The book played a critical role in the fictional series Illuminatus! by Robert Anton Wilson and Robert Shea regarding a coup in Fernando Poo (now Equatorial Guinea), which was the outward trigger for a global crisis in the book.
The style and setting of the game draw on a number of influences, including the fantasy novels of Tim Powers, the crime novels of James Ellroy, the films of David Lynch, the Illuminatus! Trilogy, and comic books such as Grant Morrison's The Invisibles.
