“The Conservatory,” Cosima ground out, her voice raw. She scooped Nico into her arms, ignoring the fresh wave of black fluid that stained her tunic. His small body felt weightless as dry kindling, an agonizing reminder of how little time remained. “He needs the antitoxin. Now.” Bastian watched her, his own face a mask of calculated fury. The raw vulnerability in her eyes contrasted sharply with the sharp-edged woman who had slapped him moments before. He knew what that specialized serum meant. He knew the cost. “Marcello will have armed guards thick as smog,” he stated, his voice devoid of emotion, though his gaze lingered on Nico’s struggling form. “And the vault is sealed with a triple-layered arcane lock, keyed to his pulse and a vocal cipher. It cannot be breached.” “Then we’ll make it crawl,” Cosima retorted, already moving. “We can’t go in as ourselves. Not after what happened in the lieutenant’s suite. Not if we want to get close enough to the vault without triggering alarms the moment we step through the main gates.” She laid Nico gently back down, pulling a grimy blanket over him. His breathing was shallow, ragged. Every second counted. She snatched a length of tarnished copper pipe from a refuse pile, examining its weight and hollow interior. “The service tunnels below the Conservatory. They connect to the old laundry chutes. If we can get in there, we bypass the main security.” Her mind sorted through years of illicit routes and forgotten passages she’d memorized. “But we need a disguise. A Ferraro one.” Bastian’s brow furrowed. “I won’t wear their colours.” His tone was a flat refusal, laced with a pride that bordered on physical. The Salvati crest was practically tattooed onto his soul. “Oh, you will,” Cosima said, a wicked glint entering her eye. “Or Nico dies.” Her gaze swept over his imposing frame, the tailored vest, the immaculate trousers, the very air of command he exuded. A slow, predatory smile stretched her lips. “And I know just the uniform.” *** The servant’s livery was a garish ensemble of emerald green and gold, cheap, itchy wool that chafed Bastian’s skin. The collar was too tight, the sleeves too short for his muscular arms, exposing the dark, intricate tattoos that snaked up his forearms. A ridiculous cap, adorned with a limp, embroidered Ferraro spider, sat precariously on his head. Cosima had even insisted he smudge soot on his face and hands to complete the ‘lowly scullery boy’ effect. He looked absurd. And he hated it. Every fibre of his being screamed against the indignity. Cosima, by contrast, looked perfectly at home in her own stolen livery, a slightly less ridiculous dark grey uniform with a simple apron, her hair pulled back into a severe bun. She smirked at him as they crept through the shadowed sub-levels, the scent of stale cooking oil and cleaning chemicals thick in the air. “Don’t slouch, Salvati. Your posture screams ‘tycoon slumming it,’ not ‘starved errand boy.’ Try to look less… intimidating. More… servile.” Bastian shot her a venomous glare that would have curdled lesser men. “I will skin you alive for this, Vettori.” His voice was a low growl, barely contained. “Later, darling. After we save my brother and murder my boss, in that order.” She elbowed him sharply. “And stop glowering. You’ll scare the actual servants. Just think of it as… method acting. You’re playing the role of the humble nobody. You, Bastian Salvati, are beneath notice.” “Beneath notice,” he scoffed, adjusting the ill-fitting cap with a jerk. The indignity of the ruse chafed at him more than the coarse wool. “I will never be beneath notice.” “Oh, I know,” she murmured, her voice losing its teasing edge for a moment, a hint of something deeper in her eyes. “Believe me, I know.” They moved with practiced stealth, a strange, mismatched pair. Cosima knew the labyrinthine service passages of the Conservatory intimately, having used them for countless unsanctioned deliveries and hasty escapes. She pointed out narrow wall flues, loose floorboards, and the precise moment when the security patrol’s footsteps would fade. Bastian, despite his fury, followed her lead with chilling precision, his movements fluid and silent for a man of his size. The air between them, thick with bickering