Navigators of Dune

Humans claim that deep personal tragedy can cause severe changes in mindset. I have experimented with these effects in my studies of laboratory subjects, inflicting damage to people and testing their reactions. Yet I was never able to verify the hypothesis through direct experience—until the death of Gilbertus Albans.

—ERASMUS, Secret Laboratory Notebooks

Inside the Denali laboratory domes, Directeur Venport’s researchers worked on vital projects, hidden in the poisonous atmosphere of the isolated planet. The scientists had been recruited based on their intellect as well as their hatred of the Butlerians.

Now the research teams regarded the Erasmus memory core with fascination, calling him a priceless trove of historical experiences—which pleased the independent robot. At long last, Erasmus found himself among like-minded persons, and he reveled in the attention.

Draigo Roget had rescued his memory core when the fanatics overthrew the Mentat School. Erasmus appreciated the man’s efforts in saving his life, just as Gilbertus had saved him decades earlier. Erasmus had owed much to his human ward Gilbertus. The robot had raised a feral child from the slave pens and shaped him into a nearly perfect human being. And those irrational barbarians killed him! Defeated, Gilbertus had simply bowed to the thuggish Swordmaster Anari Idaho, who then hacked off his head with her sword.

Erasmus had simulated emotions in his programming, but this personal experience, this sense of terrible loss, had been far greater than anything he had previously recorded.

Now, in a well-lit research chamber against the poisonous gloom outside, his gelsphere core rested on a stand, connected to an imperfect sensory apparatus. Lovely young Anna Corrino, sister of the Emperor, hovered beside the memory sphere, while curious Denali scientists gathered close, hanging on the robot’s words, waiting for him to continue.

Erasmus realized that with his thoughts about Gilbertus, he had lapsed into silent anger. Yes … the human emotion of anger. He reviewed the unique experience in the same way he gathered all interesting data, particularly psychological data in his constant attempt to comprehend the complex human mind.

“I have much information to convey to you,” he said to Anna. “Highly useful information. If I can help you destroy the enemies of reason, I will do so.”

The violent, unnecessary, and confusing death of Gilbertus had changed mental paths in his gelcircuitry. Normally, he would have delighted in receiving new revelations, but the loss of his friend had not pleased him. Not in any way.

“Tell them about the Mentat School,” suggested Anna, smiling in her eagerness. The young woman’s small blue eyes and her quirky personality reminded Erasmus of stained glass, disjointed colors and distorted images. After her brain had been damaged by psychotropic poison at the Sisterhood school, Anna had become skittish, intense, and unpredictable. Her mind had never been the same afterward, and her concerned brothers had sent her to the Mentat School for treatment. There, Erasmus had found her, and made her into his most interesting human subject. He had guided the damaged young woman, manipulated her mind, helped her … but although he had tried to make her fit a perfect mathematical model, his work had not been a complete success.

“I spent many decades hidden at the Mentat School,” Erasmus said, “as Gilbertus Albans taught his students how to organize their thoughts.” His erudite voice was piped through speakers mounted around the room. He remembered what his original voice had been like in his flowmetal body. How glorious he had been back in the heady days of the Synchronized Empire, before the rampant humans wrecked everything … as they had done later at the Mentat School. One could not depend on humans to behave in an organized, rational fashion.

But Erasmus had the capacity to think in the long-term, and he was finally among allies now—those with the potential to cause retaliatory damage. They were all united in their desire to eradicate the Butlerian disease.

“Gilbertus hid my memory core for my own protection. He knew that if I were ever discovered, I would surely be destroyed. Unlike you like-minded people of Denali, others in the Imperium would never accept the benefits of my knowledge. They destroy what they don’t understand.”

Anna fidgeted as she moved about the chamber. Her voice sounded husky, as if overwhelmed with misplaced emotion. “If Erasmus had been destroyed, then billions of people would never learn how brilliant he is! How admirable he is.”
