Tribe

Tribals refers to the name given to rural inhabitants by those still livng in urban areas. They have shucked off many modern ways of living, and returned to a simpler hunter-gatherer mentality. Despite the fact that tribals are generally healthier and in better physical condition than their urban-dwelling countrymen, they are viewed with disdain and often hostility. It is not unknown for tribals to be captured and put to work as slaves. This unfortunate fact goes some way towards explaining the animosity between urban dwellers and tribals.
