In the publication, Irulan presented what came to be known as a streamlined version of the life of Emperor Paul Atreides prior to his and including his victory over Shaddam Corrino IV on Arrakis. Irulan wrote, and this version was published in the year 10193 AG The Life of Muad'Dib was considered holy and religious reading for many of the loyal Fremen Jihadis who followed Paul after his takeover of the Golden Lion throne.
Later, after Irulan questioned the some of Paul's childhood accomplices, such as Swordmaster Whitmore Bludd, about Paul's involvement in the War of Assassins of 10,187 AG, Irulan had doubts about the publication, and questioned her husband. Paul calmly explained that this particular version of his life was streamlined, and that this version of his biography was made for mass consumption.
After Irulan questioned all of Paul's childhood friends and accomplices about Paul's early years, Irulan renamed this version of Paul's life, The Life of Muad'Dib, Volume 1. The Princess found out that Paul had been born on Kaitain, not Caladan; that at 12 years of age he had been involved in the Ecazi/Moritani struggle; and that he had run away to join a traveling Jongleur face dancer group.
To reconcile such differences, further details about Paul's birthplace and youth were fleshed out in Irulan's The Life of Muad'Dib, Volume 2.
