Yeah, the first book sets it up but it is critical of the concept of charismatic leaders who claim they’re the ‘chosen one’. That ‘prophecy’ is orchestrated by a secret organization who influences the politics of that universe. The storyline still follows the family of the main character in the second and third books, as well as two other ruling families. The second book is more like a political family drama, then the third book is heavy with philosophy and supernatural elements within the Dune universe.
