The Qun is not just a religion, but a way of life. It is based off of the philosophies of the philosopher, Ashkaari Koslun. Those who are Qunari -- "people of the Qun" -- follow it. This is not just limited to the horned Kossith race, though they are the ones who brought the Qun to Thedas. For more information on the Qun, see Qunari.
