SHEEANA

'Sheeana Brugh' is a fictional character in the Dune universe created by Frank Herbert. She appears in ''Heretics of Dune'' and ''Chapterhouse Dune'', the last two ''Dune'' novels written by Herbert, as well as the final novels in the saga, ''Hunters of Dune'' and ''Sandworms of Dune''.
Sheeana lives in the desert of the planet Dune, now known as Rakis, until her village — situated on top of a spice blow — is destroyed by a sandworm. Sheeana then unintentionally displays an ability to control sandworms when she causes the creature to stop harmlessly in front of her. The worm takes her to Keen (once Arrakeen), the capital city of Rakis, where she is soon recognized as the sandrider predicted by Leto II. She becomes the youngest Reverend Mother ever (with the possible exception of Alia Atreides, technically a Reverend Mother before birth). When Rakis is destroyed, Sheeana travels to Chapterhouse, where her abilities continue to develop. She becomes a full Reverend Mother but remains a very independent character with mysterious depths, such as reflected in the piece of art called 'The Void'. At the end of ''Chapterhouse Dune'' she chooses to escape Chapterhouse on the no-ship together with Duncan Idaho. When the no-ship has left Murbella realizes that Sheeana is going to be a bitter medicine for the universe, indicating that she is going to play an important role in the future.
