Background
Grii Zelieegga ("Grii") used to work as a personal advisor to Senator Onaconda Farr, the senator of Rodia in the Galactic Republic's Senate. Her role as Senator often lead to Aargau, where she was bombarded with lavish luxury and pleasures, all to gain access to Senator Farr. She became very wealthy trading money for access. Several transactions later, she realized she was working for Jabba Desilijic Tiure ("Jabba the Hutt"). Upon discovering this fact, she remained quiet as she did not want to give up her position. The Senator discovered Grii's treachery and exiled Grii. Senator Farr was furious but so was Grii. Knowing about a very large shipment to Rodia, Grii told Jabba who saw an opportunity. Jabba raided the shipment using pirates. The rest is history.
