"Dis," Ihjel said, consulting a thick file, "third planet out from its primary, Epsilon Eridani. The fourth planet is Nyjord—remember that, because it is going to be very important. Dis is a place you need a good reason to visit and no reason at all to leave. Too hot, too dry; the temperature in the temperate zones rarely drops below a hundred Fahrenheit. The planet is nothing but scorched rock and burning sand. Most of the water is underground and normally inaccessible. The surface water is all in the form of briny, chemically saturated swamps—undrinkable without extensive processing. All the facts and figures are here in the folder and you can study them later. Right now I want you just to get the idea that this planet is as loathsome and inhospitable as they come. So are the people. This is a solido of a Disan."
Lea gasped at the three-dimensional representation on the screen. Not at the physical aspects of the man; as a biologist trained in the specialty of alien life she had seen a lot stranger sights. It was the man's pose, the expression on his face—tensed to leap, his lips drawn back to show all of this teeth.
"He looks as if he wanted to kill the photographer," she said.
"He almost did—just after the picture was taken. Like all Disans, he has an overwhelming hatred and loathing of offworlders. Not without good reason, though. His planet was settled completely by chance during the Breakdown. I'm not sure of the details, but the overall picture is clear, since the story of their desertion forms the basis of all the myths and animistic religions on Dis.
"Apparently there were large-scale mining operations carried on there once; the world is rich enough in minerals and mining them is very simple. But water came only from expensive extraction processes and I imagine most of the food came from offworld. Which was good enough until the settlement was forgotten, the way a lot of other planets were during the Breakdown. All the records were destroyed in the fighting, and the ore carriers were pressed into military service. Dis was on its own. What happened to the people there is a tribute to the adaptation possibilities of homo sapiens. Individuals died, usually in enormous pain, but the race lived. Changed a good deal, but still human. As the water and food ran out and the extraction machinery broke down, they must have made heroic efforts to survive. They couldn't do it mechanically, but by the time the last machine collapsed, enough people were adjusted to the environment to keep the race going.
"Their descendants are still there, completely adapted to the environment. Their body temperatures are around a hundred and thirty degrees. They have specialized tissue in the gluteal area for storing water. These are minor changes, compared to the major ones they have done in fitting themselves for this planet. I don't know the exact details, but the reports are very enthusiastic about symbiotic relationships. They assure us that this is the first time homo sapiens has been an active part of either commensalism or inquilinism other than in the role of host."
"Wonderful!" Lea exclaimed.
"Is it?" Ihjel scowled. "Perhaps from the abstract scientific point of view. If you can keep notes perhaps you might write a book about it some time. But I'm not interested. I'm sure all these morphological changes and disgusting intimacies will fascinate you, Dr. Morees. But while you are counting blood types and admiring your thermometers, I hope you will be able to devote a little time to a study of the Disans' obnoxious personalities. We must either find out what makes these people tick—or we are going to have to stand by and watch the whole lot blown up!"
"Going to do what!" Lea gasped. "Destroy them? Wipe out this fascinating genetic pool? Why?
