The Qun is a hyper-controlling philosophy that won't even give its people actual names. They also believe it's their destiny or their duty to convert the rest of the world. To say they're extremists is to put it lightly, and they often spread the word by the sword, so to speak. They consider non-Qunari to be even less than human -- the actual word is bas, meaning "thing" -- and anyone who leaves the Qun needs to be killed on sight. They don't make allies, and certainly not without prices that shouldn't be paid.
