The Catalog of Intelligent Life in the Galaxy, was written by Imperial sentientologist Obo Rin as a reference for other sentientologists and Imperial personnel. It described several prominent sentient species of the galaxy, and was written under the patronage of Darth Vader and Lieutenant Pandur, the Imperial Liaison Officer to Korfo II. Unfortunately, the work was rife with Imperial propaganda, and thus not completely reliable; for instance, longstanding non-Human members of the Galactic Republic such as the Mon Calamari and Columi were said in the work to have only recently been discovered by the Empire.
