Bianlu, to outsiders "the five sided way", is the official religion of the Eyaw Empire. It arose out of the elemenal worship of the Aarakocra after they entered the material plane and came into contact with the The Fourteen.
Hong the Devourer. Hong is a creature from Aaracokra folklore. It is unknown whether it actually exist or not. The Fourteen are rather confused and slightly miffed about it's inclusion in the Bianlu pantheon. The current theory is that it was added so that every element had 3 gods.
