Eivor is the Animus subject controlled by players in Assassin's Creed Valhalla.
Eivor Varinsdottir is a Viking raider who leaves Norway and helps establish a settlement in England during the ninth century. The character can be presented as male or female, but the name Eivor identifies the central historical character and the player's main avatar in the Viking-era storyline.
The modern-day framing plot is led by Layla Hassan, who uses the Animus to investigate the memories connected to Eivor. Basim Ibn Ishaq is another important character, but he is not the protagonist controlled throughout the main historical campaign. Kassandra belongs to Assassin's Creed Odyssey.
Ubisoft released Valhalla in 2020. Its historical setting includes Anglo-Saxon kingdoms, Viking expansion, and the conflict involving the Hidden Ones and the Order of the Ancients. Although marketed around Vikings, the game remains part of the broader Assassin's Creed mythology and its memory-based Animus structure.
