What is the name of the male protagonist option in Assassin's Creed Valhalla?

The male protagonist option in Assassin's Creed Valhalla is Eivor Varinsdottir.

Eivor is a Viking raider from Norway who leads a clan to England during the ninth century. Valhalla lets players choose a male or female presentation for Eivor, but both versions use the same character identity and surname. The game also includes an option to let the Animus switch between the two presentations in particular contexts.

Eivor becomes involved with the Hidden Ones, including Basim and Hytham, while building an English settlement and forming alliances with regional rulers. The story combines Viking expansion with the continuing conflict between the Hidden Ones and the Order of the Ancients.

Sigurd is Eivor's adoptive brother, not the protagonist. Basim is another major character, but he is also not the player character.
