Gods in the Dawn of Time
Gods in the Dawn of Time are all custom developed concepts. While we are not ruling out the use of Forgotten Realms Gods, they will likely all be considered false Gods in the Dawn of Time. There are a number of false Gods in the Dawn of Time, this is due to the inherent nature of people.
The real definition of a God in this world is a mortal that has transcended from the Plane of Death to one of the other Metaphysical Planes as described in the DoT Planar Physics Model. The ability to transcend involves a persons ability at leadership and the tenacity of their followers. Humans and Dwarves who are good leaders may be able to transcend but that does not always mean that every leader will turn into a God. Only the really special leaders do. Once the transition is fully complete, Gods can send blessings down to the Material Plane using Divine Intervention Magic.
Therefore, Gods are the source of all Divine Magic used by the Cleric in the Material Plane. The Cleric cannot cast spells without their Gods as the Cleric is just a servant and a follower of said God.
To the evles, all Gods are false Gods and the elves see themselves as protectors of the balance of life in the material plane. The elves will even bring balance to the Gods if they must. The Gods are not all powerful, they do not control all of the Plane of existance that they live in, not even close.
