Idaho-11099 (d. 11099 AG),the consummate Atreidean supporter, rebelled against Leto's increasing authoritarianism and questioned his abuse of that same loyalty. He initiated the last, sad Sardaukar campaign, a move that resulted in Idaho's death, the final destruction of the Imperial Legions, and the founding of the Fish Speakers. The very notion of any Duncan Idaho leading the hated Sardaukar in an ill-fated yet grandiose, campaign battle against an Atreides is the stuff of which a latterday Harq al-Harba could have made great tragedy.
