Outcast - Second Contact

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!

After spending some time in Shamazaar, you'll come across a character called Zalinass, located near the village with the healer, who will ask you for help in protecting Twon-ha from gamors (gamors kind of look like small tiger/hyena creatures). If you make your way back to the portal (Daoka) when you first arrived in Shamazaar, the gamors will have spawned around there. They are aggressive so you'll know what they are, take them out and the achievement will pop, no need to hand it in. I don't think you need to speak to Zalinass to activate the side quest as the gamors had already spawned on the map for me.
