The war between Oakhaven and the Empire of Solis was no longer about knights on horses or even iron tanks on the ground. It had moved into the empty spaces of the sky. Alaric Vance had invented the "Shadow-Wing" to stay quiet, but Vane, his former student turned Imperial scientist, had decided that if he couldn't hear the Architect, he would simply look down on him from a place Alaric couldn't reach.
---
It started on a Tuesday morning. The farmers in the northern valleys of Oakhaven looked up and saw a silver speck in the blue. It didn't move like a bird. It didn't glide like Alaric's gliders. It sat perfectly still, high above the clouds, glinting like a misplaced star.
"It's a 'High-Altitude' balloon, Arthur," Elena said, her voice trembling as she adjusted the University's giant telescope. "Vane has moved past hot air. He's using Hydrogen."
Alaric looked through the lens. The balloon was massive, a sphere of gold-beaten silk. Below it hung a stabilized wooden platform. Even from miles away, Alaric could see the glint of huge glass lenses. Vane wasn't just watching the borders, he was mapping every street, every factory, and every hidden telegraph line in Oakhaven.
"He's turned the sky into a Mirror," Alaric whispered. "From that height, he can see the heat from our furnaces. He can see the wake of our submarine. We have no more secrets."
---
In the 21st century, you would just use a missile. But in 1042, the "High Ground" was a literal wall. The balloon was sitting at 30,000 feet. The air up there was thin and freezing. Alaric's cannons couldn't aim that high, the gravity of the earth would pull the heavy iron balls back down long before they reached the silk.
"We can't fly to it," Kaelen said, looking at the Shadow-Wing. "The air is too thin for the wings to grip. And we can't shoot it. So what do we do? Just let him watch us eat our breakfast?"
Alaric sat at his wooden desk, his mind racing through the laws of Physics and Chemistry. He needed a way to send a message to the edge of space. He needed something that didn't rely on the "grip" of the air. He needed a Rocket.
---
Rockets weren't new. The ancient world had used "fire-arrows" filled with black powder for centuries. But those were wild, tumbling things. They flew for a few hundred yards and then exploded. To hit a target six miles up, Alaric needed Stability and Multi-Stage Power.
"We're going to build a 'Sky-Piercer'," Alaric told the Engineering Union. "It's not a cannonball. It's a self-moving engine."
The workers, led by Harl, began to assemble the pieces. This was the most dangerous thing they had ever built.
Alaric didn't use simple gunpowder. He created a Solid-State Propellant, a mixture of sugar (sucrose) and potassium nitrate. It burned slower but with much more "Thrust."
Instead of heavy iron, which would be too heavy to lift, they used Layered Paper and Resin. It was light, strong, and wouldn't turn into deadly shrapnel if it failed on the launchpad.
To keep it straight, Alaric added angled fins at the bottom. These would make the rocket spin like a bullet, using Centripetal Force to keep it on target.
---
The "Sky-Piercer" sat on a wooden rail in the center of Oakhaven. It looked like a giant, pointed pencil made of dark wood and copper. At the very tip was a small glass jar filled with "Devil's Dust" and a primitive Impact Trigger.
"If this works, Arthur," Elena said, standing far back behind a stone wall, "you've just invented the first tool of 'Global Reach.' You've made it so no place on Earth is too far away to hit."
"I know," Alaric said, his hand over the electrical ignition switch. "But Vane started this. He took the 'Eye.' Now I have to take the 'Hand'."
He flipped the switch.
WHOOSH.
A pillar of white smoke erupted from the base of the rocket. It didn't "bang" like a cannon; it roared. The Sky-Piercer accelerated, trailing a long ribbon of fire as it vanished into the blue.
---
High above, on the Imperial platform, the observers saw the smoke trail. They tried to cut the tether and drift away, but the rocket was too fast.
From the ground, Alaric watched through the telescope. The rocket looked like a tiny needle chasing a giant bubble. For a moment, it seemed to miss. The thin air at that height made the fins wobble.
But Alaric had added a Secondary Stage. A smaller rocket inside the big one ignited, giving it one last burst of speed.
POP.
A tiny orange spark appeared against the gold silk of the balloon. It wasn't a big explosion, at that height, there wasn't enough oxygen for a giant fireball. But Alaric didn't need a fireball. He just needed a Tear.
The hydrogen inside the balloon met the spark. The "Eye in the Sky" turned into a falling sun. The silk shriveled, and the wooden platform began its long, tumbling descent back to the Imperial border.
---
Oakhaven cheered. The "Star" was gone. The sky was empty again. But Alaric Vance didn't join the party. He walked back into the University, his boots heavy on the stone floor.
"We won, Arthur!" Kaelen shouted, clapping him on the back. "The Marquis's spies have nothing to look at now!"
"No, Kaelen," Alaric said, sitting down in the dark. "We didn't just win a battle. We just proved that the sky is a Battlefield. Do you know what Vane is doing right now?"
"Crying?" Kaelen guessed.
"No," Alaric said. "He's looking at the wreckage of our rocket. He's looking at the sugar-fuel. He's looking at the fins. And he's realizing that if he can put a camera on a rocket, he can put a Bomb on one."
---
That night, Alaric looked up at the stars. For the first time, they didn't look like distant lights of hope. They looked like targets.
He realized that by solving the "Dilemma" of the balloon, he had created the "Dilemma" of the Intercontinental Strike. He had given the 11th century the power to kill from across the world without ever seeing the enemy's face.
"We need to build a 'Shield', Elena," Alaric whispered as she entered the room.
"A shield for the whole kingdom?" she asked.
"A shield for the Mind," Alaric said. "We have to stop thinking like builders and start thinking like Survivors. Vane is going to build a bigger rocket. One that doesn't just go up, but goes over."
---
Before the sun rose, a messenger arrived at the University gates. He didn't wear the Imperial Sun. He wore a simple grey cloak. He handed Alaric a small, scorched piece of paper recovered from the fallen balloon.
It was a note from Vane.
"You hit the Eye, Arthur. But you forgot that the Eye has a Brother. Look to the South. The 'Black Tide' was just the beginning. We've found the 'Sun-Stone'."
Alaric's heart stopped. "Sun-Stone." In the 21st century, that was a nickname for Uranium.
"Elena," Alaric called out, his voice cracking. "Forget the rockets. We need to talk about Geiger Counters."
The "Singularity" had reached its most terrifying point. The Middle Ages were about to enter the Atomic Age, and Alaric Vance was the only man who knew how to stop the world from turning into glass.
