Daniel

Daniel is an entity who appeared in Duncan Idaho's visions. The character appeared as a homely elderly man alongside his companion Marty.

By the statements made by Marty and Daniel at the end of Chapterhouse: Dune it is implied that they are independent Face Dancers. However, in the later Dune sequels written by Brian Herbert and Kevin J. Anderson, Marty and Daniel are revealed to be representations of ancient artificial intelligences Erasmus and Omnius. It is unknown whether or not Frank Herbert himself actually ever intended this, given that his final novel implies them to be advanced Tleilaxu creations.

Analysis
Brian Herbert has said that the characters Daniel and Marty created by Frank Herbert could be a metaphor for how he and Beverly Herbert had been watching the events in the Dune Universe unfold.
