Etheria, the Lost Kingdom in Encantadia

Etheria is a a kingdom that had vanished right before the reign of the diwatas in Lireo. It is a kingdom which planned to destroy the other creatures of Encantadia such as the diwatas, making the Kabilan for themselves. It is the reason for the war of all the kingdoms against Etheria. A round door with the sun designed on the center, serves as a passage to another dimension world. The reason why it existed is what this series is all about.
