In the far future, the known universe is ruled by Padishah Emperor Shaddam IV. The most valuable substance in the empire is the Spice, a drug that extends life and expands consciousness. The Spice also allows the Spacing Guild to fold space, permitting safe, instantaneous interstellar travel.
The Guild fears a conspiracy that could jeopardize spice production and sends an emissary to demand an explanation from the Emperor, who reveals his scheme to destroy House Atreides. The Emperor fears Duke Leto Atreides's growing popularity — and a secret army he is reportedly amassing — threaten his rule. He plans to cede control of planet Arrakis, the universe's only source of Spice, to House Atreides. Once they are installed there, the Atreides will be ambushed by their archenemies, the Harkonnens, with help from the Emperor's elite Sardaukar troops.
