Jul Tambor's forces comprised the assembled adherents and associates of a nationalist group led by the Skakoan Jul Tambor. This organization initiated an uprising with the goal of retaking the planet Skako Minor from the control of the Galactic Empire. To further his aims, Tambor also recruited pirates to establish a blockade around Skako Minor. Although Tambor asserted that the pirates responsible for the attacks on Brentaal IV were not connected to his activities, his inherent self-serving nature meant his statements were not consistently truthful.
