Biography
3D's part in the operation was to escort Senator Orn Free Taa with a pardon disc to the Republic Judiciary Central Detention Center in an airspeeder with a transport for the Hutt behind it. When Ziro was released and boarded the transport, 3D piloted it back to the Senate Building, where the rest of the team, including Cad Bane, Aurra Sing, Shahan Alama and Robonino boarded the craft and sucessfully left the crime scene.
