Editing Duncan Idaho (section)

===''Heretics of Dune'' and ''Chapterhouse: Dune''===
The Bene Gesserit become the consumers of Idaho gholas in ''[[Heretics of Dune]]'' (1984) and ''Chapterhouse: Dune'' (1985).  However, the gholas are repeatedly assassinated after several years, and the Sisterhood suspect the Tleilaxu. Not knowing exactly what purpose Idaho will serve, the Bene Gesserit believe that the Tleilaxu are using the gholas to control the timing of his release upon the universe, implying some Tleilaxu purpose in addition to their own.  The current ghola survives such an attempt and [[Miles Teg]] is able to restore the memories of Duncan Idaho to the ghola, but Duncan can feel that the Tleilaxu planted something else in his mind. When [[Murbella]], an [[Honored Matre]], tries to sexually bind Idaho to her, he entraps and enslaves her, revealing the Tleilaxu purpose: to conquer the Honored Matres by using a better version of their own sexual techniques. When Murbella tries to enslave Duncan, the Tleilaxu's plan comes to fruition, and he becomes aware of the memories of all the other Idaho gholas, though he is also imprinted to her. It is later determined that the Tleilaxu had mixed the cells from almost all of the Idaho gholas to make this one. Idaho and Murbella are confined to a [[no-ship]] on [[Chapterhouse (Dune)|Chapterhouse]].  There, Idaho trains young men to go out into the universe and enslave Honored Matres.  Duncan also inherits an awkward prescient vision, wherein he sees an [[Daniel and Marty|old man and woman]] staring back at him. Duncan retrieves the Miles Teg ghola, and Sheeana Burg who escape in the no-ship, evading the trap set for him by the strange couple.
