Schools of Dune

It is 83 years after the last of the thinking machines were destroyed in the Battle of Corrin, after Faykan Butler established himself as the first emperor of a new imperium. War hero Vorian Atreides has turned his back on Salusa Secundus, flying off to parts unknown. Abulurd Harkonnen, convicted of cowardice, was sent away to live on gloomy Lankiveil, and his descendants continue to blame Vor for the downfall of their fortunes.

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. Mother Superior Raquella attempts to rebuild her Sisterhood School on Wallach IX, with her most talented and ambitious student, Valya Harkonnen...who also has another goal - to exact revenge on Vorian Atreides.

Navigators, mutated by spice into beings far superior to normal humans, make space travel possible across the burgeoning Imperium. Their prescient awareness allows them to foresee safe paths through the universe as starship engines 'fold' space. Only industrial magnate Josef Venport knows the secret of creating Navigators, and he intends to build a commercial empire to span the galaxy.
