Originally from the planet Gentes in the remote Anoat system , Ugnaughts were taken away from their homeworld as slaves long before the Imperial era . Entire tribes would often be sold into slavery . The remaining Ugnaughts lived on the planet ' s less - than - hospitable surface . When the Corellian eccentric and noble Lord Ecclessis Figg wished to build a floating mining complex on Bespin , he decided to recruit several Ugnaught tribes to help in the mining of the base metals needed to build the structure . He bought the services of three Ugnaught tribes : the Botrut , the Isced , and the Irden . He promised them freedom , livelihood and a share in the Figg & Associates profits .
