Borun Call was an infamous Quarren slaver active since the days of the Old Republic. He was responsible for introducing Slar-dan ti Gardi to the slave trade. When Gardi was briefly captured by Tauran Nartal, Call rescued his former partner and captured Nartal in the process. Call also aided the Galactic Empire in enslaving the Talz of Alzoc III. Call owned a Sydon Vehicle Works MRX-BR Pacifier called the Vanquisher, which served as the flagship of his slaving fleet.
