Dune

In the far future, the known universe is ruled by the Padishah Emperor Shaddam IV. The most valuable substance in the empire is the spice melange, which extends life and expands consciousness. The spice also allows the Spacing Guild to fold space, allowing safe, instantaneous interstellar travel. The Guild forces Shaddam to clarify a conspiracy that could jeopardize spice production forever. Shaddam reveals that he has transferred power and control of the planet Arrakis, the only source of the spice, to House Atreides, but once the Atreides arrive, they will be attacked by their archenemies, the Harkonnens, and Shaddam's own Sardaukar troops. Shaddam fears the Atreides due to a secret army that is reportedly being amassed by them.
