Gon-Sa, a male of the Voss species, worked as a diplomat. He was present during a conference where Republic Senator Evran and Sith Lord Torius attempted to persuade the Voss to align with them for safety. Nevertheless, the Voss did not require protection, as their mystics foresaw all dangers; for example, Mystic Ki-Ve divined Torius's scheme to detonate a ZR-57 orbital strike bomb in Voss-Ka. Since the Voss were aware that Havoc Squad Major would thwart Torius, they remained passive observers until the Sith was eliminated. Following the Sith's death, the Voss disclosed their knowledge and requested that the Republic provide them with the bomb for analysis.
