For the caravan/camp idea, the guardians that protect it could have taken it up as a mission to protect it to a certain point and get a reward from it, like in Mount&Blade. If you haven't played the series then you're missing out, although I don't blame you if you've heard of it but don't like it. Everyone has their own cup of tea. (I think thats how the saying goes right? Well idk, and idc)
