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.

Rory had come to the grove because the pendant was warm. Not warm from her skin. Warm in her palm, through her coat pocket, as if someone had left it on a radiator. She had been halfway across Richmond Park when the crimson stone began to pulse against her fingers. Once. Then again. A small, steady throb that didn’t match her heartbeat. She had followed it past the darkened paths and the sleeping deer, toward a stand of ancient oaks she knew she’d never seen before. The trees crowded together, their branches knitting a roof against the cloudy sky. Between their trunks, the standing stones marked a boundary—or the suggestion of one. Their black surfaces glistened with rain, though Rory hadn’t felt a drop. She stopped just short of them. The pendant cooled in her hand. “Right,” she said softly. “That’s encouraging.” Her voice went no farther than the stones. Beyond them lay a clearing washed in the thin silver light of a moon she couldn’t see. Wildflowers crowded the grass, bright and fresh as spring, though the air had the bite of winter. Their pale faces turned toward her. Rory put the pendant back beneath her shirt. The silver chain lay cold against her throat. She had come to find out why it had started reacting, and to prove to herself that whatever had happened at the bar last week had been a trick of shadow and exhaustion. The second reason was the one she wouldn’t say aloud. She took out her phone. No signal. The time on the screen read 12:14. She looked up, then back down. Still 12:14. A tightness gathered behind her ribs. She pushed the phone into her pocket and stepped between the stones. The air changed on the other side. Not colder, exactly. Thinner. Her ears popped. The woods behind her seemed to draw away, the path dimming between the trunks until it was difficult to see where she’d come from. The clearing opened around her. Grass brushed her ankles. The wildflowers gave off a faint, sweet smell, like something left too long in a vase. Rory turned in a slow circle. No one. No lights from the park. No distant road noise. The grove was a pocket of quiet pressed into the night, too clean and complete to be natural. She could hear the rasp of her own coat sleeve as she moved. Her breath. The faint click of the pendant against its chain. Then, from somewhere ahead, a child laughed. Rory stopped. The sound had been brief. High and delighted. It came from the dark edge of the clearing, beyond a tangle of hazel. She waited for a second laugh, a whisper, the thump of feet through grass. Nothing. “Hello?” The word fell flat. No echo. No answer. She took a step toward the hazel. The pendant warmed again, its pulse slow and deliberate through the fabric of her shirt. She didn’t want to touch it. She did anyway. The stone was hot now. Not enough to burn, but enough to make her pull her hand away. Its faint glow showed through the cloth, a red spot beneath her palm. Rory swallowed. She had heard about this place from Silas, though he’d called it Isolde’s grove and refused to say how he knew it existed. A hidden clearing. A door in the park. A place where time could slip sideways. He’d said it like a warning and then changed the subject. She had assumed it was one more London story—one more strange thing people told after closing, when the lights were low and the whiskey had been generous. A twig snapped behind her. Rory spun. The stones stood in a dark line at the edge of the clearing. Beyond them, the trees pressed close. She couldn’t make out the gap where she’d entered. She walked back a few paces, eyes on the stones. The flowers in her path bent away from her boots. One by one, their white heads turned toward the centre of the grove. A soft shuffling came from the trees. She froze. It moved from left to right, too steady to be a squirrel, too quiet to be a person walking through brush. The sound stopped when she stopped listening for it. Rory reached for the small folding knife in her pocket. The handle was slick under her palm. She didn’t open it. A blade would be a gesture, not protection. The pendant gave another warm pulse. Somewhere behind the hazel, a woman said, “You’re late.” Rory’s skin tightened along her arms. The voice sounded close. Calm. Familiar enough to make her think of Eva, though it wasn’t Eva’s voice. It had the same easy certainty, the same assumption that Rory would answer. “Who’s there?” A pause. “You know why you came.” “I do?” The hazel branches stirred though the air was still. Rory watched them, searching for a face, a pale hand, some ordinary explanation she could hold on to. The branches settled. From the other side of the clearing