The Obsidian Needle had become a monument of ice in the tundra, a jagged tomb for the Duke's ambitions. But for Leona, the victory was a heavy one. Her right arm, now a permanent fusion of flesh and frost-tempered mithril, hummed with a low, constant vibration that made her feel more like one of the Archive's ancient artifacts than a girl of fifteen.
Two months had passed since the battle in the wastes. Leona stood at the edge of a massive, rusted ventilation shaft on the outskirts of the capital city, Oakhaven. The air here was thick with the yellow haze of sulfur and the metallic tang of over-clocked mana-reactors.
"The capital hasn't changed," Kaelen whispered, adjusting the filters on his gas mask. He looked at Leona's mithril arm, which was partially hidden under a heavy, fur-lined cloak. "It just got louder."
"The King is nervous," Leona said, her voice sounding like ice cracking on a deep lake. "The images I broadcast from the Telegraph Company didn't just start a war in the South; they started a rot in the city. People are starting to ask why their 'modern' lives cost so much blood."
"And you think the answer is down there?" Kaelen gestured to the dark, steaming depths of the shaft.
"The 'Broken Gears' are the only ones who know the blueprints of the Palace's sub-levels," Leona replied. "If we're going to take the King's head, we can't go through the front gates. We go through the gut."
They descended.
The Clockwork Sewers were a marvel of discarded engineering. While the upper city thrived on clean, elegant mana, the sewers were a graveyard for the "failed" experiments of the Industrial Era. Massive, rusted cogs the size of houses turned sluggishly in pools of black oil. Steam-pipes hissed like dying dragons, and the walls were lined with the huddled forms of the 'Augmented'—men and women who had been partially replaced by machinery and then thrown away when a newer model was released.
Leona's Mithril Arm began to glow with a soft, pulsing violet light. It was sensing the sheer amount of 'leakage' mana in the air.
"Stay close," she warned Kaelen.
They hadn't walked a mile when the shadows began to detach themselves from the walls. These weren't the Alchemical Enforcers of the Duke; these were the Rust-Walkers. Their bodies were a horrific patchwork of brass, copper, and rotting leather. One had a steam-gauge for an eye; another had three mechanical arms ending in jagged shears.
"The Weaver has come to the pit," a voice rasped. It sounded like metal grinding on metal.
A figure stepped forward. He was almost entirely mechanical, his head a brass dome with a single, flickering blue lens. He wore a tattered Royal Engineer's coat, the gold braid tarnished to black.
"I am Unit 04, formerly High Engineer Marek," the machine said. "We saw your 'broadcast,' girl. We saw the names of the men who turned us into scrap. Why have you come to the grave?"
Leona stepped forward, letting her cloak fall open. The sight of her mithril arm caused a collective hiss of steam from the Rust-Walkers. In the hierarchy of this world, mithril was the ultimate status symbol—the 'Modern' gold. To see it on a girl in the sewers was an affront.
"I didn't come to the grave to mourn," Leona said, her eyes turning that terrifying, opaque white. "I came to wake the dead."
"We are not dead," Marek spat, a puff of black smoke erupting from his neck-vents. "We are merely... inefficient. The King's Technomancers decided that human souls were too 'volatile' for the new engines. They stripped our hearts and replaced them with clockwork. We can't even feel the cold anymore."
"Then feel this," Leona said.
She slammed her mithril hand onto a nearby steam-pipe. She didn't freeze it. Instead, she used the Mithril Weave to conduct the heat away from the pipe and into her own core, then redirected it.
She turned the chaotic, waste-heat of the sewers into a perfectly synchronized pulse of energy. The rusted cogs in the room suddenly began to spin with a smooth, silent precision they hadn't possessed in decades. The flickering blue lenses of the Rust-Walkers stabilized, turning a deep, calm sapphire.
For the first time in years, the "noise" in their heads—the grinding of faulty gears—stopped.
"A Harmonic Sync," Marek whispered, his brass dome tilting in shock. "You didn't just fix the machinery. You... you tuned it."
"I am a librarian," Leona said, retracting the silver threads back into her skin. "I know how to organize chaos. The King thinks you're scrap because you don't fit his 'New Order.' But I see an army that knows every secret passage, every structural flaw, and every pressure-point of this city."
She looked Marek directly in his blue lens. "Help me open the Palace, and I will give you the one thing the King took from you: a purpose that isn't measured in output."
Marek stood silent for a long moment, the only sound the rhythmic ticking of his internal clock. Then, he knelt—a jarring, mechanical movement that echoed through the tunnel. One by one, the other Rust-Walkers followed suit, their jagged shears and brass limbs clattering against the stone.
"The Sewers are yours, Weaver," Marek rasped. "Where do we strike first?"
Leona pulled out the Gray Book. She flipped to a page she had never shown Bram or her mother. It was a map of the Palace's 'Great Mana-Reservoir'—the source of all power for the King's automated defenses.
"We don't strike the King," Leona said. "We strike the light. We're going to turn Oakhaven back into a medieval kingdom for one night. And in the dark, the shadows are the only ones who can see."
As they began to plan the infiltration, Leona sat in a corner of the rusted chamber, her mithril arm feeling heavier than usual. She looked at her reflection in a pool of oil.
She realized that by leading this army of monsters, she was finally finishing the story her father had started. Silas Argen had been the 'King of Assassins' in a world of blades. She was becoming the 'Queen of the Cold' in a world of machines.
But as she touched the cold metal of her arm, she wondered: When the King is gone and the fires are out, what will be left of the girl who just wanted to read books?
She pushed the thought aside. In the modern world, there was no room for "What if." There was only the next page.
