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 darkness within the Fae Grove was almost
palpable
, a living entity that wrapped around Rory like a shroud. She stepped
cautiously
, her eyes straining to pierce the gloom. The ancient oak standing stones, once a reassuring presence, now
loomed
like
sentinels
, their branches
etched
against the faint moonlight like skeletal fingers. Rory's hand instinctively went to the Heartstone Pendant, its deep crimson gemstone pulsing faintly with warmth against her chest. She had come to the Grove seeking
solace
, a respite from the turmoil that had been brewing in her life. The pendant, a gift from an unknown benefactor,
seemed to
hum with an
otherworldly
energy, drawing her to this place. Yet, as she walked deeper into the clearing, a growing sense of unease
began to
crawl under her skin.
The air was heavy with
the scent of wildflowers, their delicate blooms swaying in the breeze like ghostly whispers. Rory's footfalls
echoed
through the stillness, the only sound in a silence that felt
oppressive
. She slowed her pace, her senses on high alert. Something didn't feel right. A faint rustling in the underbrush caught her attention. Rory's heart quickened as she spun toward the noise, her eyes scanning the darkness. A rabbit, its eyes glowing like lanterns in the dark, darted across her path. She exhaled a shaky breath, chiding herself for the jumpiness. But the feeling of being watched persisted. As she continued through the Grove, the silence
began to
take on a life of its own. The trees
seemed to
loom closer, their branches tangling overhead like a canopy of skeletal fingers. Rory's skin prickled with gooseflesh. She could have sworn she heard the soft creak of a branch, the faint whisper of a voice on the wind. But whenever she turned to listen, there was nothing. A faint, flickering glow caught her attention. A wildflower, its petals shimmering like moonlight,
seemed to
be growing in the center of the clearing. Rory approached
cautiously
, her hand still clutching the pendant. As she drew closer, the flower's glow intensified, casting an
ethereal
light across the surrounding trees. Suddenly, the petals folded inward, plunging the clearing into darkness. Rory's breath caught in her throat. The silence was absolute, a vacuum that
seemed to
suck the air from her lungs. And then, a low, keening wail
echoed
through the Grove, sending shivers down her spine. The sound
seemed to
come from all directions at once, a mournful cry that spoke of ancient sorrow and loss. Rory's
heart pounded in her chest
as she spun around, trying to locate the source of the wail. But there was nothing to see. The trees stood motionless, their branches creaking
softly
in the breeze. The wail grew louder, more insistent, until it
seemed to
be coming from inside her own head. Rory's vision
began to
blur, the darkness closing in around her like a suffocating shroud. She stumbled, her foot catching on a hidden root. As she fell, the pendant's glow surged, casting an eerie light across the surrounding trees. For a moment, Rory saw something moving at the edge of her vision – a shadowy figure, its eyes glowing like lanterns in the dark. She
tried to
scream, but her voice
was lost
in the wail, which
seemed to
be building to a crescendo. And then, everything went black. When Rory came to, she
was lying
on the forest floor, the moon overhead casting an silver glow across the clearing. The wail had stopped, replaced by an
oppressive
silence. She sat up
slowly
, her head spinning, and looked around. The wildflowers still b
loomed
, their delicate petals swaying in the breeze. But something was different. The air felt heavier, the shadows deeper and more
sinister
. Rory knew, with a certainty that chilled her to the bone, that she was not alone in the Grove. The pendant, still pulsing with warmth against her chest,
seemed to
be urging her to leave. She scrambled to her feet, her eyes scanning the darkness for any sign of movement. And then, she turned and ran, not stopping until she stumbled out of the Grove and into the bright, shining lights of the mortal world.
