Who are the Earthen?

The Titans empowered a number of races to help them fashion the world. To help them carve out the fathomless caverns beneath the earth, the Titans created the dwarf-like earthen from magical, living stone. To help them dredge out the seas and lift the land from the sea floor, the Titans created the immense but gentle sea giants. For many ages the Titans moved and shaped the earth, until at last there remained one perfect continent.
