Holy magic can be only loosely defined as such. It is the power of the limitless gods of light and paradisiacal heavens that the many races of men have called their own throughout history. Only the most devout of holy persons may utilize this celestial strength. Any transgression against the gods will strip Clerics of their power. Note that Holy magic stems only from the worship of so-called benevolent deities, such as the One God and His Host.
