From the introduction: Welcome to the continent of Gressen! A land of magic and monsters! Long ago, God created three types of beings: Beings of Light, Beings of Darkness, and Beings of Chaos. Ten thousand years ago, the beings of Chaos mounted a rebellion against God, and upon their defeat, were all sealed within six red stones. Soon, a young man named Yeh Chun-hwa will arrive in the Cursed Forest of Sion, where he will meet an ancient dragon named Greydrone, and his adventure will begin.
