Unit Idea:
How about placing some dwarf mercenries in the mountanous areas. Give them strong moral, and a strong defense. Make them fight to the last man kinda thing like spartans. Not sure how they would look exept they would be small and have big beards and carry hammers or axes. They would have quite stong armour but be rather slow. This is how i picture them anyway. I think they would be a cool addition to the mod.
