Odrade is watching her no-ship prisoners, Duncan, Murbella, and Scytale, through com eyes. The ghola Miles Teg is with Duncan and Murbella, who are trying to restore the Teg Bashar’s memories. Odrade notes that she hasn’t heard from the Rabbi that was hosting Lucilla.
Bellonda wants to talk about the risk of a new sandworm population that could return the tyrant’s influence. However, the exponential growth of humanity has ended Leto II’s hold on their destiny. Odrade worries about the drain on their time and resources caused by the Scattering. She fears the Scattering is being tracked by secret sensors. Bellonda tells Odrade that she is causing unease in Chapterhouse; her actions are interpreted as indecision. The proctors are holding a vote of no confidence in her.
Odrade asks Bellonda to use her Mentat abilities to tell her what happened on Gammu, but Bellonda doesn’t have enough data. Gammu is an economic hub, but they don’t know why the Harbored Matres are holding onto it. The Bene Gesserit also suspect an alliance with another party. They entertain the idea of an attack to disrupt trade and commerce in the area.
Later, Odrade confers with Bellonda about using an attack to harry the Honored Matres on Gammu. They also discuss another Honored Matres stronghold on the planet Junction. After the vote, the proctors are still in support of her but only by one vote. Odrade considers that if they successfully restore Miles Teg’s memories, they will have to watch him carefully, and a no-ship might not be sufficient to contain him.
She wonders what makes the Honored Matres so reactive and violent and how they would react to defeat. They go to extremes.
Duncan Idaho is working with Miles Teg to help him recover his memory. He talks to him about the old Bashar Teg, reflecting on his memories of him and the warnings Odrade gave him before she entrusted Miles Teg to his care. Though Duncan is awakening old memories, he is also helping a new person form.
Odrade asks how Duncan’s memories were restored, and he tells her it was done by the original Bashar Teg. Duncan tells Miles Teg that the restoration of his original memories will be a painful experience both physically and mentally, as there are artificial ghola barriers around his original memories. He explains there is a particular difficulty restoring Miles Teg’s memories, as gholas usually have a memory of their original’s death that they can use to break these barriers, but Miles Teg’s cells were scraped and cloned before death. Duncan also tells Miles to be wary of the Bene Gesserit.
Murbella enters and says they won’t appreciate him saying this. She has come off the Honored Matres adrenaline drug entirely under Bene Gesserit training and feels loss as she realizes she can’t go back to the Honored Matres.
Duncan asks if Miles Teg has been told of Muad’Dib, as he is an Atreides. Duncan will show Miles Teg the Bashar Teg’s favorite picture of his home. Murbella notices that this diverges from the Bene Gesserit instructions of awakening original memories. Duncan leaves, seeking Sheeana, saying there must be a better way to restore the memories.
Duncan is on his console and finds an entry in it from early in his incarceration. He suddenly has a vision of an elderly couple that stretches across his ghola lifetimes; he doesn’t recognize them but knows they are face dancers.
The vision ends, and he is confronted by Murbella, who he tells about his vision. He curses the Tleilaxu for tampering with him.
Odrade is having her first spice of the morning. This is painful for her after overnight withdrawal. She is in her sleeping chamber waiting for it to take effect. She reflects on the reality of Bene Gesserit’s spice addiction. They don’t typically consider it such, but its effects shape every part of their life, and they can’t live without it.
She talks to Streggi about how unique spice is as a drug, increasing life rather than shortening it like many other drugs; the price, however, is addiction. She tells Streggi to go find Tamalane.
Odrade thinks about how Sheeana and Duncan want to speak to each other about Miles Teg. Creating the pain that will help Miles Teg recover his memories troubles Duncan.
Odrade sees a stack of records on her desk, part of the organization of the Scattering. She summons Bellonda, who explains that the records were judged significant. Odrade says that the sheer mass of records is sloppy work. She contacts Tamalane in the transport hall, asks how soon they can leave, and says she will be taking Streggi, too. Later, she learns from Tamalane there has been no word from Dortujla.
The Rabbi is sitting with Rebecca in a no-chamber buried under an ash pit. They are in hiding from the Honored Matres. They have been in the restrictive chamber for some time and may have to stay there. Rebecca thinks about the appeal of prescience as well as its cost. She thinks of Muad’Dib’s attempts to prevent the terrible things he’d seen coming.
A rainstorm is approaching and will make the ash in the ashpit set like concrete. If they need to get out, they will have to dig with tools.
Duncan thinks about Miles Teg’s education. It is carefully structured to echo the original Bashar Teg’s childhood. He thinks about the no-ship and how it is his prison, staffed by Reverend Mother guards. The Bene Gesserit are also studying it to figure out a way to nullify its no-ship cloaking.
He spends many hours trying to figure out the ship’s data stores, but it locks out of certain systems such as flight. He knows the systems well enough to hide his own data and booby trap it to delete itself should someone else try to access it.
For some time, he’s been aware that he could escape, but he stays because he is unable to bring Murbella with him. His data sources on the current situation with the Honored Matres has been deliberately stifled to hobble his Mentat abilities.
