[@Dinh AaronMk]I'd interact with the rest of the world, of course. I just like the idea of fallen nations that almost forgot their roots yet they have a few vestiges. It is certain my people would have no monopoly over guns, neither did they contribute to their further development much. I just like the idea they have guns for a messed up reason that they turned into a religious element. Of course they would trade with the neighbors and likely adopt lessons others have learned in gunmaking. I neither mean them to be isolated from the rest, nor I think primitive gun wielding nomads are superior to the classic horse archers. It's just different which gives me interesting potential for roleplaying.
