"he is described as a "tall, swarthy man" who resembles an ancient Egyptian pharaoh. In this story he wanders the earth, seemingly gathering legions of followers, the narrator of the story among them, through his demonstrations of strange and seemingly magical instruments.

The story ends with the narrator as part of an army of servants for Nyarlathotep."
