In this episode, we take a look at chapters sixteen through eighteen of God Emperor of Dune, in which Leto and his attendants begin the decennial peregrination to Onn, Duncan and Leto reminisce about the old environment of Arrakis when it was still a desert known as Dune, the Bene Gesserit debate how to react to an unsettling move by the Tleilaxu, and Moneo manages to win a boon from the God Emperor - after a long and tense conversation during which "The Worm" lurked dangerously close to the surface.
