They are deeply involved in a long-term breeding program aimed at creating a superbeing. The Bene Gesserit are still grappling with the legacy of Leto II, the God Emperor, who ruled as a tyrant for thousands of years and transformed the ecology of Arrakis.

  6. The Golden Path and the Future of Humanity: The concept of the Golden Path, a vision for the future of humanity laid out by Leto II, remains a central theme. Characters grapple with the implications of this vision, which aims to ensure the survival and evolution of humanity.
  7. Climax and Resolutions: The story culminates in a series of climactic events involving Sheeana, the sandworms, and the various factions. These events set the stage for future books, leaving readers with questions about the direction humanity will take.
