Uburluh, a physician and physicist within the Brotherhood of the Sith, possessed expertise in prosthetics and was a male doctor. Following the Ambush in the Ansharii Caverns, where Haazen was attacked by Dossa, the severely injured, unsuccessful Padawan was taken to Uburluh for medical attention. Uburluh promptly began the process of saving Haazen's life, aware that Haazen would be significantly scarred after the procedure. Upon regaining consciousness and seeing his reflection, Haazen cried out in anguish to Uburluh, demanding, "What have you done to me?!"
Dossa informed him that he had been healed and further enhanced with numerous Sith artifacts to amplify his power, including the Yoke of Seeming. Uburluh clarified that this device would allow the Living Force to bypass him, thereby obscuring his true motives from others. Dossa proposed that Haazen could achieve invincibility by acquiring even more Sith relics. However, Haazen, having heard enough, retaliated against Dossa for her actions by ending her life.
