Schools of Dune

It is 83 years after the last thinking machines were destroyed in the Battle of Corrin, after Faykan Butler took the name of Corrino and established himself as the first Emperor of a new Imperium. The war hero Vorian Atreides has turned his back on politics and Salusa Secundus. The descendants of the disgraced Abulurd Harkonnen have sworn vengeance against Vor, blaming him for the downfall of their noble family.

In Brian Herbert and Kevin J. Anderson's Mentats of Dune, the thinking machines have been defeated but the struggle for humanity’s future continues. Gilbertus Albans has founded the Mentat School, a place where humans can learn the efficient techniques of thinking machines. But Gilbertus walks an uneasy line between his own convictions and compromises in order to survive the Butlerian fanatics, led by the madman Manford Torondo and his Swordmaster Anari Idaho.

The story line tells the origins of the Bene Gesserit Sisterhood and its breeding program, the human-computer Mentats, and the Navigators (the Spacing Guild), as well as a crucial battle for the future of the human race, in which reason faces off against fanaticism. These events have far-reaching consequences that will set the stage for Dune, millennia later.
