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 Fae Grove was eerie at night. Rory shivered as she stepped between the ancient oaks, the gnarled trunks casting long shadows across the clearing. The air was heavy with the scent of wildflowers, the blooms gleaming faintly in the moonlight. She had come here for a reason, though she wasn't certain why. A voice had whispered in the back of her mind, a pull she couldn't ignore. Something about the Heartstone pendant resting against her chest, its crimson depths pulsing with an otherworldly warmth. The boundary stones loomed ahead, their rough-hewn surfaces etched with symbols Rory couldn't decipher. She ran her fingers over the carvings, a tingling sensation running through her fingertips. A faint humming filled the air, and for a moment, she thought she glimpsed a shimmering figure beyond the stones. But when she blinked, it was gone. Rory frowned, her gaze sweeping the grove. The shadows seemed to shift and sway, as if some unseen force stirred the darkness. She strained her ears, but there was only silence, save for the distant hoot of an owl and the rustling of leaves in the breeze. Steeling herself, Rory stepped through the boundary stones. The air seemed to thicken around her, and a prickle of unease crawled up her spine. She paused, listening intently, but heard nothing except the pounding of her own heart. Onward she went, shoes crunching on the carpet of fallen leaves. The canopy of trees overhead blocked out the moon, casting the clearing in a deep, impenetrable gloom. Rory slowed her steps, one hand clutching the Heartstone pendant, the other tracing the contours of the standing stones as she moved deeper into the grove. A faint sound reached her ears, like a whisper just on the edge of hearing. Rory froze, her breath catching in her throat. She strained to listen, but the sound had faded, swallowed by the silence. Slowly, she turned, her gaze sweeping the area behind her. There — a flicker of movement in the shadows. Rory's heart pounded as she stared, willing her eyes to adjust to the darkness. She took a step backward, the rough stone pressing into her palm. The pendant felt warm against her skin, its glow intensifying. A chill swept over her, and Rory shuddered. She couldn't shake the feeling that she was being watched, that something was out there in the darkness, studying her. Swallowing hard, she turned and hurried forward, the leaves crunching beneath her feet. The grove seemed to close in around her, the trees looming ever higher. Rory's breathing grew ragged, her pulse pounding in her ears. She glanced over her shoulder, but the darkness was impenetrable. An owl hooted in the distance, the sound echoing through the clearing. Rory froze, her gaze fixed on a spot just beyond the boundary stones. There, in the shadows, she glimpsed a shape, a figure that seemed to shift and blur. Her heart hammered in her chest as she stared, transfixed. She blinked, and the figure was gone. Rory turned and ran, her legs pumping as she raced through the grove. The shadows seemed to reach for her, grasping and clawing. The pendant grew hot against her skin, its glow flaring to life. Rory clutched it tightly, its warmth a reassuring anchor in the darkness. She burst through the boundary stones, the grove vanishing behind her. Rory stumbled, her breath coming in ragged gasps. She whirled, half-expecting to see the figure lurking at the edge of the clearing. But the grove was silent, the shadows still. Rory stood there for a long moment, her gaze scanning the area. The pendant's glow had faded, leaving her in near-darkness. Slowly, she turned and made her way back towards the path, her steps quickening with each passing moment. As she walked, Rory couldn't shake the feeling that she was being followed. The hairs on the back of her neck prickled, and she fought the urge to look over her shoulder. The grove had been unnerving, but this was different — a tangible sense of danger that sent shivers down her spine. Rory emerged from the trees, the familiar sounds of the park greeting her. She paused, her gaze sweeping the area. Nothing seemed out of the ordinary, and yet she couldn't shake the unease that had settled over her. With a heavy sigh, Rory continued on, her steps quickening as she made her way towards the exit. The pendant felt cool against her skin, its earlier warmth faded. She couldn't help but glance down at it, the crimson depths staring back at her like an unblinking eye. As Rory stepped out of the park and onto the street, she couldn't help but feel a lingering sense of unease. The grove had unsettled her, and she couldn't shake the feeling that she had been watched — that something had been following her, lurking just out of sight. She shivered, pulling her jacket tighter around herself. The Heartstone pendant felt heavy against her chest, a constant reminder of the strange power that had drawn her to the grove. Rory couldn't help but wonder what else might be out there, waiting in the shadows.
