In this episode, we take a look at chapters twenty-five through twenty-seven of Heretics of Dune, in which Odrade leads Tylwyth into the desert to witness Sheeana summoning a sandworm, tensions rise between the no-globe inhabitants as Duncan rebuffs the Imprinter's advances, Burzmali puzzles out where to look for Miles and is sent back to Gammu to pursue this theory, and Sheeana successfully commands a sandworm to allow her party to take a ride on its back…and it promptly takes off into the desert for parts unknown, as they make history as the first new sandriders in a particularly nerve-wracking way.
