Eian

Eian are the majestic bird-dragon creatures that inhabit the Plains of Gaoth. They were the native semi-sentient race that lived there before the Changed came about. They are now the primary method of transportation between the continents and worlds of the Plains, and are more populous then the Changed themselves. An Eian forms a bond with a specific person, and will answer to that person only for the rest of either's life, similar to the Mountain Banshees of James Cameron's Avatar.
