Written by the imp Kyriyes, the Black Journal chronicles the affairs of the Black Tide, its leaders, and detailed accounts of the people and locations encountered. The text spans the period from the launch of the Black Tide of Thasmudan in 1464 to their dark legions passing into Sorrow Pass in 1479 - a fifteen-year period documented extensively, with each scroll placed in a portable archive. An unseen servant acting as a librarian then encrypted these scrolls, adding them to a magical archive of nearly fifty volumes.
The Black Journal is an uncommon literary work, with a portion furnishing data for Asmodeus's intelligence network, and the remainder satiating Asmodeus's recollections of his esteemed Covenant days on Bal-Kriav, in the same territories that Kyriyes had traversed as an underling of the Black Tide.
