System
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 night air
trembled
with a stillness that breathed unease. Aurora Carter stood at the boundary between Richmond Park and the Fae Grove, her
footsteps
swallowed by the muted earth beneath her shoes. Dark trees
loomed
around her, their outlines jagged against the shimmering starlight, casting long, creeping shadows. She had come here for answers, clutching the Heartstone pendant—a deep crimson gem that hung heavy at her throat on a silver chain. It pulsed
softly
against her collarbone, warm and reassuring, but the serenity it offered felt out of place under the watchful gaze of ancient oaks. Aurora drew a deep breath, steadying herself. She was no stranger to places that defied logic, having
navigated
the bustling streets of London and the labyrinth of her own mind after fleeing an abusive past. Yet this quiet clearing had an essence that set her on edge, a promise of secrets wrapped in the odd silence that enveloped her. The grove
seemed to
breathe, though it lacked the
symphony
of life she expected; there were no crickets chirping, no rustle of leaves, just an expectant hush that coiled around her like a living thing. Moving further into the grove, she stepped between the ancient standing stones, their gnarled bark and intricately twisted forms bearing a
weight
of history. Flickering lights danced in her peripheral vision, blinking in the corners of her sight like fireflies at dusk. When she turned, nothing stirred. Was it merely the mind's trickery, or had something
truly
brushed against her consciousness with its
ethereal
fingers? The Heartstone grew warmer, a pulse that quickened as if
echo
ing her heartbeat. She pushed the sensation aside, focusing on her purpose. Eva had
insisted that this
grove held the key to understanding more about their shared past, about the Fae legacy that lingered in their bloodlines. But as Aurora
delved
deeper, determination fought with a gnawing discomfort that spread like ivy up her spine. A rustling broke the fragile silence, as if something stirred beneath the roots of the ancient oaks. She glanced toward the sound, heart quickening. The chill air prickled against her skin; it felt as though the shadows themselves whispered secrets meant only for the wind. Taking a deliberate step forward, she called out, her voice cutting through the murk of silence. “Hello? Is someone there?” Only the night replied, thick and heavy. Doubt clawed at her insides. She had promised herself this wouldn’t be the night she succumbed to fears rooted in the past, that she wouldn't be haunted by the trauma Evan had imposed, but the grove beckoned dread with the familiarity of an unwelcome visitor. With a resolute nod to herself, she pressed on, drawn by the
weight
of history in the air—a promise held within the Heartstone that chanted
softly
against her skin. Yet, the deeper she ventured, the flickering lights intensified, as if teasing her resolve. Once again, she caught movement from the corner of her eye, too quick to identify a shape, but insistent enough to curl her fingers around the pendant. Chill crept into the air, and a sudden gust rustled the branches—an unnatural sound that felt like a warning. The grove whispered, a language of rustles and sighs. It spoke to her of warnings, urgency wrapping around her with each heartbeat. Aurora pressed on, her own
footsteps
feeling alarmingly audible against the quickening tempo of the night. A trail of wildflowers b
loomed
beneath her feet, vivid bursts of color that seemed alive, yet they swayed in unseen currents, curving away from her path as if guiding her deeper into the grove's clutches. Their beauty
was disorienting
, mocking the anxiety that washed over her. She hesitated, glancing around—the stones
loomed
like watchful
sentinels
, their surfaces worn and twisted, bearing silent witness to the passage of uncounted years. In the pit of her stomach, dread coiled tighter. It lurked in the spaces between her thoughts,
whispering that she
was not alone, that something had followed her here into this pocket world. A shadow
flickered
just beyond her vision, quick and elusive. When she looked directly, nothing stirred, only the shapes the trees cast against an alien sky, where stars blinked like hesitant witnesses. “Stay calm, Rory,” she whispered to herself, forcing a steady breath. Her childhood nickname felt foreign here, unwelcome
amidst
the pulse of
otherworldly
energies. It was both grounding and disconcerting, as if she
were compelling
herself to retain some element of control within a place designed to strip her of it. Another noise erupted from the periphery, close enough this time that her heart raced—an
echo
of rustling leaves, but with a heavier
weight
behind it. Aurora turned
sharply
, gripping the Heartstone pendant as if it were a lifeline. The glow of the gem increased, reddish light casting eerie shadows across the grove. “Show yourself!” she commanded, emboldened by adrenaline and fear. The challenge
hung in the air
, vibrating with an intensity that left the hairs on her arms standing at attention. Silence enveloped her, thick and suffocating, pressing in with
tangible
weight
. The stillness seemed alive, throbbing with
anticipation
, before dissolving into a
palpable
tension that thickened the air. Time felt warped here; she could feel the minutes slip like sand through her fingers. Each heartbeat marked the quietude—an all-consuming stillness that betrayed her instincts more with each rising second. With a flick of her wrist, she squinted into the gathering gloom, scanning the edges of the grove for any sign of life. Her instincts cried out, a primal urge to flee, yet she forced herself to stand her ground. This was a search for answers, and she wouldn’t back down. But as the pendulum of tension swung on, she felt the pull of an inescapable draw toward the heart of the grove, far beyond the standing stones. That’s when the whispering began—a soft, caressing murmur that shifted through the air itself. Aurora felt it slide into her thoughts as if the grove were alive, willing her to listen. The words were indecipherable, a specter’s haunting lullaby woven with temptation. Reality
flickered
, and for a moment, the shadows deepened, swelling with the sound of barely audible laughter. It felt like the wildflowers
were laughing
at her, brilliant petals trembling in the night, their colors too vibrant for the darkness that surrounded her. She was
being beckoned
. Her pulse thundered as she edged deeper, the Heartstone
suddenly
hot against her skin, conspiring with her every instinct to draw her forward, to yield to whatever awaited her further in the shadows. A
solitary
figure
loomed
at the furthest edge of her vision, wreathed in darkness, far too still for the living. Just as she turned to face it fully, it vanished—dispersed into the night like a wisp of smoke, leaving only silence in its wake. Her breath hitched as panic threatened to consume her. Aurora could feel the
weight
of unseen eyes upon her, the sensation spiraling into a fierceness, urging her to
understand that this
was a realm where curiosity danced a dangerous tightrope with fear. A single heartbeat
echo
ed within the stillness of the Fae Grove, the
echo
whispering back unanswered questions that darted just out of reach. This wasn’t merely a search for answers; it was a reckoning with the shadows, a test of her resolve. She tightened her grip on the Heartstone and stepped forward, stepping through the veil of uncertainty enshrouding her, racing toward what lay within the depths of the grove.
