Dooku's personal record was a datapad encased in aged leather, detailing Dooku's history within the Jedi Order and tracing his advancement until he left the organization. Within its pages were accounts of his training under Grand Master Yoda, expeditions to places like Mantooine, Lahsbane, and Kashyyyk, diplomatic meetings, rescue operations, acts of compassion, and a period when Dooku and his mentor freed a star system from the necrotic queen. Initially stored on Serenno, it was later entrusted to Asajj Ventress. The assassin examined the journal's entries during her mission to find and rescue Dooku's abducted sister, Jenza, seeking insight into Dooku's character.
Following Jenza's death, the journal was destroyed by fire, with Dooku instructing that his sister's demise be concealed; Ventress saturated the area with flammable gas, ignited it, and cast the journal into the inferno.
