Assassin's Creed Valhalla: Dawn of Ragnarök is a story expansion for Assassin's Creed Valhalla that focuses on Eivor's visions of Odin. Set in the dwarven realm of Svartalfheim, it follows Odin as they attempt to rescue their son Baldr from the fire giant Surtr while the realm is occupied by forces from Muspelheim and Jotunheim. The expansion adds a new open-world region and the Hugr-Rip, an artifact that lets Odin absorb and use powers from defeated enemies. Players use these abilities in combat, traversal, and exploration as they progress through a storyline tied to the events leading up to Ragnarök.
