Then one very ancient zoog recalled a thing unheard of by the others; and said that in Ulthar, beyond the river Skai, there still lingered the last copy of those inconceivably old Pnakotic Manuscripts made by waking men in forgotten boreal kingdoms and borne into the land of dreams when the hairy cannibal Gnopkehs overcame many-templed Olathoe and slew all the heroes of the land of Lomar. Those manuscripts, he said, told much of the gods; and besides, in Ulthar there were men who had seen the signs of the gods, and even one old priest who had scaled a great mountain to behold them dancing by moonlight. He had failed, though his companion had succeeded and perished namelessly.
