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 ancient oak trees loomed like silent guardians, their gnarled branches framing the entrance to the Fae Grove. Aurora, her heart pounding in her throat, stepped cautiously under the archway of intertwined branches, leaving the modern world behind. Night had fallen, casting Richmond Park in a shroud of darkness, but here in the Grove, a mystical light illuminated the clearing. Wildflowers danced in an unfelt breeze, their colors vibrant even in the spectral glow. A faint hum, like the distant thrumming of insect wings, filled the air, setting her nerves on edge. Rory had received a mysterious message—a simple location and time, no explanation. It had come just as she was finishing her delivery route, a solitary run through the park's winding paths. Intrigued yet cautious, she had made her way here, to this secretive clearing, only to find herself even more alone and uncertain. She looked down at the Heartstone Pendant resting against her chest, its silver chain cool against her skin. Its warm crimson glow seemed almost in sync with her own heartbeat. She had no idea who had sent it to her or why, but it had arrived in the mail the previous week, a shimmering enigma that had pulled her inexorably toward this very spot. The air grew heavy with anticipation, and Rory swore she could feel unseen eyes upon her, tracking her every movement. She spun around, scanning the perimeter marked by the towering oaks, but nothing seemed amiss. The wildflowers continued their serene dance, and the grove whispered with the unintelligible language of the wind. "Hello?" she called out, her voice breaking the unnatural stillness. "Anyone there?" No answer came, save for the persistent, mysterious hum, now joined by the distant hooting of an owl. Her breath formed faint clouds in the crisp night air, giving her a surreal sense of detachment. Trust your instincts, she thought. There's something here, something hidden. As if in response to her unspoken thoughts, a nearby patch of wildflowers rustled as though disturbed by an unseen force. Rory's hand flew to the pendant, her heart quickening. Taking a cautious step forward, she studied the spot where the flowers had twitched, half expecting to find a woodland creature or an errant breeze. But there was nothing. The clearing felt smaller now, as though the standing stones had shifted closer together, tightening the boundaries of this hidden realm. Aurora's breath quickened as she realized the light had dimmed imperceptibly, the wildflowers losing their vibrant hue. She was certain now; this place was not what it seemed. "Why did you bring me here?" she whispered into the gloom, her words carried away by the whispering wind. The pendant began to glow brighter, its pulse quickening like a beacon seeking to draw attention. In that moment, she knew it was not just a trinket, but a key, a conduit to something more. As her gaze fixed on the crimson stone, the hum intensified, and the world seemed to twist around her. Shadows danced at the edge of her vision, forming shapes that eluded her direct stare. Rory's stomach dropped as she sensed the true nature of this place, the hidden boundary between realms. The ground beneath her feet seemed to shift, and she stumbled, catching herself against a gnarled tree root. Her fingers dug into the rough bark, searching for stability in a world that suddenly felt fluid and unreal. Her breath came in quick gasps, each exhalation visible in the cold air. Then, as quickly as it had begun, the surreal sensation passed. The light stabilized, and the hum receded, leaving her shaky and disoriented. Rory stood upright, smoothing her hands down the front of her jacket, a physical attempt to steady her rattled nerves. Taking slow, deliberate steps, she made her way toward the center of the Grove, drawn by an unseen force. With each step, the pendant's glow increased, casting an ethereal light that danced around her. The grove seemed to react to her presence, the wildflowers swaying in her wake, as if in greeting or farewell. At the heart of the clearing, Rory stopped, closing her eyes and taking a deep, steadying breath. She reached for the pendant, her fingers wrapping tightly around the cool stone. "Show me," she demanded, her voice strong and steady, belying her inner turmoil. In response, the world shifted once more, but this time, she was prepared. The standing stones shimmered, no longer solid but translucent portals into another realm. The boundaries between worlds thinned, revealing a glimpse of a place beyond—a realm of shadows and dancing lights, where figures moved with otherworldly grace. Aurora's breath caught at the sight of the Faerie realm, a place she'd only ever heard whispered tales about. It was beautiful, enchanting, and dangerous—a place where humans were seldom welcome. The pendant pulsed with a life of its own, as if yearning to return to its home. Then, as suddenly as it had opened, the veil closed, leaving her alone in the earthly grove. She released a breath she hadn't known she'd been holding, her heart racing. "I see you now," she murmured, addressing the unknown force that had led her here. "But why me?" The pendant continued to glow in her grasp, its warmth a silent reassurance. She knew this was only the beginning, a first step into a hidden world. She just hoped she was ready for what came next. With one last lingering look around the mystical clearing, Rory turned and retraced her steps, leaving the Fae Grove behind. As she stepped back into the mortal realm, the pendant's glow dimmed, returning to its usual quiet radiance. The night air, once again ordinary, caressed her face as she made her way back to the city streets, leaving the supernatural encounter behind. But Aurora Carter knew that her life had just taken an irrevocable turn, and she was eager to uncover the mysteries that awaited her.
