I have all the info on the Gorax, both SWG Stats and Ewok Adventures.. remember watching that as a kid. Anyway..
According to what I have read and remember from watching, Gorax has a cave in a tall mounting near or past a Desert.
In SWG.. we was a Spawned Mission Target, that you got from one of the Marauders. But the mission was changed, and he was supposedly removed from the game, then added back. I have seen where people tell of a Cave where Minor gorax live and The Gorax is sort of the "Boss" or King MOB there. Also heard accounts of him being a wondering MOB. But either way no one has been able to provide a Waypoint.
I have researched the Endor Map and tried to a list of POI's together that would in someway link the two sources together. And I have found several pretty tall mountains near and past the Desert on Endor. I have also found Ewok markers.. no spawns just static things.. like a pole in the ground with Ewok tribal stuff hanging from it surounded by a ring of small animal skulls. Seeing that the Ewoks hate and fear the Gorax I figured this could be either a warning marker, or just eyecandy from the devs.
I know I may be looking to deep into this but what the hell.. nothing else to do, till they can add more content.
