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 gate at the north end of Richmond Park stood open, which was the first thing wrong. Not wide—just a hand’s width, enough for a slim body to slip through—but the bolt had been drawn back, and the chain hung loose against the iron like a tongue from a bell. Rory stopped with her phone light aimed at the gap. The beam caught the edge of a notice—PARK CLOSES AT DUSK—and nothing else. No wind. No distant traffic. London had gone mute behind her. She had come because the pendant had not let her sleep. For three nights the Heartstone had pulsed against her sternum, a deep crimson throb she felt through her jumper, and each pulse had pulled her toward the park with a gravity that made her teeth ache. She wasn’t a fool. She’d left a note on the kitchen counter of the flat above Silas’ bar, scrawled quickly before her courage thinned: gone walking, back by one. It was half past eleven now, the roads empty, the city’s usual hum erased by fog that had rolled in off the river. The pendant warmed as she passed through the gate, then cooled so fast it might have been a stone pulled from a stream. Rory pressed a hand over it. The silver chain lay cold at her throat, and the gem—deep crimson, no bigger than her thumbnail—had gone dark. She moved along the gravel path, phone light cutting a narrow cone through the fog. The oaks rose out of the dark like patient giants. Mist pooled around their roots. Her trainers made no sound, and after a dozen steps she realized the gravel had gone soft with moss. She stopped. Behind her, the soft scuff of a footstep. She turned. The path lay empty. The gate was a faint iron line far back, the streetlamp beyond it no longer visible. She held her breath and listened. Nothing. Then, from somewhere to her left, the grass made a sound like a woman turning in her sleep—dry, slow, deliberate—and fell still. “Deer,” she said, too quietly. Her voice did not carry. It dropped into the mist and vanished. Rory forced herself onward. She knew the way. The grove was off the main path, past a lightning-blasted beech, through a fold in the land that hid the standing stones until you were almost on them. In daylight she had found it twice, both times by accident, and both times she had felt the oddest certainty that the place had been waiting for her to leave. But torchlight twisted the landscape. The beech was wrong—its trunk split at a lower point than she remembered, and a dead branch stretched toward the path like an arm. She told herself memory was unreliable in the dark. The pendant had gone warm again, then cold. Not the guide she’d hoped for. It felt less like an invitation now, more like a warning. The standing stones appeared before she expected them. They weren’t stones, exactly, or not only stones—ancient oaks with bark so old it had turned gray and mineral, twisted around slabs of granite that jutted from the earth like teeth. The boundary of the grove. Wildflowers bloomed between the roots, small white stars that should have been dead in late autumn, and their scent hit her in a wave—honeysuckle and rot, sweet enough to turn her stomach. She crossed the boundary, because that was why she had come. She needed to know who had sent her the pendant, and why it had chosen now to wake. She needed to understand the pull. The alternative was going home to a flat above a bar and lying awake with a heartbeat in her chest that was not her own. The wildflower scent grew stronger, then faded to nothing. The mist inside the grove was lower, only ankle-deep, and it moved against the air, slow, against the direction she walked. Rory’s phone flickered. The screen showed 11:47. She looked away. When she looked back, it read 2:13. She thumbed the lock button. The screen went black and would not wake. “Right,” she said. Her voice came out thin. “Time’s broken. Noted.” She turned back toward the path, because the wrongness was no longer subtle. The pendant hung dead against her chest, its inner glow extinguished. She had come for answers, but the grove was not answering. It was waiting. The path was gone. Not hidden. Gone. Where she had entered, a wall of oaks stood shoulder to shoulder, their trunks too close to pass between. The standing stones had moved. She had not heard them move. She had not heard anything at all. Rory stopped turning in a slow circle. She made herself breathe in through the nose, out through the mouth—an old habit from her father’s cross-examination drills. List the facts. One: she was alone. Two: the grove was a pocket between Earth and the Fae realm, and time moved differently here. Three: the Heartstone pulsed near Hel portals, but it was not pulsing now. She was not, her mind repeated, alone. At the edge of her vision, between two oak stones, a shape stood. Tall. Too tall. Narrow in the way a dead tree is narrow, but with a head that tilted at a listening angle. The mist rose around it. When she turned her head directly, the shape was gone. The space between the stones was empty. Rory did not run. Her body wanted to, but she had learned long ago that running from Evan had only fed him. Predators liked the chase. She stood her ground and raised the dead phone, not as a light but as a shape in her hand, something solid to hold. “I know you’re there,” she said. The words fell into the grove and did not echo. The silence after them was absolute, like a held breath. Then the sound came—not a footstep this time, but a long, slow scrape, like antler bone dragging across bark. It came from her left. Then from behind her. Then from directly ahead. Rory’s hand found the pendant and squeezed. The stone was cold and hard, no pulse, no warmth. But under her thumb she felt a single tremor, faint, not its own. A heartbeat. Not hers. The shape was closer now. She had not seen it move. It stood at the edge of the wildflower ring, no longer between the stones but inside the grove, at the very limit of her sight. The mist thickened around its feet. The shape had branches where its arms should have been, or antlers, or both, and the head tilted the other way. She knew then that the grove had not been empty when she entered. It had been full. The things at the edge of her vision had been there all along, still as stone, watching her cross the boundary. She had mistaken them for oaks. Rory forced herself to look away, to find the path, but the landscape shifted again. The standing stones were closer now, the circle smaller. Or she was deeper inside. The wildflowers bloomed under her feet, pale and silent. Her phone had been gone from her hand—she didn’t know when she’d dropped it. “Listen,” she said, to the shape, to the grove, to herself. Her voice cracked at the end. “I’ll leave. I’ll go back through the gate. I won’t come again.” The shape did not answer. The scrape came again, slower, closer, from all around, as if a circle of antlers were being dragged along the inside of the stones. The pendant grew colder until her skin ached. She could feel the cold spreading down her wrist to the small crescent scar, and she clutched the stone harder, willing it to warm, willing it to give her any sign that she was still on the right side of the boundary. The moon came out from behind the clouds, and for one full second she saw the grove clearly: the ring of stones had closed to half its size. The wildflowers were not white. They were pale hands, open, rooted. The shapes between the oaks were not oaks. Then the moon went in again, and the dark came down like a door. Rory stood still in the pocket between Earth and somewhere else. She was not alone. She had never been alone. The thing in the grove had been waiting for someone like her to bring the Heartstone home. She heard it breathe for the first time—a slow, inhaling sound, like bark splitting. It was behind her.
