Pantheon of Avaleen

The Titans were born of the spirit of Avaleen, and destroyed by Beings not of the World.

Their purpose is to protect mortals and their interests. Devoted souls are like batteries for them, heightening their power by actions that directly relate to the god/goddess' domain. Even if these actions are intentional acts of devotion or not. Which is how the Fallen still has influence.

The Pantheon is a reference to all the deities that have in some way influenced the course of Avaleen's culture and history.

The Primary Deities are the leaders and luminary creators that battled the Primordial Titans for control of the young world of Avaleen. Through their power they created the mortal races and calmed the elements by banishing them to their own planes. They hold sway over powers that represent a spectrum of the natural world, the passage of time, life and death and other facets of freedom and existence in the world. While these gods may squabble and disagree amongst themselves, they are united in their dedication to the survival of what is ultimately their creations.

The Fallen Deities are those who strayed from the ideals and vision of the Core and embraced the destructive chaos of the Primordial Titans.
