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 nearly dropped her takeout container when she opened Eva's door and found Lucien Moreau standing in the hallway. His platinum hair was slicked back as immaculately as ever, and his mismatched eyes—one amber, one black—fixed on her with unnerving intensity. "Rory," he said, his French accent caressing her name in a way that still made something twist inside her chest. "I was expecting Eva." "Clearly." Aurora clutched the door frame, fighting the urge to slam it shut. "She's not here." Lucien leaned on his ivory-handled cane, and the familiar gesture sent a cascade of memories through her mind—his elegant fingers curled around that same handle as he'd guided her through the shadowy corners of London's supernatural underworld six months ago. "May I come in?" he asked, with that infuriating politeness he always maintained, even when the world was falling apart around them. "Why?" The question came out sharper than she intended. His heterochromatic gaze flicked past her, scanning the cramped flat with its towers of books and scrolls. "I have information. For Eva." A pause. "And for you." Aurora's fingers tightened on the doorframe. The last time Lucien had information "for her," she'd ended up running for her life through the back alleys of Hackney with demon ichor in her hair. But denying the half-demon entry might be more dangerous than letting him in. Lucien Moreau never forgot a slight. "Fine," she said, stepping aside. "But I was about to eat, and I'm not sharing." Lucien's lips quirked in that not-quite-smile she used to find so fascinating. He entered with his characteristic grace, the tap of his cane against the floorboards marking his progress into Eva's cluttered living space. He navigated around a stack of ancient grimoires, careful not to disturb them. "Still living on takeaway from the Golden Empress?" he asked, nodding at the container in her hand. Aurora set her food on the coffee table, annoyed that he remembered such a detail. "Yu-Fei gives me the employee discount. Some of us have to be economical." "Of course." He remained standing, though there was an empty chair nearby. Always maintaining the advantage of height. "How is your job at the restaurant?" "Cut the small talk, Lucien. What information is so important you had to deliver it in person?" Ptolemy, Eva's tabby cat, slinked into the room and immediately arched his back at the sight of Lucien, hissing softly. At least the cat had good judgment. Lucien sighed, twisting the handle of his cane. Aurora knew what lay inside it—a thin, deadly blade that had saved both their lives more than once. "Your ex-boyfriend is looking for you." Aurora froze. "Evan?" "Yes. But it's more complicated than a simple case of a jealous ex." Lucien finally sat, perching on the edge of Eva's reading chair. "He's being manipulated by something... supernatural." The curry in Aurora's stomach turned to ice. "That's impossible. Evan's as mundane as they come. He doesn't even believe in horoscopes, let alone demons." "That's precisely what makes him an ideal puppet." Lucien's mismatched eyes fixed on her, and she remembered how those eyes had looked in the darkness of his car six months ago, when he'd leaned across the center console and— She cut the memory off. "What would want to use him?" "Something that wants to get to you." Lucien set his cane across his knees. "You've made quite a name for yourself since our... association, Rory. The human who helped take down the Crimson Court has enemies." Aurora sank onto the couch, her appetite gone. The small crescent scar on her left wrist—a childhood injury long before all this supernatural madness—tingled as it always did when she was stressed. "I thought I was done with all that." "Nobody is ever done with the supernatural once they've caught its attention." His voice softened. "I warned you about that, if you recall." She did recall. She recalled everything about the night he'd warned her—the rain on the windows of his expensive car, the smell of his cologne, the way his hand had felt against her cheek before she'd pulled away and told him that their arrangement was over. "So what now? I find a new city? Change my name again?" She meant it to sound flippant, but her voice broke on the last word. Lucien's expression changed, almost imperceptibly. "No. You let me help you." Aurora laughed, a brittle sound. "Like last time? When you decided that the best way to protect me was to keep me completely in the dark about your plans?" "I was trying to—" "Save me. Yes, I know. You made that abundantly clear." She stood up, pacing between the stacks of Eva's research. "But you didn't trust me enough to let me make my own choices." Lucien rose too, his height making the small flat seem even more cramped. "You were new to all