"That's right. The way I picture it, lots of nations grew up, all racing each other, as well as the ice, to get the technological edge. Every other one was a rival, so they fought it out. Another thing that made them fight was the mineral shortage, especially the shortage of metallic ores." Maddson pointed at a map of Minerva mounted above the table. "See those dots on the ice sheets? Most of them were a combination of fortress and mining town. They dug right down through the ice to get at the deposits, and the army was there to make sure they kept the stuff."

"And that was the way life was. Mean people, eh?"

"Yeah, for generation after generation." Maddson shrugged. "Who knows? Maybe if we were freezing over fast, we'd be forced in the same direction. Anyhow, the situation had complications. They had the problem of having to divide their efforts and resources between two different demands all the time: first, developing a technology that would support mass interplanetary travel and, second, armaments and the defense organization to protect it—and there weren't a lot of resources to divide in the first place. Now, how would you solve a problem like that?"

Hunt pondered for a while.

"Cooperate?" he tried.

"Forget it. They didn't think that way."

"Only one other strategy possible, then: Wipe out the opposition first and then concentrate everything on the main objective."

Maddson nodded solidly. "That is exactly what they did. War, or near war, was pretty well a natural way of life all through their history. Gradually the smaller fish were eliminated until, by the time we get to Charlie, there are only two superpowers left, each dominating one of the two big equatorial continental land masses . . ." He pointed at the map again. ". . . Cerios and Lambia. From various references, we know Charlie was a Cerian."

"All set for the big showdown, then."

"Check. The whole planet was one big fortress-factory. Every inch of surface was covered by hostile missiles; the sky was full of orbiting bombs that could be dropped anywhere. We get the impression that relative to the pattern of our own civilization, their armaments programs had taken a bigger share than space research and had progressed faster." Maddson shrugged again. "The rest you can guess."

Hunt nodded slowly and thoughtfully. "It all fits," he mused. "It must have been a huge con, though. I mean, even from whichever side won, only a handful would have been able to get away in the end; I suppose they'd have been the ruling clique and its minions. Christ! No wonder they needed good propaganda; they—"

Hunt stopped in midsentence and looked at Maddson with a curious expression. "Just a minute—there's something else in all this that doesn't add up." He paused to collect his thoughts. "They had already developed interplanetary travel—how else did they get to our Moon?"
