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 edge of the Fae Grove, the ancient oak standing stones
looming
like silent
sentinels
in the moonlight.
The air was thick with
the scent of wildflowers, their vibrant colors muted in the silvery glow. She adjusted the strap of her messenger bag, the
weight
of the Heartstone Pendant pressing
lightly
against her chest. The deep crimson gem pulsed faintly, a subtle warmth that
seemed to
seep into her skin. She had come here at Eva's insistence, a cryptic message urging her to find something important in the Grove. Rory had learned to trust Eva's instincts, even when they led her to places like this — places that felt like they existed on the edge of reality. She took a deep breath, the cool night air filling her lungs, and stepped past the standing stones. The moment she crossed the threshold, the world
seemed to
shift. The sounds of the city faded, replaced by an eerie stillness. Time moved differently here, she reminded herself. An hour inside could be minutes or days outside. She glanced at her
watch
, noting the time before she ventured deeper into the clearing. The wildflowers brushed against her legs as she walked, their petals soft and cool. The trees around her were ancient, their gnarled branches twisting towards the sky like skeletal fingers. She felt a shiver run down her spine, but she pushed it aside. She had a job to do. As she moved further into the Grove, the sense of wrongness
began to
build. It was subtle at first — a rustling in the underbrush that
seemed to
o deliberate, shadows that
flickered
at the edge of her vision. She paused, listening intently, but heard nothing beyond the whisper of the wind through the leaves. "Eva?" she called out
softly
, her voice barely more than a whisper. There was no response, only the
oppressive
silence pressing in around her. She tightened her grip on the strap of her bag and continued forward, her eyes scanning the darkness for any sign of movement. The path wound deeper into the Grove, the trees growing denser, their branches intertwining overhead to form a canopy that blocked out the moonlight. Rory's heart
began to
pound in her chest, the rhythmic thud
echo
ing in her ears. She reached up to touch the Heartstone Pendant, its warmth a small comfort in the encroaching darkness. A sudden rustling to her left made her freeze. She turned
slowly
, her eyes straining to see through the gloom. For a moment, she thought she saw a figure standing among the trees, but when she blinked, it
was gone
. She swallowed hard, her mouth dry, and forced herself to keep moving. The path led her to a small clearing, the ground carpeted with soft moss. In the center stood a stone altar, its surface worn smooth by time. Rory approached
cautiously
, her eyes darting around the clearing. The sense of being
watch
ed was almost overwhelming now, a prickling sensation at the back of her neck. She reached the altar and placed her hand on its cool surface. The Heartstone Pendant pulsed more strongly, the warmth spreading through her chest. She closed her eyes, trying to focus, to sense whatever it
was that Eva
had sent her to find. A soft whispering filled the air, like the rustle of leaves in a breeze. Rory's eyes snapped open, her heart racing. The whispering grew louder, more insistent, but she couldn't make out the words. She turned in a slow circle, her eyes wide, searching for the source of the sound. The shadows at the edge of the clearing
seemed to
shift and move, coalescing into vague shapes that danced just beyond her vision. She took a step back, her breath coming in short, shallow gasps. The whispering grew louder still, a
cacophony
of voices that
seemed to
come from all around her. "Who's there?" she demanded, her voice trembling. The whispering stopped abruptly, leaving an
oppressive
silence in its wake. Rory's pulse pounded in her ears, the silence almost deafening. A figure stepped out of the shadows, its form indistinct in the darkness. Rory's breath caught in her throat as she
tried to
make out its features. It moved closer, and she could
see that it
was a woman, her face pale and gaunt, eyes hollow and empty. "Eva?" Rory whispered, her voice barely audible. The woman shook her head
slowly
, a sad smile playing on her lips. "Not Eva," she said, her voice a soft, mournful
echo
. "But I know why you're here." Rory took a step back, her mind racing. "Who are you?" she asked, her voice stronger now, though still
tinged
with fear. The woman tilted her head, her empty eyes seeming to bore into Rory's soul. "I am a guardian of this place," she said. "And you are not welcome here." Rory's hand went to the Heartstone Pendant, its warmth a small comfort against the chill that had settled over her. "I was sent here by a friend," she said, her voice steadying. "I'm looking for something important." The woman nodded
slowly
. "I know what you seek," she said. "But it comes at a price." Rory's heart sank. She had known this wouldn't be easy, but the
weight
of the woman's words pressed down on her like a physical force. "What price?" she asked, her voice barely more than a whisper. The woman stepped closer, her form becoming more solid, more real. "You must leave something of yourself behind," she said. "A piece of your soul, to bind you to this place." Rory's breath caught in her throat. She had heard stories of the Fae and their bargains, but she had never imagined she would be faced with one herself. She glanced down at the Heartstone Pendant, its faint glow a reminder of why she was here. "I'll do it," she said, her voice firm. "Tell me what I need to do." The woman smiled, a sad, knowing smile. "Place your hand on the altar," she said. "And speak your name." Rory hesitated for a moment, then stepped forward, her hand trembling as she placed it on the cold stone. She took a deep breath, her eyes meeting the woman's hollow gaze. "Aurora Carter," she said, her voice steady. The woman nodded, and a sudden pain shot through Rory's hand, spreading up her arm and into her chest. She gasped, her vision blurring as the pain intensified. She felt a part of herself
being pulled
away, a piece of her soul torn from her body. When the pain finally subsided, Rory collapsed to her knees, her breath coming in ragged gasps. The woman
was gone
, the clearing silent once more. She felt a deep emptiness inside her, a void where a part of her soul had once been. But she had what she came for. She reached into her bag and pulled out a small, intricately carved box. Inside was a key, its surface
etched
with ancient runes. She had no idea what it opened, but she knew it was important. Rory stood
slowly
, her legs trembling. She glanced around the clearing one last time, then turned and made her way back down the path. The sense of wrongness still lingered, but she pushed it aside. She had what she needed, and she would find a way to make it right. As she stepped back through the standing stones, the world shifted once more. The sounds of the city returned, the
oppressive
silence lifting. She glanced at her
watch
, noting that only a few minutes had passed. Rory took a deep breath, the cool night air filling her lungs. She had faced the darkness and come out the other side. But she
knew that the
price she had paid would haunt her for the rest of her life.
