Mysterium Xarxes
From the OblivioWiki – your guide to everything Oblivion
This book is supposedly written by Mehrunes Dagon. It is the focus of the four book set, Commentaries on the Mysterium Xarxes by Mankar Camoran. It is a thick, gray tome that has the letter "Oht" from the Daedric alphabet in the cover of the book.
The Mysterium Xarxes is both the gate and the key to Camoran's Paradise. In a way it is Camoran's Paradise. Mankar Camoran bound himself to the Xarxes and the book enables Martin to open a portal. The book also holds various magical incantations and rituals, which can be used to open a portal to Paradise. However, this portal requires four artifacts to draw its power upon: a Great Welkynd Stone, a Great Sigil Stone, a Daedric artifact, and the Blood of a Divine. When all four objects are laid together, the envokation that the Mysterium Xarxes holds binds the four objects togther, which results in the creation of a giant sphere of orange light and fire. This is the portal to Paradise. Once the Mysterium Xarxes is stolen from the Mythic Dawn cult at the Dagon Shrine and given to Martin Septim, the main character is unable to carry the book again.
