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 knuckles ached from twisting the third deadbolt, but she didn’t dare leave the door half-closed. The hallway beyond Eva’s flat smelled of curry and damp brick, the muted hum of the restaurant’s neon sign pulsing through the drywall. A single knock had sounded only moments ago—light, insistent—and now the corridor lay hushed, as though waiting for her to finish deciding whether to open or bolt the door back in place. She pressed her palm flat against the wood, tracing the line of the crescent-shaped scar on her left wrist as if it might steer her choice. Ptolemy, Eva’s old tabby, twined around her ankles, yowling softly. His fur bristled; he sensed her tension. She swallowed back the urge to flee. There were times when flight felt safer than confrontation, but not tonight. She slid the bolt free and cracked the door just enough to slip an eye through. A figure filled the gap: tall, impeccably dressed in a charcoal suit that hugged lean shoulders, platinum hair slicked back so that every strand caught the dull hallway light. One eye glittered amber, the other a liquid black. The ivory handle of a cane peeked from his right hand, carved with an ornate swirl. “Aurora,” he said, voice smooth as silk over gravel. “May I come in?” She inhaled, tasting smoke and curry, fear and something sharper—anger, maybe. “Lucien,” she rasped, letting the name hang like a challenge. “You’re trespassing.” He dipped his head in a faint bow. “I was invited.” “Did Eva send you?” The question stumbled out. She didn’t wait for an answer. With a gentle push, she unlatched the second bolt. “One step farther and I’ll call her.” He let her draw the chain, then stopped, hands folded calmly against his torso. “I don’t want trouble,” he said, voice almost contrite. “I need your help.” Ptolemy hissed, arcing his back. Rory’s heart pitched in her chest. He straightened, as if summoned by her thundering pulse. “Stay back,” she warned, stepping aside to reveal the jumble of books, scrolls, and research notes that crowded the hallway. Her sanctuary, overturned. He ducked beneath the chain and into the narrow corridor. The door sighed as it closed behind him, and she hurried to slide the chain back in place. The click of metal making it feel so final, so closing of yet another door. “Why are you here, Lucien?” she asked, pressing her back against the chipped paint of her hallway wall. The plaster felt cold against her spine. His heterochromatic gaze roamed over the stacks of open tomes. “You’ve been researching the Avaros Codex,” he said. “I know because—” he lifted one finely gloved hand and settled his fingers on the edge of an ancient scroll, “—you’ve been sloppy. The glyphs on this page are smudged from coffee drips.” She exhaled, the sharp edge of her anger curdling into something tighter. “If you’ve been watching me, then you’re trespassing with surveillance.” He dropped his hand like a wounded bird and took a slow step back. “I wasn’t watching you,” he lied smoothly, and she watched the shape of his jaw clench beneath the starlight from the streetlamp’s half-shattered glass. “I was watching the council’s movements. They’re coming for it, Rory. The Codex.” She blinked. “The council?” He nodded, shifting the cane’s weight. “The Tribunal of London. They want to suppress every tear between our world and Avaros. You know what they do to anyone who meddles.” His amber eye glimmered with warning. “What you’re doing could cost lives.” Her throat went dry. “Then tell me why you didn’t warn me before—” “Because I was on assignment.” He glanced away, and for a moment Rory saw the boy he might once have been, before the demon blood hardened him. “I couldn’t risk it.” Her pulse pounded. She thought of the night he’d vanished, leaving a single ivory cane by her doorstep, no word, no warning. She thought of her phone, unanswered calls, nights she’d lain curled around her own fear. “You left me,” she said. The words cut through the air, jagged shards of accusation. “You left me when I needed you most.” He closed his eyes. One amber, one black lid folding in on itself. “I’m sorry.” It came so quietly she might have imagined it. Then he opened his eyes, and something fragile cracked in them. “I was bound by duty. You know what my father expects of me.” She pressed her hand to her wrist, feeling the scar throb beneath her palm. “We had an agreement.” He drew in a breath, unsteady. “I know.” He kept his gaze low, his shoulders stooped. “But if I end up here now, it’s because the Tribunal has noticed. They’ll seize the Codex tonight. If we don’t move it—if we don’t protect it now—it disappears forever.” Her pulse slowed, reason beginning to thread itself through the jumble of emotion. The Codex had become her obsession—pages of demon-sprung incantations, forbidden spells clawing at the borders between worlds. She’d thought she had time. But Lucien—this impeccably dressed, half-demon stranger—had just reshaped everything by walking through her door. She found her voice on a tremor. “Then tell me what you want.” He straightened, returning a measure of his old command. “I want to work with you. Tonight. To hide it in a place the Tribunal won’t touch. You know London’s veins better than anyone.” He gave a crooked half-smile, the side-lit angles of his face suddenly beautiful despite himself. “And I… I need you.” Her heart stumbled at the words, so soft, so honest. She looked at the books scattered across the dusty floor, at the commentary drooping from small wooden shelves. This was her world. And now he was here, bridging two halves in her chest: the scholar, the runaway, the woman who could knock him out if he overstepped. She could feel the pull between them, old and unbroken. She folded her arms. “Why should I trust you again?” He lifted his cane with slow deliberation, tapping it once against the floor. Ptolemy skidded across the boards, hissing. Lucien held out the ivory handle. “Because I carry something they don’t know I have.” He slipped a hidden latch in the grip. The blade slid free with a soft whisper. “And because I’d rather take a knife to the throat than steal your trust again.” She stared at the shining steel. Then at Lucien’s face, so starkly illuminated in the corridor’s dim glow. Her shoulders sagged. Years of hurt and hope tangled together—tighter than any deadbolt. She exhaled and unlatched the chain. The metal dropped like a confession. He sheathed the blade. “Thank you.” She crossed her arms again, but the tremor in her voice betrayed her. “Tell me everything. And if you lie—” “I won’t,” he said. His amber eye flickered, just a flash, as if stolen by candlelight. “I promise.” She opened the door the rest of the way and stepped aside, allowing him into her world. The flat was smaller than she remembered, suffocating with dusty tomes and half-finished research. She heard the curry house burner click beneath her feet and felt the pulse of Brick Lane’s life outside. He paused at the threshold, lifting one gloved hand as if to touch her again, but he didn’t. Instead he surveyed the chaos—papers pinned to the walls in sketched glyphs, open volumes piled in towers. “You’ve done well,” he said, voice soft. “But not well enough.” She folded her arms again, scanning his face for the flicker of guile. She found nothing but that same tortured sincerity. Her heart, bruised and hollow, squeezed against her ribs. Then she nodded once, sharply, as though granting herself permission. Lucien moved closer, cane tucked under one arm. He knelt and gathered a small stack of books, laying them on the narrow table by the window. “First,” he said, “we relocate the Codex to a safehouse. Then we disguise the sigils.” He tapped the open spine of a volume thicker than his arm. “You know what has to be done.” She swallowed, steadying her breath. She reached up and brushed a lock of her straight, shoulder-length black hair behind her ear. “Then let’s begin.” He looked up at her, and for a heartbeat the world narrowed to the amber of one eye, the black of the other, and the unspoken promise that flickered between them. Then he offered his hand—gloved, steady—and she took it. Together they turned toward Eva’s cramped living room, toward the scattered scrolls, toward the uncertain night ahead. And though the hallway door remained slightly ajar behind them, it felt as if they had already closed another, more fragile barrier—one of silence and regret—and stepped into something altogether new.
