Brion followed the technician out to the car and helped him load his equipment aboard. When the larger cars appeared out of the darkness, Telt swung around after them. They snaked forward in a single line through the rocks, until they came to the desert of rolling sand dunes. Then they spread out in line abreast and rushed towards their goal. Telt hummed to himself hoarsely as he drove. He broke off suddenly and looked at Brion. "What you want the dead Dis for?" "A theory," Brion answered sluggishly. He had been half napping in the chair, taking the opportunity for some rest before the attack. "I'm still looking for a way to avert the end." "You and Hys," Telt said with satisfaction. "Couple of idealists. Trying to stop a war you didn't start. They never would listen to Hys. He told them in the beginning exactly what would happen, and he was right. They always thought his ideas were crooked, like him. Growing up alone in the hill camp, with his back too twisted and too old to be fixed when he finally did come out. Ideas twisted the same way. Made himself an authority on war. Hah! War on Nyjord. That's like being an icecube specialist in hell. But he knew all about it, but they never would let him use what he knew. Put granddaddy Krafft in charge instead." "But Hys is in charge of an army now?" "All volunteers, too few of them and too little money. Too little and too damned late to do any good. I'll never be good enough. And for this we get called butchers." There was a catch in Telt's voice now, an undercurrent of emotion he couldn't suppress. "At home they think we like to kill. Think we're insane. They can't understand we're doing the only thing that has to be done--" He broke off as he quickly locked on the brakes and killed the engine. The line of sandcars had come to a stop. Ahead, just visible over the dunes, was the summit of a dark tower. "We walk from here," Telt said, standing and stretching. "We can take our time because the other boys go in first, soften things up. Then you and I head for the sub-cellar for a radiation check and find you a handsome corpse." Walking at first, then crawling when the dunes no longer shielded them, they crept up on the Disan keep. Dark figures moved ahead of them, stopping only when they reached the crumbling black walls. They didn't use the ascending ramp, but made their way up the sheer outside face of the ramparts. "Linethrowers," Telt whispered. "Anchor themselves when the missile hits, have some kind of quicksetting goo. Then we go up the filament with a line-climbing motor. Hys invented them." "Is that the way you and I are going in?" Brion asked. "No, we get out of the climbing. I told you we hit this rock once before. I know the layout inside." He was moving while he talked, carefully pacing the distance around the base of the tower. "Should be right about here."
