In the ancient time, many isles were driven toward the center of world. Then they formed a whole continent separated by a huge mountain range. Residents of both North and South continent lived peacefully together on the same land. Until one day, a war suddenly broke out. The allied forces of North attacked the unprepared South residents. Thus, Kingdom of Forest became the last shelter of these homeless people. To get back their home, an organization named [Glorious Shield] was established to fight against the North force.

No one knows when this war stops...
