Marty/XD



Marty is an entity that appears in Duncan Idaho's visions, when the no-ship, the Ithaca, was being chased and trying to be encaptured by Daniel and Marty. Marty appears as a homely, elderly woman alongside her long-time male companion, Daniel.

Erasmus
Marty was a human guise worn by the reborn Thinking Machine Independent Robot, Erasmus. Throughout the centuries, Erasmus, and the Thinking Machine ruler, the reborn Omnius, had been absorbing personalities they have acquired from Enhanced Face Dancers.

It is this simple form of a non-threatening, human female, that Erasmus had chosen to communicate with many of his minions, and other humans, during the advent of Kralizec. The Face Dancer Myriad leader, Khrone, servant of the Machines, during this time could never quite understant why Erasmus would want to wear such a weak persona, when he was one of the most powerful entities in the Known Universe. This was the persona that the flow-metal machine decided to cease function and die in, after Idaho became the Ultimate Kwisatz Haderach.

Behind the Scenes
As the late Frank Herbert died in 1986, soon after the introduction of the characters of Daniel and Marty in Chapterhouse:Dune, other speculation has arisen as to other interpretations of whom the characters could have been.

Metaphors for Frank Herbert and Beverly Herbert
It was stated before by Brian Herbert 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.

Independent Face Dancer Theory
By the statements made by Marty and Daniel at the end of Chapterhouse: Dune, some have said that may have been Independent Face Dancers.
