The long War Rising
The Northern Tribes is an amalgation of pastoralist tribes in the northern regions. Loosely organized and generally few in number, the northern tribes are viewed as an oddity in the modern world. Though they are independant of the Imperial government they are still considered Impereial citizens by the Empire for the purpose of travel and trade. The mostly herd large groups of carabou, and trade in carabou and caribou accessories.
What makes the Northern Tribes perhaps the most distinct from other ethnic groups is their perscribance to a druidic religion that does not acknowledge the Great Saint Ashihara as a true holy figure, but only a historic one. Instead they believe in having a strong connection with nature and the fey. The Druids of the northern tribes travel quite far south compared to their brethern, and in fact these druids are usually the sole interaction that most people will ever have with people of the northern tribes.
