Dune - TV Edition Prologue
The prologue explains that mankind had become dependant on thinking machines and had falled into a state of apathy. This made it easy for people with machines to turn them into slaves. Eventually a Jihad ended this slavery and schools were created to develope the mind. The two reminding schools are the Bene Gesserit and the Spacing Guild.
The prologue then describes the relationship between the Guild, the CHOAM, the Emperor and the Houses of Atreides and Harkonnen.
