She swung back to the microscope, centering the specimen with a turn of the stage adjustment screw. "Poor Ihjel was right when he said this planet was exobiologically fascinating. This is a gastropod, a lot like Odostomia, but it has parasitical morphological changes so profound—"
"There's something else I remember," Brion said, interrupting her enthusiastic lecture, only half of which he could understand. "Didn't Ihjel also hope that you would give some study to the natives as well as their environment. The problem is with the Disans—not the local wild life."
"But I am studying them," Lea insisted. "The Disans have attained an incredibly advanced form of commensalism. Their lives are so intimately connected and integrated with the other life forms that they must be studied in relation to their environment. I doubt if they show as many external physical changes as little eating-foot Odostomia on the slide here, but there will be surely a number of psychological changes and adjustments that will crop up. One of these might be the explanation of their urge for planetary suicide."
"That may be true—but I don't think so," Brion said. "I went on a little expedition this morning and found something that has more immediate relevancy."
For the first time Lea became aware of his slightly battered condition. Her drug-grooved mind could only follow a single idea at a time and had overlooked the significance of the bandage and dirt.
"I've been visiting," Brion said, forestalling the question on her lips. "The magter are the ones who are responsible for causing the trouble, and I had to see them up close before I could make any decision. It wasn't a very pleasant thing, but I found out what I wanted to know. They are different in every way from the normal Disans. I've compared them. I've talked to Ulv—the native who saved us in the desert—and I can understand him. He is not like us in many ways—he would certainly have to be, living in this oven—but he is still undeniably human. He gave us drinking water when we needed it, then brought help. The magter, the upper-class lords of Dis, are the direct opposite. As cold-blooded and ruthless a bunch of murderers as you can possibly imagine. They tried to kill me when they met me, without reason. Their clothes, habits, dwellings, manners—everything about them differs from that of the normal Disan. More important, the magter are as coldly efficient and inhuman as a reptile. They have no emotions, no love, no hate, anger, fear—nothing. Each of them is a chilling bundle of thought processes and reactions, with all the emotions removed."
"Aren't you exaggerating?" Lea asked. "After all, you can't be sure. It might just be part of their training not to reveal any emotional state. Everyone must experience emotional states whether they like it or not."
"That's my main point. Everyone does—except the magter. I can't go into all the details now, so you'll just have to take my word for it. Even at the point of death they have no fear or hatred. It may sound impossible, but it is true."
Lea tried to shake the knots from her drug-hazed mind. "I'm dull today," she said, "you'll have to excuse me. If these rulers had no emotional responses, that might explain their present suicidal position. But an explanation like this raises more new problems than it supplies answers to the old ones. How did they get this way? It doesn't seem humanly possible to be without emotions."
