When Evil attacked the planet of Aria, the twelve forces, Aria's protectors, sacrificed themselves in order to keep it away, as stated by the law, for one's pure blood should be shed in order to seal the evil away. However, the forces' blood wasn't totally pure, for they were human, as its effect wouldn't be everlasting. Their sacrifice sent the Evil away from Aria for a long time. However, the planet split into two others, Aeros and Anthea.

Hundreds of years later, danger looms over the divided Aria once again. The twelve forces are reborn and the chosen should be gathered in order to reunite the planets and defeat the Evil which threatens both. The reunion of the two suns shall begin.
