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 stepped out of the mist-shrouded darkness of Richmond Park and into the Fae Grove, her eyes adjusting
slowly
to the soft,
ethereal
light that permeated the clearing.
The air was heavy with
the sweet scent of wildflowers, and the ancient oak standing stones
loomed
above her, their gnarled branches twisted into impossible shapes. She had
been drawn
to this place for a reason, though she couldn't quite put her finger on why. A sense of restlessness had been building inside her for weeks, ever since the strange package had arrived with no return address, containing only the Heartstone Pendant and a cryptic note that read: "For the lost, a
beacon
in the dark." As she walked deeper into the grove, the silence
began to
unnerve her. The trees
seemed to
absorb sound, leaving only an
oppressive
stillness that made her skin prickle. Rory shivered, despite the warmth of the summer evening, and wrapped her arms around herself. She had always
been drawn
to the unknown, the unexplained, and the Fae Grove was rumored to be a place where the boundaries between worlds were thin. But now, surrounded by the
oppressive
quiet, she wondered if she had made a terrible mistake. The pendant, which she wore around her neck, pulsed faintly with warmth against her skin, a gentle reminder that she wasn't alone. But the comfort it offered was short-lived, as her gaze caught on movement out of the corner of her eye. She spun around, but there was nothing there. The trees
seemed to
be shifting, their branches tangling together in a way that seemed almost... intentional. Rory's heart quickened, and she took a deep breath, telling herself it was just the wind. She continued on, her
footsteps
quiet on the soft earth, as she made her way deeper into the grove. The trees
seemed to
be closing in around her, casting long, ominous shadows on the ground. Every step felt like a betrayal, as if she was
being herded
towards some unknown fate. The pendant's warmth grew stronger, and she reached up to touch it, her fingers closing around the cool silver chain. A faint humming noise
began to
build in her ears, like the quiet buzzing of a harp string. It was a sound that
seemed to
come from all around her, and yet, from nowhere at all. Rory's skin crawled, and she spun around, trying to locate the source of the noise. But there was nothing to see. The humming grew louder, more insistent, and she felt a creeping sense of dread that she couldn't shake. She
tried to
tell herself it was just the wind, or the trees, or her own imagination playing tricks on her. But deep down, she knew it was something more. The Fae Grove was a place of ancient power, a threshold between worlds, and she had stumbled into it uninvited. The thought
sent a shiver down
her spine, and she quickened her pace, her eyes scanning the trees for any sign of movement. The humming stopped, abruptly, leaving an
oppressive
silence in its wake. Rory froze, her heart pounding in her chest, as she waited for something to happen. And then, out of the corner of her eye, she saw it. A figure, tall and
imposing
, standing just beyond the edge of the clearing. She spun around, but there was no one there. The trees
seemed to
be shifting again, their branches weaving together in a way that seemed almost... malevolent. Rory took a step back, her eyes scanning the trees, searching for any sign of movement. The pendant's warmth had grown to a gentle heat, and she felt a strange, thrumming energy building inside her. She knew, with a certainty that she couldn't
explain, that she
was not alone in the grove. Something
was watching
her, waiting for her to make a wrong move. She took another step back, her heart racing, as the trees
seemed to
close in around her.
The air was thick with
tension, and she could feel the
weight
of the grove's power bearing down on her. The pendant's glow
seemed to
be growing stronger, illuminating the darkness with an eerie,
otherworldly
light. Rory knew she had to get out of there, before it was too late. She turned to run, but her feet seemed rooted to the spot. The trees
loomed
above her, their branches tangling together in a way that seemed almost... deliberate. And then, out of the darkness, a low, whispery voice spoke a single word: "Welcome."
