In creating a fantasy setting, I decided that all magical power has a cost. For mortals, of course this comes through a number of channels - the gods, demons, elemental lords, or hard work for lesser (compared to other disciplines) power. But for other worldly powers, the power comes directly from souls. The demons get their souls from corrupting humanity into damnation. The Elemental Lords (who are more primordial and might be the creators of the universe) proffer elemental magic in return for eternal servitude in wars against other lords. The gods are other entities who have gathered into pantheons (with false origin stories) to share souls from worshipers. And while many gods were angels prior to hatching this private pool theory, I have no idea what the role of angels are in this cosmology.
Does anyone have any ideas how I could solve this conundrum? Because I really want angels to be movers and shakers (as both allies and antagonists), but feel that I've pushed them out of any tangible role in this cosmology.
