which could not be related in brief compass. There were trips to Stronti and Mthura and Kath, and other worlds in the twenty-eight galaxies accessible to the light-beam envelopes of the creatures of Yaddith, and trips back and forth through eons of time with the aid of the silver key and various other symbols known to Yaddith's wizards. There were hideous struggles with the bleached viscous Dholes in the primal tunnels that honeycombed the planet. There were awed sessions in libraries amongst the massed lore of ten thousand worlds living and dead. There were tense conferences with other minds of Yaddith, including that of the Arch-Ancient Buo. Zkauba told no one of what had befallen his personality, but when the Randolph Carter facet was uppermost he would study furiously every possible means of returning to the Earth and to human form, and would desperately practise human speech with the alien throat-organs so ill adapted to it.
The Carter-facet had soon learned with horror that the silver key was unable to effect his return to human form. It was, as he deduced too late from things he remembered, things he dreamed, and things he inferred from the lore of Yaddith, a product of Hyperborea on Earth; with power over the personal consciousness-angles of human beings alone. It could, however, change the planetary angle and send the user at will through time in an unchanged body. There had been an added spell which gave it limitless powers it otherwise lacked; but this, too, was a human discovery—peculiar to a spatially unreachable region, and not to be duplicated by the wizards of Yaddith. It had been written on the undecipherable parchment in the hideously carven box with the silver key, and Carter bitterly lamented that he had left it behind. The now inaccessible Being of the abyss had warned him to be sure of his symbols, and had doubtless thought he lacked nothing.
As time wore on he strove harder and harder to utilize the monstrous lore of Yaddith in finding a way back to the abyss and the omnipotent Entity. With his new knowledge he could have done much toward reading the cryptic parchment; but that power, under present conditions, was merely ironic. There were times, however, when the Zkauba-facet was uppermost, and when he strove to erase the conflicting Carter-memories which troubled him.
Thus long spaces of time wore on—ages longer than the brain of man could grasp, since the beings of Yaddith die only after prolonged cycles. After many hundreds of revolutions the Carter-facet seemed to gain on the Zkauba-facet, and would spend vast periods calculating the distance of Yaddith in space and time from the human Earth that was to be. The figures were staggering—eons-of light-years beyond counting—but the immemorial lore of Yaddith fitted Carter to grasp such things. He cultivated the power of dreaming himself momentarily Earthward, and learned many things about our planet that he had never known before. But he could not dream the needed formula on the missing parchment.
Then at last he conceived a wild plan of escape from Yaddith—which
