Divinity in Saleh'Alire
Believing that the beginning of time was far too long ago for anyone to truly know the reality of what happened, Alirans care very little about debating the hows, whys, and whens of Divine existence. They instead choose to look to the reality of the present... And the undeniable reality of the present is that several Deities do in fact exist across a multitude of cultures, times, and places. More, they are powerful and tangible beings who walk freely among the various Planes of existence. This is, in large part, due to their supreme interconnectedness with The Weave itself.
The nature of the Divine is not one which is static and unchanging, however. It instead exists in a constant state of flux, with new beings ascending to Divinity and old ones falling or dying off entirely. This is because nothing is divorced from the natural cycle of Life and Death- and in the Aliran worldview, this includes the beings they call Deities; even those who have ascended to divine status are still viewed as mortal creatures- albeit incredibly long lived mortals whose power, and mere state of existence, is far beyond the comprehension of those who haven't achieved a similar level of power in their own right.
Few Tolarans care what it is or how it came to be- let alone why. But all planar denizens agree The Weave is an invisible energetic force that surrounds and permeates everything. Anyone with an inclination to do so can, with enough time, study, and and effort, learn to manipulate it for spellcasting. Some who study it may even master it, becoming experts in one school of magic or another. But those who truly master every element of it may learn how to become a part of The Weave itself. Deities are therefore, in common thought, individuals who have mastered, and become one with, The Weave- unlocking a level of power which normal people will only ever dream of possessing.
My dearest and most beloved friend, we are about to do something both incredibly foolish, and immensely dangerous... But by the dusk and dawn, Corellon himself has put us on the same path- and I am convinced it was for a purpose. I only hope there is enough time in our lives to complete this God given task.— Egmes Aceyr, in a letter to Ytlena e'Ovohric
