The Journal of Darth Malgus was a war journal kept by Darth Malgus during the Great Galactic War and was acquired by Palpatine decades before the rise of his Galactic Empire through an antiquities dealer. Palpatine passed it to his Sith apprentice, Darth Vader, in the hopes it would inspire him. Vader found many similarities between himself and Malgus, and annotated the remains of the journal heavily, expressing regret that no more of it survived.
