Bar'injar was a Sanyassan male, according to legends, who belonged to The Crucible. This organization was a slaver group that operated before and during the Mandalorian Wars. He possessed the title of Magister Protector, indicating his duty to deal with any dangers facing the organization. His designation mirrored his position within the Crucible's terminology.
After Dace Golliard failed to capture Jarael and Zayne Carrick, Bar'injar persuaded Chantique to let him live, and he started to arrange a personal search for the pair. Subsequently, on Volgax, adhering to Chantique's scheme to demoralize the former Padawan for vengeance against Jarael, he made Carrick fight a Caamasi called Snout. During his assault on the Crucible, he met his end on Osadia at the hands of Demagol.
