I this video I reach the rebel camp and talk to the leader and then inform the captain of the outpost.
From my starting point at the top of the hill I could see 3 natives, I tried to sneak past but I was noticed, these are the last natives you’ll have to fight unless you don’t side with the natives.
Over the next hill and down in the valley is the rebel camp. When you talk with her you’ll have to the option to attack them, I did not.
All that’s left is to return to the outpost and inform Reihild the outpost captain of your conversations with the rebels. The side quest is worth 1400 xp.
Thanks for watching and happy gaming