of this. You had no idea what you were facing." "So you lied to me." "I omitted certain truths." "That's just a fancy way of saying you lied." Aurora stopped pacing and faced him directly. "You sent me to that warehouse knowing it was a trap." "A controlled trap," he countered, taking a step toward her. "With safeguards you knew nothing about." "Safeguards that nearly failed." She unconsciously touched her side where a thin scar still marked where a Crimson Court blade had sliced through her jacket. "I could have died, Lucien." "But you didn't." His voice dropped. "Because despite what you think, I never intended for you to face any real danger." They were standing too close now, the air between them charged with months of unspoken words. Aurora could smell his familiar cologne—something expensive and subtle, with notes of amber and sandalwood. "You still used me as bait," she whispered. "And you still walked away when it was over." His accent thickened as it always did when his emotions ran high. "Without letting me explain." Aurora looked away first, her gaze falling on Ptolemy, who had settled into a suspicious crouch, watching them. "What's different now?" she finally asked. "Why should I trust you this time?" Lucien's hand moved, almost reaching for her before he stopped himself. "Because this time, I'm telling you everything from the start. Because I've spent the past six months regretting how things ended between us." His voice was soft but steady. "And because whatever's controlling Evan knows about your connection to me, and it's using that knowledge." Aurora's head snapped up. "What do you mean?" "Evan was seen at The Veil last night, asking questions about me. About us." The Veil was a club that catered to supernatural beings—a place where Lucien had first introduced her to London's hidden world. A place where they'd danced, once, his hand warm at the small of her back. "How would Evan even know about The Veil? About you?" "That's what concerns me." Lucien's fingers tightened on the ivory handle of his cane. "Someone is feeding him information. Someone who knows about our... history." Aurora wrapped her arms around herself. "We don't have a history. We had a few weeks of you showing me around supernatural London because you needed a human connection for that case, and then it ended." "Is that really all it was to you?" His mismatched eyes searched hers, and for a moment, the cool, controlled fixer slipped away, revealing something raw underneath. Aurora remembered their last kiss—desperate and heated against the wall of his Mayfair apartment, before everything had fallen apart. Before she'd discovered his deception. Before she'd grabbed her coat and walked out into the rain, ignoring his calls to wait, to let him explain. "It doesn't matter what it was," she said finally. "It's over." "Yet here I am," Lucien replied, "and here you are, still in danger because of your association with me." Aurora sank back onto the couch, suddenly exhausted. "So what do you suggest? Since you obviously have a plan." He nodded, slipping back into business mode, though his eyes never lost that intensity. "We need to find out what's controlling Evan before he finds you. I have resources, contacts who specialize in identifying supernatural influences." "And what do you need from me?" "Information about Evan. His habits, his weaknesses. And..." He hesitated. "I need you to work with me. Closely." The implication hung in the air between them. "For how long?" "Until we neutralize the threat." Lucien took a seat beside her on the couch, careful to maintain a respectful distance. "I'm not asking you to forgive me, Rory. I'm asking you to trust me one more time, because your life may depend on it." Aurora studied him—the perfect cut of his charcoal suit, the precise angle of his platinum hair, the subtle tension in his shoulders that most people would never notice. She'd spent enough time with Lucien Moreau to know when he was genuinely worried. "Alright," she said finally. "But this time, no secrets. No 'omitting certain truths' for my protection. If we do this, we're partners." Something flashed in his mismatched eyes—relief, perhaps, or something deeper. "Partners," he agreed, offering his hand. Aurora hesitated for just a moment before taking it. His skin was warm against hers, sending an unwelcome tingle up her arm that she'd spent six months trying to forget. "Partners," she echoed, withdrawing her hand quickly. "Now tell me everything you know about what's happening with Evan." As Lucien began to explain, Aurora couldn't help noticing how easily they fell back into their old rhythm, finishing each other's thoughts, building on each other's ideas. Whatever had broken between them six months ago, some connections remained intact—whether she wanted them to or not.
