So, a Guild Navigator shows up at the Emperor's house at the start of the movie and tells him to kill Paul Atreides.
Paul becomes the god Muad'dib at the end of the movie and vanquishes the Emperor, but the Guild Navigators are still the ones in charge of folding space, aren't they?
What is their relationship with Muad'dib at the point we get to at the end of the movie? I'd have thought that if the Guild Navigators still want Paul dead, they have many ways to make his life difficult.
I'm guessing this is dealt with in the books (assuming the movie is more or less canon with the books).
