Long ago people had built up a great civilization under the guidance of the goddesses the Trio of Elemia, but over the years things have changed; there were two disasters that have lead towards the destruction of the world. In the first disaster most of the lands and skies were lost, in the second the super civilization was lost; now in the third era another disaster is beginning. Viruses born in the Altar of Apostles have begun to appear, though normally not in physical form have now taken on the form of monsters and could destroy the world.
