Jake Harthan, who hailed from the Tion Hegemony, was a Human male (male) and the offspring of Counselor Harthan.
Around the time of 5.5 BBY, when they found themselves dispatched to Tahlboor, he learned about the existence of the sky cannon. Driven by a desire to control it, he orchestrated a scheme by instigating a deadly conflict between the Troobs and Hobors. This involved the assassination of Ket Krax, for which he falsely accused Larka Nimondro. Nevertheless, C-3PO intervened and disrupted his scheme just as the two groups were about to engage in full-scale warfare. Despite his subsequent efforts to harness the power residing within Mount Yeroc, a Troob brought about his demise by impaling him with a spear.
