The Codex of All Mysteries was the magnum opus of Dorius Alyre ir'Korran, a thick tome detailing the most intriguing things he discovered during his life. The Codex contains information on all of the planes of Eberron, the mysterious Sphinx's, and all manner of other mysteries. Whilst the Codex originally contained information on some of the Overlord's, Dorius would later move this information into a new work, the Manual Maleficent.
