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.

The Raven's Nest hummed with the low murmur of conversation, the clinking of glasses, and the soft strains of a jazz quartet playing from a corner stage. The dim lighting cast a warm glow over the patrons, who huddled in booths or leaned against the polished mahogany bar. The walls, adorned with old maps and black-and-white photographs, whispered stories of distant lands and forgotten times. Aurora Carter, known to most as Rory, slipped through the entrance beneath the distinctive green neon sign. She paused, letting her eyes adjust to the dimness, and scanned the room. Her bright blue eyes, sharp and discerning, took in the familiar scene. It was a place she knew well, a refuge above which she lived, and yet tonight it felt different, as if the air itself was charged with something
unspoken
. She made her way to the bar, her straight shoulder-length black hair swaying with each step. Silas Blackwood, the bar's owner and her landlord, stood behind the counter, his grey-streaked auburn hair catching the light. He moved with a slight limp, a reminder of his past life, but his presence was as commanding as ever. He nodded to Rory as she approached, a silent acknowledgment of their shared history. "Evening, Rory," Silas greeted, his voice a gravelly rumble that carried the
weight
of years and secrets. He polished a glass with a practiced hand, his silver signet ring
glinting
in the low light. "Evening, Silas," Rory replied, sliding onto a barstool. "Busy night." "Always is when the weather turns," he said, gesturing to the rain-slicked streets outside. "What'll it be?" "Just a ginger ale, thanks," she said, offering a small smile. She wasn't here for the drinks tonight, but for the
solace
the place offered. As Silas turned to fetch her drink, Rory's gaze drifted across the room. Her eyes landed on a figure seated alone at a corner table, partially obscured by shadow. Something about the way the person sat, the tilt of their head, stirred a memory she couldn't quite place. Silas returned with her drink, setting it before her with a nod. "You look like you've seen a ghost," he remarked, following her gaze. "Maybe I have," Rory murmured, her curiosity piqued. She took a sip of her drink, the ginger ale crisp and refreshing, and considered her next move. The figure in the corner shifted, leaning forward into the light. Rory's breath caught in her throat as recognition dawned. It was Eva, her childhood friend, the one who had coaxed her to London all those years ago. But the woman before her was not the Eva she remembered. Her once vibrant auburn hair was now a muted chestnut, and her eyes, once full of mischief, held a shadow of something Rory couldn't quite name. Rory hesitated, the
weight
of
unspoken
years pressing down on her. She and Eva had been inseparable once, but time and circumstance had pulled them apart. She wondered what had brought Eva here, to this place, on this night. Gathering her resolve, Rory slid off the barstool and made her way to the corner table. Eva looked up as she approached, her expression shifting from surprise to something softer, a
flicker
of the old warmth. "Rory," Eva said, her voice a blend of disbelief and relief. "I can't believe it's you." "Eva," Rory replied, her own voice
tinged
with emotion. "It's been too long." Eva gestured to the empty chair across from her. "Join me?" Rory nodded, taking the seat. For a moment, they sat in silence, the years stretching between them like a chasm. Rory studied Eva, noting the changes time had wrought. There was a new hardness to her features, a guardedness that hadn't been there before. "You look well," Rory ventured, breaking the silence. Eva smiled, a small, rueful curve of her lips. "I suppose I do, on the surface. But you know how it is." Rory nodded, understanding the
unspoken
words. Life had a way of leaving its mark, visible or not. "What brings you to the Nest?" Eva hesitated, her fingers tracing the rim of her glass. "I was in the neighborhood," she said finally, though Rory sensed there was more to it. "And I heard this place was... interesting." Rory chuckled
softly
. "That's one way to put it. Silas runs a tight ship, but there's always something happening here." Eva's gaze
flicked
to Silas, who
was engaged
in conversation with another patron. "He seems... formidable." "He is," Rory agreed. "But he's good people." They lapsed into silence again, the
weight
of
unspoken
questions hanging between them. Rory wanted to ask about the years they'd missed, about the paths that had led them here, but she hesitated, unsure of how to bridge the gap. Eva
seemed to
sense her hesitation. "I heard about Evan," she said
gently
, her eyes meeting Rory's. "I'm sorry." Rory's hand unconsciously brushed the small crescent-shaped scar on her left wrist, a reminder of a past she'd rather forget. "It's in the past," she said, though the words felt hollow. "I'm... I'm okay now." Eva nodded, her expression one of understanding. "I wish I'd been there for you," she said
softly
. "But I had my own mess to deal with." Rory looked at her friend, seeing the
echoes
of shared history in her eyes. "We both did," she acknowledged. "But we're here now." Eva smiled, a genuine warmth breaking through the shadows. "Yes, we are." They talked then, the conversation flowing more easily as they shared stories of their lives, the triumphs and the struggles. Rory spoke of her work at the Golden Empress, of the small victories and the challenges of starting anew. Eva listened, her interest genuine, and in turn, she shared her own journey, the twists and turns that had brought her back to London. As the night wore on, the tension between who they were and who they'd become
began to
ease. The years that had separated them
seemed to
melt away, leaving behind the essence of their friendship, resilient and enduring. Eventually, the bar
began to
empty, the patrons drifting out into the rain-soaked streets. Silas moved through the room, extinguishing candles and tidying up, his presence a comforting constant. Rory and Eva lingered at their table, reluctant to part ways. "We should do this again," Rory said, a hopeful note in her voice. Eva nodded, her eyes bright with promise. "I'd like that." They stood, and Rory pulled Eva into a hug, the embrace a reaffirmation of their bond. "Take care of yourself," Rory said as they parted. "You too," Eva replied, her smile lingering as she turned to leave. Rory watched her go, a sense of peace settling over her. The past was a
tapestry
of moments, some painful, some joyous, but it was the present that mattered now. She returned to the bar, where Silas
was waiting
with a knowing look. "Old friend?" he asked, his hazel eyes warm with understanding. "Yeah," Rory said, a smile playing on her lips. "An old friend." Silas nodded, his expression one of approval. "Good to see you reconnecting." Rory took a deep breath, feeling lighter than she had in years. "It is," she agreed, grateful for the unexpected encounter that had brought a piece of her past back into her life. As she made her way to the door, the rain still falling
softly
outside, Rory felt a renewed sense of hope. The future was uncertain, but she knew she wouldn't face it alone. And that, she realized, was enough.
