Assassin's Creed Valhalla is primarily set in 873.
The game follows the Viking raider Eivor during the late ninth century. Eivor leads a Norse clan from Norway to England, where the group establishes a settlement and becomes involved in conflicts among Anglo-Saxon kingdoms, Viking forces, and the Hidden Ones. The campaign's central events begin in 873, although the narrative includes memories, visions, and sequences that extend beyond its main period.
Valhalla's English setting reflects the fragmented political landscape of the time. Kingdoms and rulers associated with Wessex, Mercia, Northumbria, and East Anglia appear in the story. The game also includes Norway and later areas connected to the wider narrative.
The date is sometimes confused with the Viking raid on Lindisfarne, which occurred in 793. That event is historically important but predates Valhalla's principal storyline by roughly eighty years. Valhalla was released in 2020.
