Sigsland

Region in the northeast of The Empire, home to the Sigsmen. Prior to its conquest by The Empire in 371, Sigsland was the Kingdom of Sigsland. Modern Sigsland is divided into many smaller states, the largest of which are the Margraviate of Brandbrug and the Duchy of Dundgren.
Triarchism is particularly common in Sigsland, and the region saw much of the fighting in the Triarchist Crusade.
