Moss Shelby, a resident of Corellia and a member of the Corellian Security Force, held the rank of officer during the era of the Galactic Civil War. Following the Battle of Yavin, he attained the position of lieutenant within CorSec's Regiment Twelve. In 1 ABY, when sizable beasts from the Agrilat Swamp began encroaching upon populated regions of Corellia, prompting concerns among local agriculturalists, they sought Shelby's assistance. Unwilling to expend CorSec's assets on this matter, the lieutenant instead engaged a team of spacers to handle the situation.
The character Moss Shelby was referenced within the video game Star Wars Galaxies: An Empire Divided, a massively multiplayer online role-playing game that launched in 2003. This game was developed by Sony Online Entertainment, published by LucasArts, and ultimately shut down on December 15, 2011. Shelby's name appeared in the mission "Large Creatures on the Move," which could be accessed via mission terminals located on Corellia.