Meanwhile, Murbella is becoming more like a Bene Gesserit. The no-ship has become a place where the Bene Gesserit train Murbella to become one of them and help strengthen Duncan’s abilities. The Bene Gesserit intend to use Duncan’s sexual bonding abilities to control Sheeana for them. Murbella and Duncan talk about how their love is in contradiction with her aim to become a Reverend Mother.
Odrade travels into the desert with Tamalane and Streggi in a ground vehicle. The Honored Matres have destroyed four more planets, leaving the Bene Gesserit with only 12, a fact that Bellonda has been asked to keep secret. The desertification of the planet is progressing, and many plant species are under threat. Nothing can be done.
They arrive at Pondrille Tsimpay, and the head Bene Gesserit of this community comes out to meet them. There is some controversy about the desertification of the planet for the sandworms among the local farmers. They continue on, and Odrade mentors Streggi in her approach to history and morality. Odrade gets them to stop near the ocean. The sea has receded due to the climate change. Odrade gets the driver to bring the vehicle down to the sea so she can swim. While swimming, she instructs Tam to eliminate the sea as fast as possible. It is essential for the future of spice production.
Dama is in her new control center on planet Junction. She knows that Dortujla has returned to planet Buzzell and asks Logno to bring her in and to starve some Futars.
The Honored Matres are searching for Chapterhouse and closing in on it. She killed two Ixian scientists after they asked for more information on The Weapon. They were unsure of what The Weapon is and could not replicate it. Dama asks after Rebecca, who is in hiding; Logno is unable to locate her.
On her way to the no-ship, Bellonda reviews her assessment of Duncan’s many lives. His personality has subtly changed throughout his various incarnations, going from impulsive to cynical. She is fascinated by his long service to Leto II, where he had served as a Mentat in several lives and a truthsayer in others. This mix of skills and experience is something she sees as dangerous.
When she arrives in the no-ship, Duncan says that he was expecting her. Miles Teg enters and stands with Duncan. He is there to ensure that Bellonda doesn’t hurt Duncan, because if she does, Miles Teg will never cooperate with the Bene Gesserit. Bellonda accuses Duncan of conspiring with Sheeana. Bellonda and Duncan argue. He calls her a hypocrite, making her flinch. She initially thinks this is due to The Voice but realizes it is something deeper.
Bellonda tries to keep her composure for the com eyes, but Duncan berates her, questioning her value to the Bene Gesserit. This makes it hard for Bellonda to maintain her hold on Mentat mode.
He interrogates her on a variety of subjects from the risks of the Bene Gesserit Scattering to the idea that the Honored Matres may be a relatively small group fleeing into the old empire to recoup their strength. He also suggests that the Ixians may be developing cyborgs, something that disgusts Bellonda.
He goes to Murbella’s room and discusses the meeting with her, revealing to her the Missionaria Protectiva—the arm of superstition for the Bene Gesserit—are planning to build a religion around Sheeana.
Tamalane enters Odrade’s quarters in Eldio just before dawn. She says that the road ahead has been covered by large dunes and is impassible. Odrade orders the ornithopters—small transport vehicles commonly called ‘thopters—to drive to a nearby observation terminal shortly after breakfast. The desert is spreading rapidly across the planet, and Odrade realizes that soon she will have to relocate the population to the polar regions.
At the observation terminal, Odrade sees the vast expanse of the dunes and sand in the desert. A message arrives from Buzzell: Dortujla and the Reverend Mothers there have been taken by strangers. Odrade says the Honored Matres have taken the bait. The message was brought by a fleeing acolyte, and Odrade contacts Bellonda to check if the acolyte is ready for the Spice Agony so that she may become the Reverend Mothers’ messenger. She then instructs Bellonda to give Duncan open access to Archives. Tam reveals that Duncan and Sheeana have been in collaboration for some time.
The ‘thopters arrive and embark across the desert, landing at the Desert Watch Center. Sheeana arrives to meet Odrade. Odrade asks her about her collaboration with Duncan, which she admits to. Later, Sheeana tells Odrade that a spice mass has been spotted close to the Observation Center.
Odrade tells Sheeana that she may have to replace Tam soon. When Odrade departs, Sheeana reflects on a discussion she had with Duncan about imprinting Miles Teg to restore the Bashar’s memories. Imprinting requires a technique common to the Honored Matres that Sheeana also possesses; she must have sex with a partner to create a powerful psychological bond that gives her control over that partner.
This section explores the growing relationship between Duncan Idaho and ghola Miles Teg. Miles Teg is left in Duncan’s care with the aim of returning his memories, but Duncan quickly begins changing Miles Teg’s loyalties. Amid his imprisonment, Duncan has grown deeply critical of the Bene Gesserit and would’ve escaped if not for his bond with Murbella. Both Duncan and the original Bashar Teg symbolize loyalty, as they have served the Rakis emperors and the Sisterhood, respectively. Still, Duncan recognizes how circumstances have changed, and he understands The Importance of Change and Adaptation to Survival and considers this as he assesses the Bene Gesserit. This growing bond between Duncan and Miles Teg reflects the broader tensions of the novel—between loyalty and rebellion, tradition and adaptation. Duncan’s willingness to shape Miles’s future rather than simply restore his past mirrors his own quiet resistance to the Bene Gesserit’s rigid control. In both cases, survival depends not on returning to what was, but on forging something new.