and shared peril, held a razor-edged tension born of their frantic alliance. They reached the vault antechamber, a small, heavily reinforced space hidden behind a false wall in the old kitchen pantries. The heavy steel door was etched with intricate arcane symbols, glowing faintly with trapped energy. Cosima pulled out a set of delicate lockpicks, her fingers moving with surprising speed and grace. “Marcello is a creature of habit. The outer locks are always standard, just heavily reinforced. It’s the inner wards that are the true nightmare.” With a series of soft clicks, the heavy bolts retracted. Cosima pulled the ornate brass handle. The door swung inward with a low, grating groan. A sickly sweet, metallic scent wafted out. Cosima’s eyes narrowed. “Damn it. A secondary ward. This isn’t standard.” As they stepped across the threshold, a faint, almost imperceptible shimmer pulsed through the air. A low hiss emanated from hidden vents in the ceiling, and a thin, opalescent mist began to swirl. Cosima immediately recognized the sharp tang and froze, her breath seizing in her throat. “Truth-gas,” she choked, pulling the collar of her tunic over her nose and mouth, though she knew it was futile. “A fast-acting alchemical variant. It compels honesty. Total, utter, stripping honesty.” Bastian coughed, his eyes watering. He tried to speak, to curse, but the words caught in his throat, then tumbled out, unfiltered and raw. “I hate this uniform! It makes my calves look stumpy, and I feel like a particularly ill-tempered, overgrown garden gnome!” Cosima stared, then barked a shocked laugh despite the growing panic. “Stumpy calves? That’s what you’re worried about right now?” The mist thickened. Bastian swayed slightly, his gaze locking onto Cosima with a focus that made her skin prickle. “And I… I’ve been tearing Canto apart for you, you infuriating, brilliant, deceitful viper! Every shadow, every hovel, every informant… and all the while, you were right there, playing me like a cheap fiddle, and I *admired* your ruthless intellect even as I wanted to wring your beautiful, lying neck! I… I think about you all the time! Your wicked smile! The way you argue! The scent of that cursed salve! It drives me mad! Mad!” His face flushed a deep crimson, a potent blend of fury and mortification. Cosima stared in mute astonishment. The gas was working on him with terrifying efficiency. She felt the urge to respond, to admit her own churning, complicated feelings about him, but she clamped her mouth shut, pressing her hands to her temples. “Gods, this is going to be painful.” “And your hip scar!” Bastian blurted out, a ragged, frantic note entering his voice. “The splintered star! It’s all I could see in the dark, and I knew… I knew I’d found you, but I wanted to rip you apart for the lies, and then kiss you senseless for being *you*!” Cosima could feel the truth bubbling up inside her, hot and corrosive. She had to focus. She couldn’t let the gas win. “The vault!” she gasped, pointing to a small, ornate chest tucked into a recess. “That’s where he keeps it! Quick, before we start confessing our childhood crushes!” Bastian, his features contorted in mortified sincerity, stumbled forward and fumbled with the chest. It was secured with a simple, keyed lock. Cosima, fighting the urge to tell him she’d thought about him too, about the unexpected warmth of his hand, the dangerous thrill of his presence, dug a smaller, specialized key from her pocket. She plunged it in, twisting. The lid sprang open. Inside, nestled on a bed of velvet, was a single, gleaming vial of the concentrated Vespian antitoxin, pulsating with a faint, cerulean light. Cosima snatched it, relief momentarily cutting through the agonizing pull of the vapor. “We have it! We have it!” Just as she turned, clutching the vial, a heavy *CRUMP* echoed through the antechamber. The vault door, solid brass and steel, slammed shut behind them with a resonant thud. The faint glow of the arcane symbols flared, then died, sealing them in absolute darkness. Then, a cold, familiar voice, amplified and distorted, resonated through unseen speakers. “Welcome home, Cosima,” Marcello Ferraro purred, his tone dripping with malice. “And you, Bastian. To your tomb.”
