The Bene Gesserit become the consumers of Idaho gholas in Heretics of Dune (1984) and Chapterhouse Dune (1985). However, the Tleilaxu keep killing the gholas after several years. Not knowing exactly what purpose Idaho will serve, the Bene Gesserit suspect 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 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 bond Idaho, 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 bond Duncan, the Tleilaxu's plan comes to fruition, and he becomes aware of the memories of all the other Idaho gholas. The two of them are confined to a no-ship on 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 old man and woman staring back at him. Duncan restores the memories of the Miles Teg ghola, and escapes in the no-ship, evading the trap set for him by the strange couple.
[edit]Sequels
Brian Herbert and Kevin J. Anderson continued from the original series with Hunters of Dune (2006) and Sandworms of Dune (2007), originally planned to be Dune 7 by Frank Herbert. Duncan continues his travels on the no-ship, now named the Ithaca by its passengers. He is accompanied by Miles Teg, Sheeana and a group of her Bene Gesserit sisters, the last Tleilaxu Master Scytale, and many others.
Duncan and the other refugees from Chapterhouse are still on the run from the Unknown Enemy that hunts them. They don't learn until near the end that the Enemy is the revived empire of thinking machines, and the old couple are actually the computer-entity Omnius and the robot Erasmus. In the final confrontation with Omnius, Paul Atreides (brought back as a ghola and with his power of prescience just-now restored), and then Norma Cenva (the Oracle of Time to the Navigators), both reveal that Duncan is the Ultimate Kwisatz Haderach; not Paul nor any other Atreides, nor their descendants. Overwhelmed by the unexpected revelations, Duncan decides to unite humanity and the thinking machines—after Cenva permanently removes Omnius from existence—rather than bring about the absolute destruction of intelligent technology for the second time in history.
Assuming the responsibility of mediator between the two sides, and with Erasmus' willing participation (the robot being left as the leader and controlling-force of the thinking machines), Duncan does something similar to Bene-Gesserit Sharing with the robot; possibly along with what seems to be a physical-bonding (similar to what Leto II did with the sandtrout) into something of a human-machine hybrid. Erasmus then voluntarily "dies", while remaining an Other Memory speaking to Duncan. In addition to being the Final Kwisatz Haderach of the humans, Duncan becomes the new evermind of the thinking machines, guiding their joint future.
