Eivor is the first name of the Viking protagonist who leads the Raven Clan in Assassin's Creed Valhalla.
Eivor is a Viking from Norway who travels to England with the Raven Clan during the ninth century. The character can be presented as male or female, but both versions use the name Eivor. The story follows the settlement of Ravensthorpe and the alliances Eivor builds among competing English kingdoms and communities.
Valhalla incorporates historical figures and events from the Viking expansion into Anglo-Saxon England, while also continuing the series' conflict between Assassins and Templars. Eivor encounters members of the Hidden Ones, the organization descended from the protagonists of Origins, and opposes the Order of the Ancients.
Sigurd is Eivor's adoptive brother and an important story character, not the playable protagonist. Ivarr and Ragnar are historical or story figures associated with the period, but neither leads the Raven Clan in the game. This distinction matters because the campaign contains many prominent Viking names.
