War of the Burning Sky
An order of druids calling themselves the Wardens believe that all the other organized religions have got it wrong. Life was created by all four elements coming together, therefore it is the duty of living beings to keep these elements in check, both internally and externally. When the balance of nature is upset, the Wardens take action. Thus, their enemies are those who actively promote one of the elements. In particular, they dislike the Order of the Cleansing Flame for its one-sided doctrine.
