Dave and Nema were hustled into the cave, while the others melted into the woods, studying the skies. She clung to Dave, crying something about how the Sons of the Egg would torture them.

"All right," he said finally. "Who are these sons of eggs? And what have they got against me?"

"They're monsters," she told him. "They used to be the antimagic individualists. They wanted magic used only when other means wouldn't work. They fought against the Satheri. While magic produced their food and made a better world for them, they hated it because they couldn't do it for themselves. And a few renegade priests like my brother joined them."

"Your brother?"

"She means me," Bork said. He came in to drop on his haunches and grin at Dave. There was no sign of personal hatred in his look. "I used to be a stooge for Sather Karf, before I got sick of it. How do you feel, Dave Hanson?"

Dave considered it, still in wonder at the truth. "I feel good. Even the venom they were putting in my blood doesn't seem to hurt any more."

"Fine. Means the Sather Karf must believe we killed you—he must have the report by now. If he thinks you're dead, there's no point in his giving chase; he knows I wouldn't let them kill Nema, even if she is a little fool. Anyhow, he's not really such a bad old guy, Dave—not, like some of those Satheri. Well, you figure how you'd like it if you were just a simple man and some priest magicked her away from you—and then sent her back with enough magic of her own to be a witch and make life hell for you because she'd been kicked out by the priest, but he hadn't pulled the wanting spell off her. Or anything else you wanted and couldn't keep against magic. Sure, they fed us. They had to, after they took away our fields and the kine, and got everyone into the habit of taking their dole instead of earning our living in the old way. They made slaves of us. Any man who lets another be responsible for him is a slave. It's a fine world for the Satheri, if they can keep the egg from breaking."

"What's all this egg nonsense?"

Bork shrugged. "Plain good sense. Why should there be a sky shell around the planet? Look, there's a legend here. You should know it, since for all I know it has some meaning for you. Long ago—or away, or whatever—there was a world called Tharé and another called Erath. Two worlds, separate and distinct, on their own branching time paths. They must have been that way since the moment of creation. One was a world of rule and law. One plus one might not always equal two, but it had to equal something. There seems to be some similarity to your world in that, doesn't there? The other was—well, you'd call it chaos, though it had some laws, if they could be predicted. One plus one there depended—or maybe there was no such thing as unity. Mass-energy wasn't conserved. It was deserved. It was a world of anarchy, from your point of view. It must have been a terrible place to live, I guess."

He hesitated somberly. "As terrible as this one is getting to be," he said at last. "Anyway, there were people who lived there. There were the two inhabited worlds in their own time lines, or probability orbits, or whatever. You know, I suppose, how worlds of probability would separate and diverge as time goes on? Of course. Well, these two worlds coalesced."
