Will there ever be an age without a war...?
Dreams and magic have no meaning without a civilized world...
The ignorant ones always strive for power, never realizing that what lies beyond is despair...
But maybe they will bring with them hope, and show us a new way of life...
God bless the visitors from the land of dreams and magic... and glory to the soldiers of light who will lead us to the new world.
