Jarad Gastin, who was a male Sullustan officer, served the Rebel Alliance during the period of the Galactic Civil War. Following the Battle of Yavin, Lieutenant Gastin found himself stationed on the desert planet of Tatooine, where he based his operations out of a tavern located in the settlement of Anchorhead. Within this well-known Rebel base, he took in credit donations from those sympathetic to the Rebel cause, who were eager to bolster their war efforts. During the year 1 ABY, Jarad Gastin was the recipient of a substantial contribution, totaling one million credits, from a spacer whose identity remained a mystery.
Jarad Gastin existed as a non-player character within the 2003 video game Star Wars Galaxies, a massively multiplayer online role-playing game. The game was created by Sony Online Entertainment and distributed by LucasArts, before it was shut down on December 15, 2011. The character of Major Lt. Jarad Gastin was introduced to the game through the implementation of Game Update 9, which took place on April 30, 2009. He was among the three NPCs (along with Major Caleb Knolar and Ozzmos Roberts) added with the update, who functioned as credit sinks designed to extract currency from the game's economy and mitigate the effects of inflation. By contributing a sum of one million credits, players were awarded the title "Rebel Sympathizer."
