System
You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

Aurora’s motorbike sputtered, coughed, and
died, leaving her stranded in the
oppressive
silence
of Richmond Park.
Headlights, two feeble beams, cut
through the inky blackness, revealing only the immediate stretch of winding tarmac. No streetlights illuminated the drive.
She had been sure she’d
had enough fuel to make it to the grove.
The air, heavy with the
scent of damp earth and unseen blossoms, clung to her. She checked her
watch
. Ten minutes past midnight. The note had been explicit: *Midnight. The Fae Grove. Don’t be late.* The words, scrawled in an unfamiliar hand, had offered no explanation, no hint of the sender. Only the command. A shiver
traced
her spine, unrelated to the surprising
chill
of the late spring night.
Rory dismounted, the soft crunch
of her boots on gravel
echoing
loudly in the stillness.
A quick kick of the
starter, a hopeful twist of the throttle — nothing. The engine remained stubbornly silent.
Her phone, pulled from her
pocket, displayed a single bar of signal, then two, then none. The screen went dark. Wonderful.
She gripped the handlebars, her
knuckles white.
Another deep breath, a slow
release.
She scanned the dense line
of ancient oaks bordering the road, trying to recall her directions.
The grove entrance, if memory
served, lay beyond the cluster of standing stones, a landmark she now realized
was hidden
by the impenetrable darkness. She sighed.
No choice but
to walk.
The Heartstone Pendant, a deep
crimson against her skin,
pulsed
faintly, a soft
warmth
spreading outward.
It always did that when
something was… off. Not dangerous, usually, just *
different
*. Tonight, the
pulse
felt stronger, a steady beat against her collarbone.
Not quite a warning, more an affirmation of the abnormal
. Rory started down the deserted road, her
footsteps
the only sound disturbing the nocturnal calm. The trees
loomed
, their branches like skeletal fingers reaching into the void. The ground beneath her boots was softer now, the tarmac giving way to a grassy track.
She pulled her leather jacket
tighter, more for comfort than
warmth
, the
familiar
scent of old leather a small anchor. The air grew heavier, thick with an almost cloying sweetness, like honey and night-blooming jasmine. It made her head swim, a dizzying effect that cleared the moment she focused on it. The track narrowed, eventually disappearing altogether, replaced by a carpet of moss and fallen leaves. The trees here grew closer together, their ancient trunks gnarled and twisted, forming a kind of arboreal tunnel. The faint starlight that had pierced the canopy vanished. Deep black swallowed her.
She fumbled for the small
tactical flashlight on her belt. The beam, a narrow spear, cut through the
gloom
. It revealed massive, rough-hewn stones, almost swallowed by ivy and moss, standing shoulder to shoulder in a rough circle. The standing stones. She had found it. The entrance to the Fae Grove. A gust of wind, sudden and cold, rustled through the invisible leaves overhead.
It carried a sound, thin
and reedy, like a forgotten flute. Or a
whisper
. Rory froze, her flashlight beam sweeping through the darkness beyond the stones. Nothing moved. The sound faded, leaving behind the heavy
silence
.
Her heart hammered against her
ribs, a frantic drum in her chest.
She stepped between two of
the massive stones. The transition was unsettling. The air inside the grove was markedly
different
, warmer, almost humid, and the sweetness intensified. Wildflowers, impossibly vibrant, bloomed in the partial light of an unseen moon, their colours a blur of crimson and sapphire in the dimness. They shouldn’t have been there, not in this weather, not at this time of year. The path, if it could be called that, was a narrow trace through knee-high grass and ferns.
She followed it, the Heartstone
a persistent
warmth
against her skin. The further she went, the more the trees
seemed to
press in, their branches weaving together overhead, forming a dense, living ceiling. Stars, even the few that had been visible before, vanished
completely
. A soft thud sounded behind her. Rory spun, flashlight beam cutting through the shadows. A small branch, no thicker than her finger, lay on the ground.
It hadn't been there a
second ago. Had it fallen? A small breeze, barely a breath, whispered past her ear.
It carried the scent of
wet earth and something else, something musky and strangely animalistic. She continued, her pace quickening. The air grew still, the
silence
profound
, almost suffocating. The only sounds were her own ragged breaths and the crunch of her boots on the leafy ground. Then, a rustle. Not the wind this time.
It came from the dense
undergrowth to her right, a distinct movement, like something large sliding through the ferns. Rory stopped, her hand instinctively going to the small knife she kept in her boot. She didn't draw it. Not yet. Her bright blue eyes darted into the shadows. Nothing. The rustling ceased. She waited, every nerve ending alert, straining to hear over the roar of her own blood in her ears. A shadow detached itself from the deeper darkness at the edge of her vision, a
fleeting
, undefined shape. It moved low to the ground, too fast to properly register. Her flashlight beam whipped towards it, but it
was gone
, swallowed by the
oppressive
gloom
. Her breath hitched. She was not alone. The certainty settled over her like a shroud. A low, guttural growl rumbled through the air, vibrating in her chest. It wasn't human. It came from all directions, surrounding her, pressing in from the darkness. Her grip on the flashlight tightened. The beam
wavered
. She
could feel
eyes on her now, a cold, hungry gaze from the unseen. The Heartstone
throbbed
, a steady, insistent beat against her skin. It was no longer a gentle
warmth
, but a
searing
heat. A warning. She backed away
slowly
, her eyes
scanning
the impenetrable wall of trees. The growl intensified, a chorus of unseen throats. The sweetness in the air turned sickly, cloying. A twig snapped behind her. Rory whirled, flashlight beam cutting through the darkness. Nothing. But the feeling of being watched intensified, a malevolent presence pressing in closer, its breath, cold and stale, brushing against her neck. She spun again, panic rising like bile in her throat. She needed to get out. Now. The way back, however, had disappeared. The path, once faintly visible,
was gone
, swallowed by the encroaching flora. Trees, thick and unyielding, formed an impenetrable barrier in every direction. The wildflowers bloomed brighter now, their unnatural hues glowing faintly in the deepening darkness. A high-pitched shriek tore through the
silence
, raw and
chilling
, too close for comfort. It
echoed
through the grove, impossibly loud, before fading into a guttural chuckle. The sound, undeniably,
was laughing
at her.
