The Cosmic Era of Millettarian Mystology is the one-hundred and thirty-second and final instalment in the Little Blue Book Series and comprises the sixteenth and final discourse of the Dodecadoxy and by extension, the last discourse of the entire Omnidoxy. The Cosmic Era of Millettarian Mystology introduces audiences to an important segment of Astronic mythology, namely mystology which incorporates explicit Astronist and cosmontological beliefs and ideas into the story of how the effigy of Jesse achieved cosmosis.
 
The Little Blue Book Series was created and first published by Cometan himself as a way to simplify and commercialise the immensity of the two million word length of the Omnidoxy into smaller, more bite-size publications. A successful series from its very first published entry, the Little Blue Book Series has gone on to become a symbol of Astronist commercial literature and a way for Cometan’s words to reach readers of all ages and abilities who remain daunted by the beauty and yet the sheer extensiveness of the Omnidoxy as the longest religious text in history.
