The Herdessan Guild was the leading faction on the planet Herdessa during the Galactic Civil War. The guild was responsible for the profitable trade that made the planet very rich. However, the guild only distributed the wealth to a small portion of the populace, resulting in a large social class gap between the rich and the poor. Following the Battle of Endor, the guild allied themselves with Lumiya to create a slave trade on Herdessa, selling members of the lower class to other worlds.
