Spacing Guild
In addition to the Great Houses, which have their own Congress-like entity called the Landsraad, and the Corrino Imperium, which is ruled by a single emperor, Dune’s other major player is the Spacing Guild, a trade organization and navigation school that provides the pilots for interstellar travel. With complex computers outlawed following the Butlerian Jihad, ships rely on Spice-snorting pilots to calculate complex trajectories and get massive, faster-than-light fleets where they need to be. Though only mentioned in passing in the Dune movies, like when Paul threatens to cut off the entire Spice trade, it’s an important countervailing force to the rest of Dune’s political players.
