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 crunch of gravel beneath Rory's boots was the only sound that broke the stillness of the night as she made her way through Richmond Park. The darkness
seemed to
swallow her whole, the only light coming from the faint moon overhead and the soft glow of her phone's screen, which she'd set to a dim red hue to preserve her night vision. According to her research, the Fae Grove
was hidden
somewhere within the park's boundaries, and she'd finally pinpointed its location after weeks of searching. Rory's eyes scanned the surroundings, the ancient oak standing stones that marked the boundary of the grove supposedly hidden just beyond the next copse of trees. She quickened her pace, a shiver running down her spine as the trees
seemed to
close in around her. Her hand instinctively rose to the Heartstone Pendant, the silver chain feeling cool against her skin, the deep crimson gemstone pulsing with a faint warmth. It had been behaving strangely all day, its gentle hum growing more insistent as the hours passed. As she pushed through the trees, the air
seemed to
thicken, like a
palpable
fog
was rolling
in. Rory's skin prickled, her bright blue eyes scanning the darkness for any sign of movement. The trees
loomed
above her, their branches like skeletal fingers reaching for the sky. She'd always loved the atmosphere of Richmond Park at night, but now it felt
oppressive
, as if the
very
forest
was watching
her. The sound of running water caught her attention, and Rory followed its gentle burble, her feet leading her toward a clearing. The trees parted, revealing a secluded glade, the wildflowers that b
loomed
year-round swaying
gently
in the breeze.
The air was heavy with
the scent of honeysuckle and something else, something
sweetly
decaying. Rory's nose wrinkled in distaste. In the center of the clearing stood a massive stone, its surface
etched
with ancient symbols that glowed with a faint,
ethereal
light. The Heartstone Pendant pulsed more rapidly now, as if it sensed something. Rory's
eyes narrowed
, her mind racing with the implications. This was it – the Fae Grove. She'd finally found it. As she approached the stone, the sounds of the forest grew louder, the rustling of leaves, the snapping of twigs, and the distant hooting of an owl. But beneath it all, Rory detected a low, steady hum, like the quiet buzzing of a bee. It was a sound that didn't belong, a sound that made her skin crawl. She circled the stone, her eyes scanning the surrounding trees, but there was nothing. No sign of movement, no sign of life. The hum grew louder, more insistent, and Rory felt a creeping sense of unease. She'd been so focused on finding the grove that she'd never stopped to consider what might be waiting for her here. The wind picked up, rustling the leaves and sending the wildflowers swaying violently. The hum stopped, and an
oppressive
silence fell over the clearing. Rory's heart thudded in her chest as she realized she was not alone. She spun around, but there was nothing to see. "Aurora Carter," a low, raspy voice whispered, the sound seeming to come from all around her. Rory's eyes snapped toward the stone, her hand instinctively rising to the pendant. "Who's there?" she demanded, trying to keep her voice steady. The voice didn't respond, but the hum began again, this time louder, more menacing. The air
seemed to
vibrate with it, making Rory's teeth ache. She took a step back, her eyes darting toward the trees, but there was still nothing to see. Suddenly, the wind died, and the hum ceased. The silence was absolute, a heavy, suffocating blanket that pressed down on Rory. She felt like she was being watched, like unseen eyes were boring into her skin. The moon overhead
seemed to
dip, casting the clearing in an even darker shadow. Rory's heart
was racing
now, her breath coming in short, sharp gasps. She knew she had to get out of there, but her feet seemed rooted to the spot. And then, out of the corner of her eye, she saw it. A movement, a
flicker
of something at the edge of her vision. Rory spun around, but there was nothing. The movement came again, this time closer, and she caught a glimpse of something pale, something that didn't belong in this world. The Heartstone Pendant pulsed wildly now, its warmth spreading through her chest. Rory knew she had to get out of the grove, to escape whatever horror
was lurking
just out of sight. She turned to run, but her feet seemed heavy, unresponsive. The pale thing moved again, closer this time, and Rory caught a glimpse of eyes, eyes that glowed with an
otherworldly
light. She
tried to
scream, but her voice
was frozen
in her throat. The darkness closed in around her, a suffocating, crushing
weight
that pressed down on her chest. Rory's vision
began to
blur, the last thing she saw the glowing eyes, watching her, waiting for her.
