Drentak was a once a leader of a group of mercenaries called Wraiths that would take on any job that came there way. He slowly gathered more people, taking on riskier and riskier jobs in order to increase the groups fame, this led to quick success until they took on a job that left the group completely shattered. They thought it was a regular 'get rid of this person' type gig however in turned out to be more than they could handle, the request came in to get rid of a Cathar woman taking over racketeering operations on a small desert world, the client being a the last large organised criminal group left on the planet. The job started out easy enough they tracked the Cathar to a underground fighting pit where people would bet on fights between the criminals, captives and beasts. Drentak and his team made their way in blending in with the crowd in order to fight her, however when the next fight was meant to start Drentak lost contact with his team members one by one and then suddenly he felt a dull thud in the back of his neck as he was sent flying off the stands into the pit, he was disoriented and force himself to his feet. The cathar looked at him surprised, she seem shocked that he survived whatever she had done to him, after gathering his sense he looked around and saw his comrades bodies being thrown down from the crowd into the pit, the Cathar woman leapt down with them and drew what Drentak recognised to be a lighter saber. The blade ignited lighting up the arena in a red light, Drentak not unconfident in his duelling skills viewed this as his last chance to complete the job, he took up his weapon and swung it down upon the Cathar, to his shock however her blade went through his like it was nothing cutting his blade in half and piercing into his chest. The surprise and sudden immense pain left Drentak barely conscious as he fell to the floor, the last thing he saw a two men jump down into the pit with their own green and blue lightsabres lit.
Ever since this Drentak's group never recovered as not only did most of the skilled members die that day their reputation plummeted as they failed to complete a job, as sudden as the rise was their fall was faster. This left huge impacted on Drentak's mind, he became obsessed with Sith, Jedi and the force as he craved the strength that defeated him, he wished to harness it himself or figure out how to overcome it so he would never be humiliated like that again. This lead him to seek out republic missions as they were the force opposing the Sith.
