Book (The Legend of... the Master?)
From Tardis Wiki, the free Doctor Who reference
In his TARDIS, the War Master had a book containing the legend of his escape from his world. The book also contained drawings of the individuals, species, and locations the Master had travelled to, including Time Lords, Skaro, Chantho, an Ogron, a Sea Devil, an Ood, a Dalek, and Gallifrey, as well illustrations of him and his TARDIS.
