Heretics of Dune - Plot Summary

Plot Summary

Much has changed in the millennium and a half since the death of the God Emperor. Sandworms have reappeared on Arrakis (now called Rakis) and renewed the flow of the all-important spice melange to the galaxy. With Leto's death, a hugely complex economic system built on spice collapsed, resulting in trillions leaving known space in a great Scattering. A new civilization has risen, with three dominant powers: the Ixians, whose no-ships are capable of piloting between the stars and are invisible to outside detection; the Bene Tleilax, who have learned to manufacture spice in their axlotl tanks and have created a new breed of Face Dancers; and the Bene Gesserit, a matriarchal order of subtle political manipulators who possess superhuman abilities. However, people from the Scattering are returning with their own peculiar powers. The most powerful of these forces are the Honored Matres, a violent society of women bred and trained for combat and the sexual control of men.

On Rakis, a girl called Sheeana has been discovered who can control the giant worms. The Bene Gesserit intends to use a Tleilaxu-provided Duncan Idaho ghola to gain control of this sandrider, and the religious forces of mankind who they know will ultimately worship her. The Sisterhood have subtly been altering the gholas to bring their physical reflexes up to modern standards. The Bene Gesserit leader, Mother Superior Taraza, brings Miles Teg to guard the new Idaho. Taraza also sends Reverend Mother Darwi Odrade to take command of the Bene Gesserit keep on Rakis. Odrade is a loose cannon; she does not obey normal Bene Gesserit prohibitions about love, and is also Teg's biological daughter. Bene Gesserit Imprinter Lucilla is also sent by Taraza to bind Idaho's loyalty to the Sisterhood with her sexual talents. However, Lucilla must deal with Reverend Mother Schwangyu, head of the ghola project but also the leader of a faction within the Bene Gesserit who feel gholas are a danger.

Above the planet Gammu, Taraza is captured and held hostage by the Honored Matres aboard an Ixian no-ship. The Honored Matres insist Taraza invite Teg to the ship, hoping to gain control of the ghola project. Teg manages to turn the tables on the Matres, and rescues the Mother Superior and her party. An attack is then made on Sheeana on Rakis, which is prevented by the intervention of the Bene Gesserit. Odrade starts training Sheeana as a Bene Gesserit. At about the same time an attempt is made on the life of Idaho, but Teg is able to defeat it. Teg flees with Duncan and Lucilla into the countryside. In an ancient Harkonnen no-globe, Teg proceeds to awaken Idaho's original memories, but does so before Lucilla can imprint Duncan and thus tie him to the Sisterhood. In the meantime, Taraza has been searching for Teg and his party, and finally establishes contact. During the operation, however, Teg and his companions are ambushed. Teg is captured while Lucilla and Duncan escape. Teg is tortured by a T-Probe, but under pressure discovers a new ability: he is able to speed up his physical and mental reactions, which enables him to escape. At the same time, Idaho is ambushed and taken hostage.

Taraza arranges a meeting with the Tleilaxu Master Waff, who is soon forced to tell her what he knows about the Honored Matres. When pressed on the issue of Idaho, he also admits that the Bene Tleilax have conditioned their own agenda into him. As the meeting draws to a close, Taraza accidentally divines that Waff is a Zensunni, giving the Bene Gesserit a lever to understand their ancient competitor. She and Odrade meet Waff again on Rakis. He tries to assassinate Taraza but Odrade convinces him that the Sisterhood shares the religious beliefs of the Bene Tleilax. Taraza offers full alliance with them against the onslaught of forces out of the Scattering. This agreement causes consternation among the Bene Gesserit, but Odrade realizes that Taraza's plan is to destroy Rakis. By destroying the planet, the Bene Gesserit would be dependent on the Tleilaxu for the spice, ensuring an alliance.

Lucilla arrives at a Bene Gesserit safe house to discover it has been taken over by Honored Matres, who have Idaho as their captive. As Lucilla infiltrates it, the young Honored Matre Murbella proceeds to seduce the captured Idaho with the Honored Matre imprinting method. However, hidden Tleilaxu conditioning kicks in, and Duncan responds with an equal technique, one that overwhelms Murbella. Lucilla takes advantage of Murbella's exhaustion to knock her unconscious and rescue Duncan. The Honored Matres attack Rakis, killing Taraza. Odrade becomes temporary leader of the Bene Gesserit before escaping with Sheeana into the desert on a worm. Teg also goes to a supposed safe house, only to discover the Honored Matres. He unleashes himself upon the complex, before capturing a no-ship and locating Duncan and Lucilla. They and the captured Murbella are taken to Rakis with him. When they arrive, Teg finds Odrade and Sheeana and their giant worm. He loads them all up in his no-ship, finally leading his troops out on a last suicidal defense of Rakis, designed to attract the rage of the Honored Matres. The Honored Matres attack Rakis, destroying the planet and the sandworms — except for the one the Bene Gesserit escape with. They drown the worm in a mixture of water and spice, turning it into sandtrout which will turn the secret Bene Gesserit planet Chapterhouse into another Dune.
