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 of some kind." "Just my point. Not _humanly_ possible. I think these ruling class Disans aren't human at all, like the other Disans. I think they are alien creatures--robots or androids--anything except men. I think they are living in disguise among the normal human dwellers." At first Lea started to smile, then her feeling changed when she saw his face. "You are serious?" she asked. "Never more so. I realize it must sound as if I've had my brains bounced around too much this morning. Yet this is the only idea I can come up with that fits all of the facts. Look at the evidence yourself. One simple thing stands out clearly, and must be considered first if any theory is to hold up. That is the magters' complete indifference to death--their own or anyone else's. Is that normal to mankind?" "No--but I can find a couple of explanations that I would rather explore first, before dragging in an alien life form. There may have been a mutation or an inherited disease that has deformed or warped their minds." "Wouldn't that be sort of self-eliminating?" Brion asked. "Anti-survival? People who die before puberty would find it a little difficult to pass on a mutation to their children. But let's not beat this one point to death--it's the totality of these people that I find so hard to accept. Any one thing might be explained away, but not the collection of them. What about their complete lack of emotion? Or their manner of dress and their secrecy in general? The ordinary Disan wears a cloth kilt, while the magter cover themselves as completely as possible. They stay in their black towers and never go out except in groups. Their dead are always removed so they can't be examined. In every way they act like a race apart--and I think they are." "Granted for the moment that this outlandish idea might be true, how did they get here? And why doesn't anyone know about it besides them?" "Easily enough explained," Brion insisted. "There are no written records on this planet. After the Breakdown, when the handful of survivors were just trying to exist here, the aliens could have landed and moved in. Any interference could have been wiped out. Once the population began to grow, the invaders found they could keep control by staying separate, so their alien difference wouldn't be noticed."
