It’s a world in which seven great continents hang in the sky, stacked almost vertically far above an unending sparkling sea. And shining down upon it all is a limitless light, emanating not from a great sun or moon, but from the sky itself: the hallowed Overlight. 

The heroes of this world are called the Skyborn. These individuals are born to disparate folk and cultures the world over, and who on some deep genetic or spiritual level are driven to make the world a better place, knowing in their hearts that things are not as they should be. The Skyborn are able to consciously manipulate the Overlight, fracturing it into seven distinct colors and using it to power remarkable abilities called Chroma.
