Always just an NPC character, Shaolo created a big reputation after her was able to work the Sith and Jedi battle for Manaan into his and his people's favor, eventually beating back the Sith, due to his madness and the madness of his people caused by the progenitor. He was rumored to receive a green ring, that the Selkath believe to be magical and the cause for their great victory that day.
After the battle, Shaolo was captured by the Imperials but eventually was freed in a deal with Agent Purple Rain for the safety of his world and ended up betraying the Jedi and Rebels to give the world to the Empire and the Sith. In the battle though he was killed for his treatchery by Rebel Agent Hawk Solo. His statue and ring remain yet on the now Imperial world of Manaan.
