Where is the Kae'Ran Champion? >.<. I'm stuck!

[MarinusMaximus]

So, i got all camps and now i have to do the Betrayal mission, but where do i go?
There is NO icon to tell me were the next location is. I have run around the map twice and found nothing.
Please help!!!

Edit: I finnaly found it, but the quest is bugged. He just stands there and i cannot attack him, nor do i get attacked by enemies

As the name suggests, he's in the Kae'Ran tribe camp.
