[@Cu Chulainn], at this time I am intent on making the question of deities a matter for consideration. As with older editions, deities and forces have more power based on their believers, so in essence, there is a personified form of these concepts. Going beyond this there, as with what we saw with the Pact of Undying Light warlock, there truly exists the pure essence of good.

What does this in particular mean? Your deities do exist in the cosmology of the Planes, but they are only minor players as mere mortals would be to them. I do not plan on any interaction with them, for reasons I cannot mention at this time, but there is nothing stopping you from devising your own philosophy.

As such, feel free to be creative in doing so, but remember all that I ask is it is a force of unquestionable good; not Pelor type conspiracy. Divine magic, more than anything, is faith and belief in those powers; good in the case of players. You might have that connection through strong ritual and practice, as a cleric might as that is how they were taught or practice, or more with a Favored Soul because that spark of good is so strong that you can call upon a personal, deep connection.

The overarching "good guys" and "bad guys" fall onto those spectrum. 

Yes, the nebulous darkness does so as well, but as I realize those few pursuers of dark desires are few in number. Powerful, sure, but the minions of darkness are more numerous than individually mighty.
