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.

Aurora's fingers traced a lazy circle around the rim of her glass as she watched the amber liquid catch the dim light of The Raven's Nest. Tuesday nights were usually quiet, just the way she liked them. The usual evening crowd had thinned to a handful of patrons scattered across the bar—a couple in deep conversation at a corner table, a woman typing furiously on her laptop, and an older man nursing what
look
ed like his third whiskey. Behind the bar, Silas polished glasses with
methodical
precision, his movements economical despite the slight hitch in his stance when he shifted his
weight
to his left leg. The neon green sign outside cast an
ethereal
glow through the windows, painting strange shadows across the collection of maps and photographs that papered the walls. "Another?" Silas asked, nodding at her nearly empty glass. Aurora shook her head. "Early shift tomorrow. Yu-Fei's trying this breakfast deli
very
thing." Silas raised an eyebrow. "The Golden Empress serving breakfast? Times are changing." "Rent isn't," Aurora replied with a wry smile. The door swung open, letting in a gust of London drizzle and a tall figure who paused at the threshold, shaking water from a wool overcoat. Aurora didn't
look
up immediately; newcomers weren't unusual, even on slow nights. It was only when the figure approached the bar that something—the cadence of
footsteps
, perhaps—made her glance up. The glass nearly slipped from her fingers. "Max," she breathed. He was already
look
ing at her, as if he'd known exactly where she would be sitting. "Rory Carter," he said, his voice deeper than she remembered. Maximilian Hughes had been her closest friend through university—the boy with the wild ideas and wilder laugh who'd convinced her to skip lectures to see obscure bands, who'd stayed up all night helping her cram for exams she'd neglected. The Max who stood before her now wore a tailored suit that probably cost more than three months of her rent. His once shaggy blonde hair was cut short and neatly styled, but his eyes—those were still the same startling green that had always reminded her of sea glass. "What are you doing here?" she asked, too stunned to mask her surprise with pleasantries. Max gestured to the stool beside her. "Mind if I sit?" She nodded, unable to find words as he settled beside her, flagging Silas with practiced ease. "Macallan, neat," he ordered, then turned to face her fully. "I had a meeting nearby. Thought I'd stop in for a nightcap." "In Soho? What kind of law are you practicing these days?" The question came out more pointed than she'd intended. Something
flickered
across his face—surprise, perhaps, that she knew what he'd been doing since university. "Corporate. Mergers and acquisitions, mainly." He loosened his tie
slightly
. "I saw your father last month, actually. Cardiff Crown Court." Aurora's stomach tightened. "How is the illustrious Brendan Carter?" "Same as ever. Asked about you." She took a sip of her drink to avoid responding. Of course her father would run into Max. The universe had a cruel sense of humor that way. Silas placed Max's drink before him, his hazel eyes assessing the newcomer with the quiet scrutiny of someone who'd made a career of reading people. "Friend of Rory's?" he asked, his Welsh accent more pronounced than usual. "Old friend," Max replied, extending his hand. "Max Hughes." "Silas Blackwood. I own the place." They shook, and Aurora didn't miss how Silas' gaze lingered on Max's gold cufflinks before he moved away to serve another customer, giving them space while remaining within earshot. "So," Max said, turning back to her. "Deli
very
person? That's... unexpected." Aurora felt heat rise to her cheeks. "Part-time. It pays the bills while I figure things out." "I thought you'd be halfway through law school by now, following the family tradition." There was no judgment in his voice, just genuine curiosity, which somehow made it worse. "Plans change." She brushed her hair behind her ear, a nervous habit she'd never outgrown. "Not all of us had our lives mapped out at twenty." "Is that what you think?" Max laughed, but it lacked the easy warmth she remembered. "That I had it all figured out?" "Didn't you? Top of our class, straight to London School of Economics, then that internship at..." She faltered, realizing she was revealing how closely she'd followed his career despite their estrangement. "Hargrove & Bliss," he supplied. "And now junior partner at Whitman Stewart." He swirled his drink. "It
look
s good on paper, doesn't it?" Aurora studied him. Beneath the polished exterior, she caught glimpses of fatigue in the fine lines around his eyes, a tension in his shoulders that hadn't been there before. "Are you happy, Max?" The question hung between them, heavier than it had any right to be. He stared into his glass. "I'm successful." "That's not what I asked." Max's gaze met hers, and for a moment, the years between them
seemed to
dissolve.
