Great Eastern War

Queen Tashanna of Irrisen invaded the western region of the Realm of the Mammoth Lords in what became known as the Great Eastern War in 4155 AR. Within a year she conquered all the lands between the Frozen Road River and the Gullik River to the base of the Tusk Mountains and established a new Irriseni province named Rimetusk. She also laid the foundation of the city of Tashagrot to serve as Rimetusk's provincial capital.
