Odin is the Norse god associated with Eivor's recurring visions in Assassin's Creed Valhalla.
Eivor experiences visions and dreamlike sequences that connect the Viking protagonist to the mythology of Odin, also known as Havi in the game's Isu-related interpretation. These sequences are woven into the wider story rather than being simple retellings of traditional Norse myths.
Valhalla deliberately links Norse mythology with the series' science-fiction concept of the Isu, an advanced civilization that existed before recorded human history. The connection creates a second layer of meaning: legendary gods are also connected to characters and events in the franchise's earlier-world history.
Thor, Loki, and Tyr are also important Norse figures and appear in the game's mythological material, so they are plausible alternatives. However, Odin is the specific figure linked to Eivor's recurring visions. Valhalla was released in 2020.
