After the bonding of Siona and a ghola of Duncan Idaho, the Atriedes families continued onward. One such group of descendants of Ghanima were Leto II's, majordomo, Moneo Atreides, and his daughter Siona Atreides. However, the Atreides bloodline continued through Leto II's twin sister (and legal wife) Ghanima Atreides and her concubine Farad'n Corrino. Leto Atreides II's lack of a direct heir, coupled with his decision to dissolve the Atreides Empire after his 3,500 year-long life came to an end, saw House Atreides cease to exist as a tangible political power. However, Leto I was walking into a trap set up by a newly formed alliance between House Harkonnen and House Corrino.Īrrakis remained the home of House Atreides until its official end. However, the House was also proficient in war it maintained Swordmasters, Warmasters and Mentats to train and lead their army, and had even developed its own Battle Language.Īt the request of Padishah Emperor Shaddam Corrino IV, Leto I moved the House to planet Arrakis, to take over mining operations of the Spice Melange from House Harkonnen. Furthermore, House Atreides kept Caladan a lush, prosperous paradise with relatively low industrial levels, in stark contrast to House Harkonnen's capital, Giedi Prime. House Atreides had perfected a form of government that resulted in a well-organized society and a spiritually satisfied people. Up until the latter days of Duke Leto Atreides I, House Atreides maintained the planetary fief of Caladan and had their center of operation on the planet, which they had also ruled for twenty generations. This Royal House included many significant figures in Greek myth. The descendants of Atreus are called "Atreides" (plural "Atreidai", Latinized as "Atreidae") in the Greek language. House Atreides specifically claimed descent from King Agamemnon, a son of Atreus, in Greek mythology. The legend stated that the Atreides family came from a noble family that originated in Greece on Earth, and that they rose to prominence during the Butlerian Jihad.
