The Border between Xadia and the Human Kingdoms is a churning river of molten lava, created by powerful Dragons when humans were driven to the west for practicing Dark Magic. It is a horrific scar in the land and extremely dangerous for even the most seasoned explorers and soldiers. Katolis keeps The Standing Battalion, one of its most powerful armies, on constant guard at a fortress located there. Its troops are led by General Amaya, an iron-fisted commander with a deep hatred for Xadia.

The Border is protected by Thunder, The Dragon King.
