As time wore on he strove harder and harder to utilise 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 hundred 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 — aeons 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 aeons 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 aeon (a thing impossible to do while hurtling through space), Yaddith would be a dead world dominated by triumphant bholes, 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 aeon-long flight through fathomless abysses. He knew, too, that — assuming his voyage succeeded — he must immunise 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.
Slowly Carter’s plans went forward. He provided a light-wave envelope of abnormal toughness, able to stand both the prodigious time-transition and the unexampled flight through space. He tested all his calculations, and sent forth his earthward dreams again and again, bringing them as close as possible to 1928. He practiced suspended animation with marvellous success. He discovered just the bacterial agent he needed, and worked out the varying gravity-stress to which he must become used. He artfully fashioned a waxen mask and loose costume enabling him to pass among men as a human being of a sort, and devised a doubly potent spell with which to hold back the bholes at the moment of his starting from the black, dead Yaddith of the inconceivable future. He took care, too, to assemble a large supply of the drugs — unobtainable on earth — which would keep his Zkauba-facet in abeyance till he might shed the Yaddith body, nor did he neglect a small store of gold for earthly use.
The starting-day was a time of doubt and apprehension. Carter climbed up to his envelope-platform, on the pretext of sailing for the triple star Nython, and crawled into the sheath of shining metal. He had just room to perform the ritual of the Silver Key, and as he did so he slowly started the levitation of his envelope. There was an appalling seething and darkening of the day, and a hideous racking of pain. The cosmos seemed to reel irresponsibly, and the other constellations danced in a black sky.
All at once Carter felt a new equilibrium. The cold of interstellar gulfs gnawed at the outside of his envelope, and he could see that he floated free in space — the metal building from which he had started having decayed ages before. Below him the ground was festering with gigantic bholes; and even as he looked, one reared up several hundred feet and levelled a bleached, viscous end at him. But his spells were effective, and in another moment he was falling away from Yaddith unharmed.

In that bizarre room in New Orleans, from which the old black servant had instinctively fled, the odd voice of Swami Chandraputra grew hoarser still.
