Margot, Lady Fenring is a fictional character from the Dune universe created by Frank Herbert. She is featured in Herbert's Dune (1965), and is a major character in the Prelude to Dune prequel trilogy (1999–2001) and the 2008 novel Paul of Dune by Brian Herbert and Kevin J. Anderson. She later appears in the Caladan Trilogy (2020–2022). Margot is the Bene Gesserit wife of Count Hasimir Fenring, a close friend of the Padishah Emperor Shaddam IV, but is loyal to the Sisterhood. Léa Seydoux will portray Margot in Denis Villeneuve's upcoming film Dune: Part Two. Description Margot is one of the Bene Gesserit, a secretive matriarchal order who have achieved superhuman abilities through mental and physical conditioning, and the use of the drug melange. Under the guise of humbly "serving" the Empire, the Sisterhood is in fact a major power in the universe, using its many areas of influence to subtly guide humanity along the path of its own plan for humanity's future. To this end, the Bene Gesserit install some of their initiates in noble families as wives and concubines to their advantage. Margot's Bene Gesserit abilities include acute observation and awareness, seduction and sexual imprinting, and precise control of her body chemistry, which allows her to ensure conception and choose the sex of the child. Despite general prohibitions against sharing Bene Gesserit skills with males, Margot has trained her husband Count Fenring in the acute observation practiced by the Sisterhood. Feyd-Rautha Harkonnen describes Margot in Dune: Appearances Margot appears in Herbert's novel Dune (1965), in which she warns fellow Bene Gesserit Lady Jessica of impending danger to the Atreides, and is later sent by the Sisterhood to visit Feyd-Rautha Harkonnen. Margot is also a major character in the Prelude to Dune prequel trilogy (1999–2001), the 2008 novel Paul of Dune, and the Caladan Trilogy (2020–2022) by Brian Herbert and Kevin J. Anderson.
