The young acolyte Thoth-amon rises quickly through the priestly ranks of Ibis as one by one his fellows fall victim to grisly deaths by an unseen hand. Bewildered and powerless to halt the carnage, one priest fears he has discovered the source of the evil encroaching upon the city, only to learn that the truth is far more horrifying than anyone could have imagined. Meanwhile, the citizens of Memphia are losing faith in the ability of Ibis to protect them, and rumors are spreading of a far more powerful and ancient deity—the snake-god Set. This essential piece of the Conan mythos uncovering the origin of his greatest villain is co-written by Len Wein, creator of Swamp Thing and Wolverine, and Kurt Busiek, Eisner award-winning writer of the best-selling Conan ongoing series, and drawn by Kelley Jones, much-proclaimed master of horror!
