A little more on my character: traveler, maybe a tinkerer or jack of all trades. Probably trades or peddles as they go, more of a scavenger,definitely not a raider. I can see them having a vague interest in all the settlements being unified under a single banner, even more so if there is some benefit to them. Particularly if there is a chance to make new contacts or connections in the places being built. I doubt they have any formal combat or military training, instead having a cobbled together fighting style using whatever they find hat suits them. It will not be as efficient or as strong as someone with proper training so they will likely let more on weapons or dirtier moves.
