The humid, sulfurous air of the catacombs had begun to change. No longer did it smell only of ancient dust and stagnant water; now, it carried the sharp, ozone tang of Priscilla's "miracle." Deep within the sub-basement of the Holy See, the silence was shattered by the rhythmic, mechanical heartbeat of a clandestine world.
Priscilla stood at the center of the vault, her duster discarded. She wore a work-tunic with the sleeves rolled up, her forearms smudged with grease and cooling-oil. Before her sat the "Heart"—a massive, vertical steam-turbine she had designed to tap directly into the thermal geysers of Veridia. It was a beast of brass and reinforced iron, its governor spinning with a dizzying, hypnotic blur.
"Pressure is holding at ninety pounds per square inch," Jax reported, wiping soot from his brow. The boy had adapted with terrifying speed. He didn't just follow orders; he anticipated the needs of the machinery. "The copper coils are humming, My Lady. The light-lines in the upper tunnels are active."
"Keep the baffles closed," Priscilla commanded, her eyes fixed on a pressure gauge. "The moment the steam vents too loud, the priests will think the Earth is screaming. We cannot afford a 'divine omen' tonight."
But the interference didn't come from the priests.
High above, in the moonlit spires of the Eastern Delegation, Lyra Zephyros sat in a circle of white salt. Her silver hair defied gravity, floating as if underwater. She held a crystal prism to her eye, peering not at the physical world, but at the flow of mana.
"There is a parasite," Lyra whispered, her voice distorted by the trance. "A cold, iron mouth is sucking the warmth from the holy springs. It tastes like... lightning and dead metal."
She bit her thumb, drawing a single drop of blood onto a silver bell. "Go," she commanded. "Find the void. Silence the heartbeat."
Back in the catacombs, the temperature suddenly plummeted. The glowing electric bulbs Priscilla had strung along the damp arches flickered and dimmed, their filaments whining.
"My Lady?" Jax reached for a wrench, his eyes darting toward the darkness of the lower tunnels. "The Heart... it's slowing. But the pressure is the same."
Priscilla didn't look at the machine. She reached for her thigh, her fingers closing around the cold, textured grip of her hand-cannon. She felt a ripple in the air, a pressure differential that had nothing to do with steam.
"Jax, Hagar, get behind the lead shielding. Now!"
From the shadows emerged a 'Spirit-Assassin'—a construct of pure, solidified wind and condensed mana. It had no face, only a swirling vortex of silver mist and two blades of jagged ice where hands should be. It moved without sound, a silent blur of lethal intent sent by the East to prune the 'technological rot' from the world.
The creature lunged. It didn't strike like a human; it moved like a gust of wind, appearing instantly in Priscilla's personal space. The ice-blade whistled toward her neck.
Priscilla dived, rolling across the stone floor with the grace of a panther. She didn't panic. Her mind was already calculating the assassin's density. It's not solid. It's a localized weather system. Kinetic force won't stop it... but heat will.
"Jax! Open the main bypass valve! Vent the thermal steam into the chamber!"
"But My Lady, you'll be scalded!"
"DO IT!"
Jax slammed the lever. A deafening roar erupted as a gout of super-heated, high-pressure steam flooded the vault. The room became a white-out of blistering vapor.
The Spirit-Assassin shrieked—a sound like glass breaking. The sudden injection of thermal energy disrupted the delicate magical balance of its wind-form. It began to dissipate, its silver mist thinning as the steam tore its structure apart.
Priscilla didn't wait. She tracked the glowing core of the creature—a small, pulsating blue crystal at its center. She leveled her hand-cannon, her eyes narrowing through the steam.
BANG.
The lead ball, coated in a magnesium-salts mixture she had prepared for just such an 'unnatural' occasion, tore through the vapor. It struck the crystal core with the force of a falling star.
The explosion was blinding. The blue crystal shattered, releasing a shockwave of cold mana that condensed the steam into a sudden, freezing rain.
Priscilla stood in the downpour, her chest heaving, her weapon still smoking. The Spirit-Assassin was gone, reduced to a pile of melting slush on the catacomb floor.
She walked over to the shattered remains of the blue crystal. She picked up a fragment, feeling the residual hum of Lyra Zephyros's magic.
"So, the East wants to play," Priscilla whispered, her voice a low, terrifying promise. She looked up at the ceiling, as if she could see through the miles of stone to the silver-haired mage above. "You sent a ghost to kill a machine, Lyra. Next time, send something with a heart. It'll be easier for me to stop."
She turned back to her crew, who were emerging from the shadows in awe. "Fix the valves. Reset the turbine. We have three more light-lines to lay before dawn. If the East thinks they can snuff out my light, they're going to find out just how bright I can burn."
