Unbeknownst to the creatures who were contentedly living on the surface, there was actually a hidden sixth empire of the great Land of Lirea. This hidden empire lies exactly beneath the Middle Land, the land of the faeries. And it was called the Under Land, the land of the real dark Faes.
The Under Land was a paradise in the dark and the dark faes were all living there together in peace as one united people. The dark faes were the real creatures of the dark. They were born of the dark, they embraced the dark and they thrive in the dark. They cannot live long on the surface because the light has some elements that limited them, not only in their growth, but even more so, in their magic.
