Einar (pronounced EYE-nar), often known as Einar the Venomous, was a jarl of Rothurland. Known for his trickery and duplicity, Einar controlled the northern fjords around Veden and Norheim for many years until killing Ragnarr the Mad Boar in Y9960*, taking the defeated jarl's lands, and soon after meeting his defeat at the hands of Ragnarr's children in Y9964*.
In Y9960*, Einar launched an attack on Shivering Fjord when Ragnarr was visiting. After killing most of Ragnarr's accompanying retinue, Einar took Ragnarr with him back to Veden where he was executed by being thrown into a pit of venomous snakes. Having defeated the rival jarl through underhanded means, Einar then claimed the entirety of Ragnarr's jarldom as his own.
When news of Ragnarr's death reached his family in Svarheim, his children were enraged and immediately set about getting revenge against the killer of their father. After fighting through Einar's soldiers, Ladgerda the Swan finally slew the jarl at a battlefield near Norheim. Today Einar's former holdings in the fjords are controlled by Ladberda.
