Gallus is the political seat of the Gallandrie, a kingdom of men in the Gallandrie Badlands.
According to its own myths, it was founded by Gallus, who was exiled from the settlement of Riverside. Gallus traveled over the Gallandrie mountains without any supplies or companions in the middle of winter. When he arrived in the badlands, he united the tribes of the Frid people, driving out the monsters and savage humanoids to civilize the badlands.
Gallus has historically always been at odds with Minos, but the mountains interposed have both prevented outright war and allowed the two rival nations to continue to foster unresolved cultural animosities. The presence of the giants in the mountains acts as a buffer as well against any territorial disputes, and largely prevents the people of either kingdom from mining the resources of the mountains.
