Divine Power originates from the Material Plane, the Positive & Negative Planes, the Ethereal & Shadow Planes; Divine Power flows from these coterminous Planes to all other planes; it is extremely difficult to make Divine Power flow back to the Material Plane; Deities that gain too much Divine Power are repelled by the Material Plane.
Divine Power comes in multiple forms: Orderly, Ethically Neutral, Chaotic, Unholy, Morally Neutral, Holy.
Orderly Divine Power is very strongly antagonistic towards Chaotic Divine Power and vice-versa.
Unholy Divine Power is fairly antagonistic towards Holy Divine Power and vice-versa.
Ethical Neutrality is Divine Power that is either fairly balanced between the forces of Order & Chaos or antagonistic towards either extreme.
Moral Neutrality is Divine Power that is either fairly balanced between the forces of Holy & Unholy or antagonistic towards either extreme.
