Divinity.
This one, mysterious energy that could be felt in every temple dedicated to a God. This energy was a general term for the power wielded directly by the Gods. It was a generally accepted term, even though the forms of Divinity differed between the Gods in the same way these divine beings differed from each other.
In a more understandable manner, the same way Holy and Unholy energy existed and coexisted with one another, that was also the same in the case of Divinity. There was a higher form of Holy energy, which was the Divinity of some Gods, while there was a higher form of Unholy energy that acted as the Divinity of other Gods. The knowledge of these types of energies were however lost on the mortals of the world, as no God would divulge such information to mortals.
