As a matter of plain fact, however, Kinnison's first and most positive conclusion was wrong. His memories were factual records of actual events and things. He would eat well during his stay upon that nameless planet, but he would have to procure his own food. Nothing would attack him, or even annoy him. For the Eddorian's _binding_--this is perhaps as good a word for it as any, since "geas" implies a curse--was such that the Gray Lensman could return to space and time only under such conditions and to such an environment as would not do him any iota of physical harm. He must continue alive and in good health for at least fifty more of his years. * * * * * And Clarrissa Kinnison, tense and strained, waited in her room for the instant of her husband's death. They two were one, with a oneness no other man and woman had ever known. If one died, from any cause whatever, the other would feel it. She waited. Five minutes--ten--fifteen--half an hour--an hour. She began to relax. Her fists unclenched, her shallow breathing grew deeper. Two hours. Kim was _still alive_! A wave of happy, buoyant relief swept through her; her eyes flashed and sparkled. If they hadn't been able to kill him in two hours, they never could. Her Kim had plenty of jets. Even the top minds of Boskonia could not kill her Kim! XXVIII. The Arisians and the Children of the Lens had known that Eddore must be attacked as soon as possible after the fall of Ploor. They were fairly certain that the interspatial use of planets as projectiles was new; but they were completely certain that the Eddorians would be able to deduce in a short time the principles and the concepts, the fundamental equations, and the essential operators involved in the process. They would find nth space or one like it in one day; certainly not more than two. Their slaves would duplicate the weapon in approximately three weeks. Shortly thereafter both Ultra Prime and Prime Base, both Klovia and Tellus, would be blown out of the ether. So would Arisia--perhaps Arisia would go first. The Eddorians would probably not be able to aim such planets as accurately as the Arisians had, but they would keep on trying and they would learn fast. This weapon was the sheer ultimate in destructiveness. No defense against it was possible. There was no theory which applied to it or which could be stretched to cover it. Even the Arisian Masters of Mathematics had not as yet been able to invent symbologies and techniques to handle the quantities and magnitudes involved when those interloping masses of foreign matter struck normal space.
