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.

Write the scene from the moment the door opens. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary.

Rory's heart pounded as she gripped the doorknob, hesitating. She hadn't seen Lucien in nearly a year, not since that night when everything fell apart. Taking a deep breath, she pulled the door open. There he stood, platinum hair
gleaming
under the dim hallway light, his striking heterochromatic eyes narrowing as they met hers. Rory felt a flutter in her chest — she'd forgotten just how devastatingly handsome he was. "Lucien," she breathed,
barely above a whisper
. "What are you... how did you—" "May I come in, Rory?" he interrupted, his low voice sending a shiver down her spine. There was an undercurrent of something in his tone —
tightly
controlled emotion, perhaps. Or was it simply an
echo
of the hurt she'd caused him? Rory hesitated for the briefest moment before stepping aside, allowing him to enter. As Lucien strode past her, the familiar scent of his cologne — crisp and woodsy — enveloped her, stirring up a swirl of memories. She closed the door, her fingers trembling
slightly
. "To what do I owe this unexpected visit?" Rory asked, turning to face him. Eva's flat was in its usual state of disarray, papers and books scattered everywhere, Ptolemy the cat curled up on the sofa. She felt
suddenly
self-conscious, wishing she'd tidied up a bit. Lucien's gaze swept over the cluttered space before settling on her. "I need your help," he said simply, his eyes searching her face. Rory blinked, caught off guard. After everything, she'd never expected him to seek her out, let alone ask for her assistance. "My help?" she
echo
ed. "With what?" "A delicate... situation has arisen." Lucien's mouth tightened into a grim line. "One that requires discretion and a certain set of skills. I've exhausted my other options, and you're the only one I can trust with this." Trust. The word
hung in the air
between them, laden with
unspoken
history. Rory felt
a pang of guilt
, remembering how she'd shattered that trust all those months ago. "I see." She chewed her lower lip, considering. "What kind of situation are we talking about?" Lucien's eyes darkened. "Something that threatens the balance between our world and the demonic realm." Rory's
eyes widened
. "Demons?" She ran a hand through her hair, processing this. "What could you possibly need my help with regarding demons?" "It's a long story," Lucien said, his gaze shifting away. "One I'd rather not get into the details of here." He took a step closer, his expression intense. "Will you help me, Rory?" Rory felt the air growing thick with tension as they stood there, mere feet apart. She could see the strain
etched
on Lucien's face, the subtle vulnerability beneath his usual cool demeanor. Despite the hurt and confusion of their last encounter, she knew she couldn't turn him away, not when the stakes were so high. "Yes," she heard herself say, the word leaving her lips before she could fully consider the ramifications. "Of course I'll help you, Lucien." Relief
flickered
across his features, only to be
quickly
replaced by a guarded look. "Thank you," he said, his voice low. He glanced around the flat once more. "When can we leave?" Rory blinked, taken aback by his urgency. "Leave? Leave for where, exactly?" "My flat," Lucien replied. "I have intel and resources there that will be crucial for this task." He paused, his expression softening
ever so slightly
. "And it's... safer than this place." Rory understood the
unspoken
implication — Eva's flat, with its limited security, was too vulnerable. And if demons were involved, Lucien was right to be concerned. She nodded
slowly
. "All right, then," she said, turning to gather her things. As she slipped on her jacket and grabbed her keys, Rory couldn't help but steal a glance at Lucien. He stood there, ramrod straight, his hands clasped around the ivory handle of his cane. She caught the faint lines of tension in his jaw, a
stark
contrast to his usual composed demeanor. Rory's heart ached with the realization that despite the awkwardness and unresolved issues between them, Lucien still trusted her enough to bring her into this perilous situation. It was a
testament
to the bond they'd once shared, a bond that, try as she might, she could never fully sever. Leading the way out of the flat, Rory felt Lucien's presence close behind her, the familiar scent of his cologne enveloping her once more. As they descended the stairs, she
couldn't help but wonder
what exactly they were about to get themselves into — and whether it would be the catalyst to finally confront the ghosts of their past.
