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 because the pendant was warm. Not pleasantly warm. Not the faint body-heat it sometimes held beneath her shirt, but a steady, insistent heat that had woken her at half past midnight. She had sat up in the dark with one hand closed around the crimson stone, listening to the flat above Silas’ bar settle and creak around her. The pendant had pulsed against her palm, once, then again. She could have put it away. She could have told herself it was a trick of nerves, or the radiator, or the strange things that happened when she was tired. Instead, she had followed it. Now Richmond Park spread black around her, its familiar paths stripped of familiarity beneath the trees. She stood before a ring of ancient oaks, their trunks thick as pillars, their bare branches netted against a starless sky. Beyond them lay a clearing she had never noticed in all the times she’d walked these grounds by daylight. The pendant burned through her shirt. Rory pulled it free. The silver chain slipped over her knuckles; the thumbnail-sized stone rested against her palm, deep crimson at its center. A faint light seemed to breathe inside it. She turned toward the oaks. The glow strengthened. “That’s helpful,” she whispered. Her phone showed no signal. The map app had frozen on a blank square, though she’d downloaded the area earlier. She tapped the screen anyway, once, twice. The white glow caught her reflection: bright eyes, black hair tucked behind one ear, a little too pale. Her left wrist showed its small crescent scar where her sleeve had ridden up. She was alone. She had checked. A bicycle path ran behind her, empty in both directions. No footsteps, no rustle of another person moving through the park. The city was close enough that she ought to hear it—the low murmur of traffic, a siren, the distant grumble of a bus—but the night had swallowed everything. Even the wind had stopped. Rory put the phone away. She had come to find out why the pendant was reacting. That was all. Look at the clearing, take a few pictures, leave. If she found nothing, she could go home and blame the whole thing on nerves. The oaks made a boundary, their roots humped above the earth. She stepped between two trunks. A sound came from behind her. Not a voice. A small, neat click, like a fingernail tapped against glass. Rory turned. The path lay empty beneath the trees. She waited. The pendant throbbed once against her palm. “Wind,” she said, and heard how thin her voice sounded. There was no wind. The branches remained perfectly still. She crossed into the clearing. Wildflowers covered the ground in a low, pale scatter. They should have been sleeping under the cold season’s dark, but their heads nodded in the faint light from Rory’s phone. The grass between them was silvered with dew. At the clearing’s center, a flat stone stood among the flowers, its surface slick and black. The air felt different here. Not colder, exactly, but close—like the inside of a crowded room after everyone had stopped talking. Rory took a picture. The flash went off. For an instant the clearing leapt into sharp detail: the flowers, the central stone, the line of oaks behind her. And a figure standing among the trees. The flash died. The figure was gone. Her thumb hovered over the phone. She opened the photograph. There was no one in it. Only trunks and shadow. Rory turned slowly, keeping the phone raised. Her eyes searched the places between the trees, the spaces where darkness thickened. Nothing moved. She told herself the flash had made a shape of the branches. The mind supplied faces where there were none; it was a trick as ordinary as seeing a rabbit in a cloud. At the edge of the clearing, something shifted. Not a shape. A difference in the dark. A patch of it drawing back behind a trunk. Rory’s hand tightened around the phone. “Is someone there?” The words fell into the stillness. No answer came. She took a step toward the trees, then stopped. She was not going to follow a shadow into the woods. She had enough sense for that. The pendant pulsed again. Its warmth had spread across her palm and into her fingers. The stone’s inner glow was brighter now, a red pinprick that seemed to deepen when she faced the flat stone in the clearing. A faint sound drifted from the far side of it. Rory listened. A woman humming. The tune came in short, uncertain phrases, the way someone might hum to herself while looking for something. Rory could not place it. The voice—or whatever made the sound—was too soft to be coming from beyond the trees. It seemed to rise from the flowers, from the ground beneath them. Her mouth went dry. “Hello?” she called. The humming stopped. She backed toward the oaks, eyes fixed on the stone. The edge of her heel caught on a root. She stumbled, and in the same instant, something brushed the back of her coat. Rory spun. The trees stood where they had been. The clearing was empty. Her pulse beat in her throat. She yanked her coat forward and checked the fabric, though she knew there’d be nothing to find. Her fingers were clumsy on the buttons. The phone vibrated in her other hand. She nearly dropped it. The screen lit with a notification, then went dark before she could read it. No signal. No message. The vibration had come from inside the phone, a glitch or a dying battery. She swallowed and looked at the time. 12:46. She had entered the park at 12:31. The walk from the gate had taken less than ten minutes. She should have been back at the road already. A minute later the time changed to 12:45. Rory stared at the screen. The digits held, then flickered. 12:46. 12:45. 12:46. She shoved the phone into her pocket. “Go,” she said. The path between the oaks was where she remembered it. She could see the pale strip of gravel beyond the trunks. Her feet carried her toward it. She did not run. Running would turn this into panic, and panic would make every shadow into a threat. She had a plan: get out, find a lit street, call Eva. In the morning, she would decide what the pendant meant. She reached the boundary. The path beyond the trees was gone. There was only more clearing, dark grass, and another ring of oak trunks standing a short distance away. Rory stopped so abruptly her shoulder struck a tree. Bark scraped her coat. She looked behind her. The flat stone remained at the center of the clearing. The flowers still nodded, though the air was still. “No,” she said. She walked toward the new ring. The pendant’s light fluttered in her hand. As she crossed between the trees, she heard a soft footfall behind her. Then another. Rory did not look back. She kept her eyes on the dark opening ahead, counting her steps as she went. One, two, three. The footfalls followed, spaced to match hers. When she stopped, they stopped. At the next boundary, the path was gone again. She turned at last. A figure stood in the clearing behind her. It was a woman, or it wore the shape of one. She stood beside the black stone with her head tilted, hands folded loosely at her waist. Rory could not make out her face. The wildflowers hid her feet. She wore something pale that hung straight from her shoulders, untouched by any wind. Rory’s tongue stuck to the roof of her mouth. The figure raised one hand and pointed. Not at Rory. At the pendant. The stone flared hot enough to hurt. Rory jerked, and it slipped from her fingers. The chain snapped taut against her neck. For one wild moment, she thought the pendant would burn through her shirt, through her skin. The figure lowered its hand. Rory grabbed the chain and pulled it over her head. The silver links snagged in her hair. She tore them free and dropped the pendant. It struck the earth without a sound. The figure was gone. She backed away, keeping her eyes on the place where it had stood. Her heel touched the root of an oak. She turned and found herself facing the first ring of trees again—the one she had entered through. Beyond it, the familiar park path curved under the darkness. Rory went. She did not run until she saw the gravel. Then she ran hard, branches scratching at her sleeves, lungs tearing at the cold air. Behind her, the humming began again. It was closer now, sweet and patient, threading through the trees. She reached the path and kept running. At the gate, her phone found a signal. The screen said 12:52. She had been gone twenty-one minutes. Rory stopped under the yellow spill of a streetlamp and pressed both hands to her knees. Her heart hammered. The pendant lay heavy against her chest. She straightened slowly. The silver chain was still around her neck. The crimson stone rested over her shirt, warm as a living thing. In its center, a faint light pulsed once. From somewhere behind the gate, a woman began to hum.
