Tinketh Fo, sometimes called "Boss," was an astute male Pinurquian who served as the planetary leader of Keyorin during the Galactic Civil War. In the aftermath of the Galactic Empire's climactic defeat at Endor in 4 ABY, Han Solo, Chewbacca, and Lando Calrissian—emissaries from the newly formed Alliance of Free Planets—visited Keyorin and asked Fo to attend the upcoming First Conference of Free Peoples, and represent Keyorin's interests. Although Fo was initially skeptical, he was impressed by Solo's panache and promised to consider the idea. the Pinurquian ultimately attended the conference in Endor, listening to speeches from Alliance leader Mon Mothma and Admiral Gial Ackbar.
