The Eve of the Storm

The gateway city of Graufeld, guarded by the 15th and 16th Corps of Army Group B, was geographically vulnerable to attack.

Unlike those in other regions, the walls of Graufeld were relatively low.

This was less the fault of those who built the defensive line than a consequence of the North's terrain.

The area around Graufeld stood at a considerably higher elevation than other regions. Its average elevation ranged around 2,000 meters above sea level.

An elevation of 2,000 meters might be hard to picture, but South Korea—the part of Korea we can see for ourselves—has no mountains higher than 2,000 meters.

Even on terrain this steep, they couldn't build fortifications dozens of meters high. No matter how many superhuman beings existed in this world, transporting massive construction materials to such heights was no easy task.

As a result, the walls in the Graufeld region were not much different from ordinary city walls. In places where the terrain made building walls difficult, they might even have to fight hand to hand.

Even so, they couldn't abandon this high-altitude region because of the length of the mountain range.

The Graufeld mountain range stretched all the way to the heart of the North. If they abandoned it, part of the defensive line would have to fall back as far as the North's interior.

That would make the defensive line far too long, since they would have to build a massive wall along a mountain range dozens of kilometers long...
