Here is info of story from Terra Battle 2 Official Website:
Evil turns to stone and lay dormant.
The pure will light up and awaken.
An aura too strong gives life to Good… And Evil
To our world… TERRA
Light gives birth to darkness, and darkness gives light its form.
The place to which we must return, the place from where we must depart.
