Assassin's Creed Valhalla primarily begins its story in 873.
The game follows Eivor, a Viking raider who leaves Norway with the Raven Clan and settles in England. Its main historical setting is the Viking expansion into England during the late ninth century, with the settlement at Ravensthorpe becoming a central base.
Valhalla's opening events occur in Norway before the story moves to England. The game then spans several years and incorporates historical kingdoms, political alliances, and conflicts involving figures such as Alfred the Great.
The date is sometimes confused with the Viking raid on Lindisfarne in 793, a famous event that predates the game's opening by eighty years. The game was released in 2020, but its story's historical beginning is 873.
