Void Gives Wings

This vast continent, known as Iseland by the world, has been divided and balanced by two original forces since the beginning of the world - the holy light of bright order, and the void of chaos and freedom. For hundreds of millions of years, the two forces have been mutually reinforcing each other, maintaining the cycle of life and death of all things in the world and the changes of the four seasons, creating the most primitive and fair balance between heaven and earth.
