Verified Timeline
Lore & Background
In Valhalla, the narrative depicts tensions between descendants of Vikings (Norse or Danes) and native English reaching a breaking point. Olaf Haraldsson is cast as a fictionalized composite character, appearing in seasons one and two alongside main characters like Leif Erikson and King Canute the Great. The story covers the clash of conflicting Christian and pagan beliefs among the Norse themselves. While historical records mention Swein Forkbeard uniting Vikings to raid England for over a decade before taking the throne, the series depicts Swein as a king who dies in Season 1, Episode 8. Olaf exists within this fictionalized timeline where Cnut becomes joint ruler of England alongside Edmund II, contrasting with known history where Aethelred was forced into exile first.
