Upon learning of the recordings of Andraste that was scriptured by her before her death they learned of the Dormant Golden Dragons of the Maker led by the Golden Dragon Bahamut, it is also revealed that Dumat is short for Tiamat, the elder brother of Bahamut who was cast out of the Maker's favour after the First Sin.
Rise of the Dark GodsEdit
Awakening of BahamutEdit
Bahamut began his awakening with the unnatural return of Dumat, the Dragon of Silence or Tiamat, King of Black Dragons. Dumat's personality was destroyed as his body was crafted into a dark verison of the Blood Dragon Armor Set, his power and knowledge was turned into an orb of energy which could be absorbed by a Darksider however to awaken Dumat's control of the Taint they required a powerful opposing force, to do this they needed Dumat's Brother: Bahamut, to manifest from the Fade as ruler of the Golden Dragons which both Dumat and Bahamut found themselves the guests of twins.
