Brejik was the leader of the Black Vulkars, a swoop gang of the Lower City on Taris that, under his direction, led a gang war against their rivals the Hidden Beks in the time of the Jedi Civil War. Formerly the lieutenant to Gadon Thek, head of the Hidden Beks, Brejik defected to the Black Vulkars when his mentor refused to retire and allow him to succeed. The war he prosecuted as head of the Black Vulkars wrecked chaos throughout the Lower City. When he captured and enslaved the Jedi Knight Bastila Shan, he provoked the intervention of two agents of the Republic, Revan and Carth Onasi, ultimately leading to his downfall.
