G0-T0
this ancient, spherical protocol droid was discovered on Nar Shaddaa, several years after the Jedi Civil War. It had originally been dispatched to the planet Telos by the Old Republic, in the wake of the Mandalorian Wars and the Jedi Civil War, to ensure that Telos was able to rebuilt itself and become part of the Republic's rennaissance. However, G0-T0 could not reconcile its primary object with its programming to abide by the laws of the Republic, and its computer brain snapped. G0-T0 turned rogue, and established itself as the leader of a smuggling ring that was based on Nar Shaddaa. In this way, it was able to acquire what it needed to rebuild Telos, but it also learned that there were more credits in smuggling. Adopting the mysterious alias of Goto - since most beings would not take orders from a droid - G0-T0 rose to prominence on Nar Shaddaa, and eventually assumed control of The Exchange. In order to hide its true identity, G0-T0 managed its operations from a starship that was cloaked as it drifted in orbit around Nar Shaddaa. In order to fool The Exile, who had discovered its ship, G0-T0 presented itself to the former Jedi as a "gift" from Goto. G0-T0's true identity was revealed in the wake of the destruction of Malchor V, an event that G0-T0 tried to prevent.
