Vayonism
Vayonism, also known as Vayonistic Hexadecism and known chiefly among its adherents as the Faith of the Sixteen, is a continuum of religious denominations with a common origin in the writings of the religious scholar and philosopher Vayon of Aratheda, reconciling the Ancient Elyrian religion with various contemporary philosophical teachings. The term Vayonism is an exonym coined by non-adherants during the religion's early ascendency; practicioners tend to employ the old label of Faith of the Sixteen already in use before the Vayonistic reform.
Commonalities between the majority of self-declared Vayonistic denominations include a monistic theology, the belief in sixteen aspects of the Divine Being modeled after the gods of the Ancient Elyrian pantheon, and a dualistic cosmology focused on the complementary, interconnected, and interdependent forces of order and chaos.
