Ivar (pronounced EYE-var), often known as Ivar the Glass-Armed, is a jarl of Rothurland. Along with his half-sisters Aslaug the Star-Eyed and Ladgerda the Swan, Ivar is one of three current jarls who are children of Ragnarr the Mad Boar. After his father was killed by Jarl Einar the Venomous, Ivar took control of the island city of Orsa, claiming it as a jarldom for himself.
Born with a condition that causes his bones to fracture incredibly easily, Ivar was unable to become a warrior like some of his siblings. Instead, he has cemented his rule through his skills as a military strategist. Though Ladgerda may regard him as weak, and Aslaug may consider him lacking in ambition, Ivar's talents were instrumental in enacting the siblings' shared revenge against Einar.
As jarl, Ivar controls only the island on which Ormsa is located. He prefers not to involve himself in the affairs of his siblings, or any other jarls, and leaves his realm only on rare occasions.
