Which Assassin's Creed game introduced the playable Viking protagonist Eivor Varinsdottir?

Assassin's Creed Valhalla introduced the playable Viking protagonist Eivor Varinsdottir.

The game follows Eivor from a Norwegian settlement to ninth-century England, where Eivor helps establish a new home for the Raven Clan. Players can choose a male or female presentation for Eivor, but the character's canonical name is Eivor Varinsdottir, with “Varinsdottir” meaning daughter of Varin in the game's naming convention.

Eivor becomes connected to the Hidden Ones and opposes the Order of the Ancients, the organization that precedes the later Templar Order. The story includes settlement building, raids, alliances with English kingdoms, and a substantial modern-day thread involving Layla Hassan.

Valhalla is often confused with Odyssey because both are large role-playing games with selectable protagonist presentation and ancient-world settings. Odyssey stars Kassandra or Alexios in fifth-century BCE Greece, whereas Valhalla centers on Eivor during the Viking expansion into England. The two games therefore differ in protagonist, era, and region.
