Leif was a Viking warrior who joined Ragnar Lothbrok's war band in the exploration westward. Like his father, Erik, Leif was a veritable giant of a man, among the tallest and largest of his Viking comrades.
As a brave warrior and loyal friend of Ragnar Lothbrok, he went on both expeditions to Northumbria. In Uppsala he chose himself to be sacrificed in place of Athelstan because he wanted the best for his people and their new leader, Earl Ragnar Lothbrok.
- As a trusted companion of Ragnar Lothbrok, Leif held the status of a Skutilsvein (table-man), an officer with an Earl's Hird (warband and household guard).
- Leif's tattoo depicts Jörmungandr, in a shape similar to the triple moon symbol.
