In the year 1 ABY, a gunrunner, a male Human, assisted the Chubbit resistance against the Galactic Empire. This assistance involved smuggling weapons to the reptilians of the Chubbit homeworld, Aridus. This gunrunner had ties to the Alliance to Restore the Republic. When Imperial stormtroopers disrupted a weapons transaction, the Human escaped with his Chubbit allies. During his escape, he thought he saw the deceased Jedi Master Obi-Wan Kenobi, who was, in actuality, an actor employed by Darth Vader. The gunrunner then departed Aridus, going back to Yavin 4, the moon which served as the Alliance's base of operations at that time. Once there, he told Luke Skywalker about what he witnessed, which led Skywalker to journey to Aridus to encounter who he believed was his old Master, thus setting off Vader's scheme.
