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, known to few in this hidden corner of London as Rory, stepped through the ancient oak standing stones marking the boundary of the Fae Grove, the trees' gnarled silhouettes
looming
like
sentinels
against the moon. She had always felt an
otherworldly
pull to this place, a spot where the fabric between worlds
was said
to be at its thinnest. Tonight, she had a purpose for braving its isolated depths: to understand the strange, pulsing warmth emanating from the Heartstone Pendant around her neck. The silver chain glinted, catching slivers of moonlight that
managed to
penetrate the canopy above, as she made her way deeper into the clearing. Wildflowers, b
looming
defiantly in the dead of night, swayed
gently
in the breeze, their colors muted in the pale light. Rory's bright blue eyes, accustomed to the city's harsh glare, took a moment to adjust to the Grove's soft,
ethereal
luminescence. Her straight, shoulder-length black hair blended with the shadows, rendering her all but invisible as she moved. Her
footsteps
, the only sound in the stillness,
seemed to
echo
more in her mind than in reality, each step a reminder that time moved differently here. An hour within the Grove's embrace could mean anything from mere minutes to lost days outside its bounds. The thought
sent a shiver down
her spine, but Rory pressed on, driven by a mix of curiosity and the unsettling feeling that the Heartstone Pendant
was awakening
to something. As she reached the clearing's center, Rory paused, her gaze sweeping the area. The crescent-shaped scar on her left wrist
seemed to
prickle with a memory, but it was the pendant that held her attention. Its deep crimson gemstone pulsed with a faint, inner warmth, more pronounced here than it had ever been in the bustling streets of London. She lifted the pendant, its size no larger than a thumbnail, and turned it, watching as the light danced within its depths. "A sign of what?" Rory whispered to herself, the sound swallowed by the Grove's
oppressive
silence. She had received the Heartstone Pendant from an unknown benefactor, with no message or indication of its origins, save for the faint Dymas inscription
etched
into the back of the silver chain's clasp. The stillness around her
began to
feel heavy,
oppressive
, as if the Grove itself
was waiting
. Rory's cool-headed nature, honed from years of
navigating
Cardiff's legal circles and later, the complexities of her own turbulent life,
began to
falter under the
weight
of the unblinking, dark watches of the trees. It started with the sound of leaves shifting, too delicate to be attributed to the wind, too intentional to be a small animal. Rory's head turned
sharply
to her right, her eyes narrowing as she strained to see into the darkness. The movement stopped as abruptly as it had begun, leaving behind a silence more unsettling than any sound. She took a deep breath, the air crisp with the scent of wildflowers, and continued her examination of the pendant, though her attention was now divided. The pulse within the gemstone
seemed to
quicken, or perhaps it was her heart, racing in
anticipation
of... something. A
flicker
of movement caught at the edge of her vision, gone before she could turn. Rory spun around, her back to the center of the clearing now, her eyes scouring the shadows. "Who's there?" she called out, her voice steady, though a tremor threatened to undermine her composure. The response was silence, and in its depths, a feeling
grew—that she
was
being encircled
,
slowly
, by unseen presences. Rory's grip on the pendant tightened, its warmth now a comforting
beacon
against the creeping chill. She took a step back, her heel catching on a hidden root. The jarring movement was enough to break the spell. With a swift motion, Rory slipped the pendant under her jacket, the silver chain cool against her skin, and began a deliberate, unhurried walk towards the boundary stones. Each step forward
was met
with an unshakeable sense that she was moving further away from escape, the standing stones remaining steadfast, yet somehow, impossibly, more distant. The wildflowers, once a gentle, soothing presence, now
seemed to
reach for her, their muted colors transformed into
macabre
, grasping fingers in her heightened state. It was then that the whispers began, soft, indistinguishable murmurs that wove in and out of the wind, always just out of reach. Rory quickened her pace, her heart pounding in her ears, drowning out the whispers, though their presence lingered, a cold, clammy touch on the back of her neck. She burst through the ancient oak standing stones, the city's distant hum and the moon's pale light enveloping her like a balm. Rory didn't stop running until she was back in the heart of Richmond, the Grove's terrors swallowed by the comforting anonymity of the night crowd. Breathless, she finally paused, looking back towards the unseen depths of Richmond Park, the Fae Grove hidden within its shadows. The Heartstone Pendant, still clutched in her hand, its pulsing warmth now a burning brand, reminded her that some mysteries were better left unexplored, yet it was too late. The darkness had seen her, and Rory could only wonder when it would come looking.
