The Hutt crime lord Riboga initiated a spice-mining venture known as the Spice Mines of Kemix. This operation was based on the planet Kemix and began during the Clone Wars following Riboga's discovery of naturally occurring glitterstim deposits. Ultimately, the Heroes of Cularin—a group of independent operatives originating from the Cularin system—obliterated the mine, significantly weakening Riboga's criminal organization.