"Remember that summer
after first year? When we talked about changing the world?" Aurora's chest tightened. That summer, they'd spent countless nights on the roof of her parents' garden shed, passing a bottle of cheap wine back and forth, plotting futures where they would right wrongs and make a difference. Before reality and expectations had pulled them in different directions. "We were kids," she said
softly
. "Were we wrong?" The question struck her like a physical blow. She absently rubbed the crescent-shaped scar on her left wrist—a remnant from when she'd fallen from that
very
shed at age twelve. "I don't know anymore." Max noticed the gesture, his eyes drawn to the pale mark. "You still have it. The scar from the great garden shed disaster." Despite herself, Aurora smiled. "Mum was convinced I'd need plastic surgery." "And you told her it gave you character." Max's smile mirrored hers, genuine this time. "You were always so stubborn." "Still am, according to most people who know me." A comfortable silence settled between them, filled with the soft clinking of glasses and murmured conversations around the bar. Through the window, the green neon light of The Raven's Nest's sign flashed intermittently, casting Max's face in an
otherworldly
glow that made him
look
alternately familiar and like a stranger. "I saw Eva last Christmas," Max said
suddenly
. "She mentioned you were in London. Said you left Cardiff rather... abruptly." Aurora tensed. The mention of her hasty departure from Cardiff—from Evan—was not something she had expected. "Did she tell you why?" Max's expression darkened. "Enough that I wish I'd been there." "It wouldn't have changed anything." Aurora traced the condensation on her glass. "Besides, you were gone by then. Off to bigger things." "Is that why you never called? Because you thought I was too busy with 'bigger things'?" The hurt in his voice was unmistakable, and Aurora felt
a pang of guilt
. "It wasn't that simple." "Then explain it to me." He leaned closer, his voice dropping. "Because one day we were inseparable, and the next, you wouldn't return my calls. Was it something I did?" "No," she said
quickly
, too
quickly
perhaps. "It was... e
very
thing was changing. You were heading to London, I was stuck in a program I hated, trying to please a father who was never going to be pleased. And then Evan happened, and by the time I got out, it felt like too much time had passed." "Five years isn't that long in the grand scheme of things," Max said quietly. "Long enough for you to become someone who wears cufflinks and orders expensive scotch," she replied, not unkindly. Max glanced down at his attire and chuckled. "Fair point. And long enough for you to become someone who lives above a bar in Soho and delivers Chinese food." "Don't forget the part where I'm a massive disappointment to my barrister father." "Are you, though?" Max's gaze
was searching
. "A disappointment to yourself, I mean. Not Brendan." Aurora considered the question. Was she disappointed in the turns her life had taken? There were regrets, certainly—the wasted years with Evan, the unfinished degree, the strained relationship with her parents. But since coming to London, since finding The Raven's Nest and the odd family that came with it, there had also been a kind of freedom she'd never known before. "I'm still figuring that out," she admitted. "But I'm not unhappy. Not anymore." Silas appeared, refilling Aurora's water glass without
being asked
. He gave Max an appraising
look
before moving away again, his limp
slightly
more pronounced as the night wore on. "He's protective of you," Max observed once Silas was out of earshot. "He gives me a place to stay and doesn't ask too many questions. It works for both of us." Max nodded, understanding dawning on his face. "You've built a life here." "I'm trying to," she said. "It's not the one I imagined, but it's mine." "I
envy that," Max
said so quietly she almost missed it. "The certainty." Aurora laughed. "Trust me, certainty is the last thing I feel most days." "At least you're living honestly." His fingers tapped a restless rhythm against his glass. "Do you know what I do all day? I help wealthy corporations become wealthier. I argue technicalities to protect people who don't deserve protection. And I'm good at it, which might be the worst part." The confession hung between them, raw and unexpected. Aurora reached out, her fingers brushing his wrist briefly before retreating. "It's not too late to change course." "Isn't it?" Max's expression was wistful. "Some choices feel irrevocable." "Says the man who once convinced me to change my entire dissertation topic two weeks before it was due." The memory brought a genuine smile to his face. "We didn't sleep for days." "But I got a first," she reminded him. "Because you believed I could do it." "I still believe in you, Rory," he said
softly
. "I never stopped." The words touched something deep within her, a tender spot she'd guarded
carefully
for years. "I missed you," she admitted. "More than I let myself acknowledge." Max's hand covered hers on the bar, warm and solid. "I'm sorry I didn't
look
for you sooner." "I'm sorry I disappeared." Outside, rain streaked the windows, blurring the lights of passing cars into watery trails of color. Inside The Raven's Nest, beneath maps of places they'd once dreamed of visiting together and photographs of strangers who'd seen more of the world than they had, Aurora and Max sat in a bubble of rediscovered connection,
navigating
the delicate space between who they had been and who they had become.
