Eivor is the Assassin's Creed protagonist who belongs to the Viking Raven Clan.
Assassin's Creed Valhalla follows Eivor Varinsdottir, who leads the Raven Clan from Norway to England during the Viking expansion of the ninth century. Players can choose a masculine or feminine presentation for Eivor, but the character's name and clan affiliation remain central to the story.
Eivor establishes a settlement in England and becomes involved with the Hidden Ones, the precursor organization to the later Assassin Brotherhood. The game combines Viking political alliances, raids, exploration, and the series' continuing conflict with the Order of the Ancients.
Basim is a Hidden One who becomes a major character, Sigurd is Eivor's adoptive brother, and Hytham is another Hidden One. They are all important to Valhalla, which is why they can seem like possible answers, but Eivor is the Raven Clan protagonist.
