10191. The known universe is ruled by the Padishah Emperor Shaddam the
Fourth, my father. In this time, the most precious substance in the
universe is the spice Melange. The spice extends life. The spice
expands consciousness. The spice is vital to space travel. The Spacing
Guild and its navigators, who the spice has mutated over 4000 years,
use the orange spice gas, which gives them the ability to fold space.
That is, travel to any part of the universe without moving. Oh, yes. I
forgot to tell you. The spice exists on only one planet in the entire
universe. A desolate, dry planet with vast deserts. Hidden away within
the rocks of these deserts are a people known as the Fremen, who have
long held a prophecy that a man would come, a messiah, who would lead
them to true freedom. The planet is Arrakis, also known as Dune.
