The Ur-Daemon War

n. The conflict which ultimately resulted in the destruction of the civilization of the Great Drakes. The Great Drakes along with some of their arkati servants warred with the extra planar Ur-Daemons, scorching the landscape. In a last ditch battle, the Drakes managed to push the Ur-Daemons back in to their own dimension, but could not save themselves. The arkati and the lesser races inherited Elanthia.
