Dormammu is a powerful extradimensional being older than time itself. He is the malevolent ruler of the Dark Dimension. Dormammu wishes to use his power to conquer every dimension of the multiverse, but his efforts to destroy the Earth were stopped by the Masters of the Mystic Arts, who took measures to prevent him from entering our dimension by constructing the Sanctum Sanctorums. Dormammu would ultimately strike a deal with Kaecilius, who lead a separatist faction of the Masters of the Mystic Arts known as the Zealots. Kaecilius would eventually destroy two Sanctum Sanctorums, allowing Dormammu to begin fusing the Earth into the Dark Dimension. However, Dormammu was confronted by Doctor Strange, who used the Eye of Agamotto to keep Dormammu trapped in an endless time loop, unless Dormammu and the Zealots left the Earth and never return. Dormammu was unable to defend himself against time, a concept that was foreign to him, forcing him to agree to Strange's terms. Dormammu than banished himself and Kaecilius's forces from the Earth, sealing the interdimensional portal between Earth and the Dark Dimension.