came a second sound: a low, wet cough. She glanced over her shoulder. Something stood between the oaks. At first she thought it was a person in a long coat, turned sideways. Then she noticed how tall it was. Its head rose above the lower branches, tilted at an angle that made her neck ache in sympathy. It didn’t move. It didn’t need to. Rory’s fingers closed around the knife. “Hey.” The shape leaned slightly forward. She backed away, careful not to turn her back on it. The standing stones were behind her. If she could get through them, if the way out was still there, then she could— A laugh sounded at the hazel again. This time it came from just behind her left shoulder. Rory jerked around. Nothing but flowers and shadow. Her pulse began to climb. She forced her breathing to slow, counted it the way she had when Evan had been shouting and she needed to keep her thoughts clear. In. Hold. Out. The shape between the trees was gone. She stared at the place where it had stood. The branches there were bare, black against black. No retreating footsteps. No movement. The pendant glowed brighter. Its heat spread through her shirt and into her skin. Rory yanked the chain over her head. The stone swung from her fingers, crimson and luminous, the size of her thumbnail. Its inner light thickened until the edges of the gem looked wet. The grove answered. Every flower in the clearing bowed at once. Not with the wind. The stems bent toward the pendant. The grass shivered in widening rings, starting at Rory’s boots and moving away from her. From beneath the trees came a sound like someone drawing breath through clenched teeth. She backed toward the stones. A voice spoke from the darkness, close enough that she felt the words against her ear. “Give it back.” Rory whirled. Nothing stood behind her. She slashed the knife through the air anyway, the blade catching a faint red gleam. “Who are you?” The answer came from all around her. “You know.” She did not. She was certain she did not. Yet a pressure formed at the back of her mind, as if a memory were trying to press through a locked door. A flash of a child’s hand. A dark room. A voice saying her name with the tenderness of someone who had no right to know it. She clamped down on the thought. The pendant pulsed hard enough to hurt. She let it drop into her palm, then looked toward the stones. They seemed farther away than before. The clearing stretched between her and the boundary, flowers and grass rippling in the dark. The gap between the stones was there, but the park beyond them had vanished. In its place, she saw another stand of trees, more closely packed, their trunks pale as bone. A thin mist moved between them. Rory stopped. From the trees came the sound of her phone ringing. She reached into her pocket. The screen lit under her fingers. No signal. The time read 12:14. The ringing continued. She pulled the phone out. The display showed Eva’s name. Rory hesitated, then answered. “Eva?” A silence. Then: “Rory, where are you?” Relief loosened something in her chest. “Richmond Park. I’m near the—” “You need to leave.” The voice was not Eva’s. It was a child’s, muffled and thin, as if speaking from beneath water. Rory ended the call. The phone rang again at once. She threw it into the grass. It landed face-up, still glowing. On the screen, the time had changed to 12:15. The flowers began to turn toward it. Rory moved. She ran for the stones, ignoring the tug of grass around her ankles, the branches scraping at her coat where no branches had been. The pendant burned in her fist. The red light flickered between her fingers. The pale trees beyond the boundary leaned inward. She reached the stones and thrust herself through the gap. Cold night air struck her face. Richmond Park lay quiet under a bank of clouds. The path was a few yards away. A line of lamps glimmered beyond the trees. Rory stumbled onto the muddy ground and kept running until she reached the path. She didn’t stop until she saw the first lamp and the dark shapes of deer grazing beneath it. Her hands shook. She opened them. The pendant lay in her palm, dull and cold. Behind her, somewhere deep among the oaks, a child laughed once. Rory turned. The park stood empty. The trees were ordinary trees, their branches swaying in a wind she could feel now against her cheeks. She looked at her phone. The screen was black. When she pressed the button, it lit up. 12:16. She stood very still, listening to the city beyond the park, to the faint wash of traffic and the distant bark of a dog. Everything sounded normal. Then, from beneath her coat, the pendant pulsed against her hand. Once. And somewhere in the trees, something answered.
