Then Anna slipped out of her analytical state. “Why do you ask so many questions? Aren’t you a memory inside my head? You should know all of this.”

“I am your friend, and friends talk with each other.” Erasmus thought of how Gilbertus had been his loyal and worshipful student, how the two of them had talked at great length, played pyramid chess until late hours, and studied the results of experiments on various human subjects. “Whatever you have to say, Anna, I will find it fascinating. You are a most intriguing—” He caught himself before he said specimen. Instead, he said, “—young woman. I want you to be my special protégée.”

He thought of the swamp dragon the Mentat trainees had dissected. Someday, if Erasmus ever got a new body so he could handle tools and equipment, perhaps he would study Anna’s brain more closely, cutting it apart and deconstructing it in order to help her … or at least in order to learn more about the human mind in general.

“I want to be a friend like you’ve never had.”

She caught her breath. “I have always wanted that.”

Anna continued talking about her brothers, and about Lady Orenna, whom she viewed as a true mother-figure. She told him how much she missed the palace on Salusa and her special retreat in the tangles of a fogwood tree.

Partway through one of her stories, Anna began to sob. Erasmus could have offered her simple platitudes to make her feel better, but he remained silent, while continuing to observe closely. Better to let this moment play out, so he could study where it would go.

Yes, she was a unique and fascinating young woman, and he could envision her brain cut wide open on a laboratory table.

The traitor Dorotea and her orthodox Sisters had split from Raquella’s teachings because they refused to accept any form of advanced technology, regardless of the need. It was her blind spot, Valya knew. While pretending to be Dorotea’s friend, Valya had noted a disturbing edge of unreason in the other woman’s eyes and comments. During a years-long assignment on Lampadas to observe the Butlerian movement, Dorotea had been poisoned by their beliefs.

It was no wonder Dorotea had let her emotions get the best of her, turning like a viper against the Sisterhood.

Unlike the orthodox Sisters, Valya did not despise advanced technology: It was a tool to be used for her own purposes and for the success of the Sisterhood’s goals. Given the vast complexity of the breeding-record computers and their capacity for predictive analysis, she grasped the necessity for those tamed thinking machines. Besides, those exhaustive databases had allowed her to track down Atreides bloodlines. Technology was a means to an end, and Valya would use any weapon available to achieve her goals, which were far more important than any esoteric moral challenge.

While Butlerians stormed across the Imperium and destroyed anything that resembled a thinking machine, Venport Holdings promoted technology for the benefit of the human race. Now Cioba Venport arranged to transport Valya’s team to Rossak in secret so they could retrieve the buried computers. A loyal Sister, Cioba knew not to ask questions.

As their camouflaged shuttle dropped out of a huge VenHold spacefolder, guided down by a skilled Sisterhood pilot, Valya sat among fifteen women who had demonstrated combat proficiency in test exercises on Wallach IX, specially cleared Sisters from Raquella’s most trusted inner circle. Some of the commando Sisters were armed, and all of them were weapons in their own right. There was a chance they might have to face Imperial soldiers the Emperor had left behind to watch over the abandoned cliff city. If that happened, Valya was confident her Sisters could still prevail, but it would be better if they managed to slip in and out of the jungles without being noticed. She preferred not to have to explain bodies.…

Sister Olivia, one of the recently graduated Sister Mentats, selected a seat next to Valya as the shuttle descended through the atmosphere. “I spent a year on Rossak before going to Lampadas for Mentat training. It will be sad to see our great cliff city abandoned.”

Olivia was young and wide at the hips, with long blond hair and an assertive personality that Valya found grating at times, perhaps because it reminded her of herself. Olivia had formed a solid friendship with Fielle in their time together at the Mentat School, and Valya gauged the influence of all the new Sister Mentats. Fielle in particular was a shining star who already held much of the Mother Superior’s attention. Valya was keeping a close eye on her, assessing whether she would be a powerful ally or rival.

“Stay near me at all times,” she warned Olivia. “The shuttle will land far from any Imperial military defenses, and we’ll make our way through the thickest wilderness. It’s a testing ground, and there are many hazards for the unwary.”

The Sister Mentat gave her an indulgent smile, but quiet anger simmered beneath her controlled expression. “I’m not unwary, nor a fool. And the Lampadas swamps have ferocious predators as dangerous as any Rossak can offer.”

Valya realized that she herself should attempt more finesse. Even before becoming a Reverend Mother, she had observed many subtle connections in the political and personal web of Sisters — factions, alliances, rivalries, resentments, all under the guise of formalized teaching and philosophical debate. But that had changed when the Sisterhood itself split apart. Now, Valya vowed, she would help the true Sisterhood on Wallach IX to be strong, unified, focused.

And since the Mother Superior would have to name her successor soon, Valya needed to make certain the old woman made the correct decision. Valya felt envious when Raquella was with Fielle or when she showed interest in other Sisters — but voices in Valya’s mind, wise voices from Other Memory, counseled her to rise above such pettiness, for the sake of the Sisterhood and its mission to improve mankind. Valya had heeded such advice, but turned a deaf ear when the same voices suggested that she abandon her ambitious goals for House Harkonnen, so she could focus entirely on the Sisterhood.

Valya herself was absurdly young, in physical years, to be considered for such a monumental role. But for a Reverend Mother, with countless generations of experiences inside her, physical age was irrelevant. Her drive and determination, though, were her own.

If she became the Mother Superior, she would need to lead all of the Sisters, from the freshest acolyte like Tula to the wisest Reverend Mother. She couldn’t let Raquella see her act petulantly or childishly. She had to forge alliances, not break them. Their true enemies were the orthodox Sisters on Salusa and the betrayer Dorotea.

Now, she suppressed her feelings of antipathy toward Fielle and considered the good in the other young woman. Fielle was talented, but so new and untested that she could not possibly be Raquella’s replacement. For Valya to keep herself paramount in Raquella’s mind, and to demonstrate that she was rising above pettiness, the best solution was to turn Fielle into an ally, perhaps through her friend Olivia.

After a moment of assessment and consideration, Valya smiled warmly and said to Olivia, “You are part of my team for a good reason. In addition to the jungle hazards, we have to watch for any Imperial troops Salvador left behind. As a Sister Mentat, you might be able to see dangers that even I don’t detect. We have to make this a swift and smooth mission.”

Olivia seemed relieved. All the tense muscles in her face relaxed. “Our work here is vital for the Sisterhood. Each of us is an important member of the team.”
