Daniel and Marty

Daniel and Marty are fictional characters from the Dune universe created by Frank Herbert. These mysterious observers with advanced technological powers are introduced in Herbert's 1985 novel Chapterhouse: Dune. Herbert's 1986 death "left fans with an über-cliffhanger" for twenty years, until his son Brian Herbert and author Kevin J. Anderson published two sequels to the original series, Hunters of Dune (2006) and Sandworms of Dune (2007). Based on notes left behind by Frank Herbert for his own seventh novel in the Dune series, the sequels reintroduce Daniel and Marty, and reveal Brian Herbert and Anderson's interpretation of the characters' true nature.
