The Varlians were the ancestors of the Hutts. A race of giant insectoid who ruled a large star empire named the Varlian Empire. The Varlians had on their side Rodians and Gamorreans to control the slaves composed of Humans, Biths, Ithorians, Kubaz, Ortolans, Kitonaks, Twi'leks, Mon Calamari and Sullustans. The species began evolving into the Hutt species when Gelleda, son of Delba, had failed to develop his cocooning apparatus, pushing the larvae to continue growing without passing into the adult stage of their life cycle. The Varlians thought that this mutation was due to the Changa Bloodrot, a plague which nearly wiped out the Varlians centuries ago (a disaster which they believed to be divine retribution for failing to enslave the primitive Wookiees).
