Thor returns from a period of self-induced hibernation in a third self-titled volume, and enters the Odinsleep to find Odin in a limbo dimension between life and death, where Surtur stored a portion of his essence to prevent himself from being killed forever. Here Odin and the demon battle to the death, being reborn each day to repeat the cycle, preventing either from being reborn. Thor helps Odin beat Surtur twice, even though he will be reborn, before returning to his body. Thor offers to help Odin escape from this realm and the constant battle with Surtur. Odin chooses to remain in order to protect his people from the demon.
