SciFi Tech Talk #000063 - Dune

Set in the far future amidst a feudal interstellar society in which noble houses, in control of individual planets, owe allegiance to the imperial House Corrino, Dune tells the story of young Paul Atreides, the heir apparent to Duke Leto Atreides as his family accepts control of the desert planet Arrakis, the only source of the "spice" melange. Melange is the most important and valuable substance in the universe, increasing Arrakis' value as a fief. The story explores the multi-layered interactions of politics, religion, ecology, technology, and human emotion, as the forces of the empire confront each other in a struggle for the control of Arrakis and its "spice". - Wikipedia.org
