Emperor Mikael II Atreides (d. 4915 AG) called "The Depraved" was the son of Atreus Atreides Atreides. He succeeded his father and seemed to follow his reforms during the first years. After almost dying from chaumurky, he harassed the Landsraad, accumulated personal rule and started an unparalleled reign of terror which resulted in a massive popular revolt. He left the throne and retired in cryogenic suspension along his son in 4670 AG, with a pretext (released after his disappearance) that he retired to a monastery. His absence was followed by the Second Republic.
