|“||Whether created specifically for use in the service of Torm or appropriated at some point in the long history of the church, Paladins of the Loyal Fury have made good use of Daystar in their battles against evil undead. Through magic or blessing it is empowered with the Sunray, a force of pure life energy so potent that it slays both living and unliving.||”|
