Zythanism

Zythanism, also known as the Draconic Faith, is the state religion of the Dominion of New Haven, and revolves around two main concepts; the first being the reverence of the Dragonqueen Zythia and her brood of Arcane Dragons, the second being the in-depth study of magic and the universe.
Though Zythia is the primary being worshiped by the followers of Zythanism, she is not considered a god, rather something more like a demigod or a prophet. She is certainly seen as a paragon of wisdom and intelligence, but not an omnipotent, omniscient deity. As such, Zythanists would not pray to Zythia, they are far too rational for that, instead they simply listen to and obey her teachings, which are passed down through her brood and her priests.
The Arcane Dragons as a whole are seen as mentors and protectors of humanity. They have intervened many times throughout history to protect Haven and New Haven from disaster, so evidence of their strength is demonstrable, not simply a matter of faith. Their mentorship is however more nebulous. It is believed that it was dragonkind who first taught humanity how to speak the language of the universe in order to cast magic, and Zythanists will say that they have continued to guide humanity to discover more about the natural laws of the universe and the way magic interacts with it.
There are 13 foundational texts which form the ideological basis for Zythanism, called the 13 Zythan Papers. These were written over several points in history, and are structured like well-researched academic texts, outlining the principles of Zythanist beliefs about the world. Each one goes into a different subject, but they are connected by the theme of magic being the fundamental energy of the universe, and the Arcane Dragons being the purest form of that energy given life. Some of these papers were written by dragons, dictating through human interpreters, but most were written by human archmages and priests.
