path, stumbling as her foot caught on a root. She caught herself on a tree trunk, bark scraping her palm, and kept going. The path unspooled ahead of her, faintly lit by the distant glow of the city. She followed it without thought, her breath ragged, the pendant bouncing against her chest. It stayed cold. She reached the gate and slammed it shut behind her, fumbling with the lock. Her hands shook, but she managed to click it closed. Only then did she stop and look back. The park was still. The trees stood dark and silent. There was no movement, no sound. The grove was hidden beyond the oaks, and from here it looked like nothing more than a patch of woods. The pendant warmed again, a soft, steady pulse. Not a warning this time. Almost an approval. Rory leaned against the gate and pressed a hand to her chest, feeling the gem’s warmth through her shirt. Her heart hammered against her ribs, and her breath came in white clouds that vanished into the night. She waited for ten minutes, then twenty. Nothing emerged from the trees. Eventually, she turned and walked home. She didn’t look back again. But she felt the weight of the grove’s attention on her shoulders all the way down the street, and she knew, with a certainty that sat cold in her stomach, that she hadn’t escaped. She’d only been allowed to leave.
