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 night sky hung above Aurora Carter like an inky shroud, the stars mere pinpricks of distant light that did little to comfort her as she trod softly through the Fae Grove. She felt each step on the damp earth, a slight squelch accompanying the rhythmic thud of her heartbeat, the sound muted beneath the thick canopy of trees. The air was cool, brushing against her skin in a way that seemed almost palpable. Rory — as her friends preferred to call her — couldn't remember why exactly she had come here, to this strange, isolated nook of Richmond Park. All she knew was the pull she felt, a compulsion tugging at her reasoning, as if some invisible thread led her deeper into the Grove's mysteries. The ancient oak standing stones rose around her like silent sentinels, the rough bark glinting faintly under the sparse moonlight. Rory shivered, not just from the cold, but from an innate wrongness that nettled her senses. It was an uncanny feeling, as though reality itself bent and warped at the edges here, unstable and unpredictable. Her bright blue eyes flitted over the wildflowers that flourished unnaturally abundant, their colors vibrant against the shadowy backdrop. It unsettled her further; nothing in the Grove obeyed the usual rules. She pressed a hand to her throat, against the Heartstone Pendant that hung there. The deep crimson gem felt warm, a reassuring pulse against her skin, as if acknowledging her presence and whispering a secret in return. The Grove seemed alive in a way no other place in her life had been — an animate presence that thrummed with something ancient, alien. Rory strained her ears, listening for the sounds of nocturnal creatures, the expected rustle of leaves, but what came instead was a near silence, punctuated by an occasional whispering breeze. A sound that shouldn't have been there threaded itself through the air, a low, melodic hum, as though someone — or something — sang just beyond the sight. Her instincts screamed, telling her to turn back, to run and never return to such an eerie enclave, but curiosity held fast. Rory had always had a weakness for puzzles, for the seductive wile of the unknown. Perhaps it was the barrister’s blood in her veins, always hungering for answers, for truth hidden beneath layers of misdirection. A soft crunch, like footsteps trailing her own, made her whip around, her breath seizing painfully in her chest. The Grove unfolded behind her, unchanged, yet different — deeper shadows, their forms shifting uncomfortably close. Her eyes darted past, looking for the source of the sound, but there was nothing, no one, just the stillness draping over everything like a suffocating film. Rory swallowed hard, dragging her gaze upwards, suddenly hyperaware of how small she was beneath the expansive dark. Her skin crawled, every fine hair prickling, as the sensation of being watched crept over her like an unwelcome breeze threading through the leaves. The relentless thud of her heart echoed in her ears, intertwining with the forest's thrum, conjuring an odd harmony that spoke of caution, of danger unseen. She reached for her phone instinctively, wanting the bitter comfort of artificial light, but found only the silence of digital death as it lay useless — a small, apologetic rectangle in her hand. The Fae Grove seemed to guzzle battery life like the labyrinth it was, swallowing time and logic whole, leaving only Rory and the growing darkness. The moon had shifted, or the canopy had thickened; it was impossible to pin a solid explanation in this pocket between places. Rory braced herself, forcing logical thought to slice through the thickening fog of apprehension that clung to her like cobwebs. There was a reason she had come here, she reminded herself, even if it now evaded her grasp. She moved forward once more, defying the chill that soaked into her bones, the ever-present lull of that phantom singer fluttering at the periphery of her consciousness. An hour inside the Grove could be minutes or days outside; she had to be cautious, careful not to lose herself amid the capricious currents of the Fae-infused world. Her foot pressed down on something that wasn't earth, wasn't stone. Wood? No. Bone? The thought twisted her insides; but as she glanced down, it revealed only brittle branches sculpted like skeletal fingers. A mirthless smirk tugged at her mouth. Perhaps the Grove had its sense of humor, too. Aurora shied from the sinister imagining, a futile attempt to recapture composure swaddling her resolve. She had brushed shoulders with darkness before and survived. Evan’s violence had been tangible, raw. This, she could manage — a haunting in the memory of trees and stone. Or so she hoped. A sudden motion sliced through the corner of her vision, a shadow flitting between trees, dancing just beyond clarity. Her muscles locked momentarily, the surge of adrenaline forcing them once more as she spun, confronting the apparition. "Who's there?" she called, hating the tremor of uncertainty that rippled through her voice, far weaker than she'd intended. Silence answered, pregnant with unspoken possibilities. Rory gritted her teeth, determination flaring defiantly against the growing certitude of unseen company. She had walked here willingly, lured by clandestine whisperings that now waited to be unveiled. Turning away again, the Heartstone warmed at her throat, its glow another heartbeat against her own. Each step felt orchestrated, part of a larger symphony composed by the Grove itself, luring her deeper into its snare. Off to the side, a stand of trees loomed, the branches knotting above in an embrace that seemed... purposeful. It was there the song surged, louder now, a dirge both ancient and immediate, twisting itself into the natural rhythm of the place. At the heart of the copse lay a clearing, bathed in the pallor of moonlight that found purchase through the scattered foliage. It was there Rory saw her. A woman draped in the ethereal shimmer of the grove, woven from light and shadow, standing beside the central oak as if she'd always belonged. "I’ve been waiting," the woman said, her voice the song Rory had followed, pied piper to the mysteries she unwittingly courted. Her form was indistinct, face lost in the interplay of celestial glow and velvet dark. But the eyes — those were as blue as Rory's own, mirroring her soul back at her. "Who are you?" Rory demanded, her voice bolder despite the placid terror that clawed at the walls of her resolve. "I am what you seek," the figure whispered, extending a hand that flickered in and out of existence, fragments of tangible reality fading into the ether. "But there is a price, always a price." The forest shifted, shadows lengthening, the expectancy in the air so thick Rory feared she might choke on it. This was the heart of the Grove's secret, a confluence of destiny and choice, waiting upon her decision. Aurora hesitated, her instincts warring with her curiosity, the quest for knowledge conflicted with the basest sense of self-preservation. Yet the semblance of her own eyes in another face — that struck her, a peregrine star burning with silent promises unmet. She stepped forward, faltering but resolute, the gloaming of the Grove enfolding her like a forgotten vow, and reached out. The tendrils of reality re-weaved around her as the woman's smile deepened, the enigma of the Grove cocooning them, time unspooling anew in its sovereign dance. In that embrace, Aurora found a whisper of truth she hadn't anticipated, her reflection staring back with understanding only a kindred spirit could convey. The woods sighed, a low, resigned moan that echoed beyond the confines of mortal ears, the pendant's warmth resonating in response, guiding her into the uncertain tapestry of what lay ahead.
