The news of the "Sun-Stone" hit Alaric Vance like a physical blow. He sat in the quiet of the University library, the small, scorched note from Vane resting on the table. In the 21st century, the name for that stone was Uranium. It was the most dangerous material in the world, the key to the ultimate power, and the ultimate destruction.
"How, Elena?" Alaric asked, his voice a whisper. "How is he always one step ahead? I have the memories of a modern engineer. I know the blueprints. I know the history. But Vane... he's building things I haven't even thought of yet. How does a boy from the 11th century out-think a man from the future?"
Elena sat across from him, her face pale in the light of a single electric bulb. She didn't look at the note. She looked at Alaric.
"You have a weakness, Arthur," she said softly. "You have Ethics. You spend your nights worrying about the 'Dilemma.' You worry about the environment, the workers, and the future. You move slowly because you don't want to break the world."
She tapped the table. "Vane doesn't care about the world. He only cares about Winning. And he isn't working alone. He has something you don't, the Imperial Archive of the Forbidden Mountains."

How is Vane so smart? The answer wasn't magic. it was a dark, mechanical reality.
When Vane had been "recovered" by the Empire of Solis, they didn't just give him a lab. They gave him access to a hidden library found in a cave system deep in the Southern Marches, a place where another traveler had landed centuries before Alaric.
This traveler hadn't been an engineer. He had been a Military Scientist from a different timeline, one that had already perfected the art of the "Quick-Strike." He had left behind a "Manual of Ruin", a book of simplified, high-impact designs meant to conquer, not to build.
Vane wasn't inventing, he was Translating.
While Alaric was trying to build a stable civilization, Vane was simply following a "Cheat Sheet" for destruction. He didn't care if the steam engine blew up later, as long as it killed the enemy now. He was "ahead" because he took every shortcut Alaric refused to take.
---
"He's at the Great Dig," Alaric said, standing up. "If he gets enough of that Sun-Stone, he won't even need a rocket. He'll build a Dirty Bomb. He'll poison the entire valley of Oakhaven for a thousand years."
The Forbidden Mountains were a jagged wall of black rock three days to the south. The air there was said to be "Heavy," and the local tribes spoke of a "Sickness of the Bone" that hit anyone who stayed too long. In modern terms, the area was a natural uranium deposit, and it was leaking Radiation.
"We can't walk in there," Alaric told Kaelen and Harl. "The ground itself is poison. We need protection."
---
To fight Vane, Alaric had to invent the most advanced piece of safety equipment the Middle Ages had ever seen.
He used thin sheets of Lead, hammered until they were as flexible as leather. These were sewn into the lining of heavy canvas suits.
He created a Charcoal Filter Mask. It wouldn't stop the radiation itself, but it would stop the miners from breathing in the "Sun-Stone Dust," which was the most lethal part.
He built a primitive Geiger Counter. It was a glass tube filled with low-pressure neon gas and two wires. When a radioactive particle hit the gas, it would create a tiny "Spark" of electricity that would make a clicking sound through a speaker.
---
As Alaric's team reached the entrance to the Forbidden Mountains, the "Click-Click-Click" of the Geiger counter became a steady, terrifying roar.
The landscape was a nightmare. The trees were twisted and grey, and the water in the streams glowed with a faint, ghostly blue, a phenomenon called Cherenkov Radiation, though the locals called it "The Witch's Light."
"Look there," Kaelen pointed.
At the base of the tallest peak, a massive industrial operation was underway. Vane had used the Marquis's surviving labor force to dig a giant hole in the earth. Steam-powered cranes were pulling buckets of heavy, black ore from the depths.
The workers there weren't wearing lead suits. They were dying on their feet, their skin covered in sores, their hair falling out. Vane sat on a high platform, protected by a lead-glass shield, watching them like a cold god.
---
"He's not just mining it," Elena whispered, looking through the telescope. "He's Refining it. He's using a 'Centrifuge', a spinning machine, to separate the heavy parts of the stone."
Vane had built a row of giant, spinning drums powered by a massive steam engine. The noise was deafening. By spinning the crushed ore at incredible speeds, he was concentrating the uranium.
"We have to stop those drums," Alaric said. "If he finishes that batch, he'll have enough for a weapon."
Alaric didn't use his rockets this time. He used Chemistry.
He had brought several glass jars of Hydrofluoric Acid. In the 21st century, this was one of the most corrosive and dangerous liquids known to man. It could eat through glass, stone, and bone.
"We don't hit the men," Alaric commanded. "We hit the Bearings. If we melt the joints of those spinning drums, the whole system will tear itself apart."
---
Under the cover of a "Smoke Screen" (a mixture of zinc and sulfur), Alaric and Kaelen crept toward the refinery. The "Clicking" in their ears was so loud it felt like their brains were vibrating.
"Now!" Alaric yelled.
They threw the acid jars at the base of the massive steam-centrifuges. The acid hissed as it met the iron. It didn't just burn; it dissolved the lubricants and the metal axles in seconds.
The first drum, spinning at thousands of rotations per minute, suddenly lost its balance.
SCREE-BAM!
The iron drum tore itself off its mountings, flying through the air like a giant, jagged coin. It smashed into the next drum, and then the next. A "Chain Reaction" of mechanical failure ripped through Vane's refinery.
---
Through the clouds of steam and acid smoke, Alaric saw Vane. The Imperial scientist stood on his platform, his silver mask reflecting the chaos below.
"You're a fool, Arthur!" Vane screamed over the roar of the collapsing machinery. "You think you've saved them? You've just delayed the inevitable! I have the manual! I know what comes next! I have the Formula for the Star-Fire!"
"The manual won't save you from the Radiation, Vane!" Alaric shouted back, holding up his clicking Geiger counter. "Look at your hands! You're already dying, and you don't even know it!"
Vane looked down at his gloveless hands. They were trembling, and small, red spots were beginning to appear on his skin. For the first time, the "ahead" scientist looked afraid. He had the knowledge of how to build the bomb, but he hadn't read the chapter on Safety Protocol.
---
As the refinery burned, Alaric and his team pulled back. They couldn't stay any longer, even their lead suits were only a temporary shield.
"We stopped the mine," Kaelen said as they reached the fresh air of the northern pass. "But Vane... he got away, didn't he?"
"He did," Alaric said, his voice heavy with the "Dilemma." "And he took the manual with him. But he's sick, Kaelen. He's poisoned himself with his own ambition."
---
As they marched back to Oakhaven, Alaric realized the true reason Vane was always ahead. Vane didn't value Life. To Vane, people were just fuel for his machines. To Alaric, people were the reason for the machines.
"The race isn't over, Elena," Alaric said as the towers of Oakhaven appeared on the horizon. "He knows how to make the 'Star-Fire' now. He might be dying, but a dying man with the power of the sun is the most dangerous thing in history."
Alaric looked at the University. He knew what he had to do. He had to build the first Nuclear Bunker. He had to prepare Oakhaven for a world where the sky could turn to fire at any second.
The "Singularity" had reached its peak. The Middle Ages were no longer a time of knights and kings. They were the Atomic Middle Ages, and the clock was ticking toward zero.
