The Borderlands is a demilitarized region that separates the two great kingdoms, the Empire and the Kingdom of Aramon. It is ruled by the Trade Lords, powerful and wealthy nobles that own specific parts of the Borderlands.
The Borderlands are rich in resources. The soil is fertile and produces bountiful harvests and the hills are rich in mineral resources. Both the Empire and Aramon want access to these resources, but due to the ancient treaty that formed the Borderlands region in the aftermath of the civil war, both sides had to pay vast sums of money to the Trade Lords, making the noble families the richest in the entire continent.
The Trade Lords convene for council in the city of Cathalon. While not an actual country per se, the Trade Lords each have their own disputes and convene to hopefully deal with their issues peacefully. Civil wars between Trade Lords have happened before in the past. Mercenaries are eager for these conflicts to happen, as they are well compensated for their efforts.
