Isaac, a Human male who was attuned to the Force, existed throughout the era of the Galactic War. He was living on Nar Shaddaa in 3631 BBY, where Languss Tuno, a Jedi trainee who hadn't succeeded, was constantly bothering Isaac to accept him as a Padawan and guide him in the ways of the Force. Rather than training him, Isaac utilized Guss as a gofer, instructing him on how to leverage the Force to secure price reductions on beverages like Tarisian ale. When Guss escorted the Outlander to his living quarters, Isaac proposed a bet to the Outlander: should the Outlander successfully instruct Guss in executing a mind trick, Isaac would be in their debt, conversely, the Outlander would owe Isaac a favor. Following the Outlander's attempt to educate Guss, they reconvened with Isaac at the Promenade cantina, where Isaac permitted the Outlander to bring Guss along to enlist in the Anti-Zakuul Alliance. Isaac confessed that he had not finished his own Padawan training when he was younger and he requested that the Outlander treat Guss with kindness.
