The Lemurian Empire was one of the first ruling governments of Earth's ancient past, once governed nearly all of Asia and Oceania. An unknown catastrophic event occured that nearly wiped out the entire Lemurian civilization and their empire. Forced to take refuge beneath the surface and given a reasonable amount of unclaimed territories from the Hollow Earth Kingdom. Their empire slowly recovered but kept themselves hidden from their Human cousins as they have become the most populated species on the planet and made themselves isolated from the Surface, including the Djinn. Like all other races that inhabit the same planet, they could find any clue of what happened 4,000 years ago.
