Dune Prior to the events of
Dune, Fenring serves as the Imperial Agent on
Arrakis during the
Harkonnen regime, and then as Governor of Arrakis during the handover period between House Harkonnen and
House Atreides. He is later the Siridar-Absentia of the Atreides homeworld of Caladan while the Atreides occupy Arrakis. In
Dune, the Harkonnens, secretly aided by the Emperor's fierce
Sardaukar warriors, destroy the Atreides forces and reclaim control of Arrakis. Fenring and Margot visit the Harkonnen homeworld of
Giedi Prime, where the Count informs Baron Harkonnen that Shaddam is displeased with the way the invasion of Arrakis was handled, and frustrated by his failure to suppress the disruptive native
Fremen population. Another epigraph by Irulan explains that "the measure of Count Fenring's friendship" with Shaddam is shown by both Fenring's efforts to conceal Shaddam's complicity in the Harkonnen invasion, and also his refusal of Shaddam's command to kill Paul. sometime between the events of the novels
Dune and
Dune Messiah (1969).
Paul of Dune Hasimir and Margot are raising Feyd and Margot's daughter — whom they have named
Marie — as their own in the Brian Herbert/Kevin J. Anderson novel
Paul of Dune (2008). Between the events of
Dune and
Dune Messiah (1969), the Fenrings train their young child as both an assassin and a Bene Gesserit, but reject the interference of the Sisterhood itself in favor of their own plans for Marie to seize the Imperial throne from Paul Atreides. Marie is accepted into Paul's court as a playmate for his young sister
Alia; at a banquet with her visiting parents, six-year-old Marie and the Fenrings execute their well-planned assassination attempt on Paul. Alia manages to kill Marie, but Margot's revelation of her daughter's paternity surprises Paul enough to allow Hasimir to stab him near-mortally. Paul's
concubine Chani uses the poisonous
Water of Life to help save him, and he lives; rather than kill the Fenrings, he banishes them to Salusa Secundus into permanent exile with Shaddam, whom they now loathe. ==In adaptations==
