From the introduction:
A Glabrezu named Kh'teesh was brought to this failing temple of Anubis by a power-hungry acolyte named Babel. Recognizing the potential for exploitation, Kh'teesh created the religion of "the Eternal," fabricating a palatable history that would prey on the greed of mortals. The acolyte Babel was elevated to the vaunted position of High Priest, and has met with remarkable success spreading his "word".
