[@Dinh AaronMk]I had an old faction of nomads from an old NRP which I never got to play so they might fit quite well here.
They would be remnants of a once thriving nation and they prefer using matchlock handgonnes on horseback and preserved the associated technology through primitive means. Shamans would be the cornerstones of their culture who are polyhistors serving as religious leaders, record keepers, wise men/scientists, healers and most other roles associated with these. Of course not many shamans are literally skilled in everything but if you need any of these, you were looking for a shaman. It is their intellectual group in society. As for vague misticism or fantasy would it be okay if I use a different brew of materials for my gunpowder equivalent which is worse yet can be gathered from various plants and materials found within forests.
