Odin is the Norse god-inspired identity connected to the protagonist in Assassin's Creed Valhalla.
Valhalla's protagonist is Eivor, a Viking who leads a clan from Norway to England during the ninth century. The game's mythology storyline reveals that Eivor is the reincarnation of Odin, also called Havi in the mythological sequences.
This reveal is tied to the Isu, the advanced civilization that appears throughout Assassin's Creed lore. The Norse gods shown in visions and mythological quests are presented through an Isu-related interpretation rather than as ordinary historical events.
Eivor and Odin are not simply two interchangeable playable characters. Eivor remains the protagonist of the historical storyline, while Odin's identity explains recurring visions, memories, and themes involving fate, sacrifice, and survival.
