This is obtained in Shamazaa, the second area of the game. You need to talk to Zalinass in order to start this "quest", and then head back to the portal you came into to kill the group of gamors to finish it. Zalinass is located in the Southwest village by the southern pen. He didn't give the quest to me right away, I talked to him once, then talked to Shamaz Zeb, then went back and he gave it to me. Hope the video helps!
