Zenus

Zenus the Architect, also known as The Almighty is an important figure in Dragon Quest IX. He's revered in churches around the world as the creator of the mortal world and even Celestrians look up to him, hoping one day to acend to his realm.

Backstory
Although he's not one of the main villains, there are some occasions in which its decisions are frowned upon; he was about to erradicate the mortal world because he had lost faith in the people because they had lost faith in him, this would have happened had it not been for his daughter, Celestria, who turned into the tree of Yggdrasil and decided to remain like that until Celestrians could ascend to his realm, that is, until they had gathered enough benevolessence through faith from mortals. After Corvus' lightning struck his realm, his whereabouts become unkown, but apparently he becomes fractured into several monsters that inhabit the various grottoes.
