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 was a
sanctuary
of shadows and whispers, a place where secrets felt at home. The green neon sign buzzed faintly above the entrance, casting an eerie glow on the cobblestone street below. Inside, the dim lighting and the scent of aged whiskey created an atmosphere that was both inviting and
foreboding
. Old maps and black-and-white photographs adorned the walls, each telling a story of a world long past. Aurora Carter, known to her friends as Rory, pushed open the heavy wooden door and stepped inside. The familiar creak of the floorboards beneath her feet brought a small, nostalgic smile to her lips. She had spent many nights here, seeking
solace
in the dim corners of the bar. Tonight, she was here for a different reason. She needed to speak with Silas. Silas Blackwood stood behind the bar, his grey-streaked auburn hair catching the low light. He moved with a slight limp, a reminder of a life lived on the edge. His hazel eyes, sharp and observant,
flicked
up as Rory approached. "Rory," he greeted, his voice a low rumble. "It's been a while." "Too long, Si," she replied, sliding onto a barstool. "How's the knee?" "Still creaky, but it gets me where I need to go," he said with a wry smile. "What brings you here tonight?" "Just needed a familiar face," she said, her eyes scanning the room. "And maybe a drink." Silas nodded and poured her a glass of whiskey, sliding it across the bar. "On the house." "Thanks," she said, taking a sip. The warmth of the liquor spread through her, easing some of the tension in her shoulders. "How's business?" "Steady," he replied. "The usual crowd. Though we did have a bit of excitement last week. Some bloke tried to start a fight. Didn't end well for him." Rory chuckled. "I can imagine. You always did have a way of handling trouble." Silas's eyes softened. "And you always had a way of finding it." Before Rory could respond, the door to the bar creaked open again. She turned, her breath catching in her throat as she saw who had entered. It was Eva, her childhood friend, the one who had convinced her to flee to London all those years ago. But Eva looked different now. Her once vibrant red hair was now a muted auburn, and there was a hardness in her eyes that hadn't been there before. "Eva?" Rory said, her voice
barely above a whisper
. Eva's
eyes widened
in surprise. "Rory? Is that
really
you?" "It's me," Rory said, standing up. "It's been a long time." Eva approached
slowly
, as if unsure whether to believe her eyes. "I can't believe it. I thought you were still in Cardiff." "I left," Rory said, her voice
tinged
with regret. "I had to get away." Eva nodded, her expression
unreadable
. "I understand. I just... I didn't expect to see you here." "Neither did I," Rory admitted. "What brings you to The Raven's Nest?" Eva glanced around the bar, her eyes lingering on Silas for a moment before returning to Rory. "I was looking for someone. But it seems I've found someone else instead." Rory gestured to the barstool beside her. "Sit. Let's catch up." Eva hesitated for a moment before taking the seat. Silas, sensing the need for privacy, moved to the other end of the bar, giving them space. "So," Rory began, unsure of where to start. "How have you been?" Eva sighed, running a hand through her hair. "It's been... complicated. After you left, things changed. I changed." Rory nodded, understanding all too well. "I know the feeling." They sat in silence for a moment,
the weight of unspoken words
hanging between them. Finally, Eva broke the silence. "Do you remember the last time we saw each other?" she asked, her voice
barely above a whisper
. Rory nodded, her throat tight. "How could I forget? It was the night I left Cardiff. You told me to run, to get away from Evan." Eva's eyes softened. "I was so scared for you. I didn't know what else to do." "You did the right thing," Rory said, reaching out to squeeze Eva's hand. "You saved me." Eva looked down at their joined hands, her eyes
glistening
with unshed tears. "I just wish I could have done more." "You did enough," Rory said firmly. "More than enough." Eva took a deep breath, composing herself. "What about you? How have you been?" Rory shrugged, a small smile playing on her lips. "I've been getting by. Working part-time at a restaurant, living above Silas's bar. It's not glamorous, but it's a life." Eva nodded, a hint of a smile on her lips. "I'm glad you're safe." They fell into a comfortable silence, the years of separation
slowly
melting away. It was as if no time had passed at all, and yet, everything had changed. "Do you ever think about going back?" Eva asked
suddenly
, her eyes searching Rory's. Rory shook her head. "Cardiff isn't home anymore. London is. Besides, there's nothing for me there." Eva nodded, understanding. "I feel the same way. I've been moving around a lot, trying to find my place." "Have you found it?" Rory asked
gently
. Eva sighed. "Not yet. But I'm getting closer." Rory smiled. "That's all we can do, isn't it? Keep moving forward, one step at a time." Eva returned the smile, a sense of peace settling over her. "Yeah. One step at a time." They sat together, the
weight
of the past
slowly
lifting. There were still scars, still wounds that hadn't fully healed, but they were together again. And that was enough. Silas returned, his presence a comforting anchor. "Everything alright here?" he asked, his eyes flicking between the two women. Rory nodded. "Yeah, Si. Everything's alright." Eva looked at Silas, a hint of curiosity in her eyes. "You must be Silas. Rory's told me about you." Silas smiled, his eyes crinkling at the corners. "All good things, I hope." Eva chuckled. "Mostly." Silas laughed, a deep, rumbling sound. "I'll take it." Rory looked at her two friends, a sense of contentment washing over her. For the first time in a long time, she felt at peace. The Raven's Nest had always been a place of refuge, a place where she could find herself. And now, it was a place where she could reconnect with the people who mattered most. As the night wore on, the three of them talked and laughed, sharing stories and memories. The
weight
of time and
unspoken
regret
slowly
faded, replaced by
a sense of hope
and possibility. They had all changed, but in the end, they were still the same. And that was enough. The green neon sign outside buzzed
softly
, casting its glow on the cobblestone street. Inside, the warmth of friendship and the promise of new beginnings filled the air. The Raven's Nest was more than just a bar; it was a home. And for Rory, Eva, and Silas, it was a place where they could find their way back to each other, one step at a time.
