Arrakis
Since Spice can only be found on Arrakis, the desert planet is constantly in a state of turmoil. Dune’s political empire, the Corrino Imperium, relies on individual houses to harvest spice from the planet’s surface, but the threat of worms and attacks by the indigenous Fremen mean the honor also comes with a lot of costs. Whoever is supposed to be in charge of the planet gets a ton of spice but is also constantly getting attacked and killed.
This makes Arrakis a consistent pain point in Dune’s delicate political order. In the movies, the planet becomes a staging ground for Paul Atreides rebellion against the Imperium and his messianic journey to terraform it into a paradise that would destroy all spice in the process. At the start of Dune: Prophecy, as in the start of the movies, the big question is how to get the military resources together to subdue Arrakis.
