Eivor is the central protagonist of Assassin's Creed Valhalla. Eivor is a Viking raider who leads a Norse clan from Norway to England during the ninth century.
The game allows the player to choose Eivor's presentation as male or female, while the character's name and core identity remain Eivor. The story follows the settlement of Ravensthorpe and the clan's alliances and conflicts across Anglo-Saxon England.
Eivor becomes connected to the Hidden Ones through Basim and Hytham. Their struggle against the Order of the Ancients forms the game's Assassin-related plot, while the wider story also explores Eivor's relationship with Sigurd and the Viking settlement.
Sigurd is Eivor's adoptive brother and an important story figure, but he is not the player character. Alfred the Great is a historical king who opposes the Vikings, and Basim is a Hidden One whose role becomes increasingly significant.