Increasing tension, there is discussion of how to forcefully return Miles Teg’s memories through imprinting, which is equal to sexually assaulting him. The act of imprinting is accepted as being stressful enough to instigate the return of the Bashar Teg’s original personality. That this is under discussion shows the extreme lengths to which each primary character may be willing to go to ensure the furthering of their plans and their ultimate survival. This questionable moral calculus also underscores the increasingly blurred lines between the Bene Gesserit and the Honored Matres. Even as the Sisterhood condemns the Matres’s use of sexual domination, some of its members consider deploying similar methods for strategic gain. This hypocrisy—highlighted especially through characters like Sheeana, who possess imprinting abilities—reveals how adaptive survival may come at the cost of ethical clarity.
The idea of change looms over Odrade, who feels her control over the circumstances of her life and her order slipping. As she travels, observing the desertification of the planet, she witnesses the ocean receding. She swims, an experience that may be considered frivolous, but it plays into the needs of the Sea Child she holds inside her. The very landscape of Chapterhouse becomes a metaphor for Odrade’s internal struggle—a place being stripped of softness and fluidity to serve a harder, more strategic future. The natural world is sacrificed to ideology, just as Odrade is asked to sacrifice parts of herself for leadership. This experience demonstrates how Odrade clings to her personal needs, but she still sacrifices these desires for the cause of her people, as growing the desert and destroying the ocean is necessary for the sandworms to live. This is another example of The Connection Between Domination and Cultivation, as the Sisterhood have dominated Chapterhouse but are also cultivating something new to ensure their way of life. In this light, Odrade is not merely a pragmatic leader—she is a profoundly tragic figure, conscious of every loss incurred by survival. Her tenderness is not a weakness but a private reckoning with what their future demands.
Nonetheless, this builds on a moment of helplessness Odrade expressed in Chapter 18 when laying down to rest. She observes a Vincent Van Gogh painting on her wall, something epitomizing a sentimental affection for human art and passion: “‘Cottages at Cordeville.’ A better map than the one marking the growth of the desert, she thought. Remind me, Vincent, of where I came from and what I yet may do” (210). This symbol of her humanity only emphasizes her uncertainty about the morality and effectiveness of her actions. Despite having Other Memory, which literally allows her to see the past through others’ memories, she still seeks out an abstract version of ancient history for guidance. This blend of historical consciousness and aesthetic reflection shows how Odrade relies not only on inherited knowledge but on deeply felt cultural memory to navigate crisis. Her connection to Van Gogh—a symbol of emotion, madness, and artistic legacy—positions her as a leader torn between rational stewardship and human vulnerability.
Dama and the Honored Matres are less present in this section, with Dama continuing her critical contemplations through conversations with her prisoners. Dama is often positioned within the narrative to have her intellectual shortcomings on display, with the wisdom of the Reverend Mothers easily navigating her flawed logic. In her conversation with Dortujla, Dama guesses at the Sisterhood’s position on the risks of holding power, saying “I thought you would tell me something new. We know that one: ‘Power corrupts. Absolute power corrupts absolutely’” (197). This phrase came from a letter from 19th-century writer Lord Acton to an Anglican bishop, and its relevance far into the future shows its cultural significance; however, Dortujla disputes this. She replies, “Wrong, Dama. Something more subtle but far more pervasive is at work. We’ve said it often enough but few hear us. Power attracts the corruptible” (197). Dama reacts negatively to this ideology, which asserts that the only way for one to validate the purity of their intentions and remain uncorrupted is to avoid a high position of power. This loosely plays with the theme of Free Will and Prescience, which is ultimately a battle between fate and individual determination. Some may seek power convinced they have good intentions, but Herbert here implies this may be fundamentally impossible and that all quests of this nature are doomed from the start. Dortujla’s counterpoint reveals how the Bene Gesserit philosophy diverges sharply from traditional warnings about power. Rather than fearing corruption as an outcome, they assume it as a condition and build systems of checks and mentorship—like shared memory—to mitigate it. Dama’s inability to grasp this subtlety marks her as a leader who seeks power for certainty, not insight.
Across these chapters, discussions of transformation, hypocrisy, and control deepen. Duncan’s evolution from servant to skeptic parallels Odrade’s loosening grip on tradition and certainty. The Bene Gesserit’s pursuit of survival pushes them toward practices once unthinkable, including using sexual imprinting, building new religions, and manipulating memory. The desertification of Chapterhouse becomes not just an ecological process, but a symbol of cultural rebirth—harsh, irreversible, and tied to loss. With characters like Sheeana stepping into morally ambiguous roles and the reawakening of Miles Teg drawing nearer, this section foreshadows a final confrontation not just with the Honored Matres, but with the moral cost of institutional endurance.
