The Life of Muad'Dib, Volume 2 was the second publication printed by Princess Irulan Corrino, the wife of Emperor Paul Atreides, after the Ascension of House Atreides to the throne of the Imperium. Volume 2 had to be published by the Emperor's wife, as certain discrepancies existed in the birthplace and childhood of Paul.
In the first publication, Life of Muad'Dib, 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. The Life of Muad'Dib, once published, was considered holy and religious reading for many of the loyal Fremen Jihadis who followed Paul after his takeover of the Golden Lion throne.
But 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 first publication, and questioned her husband. Paul calmly explained that the first particular version of his life was streamlined, and that the first 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 decided to write the expanded version of Paul's life, including all of the events of his childhood, hence the entitles, The Life of Muad'Dib, Volume 2. The Princess included that at 12 years of age he had been involved in the Ecazi/Moritani struggle, and had left Caladan to see that fight finished on Grumman.
After meeting with Lady and Duchess Jessica Atreides to learn more about Paul's younger life, and to perform the will of the Regent Alia Atreides in furthering the mythos about Paul's reign as Emperor, Iruland decided to write The Life of Muad'Dib, Volume 3.
