The book consists primarily of a novelized walkthrough for each game, in the form of journal entries purportedly written by the Avatar himself during his adventures in Britannia. These journals are presented in the context of two Britannian historians who, during the time of the Guardian's rise to power (just prior to the opening of Ultima VII), are researching the stories of the Avatar and debating their authenticity. Maps, item and enemy lists, and simplified, "quick and dirty" walkthroughs are also provided. The Avatar's story would be continued in "More Avatar Adventures".
