Moneo Atreides

Moneo Atreides is a fictional character in the Dune universe created by Frank Herbert. He is featured in the 1981 novel God Emperor of Dune.

Majordomo Moneo Atreides (13,610-13,728) is one of the finest and underused examples of Atreides breeding plan. He is a blur of grace and power in both physical and mental ability, and among his ancestors is not only Ghanima Atreides and Farad'n Corrino/Harq al-Ada, but also Duncan Idaho. Moneo refused to use the spice melange in order to make his life any longer.

Moneo has the misfortune of being born at a time when being a superhuman Atreides is not quite enough. He becomes the closest and most trusted servant/caretaker of Leto Atreides II.

Moneo's daughter, Siona is a rebel and an upstart but it is revealed that Moneo too was a rebel at one point and Leto II considers it a mark of great intelligence and honor for a future trustee of the Golden Path to question his rule.

Moneo never flaunts his power, the closest he ever comes to this is a moment where he warns Duncan Idaho that even with Idaho's Ginaz Swordmaster training, the evolved Atreides could kill him in seconds.

Moneo carries himself with a quiet dignity and poise, serving without personal ambition. He acts as a first line perhaps as a way of saying, "If you can not best the pinnacle of human Atreides evolution, what hope do you have against Leto II?"
