About the series:
In the time before time, when the domains of earth, sea, and sky were formed and fire was called into being, the elementals took shape, each with their element: the children of earth, the children of the sea, the children of air, and the children of fire. After earth had flowered and life crawled from the sea, humankind was born.
The children of fire rebelled against this new creation, declaring war on the children of the air and humankind. Forced to cohabit with the mortals, the other elementals withdrew–the fair folk to the hills and wild places of earth and the merfolk, selkie and finfolk, to the depths of the sea.
