Spacing Guild
In "" (2001), the Spacing Guild plays the role of a subhouse. It has its own private army with which it can back up its demands. The Guild uses its Heighliners to transport troops from the various homeworlds to Arrakis. Later in the game,they become evil, building an "Emperor Worm" through which they hope to rule the Universe. Depending on which House you use, and whether or not you win or lose, the campaign end cutscenes are different.
