Malaclypse the Younger (short Mal-2) was a pen name used by Gregory Hill in writing the Principia Discordia. He was also adapted as a character in The Illuminatus! Trilogy. Hill was a comrade of Kerry Wendell Thornley (aka Lord Omar Khayyam Ravenhurst). During the early years of circulation of the Principia Discordia, rumors claimed that the author of the book was Richard Nixon, Timothy Leary, or Robert Anton Wilson; or that the book and Malaclypse the Younger were both fictional inventions of Robert Anton Wilson, e la H. P. Lovecraft's Necronomicon
