Walking further up the road, towards Bthardamz I come across the remaining Orc Hunter, he is just standing in the road, a dead comrade is a few feet away from him. Some imperial soldiers are walking past when he suddenly attacks them, and is killed. Then I see a Stormcloak archer coming running over the hill and now there's a mini-war on.
This road is FUN!
Really wonder what the story about the "captive" is though. Can't recall seeing any forswarn captives before. And why naked and empty.
Druadach Redoubt is close by, this is where Madanach is and his crew are friendly and knows me, so I guess they must come from there. But it's still a pretty long walk.
Edit: I walked back, the Forsworn seemed gone for a moment, but they weren't. Walking between the two groups the dog suddenly bit me and my follower killed him.

Edit 2: Now this is interesing! I headed to Druadach Redoubt and their population seemed far thinner than usual. Only one forsworn there who wasn't one of the named ones that moved there after a certain mission. Furthermore I noticed the cage for the first time and the door was open. Could this be one of those small mini-stories you got to work out yourself? If so, great job, Beth!
Edit 3: Assuming that my earlier conclusion was correct I decided to re-create her escape route. Right around the corner (following the tiny dirt road) I find a dead Bandid Marauder next to a free horse.
