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.

The Raven’s Nest hummed low, a
comfortable
rumble of hushed conversations and clinking glasses.
Rory, fresh off a late
delivery, slipped through the green neon glow of the sign, the
chill
of the London night still clinging to her coat.
Silas, perched on his usual
stool behind the polished mahogany, offered a nod as she passed, his hazel eyes meeting hers for a
fleeting
moment before returning to the book open on the counter. She walked towards the back, where the low light softened the angular lines of old maps on the walls.
The air, thick with the
scent of aged whiskey and faint tobacco, wrapped around her, a
familiar
comfort.
A lone figure sat at
a corner table, back to the room, head bent.
Their straight, shoulder-length black hair
caught the dim light, mirroring the raven hues of her own.
A small, crescent-shaped scar, barely
visible on their left wrist, peeked out from under a rolled-up sleeve. Rory’s breath hitched.
Her hand instinctively went to
her own wrist,
tracing
the matching mark. The world outside the bar, the deliveries, the cold night, all faded.
Only the shape of the
head, the curve of the spine, the faint,
familiar
scent of lavender and something sharp, like ink, remained. As she drew closer, the figure shifted, looking up.
Bright blue eyes, startling against
a pale face, met hers. Her heart leaped, then plummeted, a stone dropping into a bottomless well. It wasn't a mirror. It was Laila. No, Aurora. No, Rory. The past,
fractured
and scattered,
suddenly
coalesced into a single, painful point. “Rory?”
The voice, quiet, hesitant, resonated
with a ghost of the past.
Her own name, spoken with
that particular
lilt
, felt like a tremor through the floorboards of her
carefully
constructed
present. “Laila?” Rory’s voice was a
whisper
, a question that held twenty-five years of answers. Or absence.
The name felt strange on
her tongue, an
echo
from a time she had buried deep. Aurora's lips curved, a slow, sad smile. “It’s Aurora now. Been for years.”
She gestured with a graceful
hand, palm up, towards the empty chair opposite her. “Please. Join me.” Rory sank into the chair, the worn
velvet
a soft contrast to the sudden hardness in her chest.
She studied Aurora, a stranger
and a reflection, all at once. The bright blue eyes were the same, but the spark, the fire that used to
dance
there, seemed dimmed, replaced by a quiet
intensity
. The straight black hair, once a wild halo framing a perpetually eager face, now lay sleek and contained.
Her clothes, a dark, impeccably
tailored suit,
seemed to
swallow the light, a
stark
contrast to the vibrant colors she remembered. “You look different,” Rory managed, the words tasting like dust. Aurora’s laugh was a soft exhalation of air, devoid of humor. “We all do, don’t we? Time, they say, marches on.” Her gaze swept over Rory, a meticulous assessment that made her
feel
suddenly
aware of her worn jeans and practical jacket. “You haven’t changed much, though. Still the same spirit, I imagine.” Rory bristled, a faint flush creeping up her neck. “Some things are hardwired.” “Indeed.” Aurora’s gaze drifted to the whiskey glass on the table. “Care for a drink? Silas makes a formidable Old Fashioned.” “Just water.” Rory still felt the phantom
weight
of her delivery bag. “Long night.” Aurora nodded, turning her head
slightly
, catching Silas’s eye.
He approached, his slight limp
more pronounced now that Rory noticed it.
He placed a glass of
water on the table, a silent acknowledgment to Rory, then looked at Aurora, a polite query in his hazel eyes. “Another for me, please, Silas.” Aurora’s voice was calm, almost detached. Silas gave her a discerning look, then moved back to the bar. “So.” Rory broke the quiet. “What brings you to this corner of London? Last I heard, you were… elsewhere.” The word
hung in the air
, weighted with
unspoken
questions. *Wales. Cardiff. Evan.* The memories were a tangle of thorns, sharp and painful. Aurora picked at a loose thread on her sleeve. “Business, mostly. A new project. London’s the hub, after all.”
She took a slow sip
of her whiskey when Silas returned, the amber liquid
glinting
in the low light. “And you? Still here, above the bar?” “It works.” Rory shrugged, a non-committal gesture. The truth was more complicated. The flat above Silas’s bar, a
sanctuary
from her past, a place where she could breathe. “Works for what, Rory?” Aurora’s tone was gentle, but the question
felt like a probe
. “You were always destined for more. Law school, remember? Your father’s legacy.” Rory’s hand tightened around her water glass. “Some legacies are best left unclaimed.” The memory of her father, Brendan Carter, pushing her towards a future she didn’t want, burned. “And some plans change. Life isn’t a straight path, Aurora.” Aurora’s eyes darkened, a shadow passing over them. “No, it isn’t. But sometimes, we just need a gentle push to see the way forward.” She looked around the bar, her gaze lingering on the black-and-white photographs on the wall, then returning to Rory. “You always had a fire, Rory. A strong
sense of
justice. It’s a shame to see it… dormant.” “Dormant?”
Rory scoffed, a genuine laugh escaping her
. “You think I’m dormant? I’m living, Aurora. I’m making my own way, on my own terms.” The words felt like a declaration, a desperate plea for her choices to be understood. “On your own terms, yes. But at what cost?” Aurora’s voice was soft, persuasive, a silken thread weaving its way into the conversation. “We had dreams, Rory. Big dreams, for how we’d change the world. What happened to those?” “Dreams shift. People change.” Rory glanced away, towards the hidden bookshelf that led to Silas’s secret room. A symbol of another life, another layer of her existence, that Aurora knew nothing about. “But some core truths remain.” Aurora leaned forward, her elbows on the table, her bright blue eyes fixed on Rory. “You were always the one with the sharp mind, the quick wit. The one who saw through the lies, who fought for the underdog. You still are, aren’t you?” Rory met her gaze, a
flicker
of something she couldn’t name—resentment, longing, a ghost of their shared past—passing between them. “What do you want, Aurora?” The question was blunt, cutting through the pleasantries and the
weight
of their history. Aurora smiled then, a genuine, if
fleeting
, smile that softened the edges of her face. “I want us to talk, Rory. Properly. After all these years.”
She paused, then added
, “And perhaps, to remind you of who you
truly
are.”
