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.

Aurora Carter stood at the boundary of The Fae Grove, marked by ancient oak standing stones that loomed like silent sentinels under the moon's cold gaze. Her breath came in measured clouds as she stared into the hidden clearing, a different world nestled within Richmond Park. This place had always unnerved her, but tonight, a deeper unease had a hold on her spine, knotting it taut. Time moved strangely here, and she needed to keep her wits about her if she was to achieve what she had come for. The canopy of trees swallowed the pale light, leaving patches of shifting shadow that seemed to dance when she wasn't directly looking at them. The familiar whisper of her name on wind's breath sent a shiver through her. "Rory," it ghosted, pressing against her ears with an intimate menace. She adjusted the Heartstone Pendant around her neck, its faint inner glow barely visible. Its warmth against her skin was a small comfort. The pendant belonged to Dymas, whoever that was, but its value was not lost on her. It had pulsed at the edge of the Grove, a soft heartbeat against her chest, guiding her like a beacon to this moment. She gathered her courage and stepped past the standing stones, entering the realm between realms. The wildflowers bloomed riotously at her feet, their bright colors dulled by the night but still vibrant enough to jar against the muted backdrop of the Grove. As she walked, the sound of her footsteps was swallowed by the soft earth, leaving an eerie silence in its wake. In the distance, she could hear the rustling of leaves, but there was no wind. The initial path, barely visible under the matted undergrowth, broke off into a series of serpentine trails, each promising deeper immersion into the Grove’s secrets. Rory hesitated, scanning for any sign that might distinguish one from the other. There was none. Trusting her gut, she chose the leftmost trail, her hands brushing past fern fronds that seemed to recoil at her touch. Minutes bled into hours—or was it seconds? The disorienting effect of the Grove’s time behavior gnawed at her. Every so often, she caught sight of a movement from the corner of her eye—a brief flicker of something darting between the trees, or was it just her mind’s trickery? The uncertainty of not knowing made her heart pound louder, a rhythmic counterpoint to the pendant's steady pulse. Ahead, a small clearing opened up, the moonlight more discerning here as it painted the ground with silvery brushstrokes. Aurora stepped into the space, feeling abruptly vulnerable as the trees formed a close-rank circle around the clearing, trapping the light in a tight embrace. A sudden snap of a twig behind her made her whirl around, every muscle tightened to snap. "Who's there?" Her own voice startled her, the desperate edge betraying the cold facade she carefully maintained. Only the trees stared back, their boughs waving nonchalantly. She turned back, gripping the pendant tighter. Remember why you're here, Rory, she reminded herself. Her mission was pressing, but the Grove had a way of making priorities diffuse, dissolving the sharpness of intent with trickery. Then she heard it—a muffled giggling, like the suppressed laughter of a child trying not to get caught. "Eva?" she whispered, though it was absurd; her childhood friend was far away, safe. Yet, she followed the sound, weaving through the maze of trunks, each step drawing her deeper into the thick embrace of the ancient forest. More noises followed—a splash of water though she saw no brook, the scuttling of claws on bark, the hum of disembodied whispers—and each pulled at the frayed edges of her courage. Her instincts warred between pressing forward and retreating to the safety of the mundane world beyond the standing stones. Rory came upon another clearing, this one smaller, more intimate. At its center stood a quaint stone well, its rim covered in thick moss. Water from an unknown source trickled into the basin, an oddly soothing sound amidst the chaos. She approached cautiously, peering over the edge. In the still, dark water, her reflection stared back, but not her face as she had last seen it. This Rory was gaunt, haggard, eyes wide and haunted. "You shouldn't be here," the reflection murmur-whispered, lips moving in perfect sync with her unspoken thoughts. "They're watching." A chill coursed through her blood. She stepped back hastily, almost tripping. From within the well, a long, thin arm reached out, rooting her to the spot. The light from her pendant flickered, synchronized with the rapid beats of her heart. "Leave now," the voice from the well commanded, harsher, filled with urgency. "Who are you?" Rory demanded, though her voice was but a rasp. "Guardian," the voice replied, a tone edged with despair. "You were not meant to enter. It attracts them." "Who are they?" Rory asked, though deep down, she wasn't certain she wanted the answer. Before the Guardian could reply, the clearing darkened, as if the night itself thickened into a tangible presence. The hairs on the back of her neck bristled, every instinct urging her to flee. She turned to face the encroaching darkness, her fists tight against the pendant. There, at the edge of the clearing, stood a figure. It was tall, impossibly thin, its limbs elongated in ways no human's should be able to bend. Its eyes—if they were eyes—glimmered with a liquid darkness that seemed to drink in what light dared to touch it. "You've come too far," the creature hissed, its voice a slithering sound, a blade across stone. Rory swallowed hard, backing away until her heel collided with the well's base. The air around her thickened; every breath felt like inhaling through a bog. "Leave," the Guardian from the well pleaded. "Or you won't." "How?" she choked out, desperation rising. When had the Grove become so malicious? Had it always been this way, and she had simply never noticed? The creature moved forward, steps deliberate and silent. Its gaze never wavered from her, pinning her with a malignant kind of curiosity. Rory took one halting step back, gripping the pendant so hard the silver bit into her palm. "Why me?" she whispered, though she doubted there would be an answer. To her surprise, the creature halted. Its head tilted, reptilian in its calculation, as if genuinely considering her question. "You carry what belongs to us," it said finally, a single claw pointing directly to the Heartstone Pendant. "What do you mean?" she demanded, taking another perilous step back. The well's edge pressed firmly against her spine now. "It was never meant for human hands," it said, voice a soft caress that belied the menace laced underneath. The pendant pulsed once, as if in agreement, and Aurora remembered the warning Eva had given her when she first took possession of it: "Some gifts are meant to be burdens." The tension broke. Rory turned and ran, following the path back as best she could, her feet moving faster than her mind could process. The noises returned, louder now—a cacophony of laughter, whispers, and the omnipresent rustling. Each sound felt like another layer of reality peeling away, revealing the raw, unnatural core beneath. She stumbled, catching herself against a tree, the bark scraping her palms. Her breaths were ragged, reality slipping as the time-warping effect of the Grove muddled her senses. She had to find the standing stones, the boundary between this nightmare and the world she knew. More shadows darted at the edges of her vision, unseen but felt. The humid press of their presence squeezed at her lungs, her chest tightening with every step. She clung to the pulsing warmth of the pendant, its rhythm a desperate lifeline. Finally, she burst into the original clearing. The standing stones loomed, ancient and silent, and with a burst of energy fueled by sheer will, she fled past them. As she crossed the threshold, Rory collapsed to her knees, gasping for the cold, clear night air of Richmond Park. Behind her, the grove fell silent, its myriad of sounds cut off as neatly as a slashed ribbon. She could only lie there, feeling the damp earth beneath her, her body shaking, the pendant now cool against her chest. One thing was clear: The Heartstone Pendant had secrets—and so did the Grove. Secrets that had marked her, claimed her in ways she couldn't yet fathom. As she lay panting on the familiar grounds of Richmond Park, she knew one grim truth—her journey had only just begun.
