Bjorn Ironside (pronounced be-YORN) is a werebear and jarl of Rothurland. He is known for being highly protective of the people living within his realm, to a greater degree than is considered typical for jarls. His realm is also one of the few in Rothurland that has a history of hereditary inheritance - before Bjorn, the territory was controlled by his father and grandfather.
Bjorn has a number of trained cave bears that serve as companions and as guards to his longhouse.
As jarl, Bjorn controls the area between the Hvitna and Vara rivers, including the settlements of Hreinholt, Dyrfang, Fornheim, and Grimfell. The expansionist frost giant Jarl Hrimnir has begun pushing into Bjorn's northern and eastern territories, something that has enraged the werebear.
