Eivor Varinsdottir is the Assassin's Creed Valhalla protagonist who begins as a Viking raider.
Valhalla opens in ninth-century Norway before Eivor leads a clan to England. The player can choose Eivor's presentation as male or female, but the character's canonical name is Eivor Varinsdottir. The surname uses the Norse naming convention meaning “daughter of Varin,” even when the male presentation is selected.
Eivor establishes a settlement in England and becomes entangled with the Hidden Ones and the Order of the Ancients. The game combines Viking-era politics, raids, alliance-building, and exploration with the series' continuing science-fiction framework.
Kassandra belongs to Assassin's Creed Odyssey, while Basim is a major character in Valhalla and the protagonist of Assassin's Creed Mirage. Sigurd is Eivor's adoptive brother and a major story figure, not the playable protagonist.
