Background
Like the other Elemental Princes, Yan-C-Bin has few human followers on Oerth, due to the popularity of the cults of Elemental Evil and the Elder Elemental God. Most of his followers are evil elementals, elemental spirits, and creates of air, including a large number of evil-inclined cloud giants. His human priesthood is reasonably organized (if not powerful), though largely confined to small towns and rural areas. Most are found in the Great Kingdom of Aerdy [Ahlissa in post-wars campaigns]. Yan-C-Bin seeks to displace the many air powers of Oerth (including the four wind spirits of the Oeridians), most likely a hopeless task in light of his powers.
