GaRaLa is the mirror world to LaRaGa. It has the same gods, and much of the same magic and level of technology, but the peoples and other creatures that inhabit it are different, as is the lay of the land.
While LaRaGa has the magic clans to spread the Elemental Gods' power, GaRaLa has the Elementalists - strange people through whom the gods' magic flows, often at random.
GaRaLa also has many more types of people than LaRaGa. As well as having nearly every race of LaRaGa, GaRaLa has shapeshifters, Reinmara, and many others. Unlike LaRaGa though, GaRaLa has no Nature or Chaos Powers.
