One thing I forgot to mention. Hrestolism is still alive even in areas dominated by the Rokari. Periodically people get glimpses of the Joy of Hrestoli and celebrate his Joy in confused ceremonies where people cry tears of joy, fall to their knees and pray to the Creator for allowing them just that glimpse of what awaits them. Plagues of frenzied (but very joyful) madmen wash through the rural lands until they are crushed by the soldiers of the noble house responsible for that area.
