Jonset, a Zabrak male, resided on Corellia during the era of the Galactic Civil War. In the period following the Battle of Yavin, he frequented a cantina in Coronet City, acting as an informant for the Corellian Security Force. In the year 1 ABY, Lieutenant Mack Jasper of CorSec dispatched a spacer to inquire with Jonset regarding the Rogue CorSec. Jonset furnished details concerning a clandestine meeting between the Rogue CorSec and the Ragtag gang. The CorSec's subsequent investigations into the Rogue CorSec and Ragtag connection unveiled a scheme to overthrow the Diktat, specifically Daclif Gallamby himself.
Within the 2003 video game Star Wars Galaxies, Jonset was featured as a non-player character. This massively multiplayer online roleplaying game was created by Sony Online Entertainment and distributed by LucasArts, prior to its shutdown on December 15, 2011.
Jonset's inclusion in the game occurred with the release of "Publish 25," also known as the "New Game Enhancements," on November 15, 2005. He played a role in a questline centered around the Rogue CorSec's plot against the Diktat. This narrative was later slightly revised with the arrival of "Publish 27", on February 15, 2006, as the questline was incorporated into the "Legacy Quest," which served as the game's primary questline.
