The Bizogot was a common ethnicity of the different barbarian tribes and of the Raumsdalian Empire. They were mammoth-herding nomads who lived close to The Glacier. They scorned the Raumsdalians for being too soft.
During the reign of the Raumsdalian Emperor Sighvat II, the Bizogot clan the Three Tusk discovered Gap in the Glacier. Their jarl, Trasamund, was par of the expedition to discover the lands north of the Glacier.
There they discovered a race of warriors known as the Rulers who planned to invade to everything south of the Glacier. Due to the proximity to the Gap, they bore the brunt of the attack.
