Dune Messiah
by Frank Herbert
Twelve years after the events described in Dune (1965), Paul "Muad'Dib" Atreides rules as Emperor. By accepting the role of messiah to the Fremen, Paul had unleashed a jihad which conquered most of the known universe. Paul is the most powerful emperor ever known, but is powerless to stop the lethal excesses of the religious juggernaut he has created. Although 61 billion people have perished, Paul's prescient visions indicate that this is far from the worst possible outcome for humanity. Motivated by this knowledge, Paul hopes to set humanity on a course that will not inevitably lead to stagnation and destruction, while at the same time acting as ruler of the empire and focal point of the Fremen religion.
The Bene Gesserit, Spacing Guild, and Tleilaxu conspire to dethrone Paul, and the Guild Navigator Edric is able to shield the plot from Paul's prescient visions. The Bene Gesserit Reverend Mother Mohiam has enlisted Paul's own consort Princess Irulan, daughter of the deposed Padishah Emperor Shaddam IV. Paul has refused to father a child with Irulan (or even touch her), but his Fremen concubine Chani has also failed to produce an heir, causing tension within his monarchy. Desperate both to secure her place in the Atreides dynasty and to preserve the Atreides bloodline for the Bene Gesserit breeding program, Irulan has secretly been giving contraceptives to Chani. Paul is aware of this fact, but has foreseen that the birth of his heir will bring Chani's death, and does not want to lose her. The Tleilaxu Face Dancer Scytale gives Paul a gift he cannot resist: a Tleilaxu-grown ghola of the deceased Duncan Idaho, Paul's childhood teacher and friend, now called "Hayt". The conspirators hope the presence of Hayt will undermine Paul's ability to rule by forcing Paul to question himself and the empire he has created. Furthermore, Paul's acceptance of the gift weakens his support among the Fremen, who see the Tleilaxu and their tools as unclean. Chani, taking matters into her own hands, switches to a traditional Fremen fertility diet, preventing Irulan from being able to tamper with her food, and soon becomes pregnant.
Otheym, one of Paul's former Fedaykin death commandos, reveals evidence of a Fremen conspiracy against Paul. Otheym gives Paul his dwarf Tleilaxu servant Bijaz, who like a recording machine, can remember faces, names, and details. Paul accepts reluctantly, seeing the strands of a Tleilaxu plot. As Paul's soldiers attack the conspirators, others set off an atomic weapon called a stone burner, purchased from the Tleilaxu, that destroys the area and blinds Paul. By tradition, all blind Fremen exile themselves in the desert. But Paul shocks the Fremen and entrenches his godhood by proving he can still see, even without eyes. His oracular powers have become so developed that he can foresee in his mind everything that happens, as though his eyes still function. By moving through his life in lockstep with his visions, he can see even the slightest details of the world around him. Bijaz, an agent of the Tleilaxu, uses a specific humming intonation to implant a command that will compel Hayt to attempt to kill Paul under certain circumstances. Chani dies in childbirth, and Paul's reaction to her death triggers Hayt, who attempts to kill Paul. Hayt's ghola body reacts against its own programming and Duncan's full consciousness is recovered, simultaneously making him independent of Tleilaxu control.
Paul and Chani's newborn twins are "Leto and Ghanima. Duncan notes the irony that Paul and Chani's deaths have enabled them to triumph against their enemies, and that Paul has escaped deification by walking into the desert as a man, while guaranteeing Fremen support for the Atreides line.
