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 began when he found a drug that would keep his Zkauba-facet always dormant, yet without dissolution of the knowledge and memories of Zkauba. He thought that his calculations would let him perform a voyage with a light-wave envelope such as no being of Yaddith had ever performed--a _bodily_ voyage through nameless eons and across incredible galactic reaches to the solar system and the Earth itself. Once on Earth, though in the body of a clawed, snouted thing, he might be able somehow to find--and finish deciphering--the strangely hieroglyphed parchment he had left in the car at Arkham; and with its aid--and the key's--resume his normal terrestrial semblance. He was not blind to the perils of the attempt. He knew that when he had brought the planet-angle to the right eon (a thing impossible to do while hurtling through space), Yaddith would be a dead world dominated by triumphant Dholes, and that his escape in the light-wave envelope would be a matter of grave doubt. Likewise was he aware of how he must achieve suspended animation, in the manner of an adept, to endure the eon-long flight through fathomless abysses. He knew, too, that--assuming his voyage succeeded--he must immunize himself to the bacterial and other earthly conditions hostile to a body from Yaddith. Furthermore, he must provide a way of feigning human shape on Earth until he might recover and decipher the parchment and resume that shape in truth. Otherwise he would probably be discovered and destroyed by the people in horror as a thing that should not be. And there must be some gold--luckily obtainable on Yaddith--to tide him over that period of quest.
