Sheeana
Sheeana Brugh is a young girl native to the planet Rakis who unintentionally displays a unique ability to control sandworms after her village is destroyed by one in Heretics of Dune (1984). She commands the giant creature to stop harmlessly in front of her, and then to take her to the capital city of Keen. Sheeana is soon recognized as the "sandrider" predicted by the God Emperor Leto II, and worshipped by the priesthood of Rakis. As she matures to adulthood, Sheeana effectively assumes control of the priesthood; her popularity and religious aura have increased both on and off Rakis, and the priests, believing her a prophet, are compelled to follow even her most unorthodox commands. The Bene Gesserit — who have their own plans for Sheeana and have secretly guided her education — thwart an assassination attempt on her, and unofficially take control of Sheeana, the priesthood, and Rakis. Reverend Mother Darwi Odrade begins Sheeana's formal Bene Gesserit training, and Mother Superior Taraza is soon pleased with Sheeana's progress, and considers a secondary plan of seeding other planets with sandworms with Sheeana's help.
Rakis itself is destroyed by the Honored Matres at the end of Heretics of Dune; in Chapterhouse: Dune (1985), Sheeana is now in charge of the project to breed sandworms on the Bene Gesserit world Chapterhouse. She becomes a full Reverend Mother but remains very independent, with mysterious depths. Disagreeing with the plans of new Bene Gesserit leader Murbella, at the end of Chapterhouse Dune Sheeana chooses to escape Chapterhouse on a no-ship with the Duncan Idaho ghola.
In Hunters of Dune, the 2006 sequel to Chapterhouse Dune by Brian Herbert and Kevin J. Anderson, Sheeana and Duncan lead the no-ship in their journey to flee the Unknown Enemy that pursues them. Sheeana decides that they need to make new gholas of former heroes using the genetic material carried by the last Tleilaxu Master Scytale. The story concludes in Sandworms of Dune (2007).
