Hanson nodded. He'd have to shield the cord from the sun stuff, but that could be done. He wondered idly whether the real universe was going to wind up with tracks beyond the sky on which little duplicate planets ran--just how much similarity would there be between model and reality when this was done, if it worked at all? It probably didn't matter, and it could hardly be worse than whatever the risers had run into beyond the hole in the present sky. Metaphysics was a subject with which he wasn't yet fully prepared to cope. The model of the world inside the orrery must have been made from earthly materials already, and it was colored to depict land and sea areas. It could probably be used. At their agreement, he nodded with some satisfaction. That should save some time, at least. He stared doubtfully at the rods and bearings that supported the model world in the center of the orrery. "What about those things? How do we hold the globe in the center of everything?" Bork shrugged. "It seems simple enough. We'll fashion supports of more of the sky material." "And have real rods sticking up from the poles in the real universe?" Hanson asked sarcastically. "Why not?" Bork seemed surprised at Hanson's tone. "There have always been such columns connecting the world and the sky. What else would keep us from falling?" Hanson swore. He might have guessed it! The only wonder was that simple rods were used instead of elephants and turtles. And the doubly-damned fools had let Menes drive millions of slaves to death to build a pyramid to the sky when there were already natural columns that could have been used! "There remains only one step," Sather Karf decided after a moment more. "To make symbol and thing congruent, all must be invoked with the true and secret name of the universe." Hanson suddenly remembered legends of the tetragrammaton and the tales of magic he'd read in which there was always one element lacking. "And I suppose nobody knows that or dares to use it?" There was hurt pride of the aged face and the ring of vast authority in his voice. "Then you suppose wrong, Dave Hanson! Since this world first came out of Duality, a Sather Karf has known that mystery! Make your device and I shall not fail in the invocation!" For the first time, Hanson discovered that the warlocks could work when they had to, however much they disliked it. And at their own specialties, they were superb technicians. Under the orders of Sather Karf, the camp sprang into frenzied but orderly activity.
