Mentats of Dune

Then the Swordmaster had lopped off his head, extinguishing a fine and efficient mind.

Upon seeing the death of his student, his protector, and his friend, a jolt had gone through the robot’s gelcircuitry — a blinding flash that made him unable to process for a moment. In what seemed like an eternity, everything changed for Erasmus, as if the fundamental laws of reality had become different. He had not expected this at all.

Erasmus had seen countless humans die in the centuries of his life, many of them at his own hands, but he had never previously felt anything similar to this. Gilbertus was gone! The companion who had been such an interesting debater, such an avid learner, such a … such a caring, protective friend. Gone. Dead. Murdered! This could not be repaired. Gilbertus could not be replaced. Erasmus had never before experienced such a sharp, painful loss.

Something shifted in his malleable programming. Erasmus could not be cool and objective; rather, he felt dismay, disgust, and anger. And then with a cascade of realizations, data linking to data, he had another epiphany, a completely unexpected insight, another breathless revelation. He had an answer that he had been trying to find for more than two centuries.

Was this what had driven Serena Butler into such an irrational, hateful rage when he threw her noisy, crying child off a balcony? Incandescent, helpless rage and loss? Now he thought he grasped what had produced her immediate blind reaction. It all made sense in a way that it never had before. He understood the spark that had ignited the Jihad, with all of its tremendous consequences.

Gilbertus was gone. The Butlerians had killed him. His mind surged with countless reactions, all of them dark, violent, vengeful.

And now he brought those feelings with him to Denali.

Although Erasmus kept track of the different factions of humanity, especially the machine sympathizers and antitechnology fanatics, he now experienced actual loathing and hatred toward the people who had harmed the human who had become the equivalent of a son to him.

Yes. From all of his studies, that must be the sensation he was experiencing. Hatred. Along with unquantifiable sadness at watching the blood spill out and Gilbertus’s headless body collapse to the ground.

Erasmus despised Manford Torondo. Erasmus grieved for Gilbertus, who had given his life to preserve his beloved school. Those violent savages had destroyed it all. Erasmus felt strong resentment at the unfairness of the situation. Unfairness. These new thoughts and emotions were fascinating to him, and quite unpleasant. They threatened to overwhelm his circuitry.

Gilbertus was dead! And the robot decided he would have to do something about that.…

“This is not a pleasant world,” Draigo cautioned, “quite unlike the Imperial capital on Salusa. And dangerous, with a poisonous atmosphere — you can’t go outside the domes without special protective gear.”

“I’ll be fine,” she said, “as long as I can stay with Erasmus.”

During their journey, the robot had reviewed his stored memories of Gilbertus Albans, and had made projections of his growing friendship with A

When the ship settled onto the landing zone outside the reconstructed hangar dome, Erasmus was overjoyed to see the welcoming party that emerged to meet them. A

Four cymek walkers strode toward the shuttle, armored warrior forms like giant mechanical crabs, with pistons pumping and strong legs driving them forward. They were powerful, ominous, threatening — absolutely wonderful!

Erasmus hadn’t seen cymeks for a long time, and these appeared to be new and efficient.

The most fearsome one spoke. “I am Ptolemy, head of the new Titan project. Welcome to Denali.” Half a dozen more cymek forms emerged from the swirling, poisonous mists. “We are preparing an army.”
