In ages past, the Holy Dragon was annihilated by the Black Dragon, but from his soul, six new dragons were born. Together with the Dragoons, these dragons have been charged with protecting the world. For centuries, all is peaceful, until the day of Dragoon Valen Kessler's graduation ceremony. The Black Dragon appears and destroys the capital city of Granadis. The Water Dragon appears to challenge the intruder but is slapped briskly aside. When it's all over, Valen runs into Euphe, a strange young healer with some connection to the Water Dragon. Together they're charged with the task of ensuring the safety of the world's dragons, as well as uncovering the dark mystery behind the sudden attack of the vicious Black Dragon.
