"But--Lord, man! Why've we never heard anything about this? You mean you never told anyone, never rebuilt any of those machines, never did anything?" Laird's dark, worn face twisted in a bleak smile. "Certainly. This civilization isn't ready for such things. Even Vwyrdda wasn't, and it'll take us millions of years to reach their stage. Besides, it was part of the bargain." "Bargain?" "Just as certainly. Daryesh and I still had to live together, you know. Life under suspicion of mutual trickery, never trusting your own brain, would have been intolerable. We reached an agreement during that long voyage back to Sol, and used Vwyrddan methods of autohypnosis to assure that it could not be broken." He looked somberly out at the lunar night. "That's why I said the genie in the bottle killed me. Inevitably, the two personalities merged, became one. And that one was, of course, mostly Daryesh, with overtones of Laird. "Oh, it isn't so horrible. We retain the memories of our separate existences, and the continuity which is the most basic attribute of the ego. In fact, Laird's life was so limited, so blind to all the possibilities and wonder of the universe, that I don't regret him very often. Once in a while I still get nostalgic moments and have to talk to a human. But I always pick one who won't know whether or not to believe me, and won't be able to do much of anything about it if he should." "And why did you go into Survey?" I asked, very softly. "I want to get a good look at the universe before the change. Daryesh wants to orient himself, gather enough data for a sound basis of decision. When we--I--switch over to the new immortal body, there'll be work to do, a galaxy to remake in a newer and better pattern by Vwyrddan standards! It'll take millennia, but we've got all time before us. Or I do--what do I mean, anyway?" He ran a hand through his gray-streaked hair. "But Laird's part of the bargain was that there should be as nearly normal a human life as possible until this body gets inconveniently old. So--" He shrugged. "So that's how it worked out." We sat for a while longer, saying little, and then he got up. "Excuse me," he said. "There's my wife. Thanks for the talk." I saw him walk over to greet a tall, handsome red-haired woman. His voice drifted back: "Hello, Joana--" They walked out of the room together in perfectly ordinary and human fashion. I wonder what history has in store for us.
