Back Story
Just like humans or tribal societies in general, barbarians are citizens of a nation that some or even many consider less civilized or less organized but can also be members of cultural groups of certain "primitive" social classes.
Barbarians are considered a group of people or society who are savage, cruel, do not know the proper rules of life, always act as they wish, and are heartless. However, to a few groups, barbarians are called virtuous savages because their presence becomes a bridge to destroy the existence of supernatural beings whose abilities and existence threaten ordinary humans who live around them.
In short, the barbarians are often referred to and known as a group of bandits who like to make noise and chaos wherever they live and settle.
Meanwhile, Hunters are generally a society whose primary method of survival is hunting or gathering directly edible wild animals and plants.
