Crusaders of Dahzbog

A mysterious group of paladins and clerics from another world. They worship the sun god Dahzbog and are on an eternal crusade to rid the world of the influence of "Czernobog" the "eldest evil, black god of deception and darkness." They visited Arlyss in 1773 AD seeking one of the black scripts of Czernobog. They mentioned the "Grand Admiralty of Kiev" before departing.
