From the pictures I turned to the bulky, closely-written letter itself; and for the next three hours was immersed in a gulf of unutterable horror. Where Akeley had given only outlines before, he now entered into minute details; presenting long transcripts of words overheard in the woods at night, long accounts of monstrous pinkish forms spied in thickets at twilight on the hills, and a terrible cosmic narrative derived from the application of profound and varied scholarship to the endless bygone discourses of the mad self-styled spy who had killed himself. I found myself faced by names and terms that I had heard elsewhere in the most hideous of connections—Yuggoth, Great Cthulhu, Tsathoggua, YogSothoth, R'lyeh, Nyarlathotep, Azathoth, Hastur, Yian, Leng, the Lake of Hali, Bethmoora, the Yellow Sign, L'mur-Kathulos, Bran, and the Magnum Innominandum—and was drawn back through nameless aeons and inconceivable dimensions to worlds of elder, outer entity at which the crazed author of the Necronomicon had only guessed in the vaguest way. I was told of the pits of primal life, and of the streams that had trickled down therefrom; and finally, of the tiny rivulets from one of those streams which had become entangled with the destinies of our own earth.
