The world of Fulheim is sustained and has prospered through its use of a luminescent technology known as "leys," the source of all magical energies. However, the world totters on the brink of collapse as creatures from outside wreck havoc and inner turmoil threatens order and peace. Amidst ever more frequently occurring riots, creatures called "Contaminant Dragons" pose the gravest of threats to the empire of Meridian. As the creatures increase their numbers the environment quivers with a strange phenomenon known as "crystallization." Reports from across the world credit the mysterious pollution to these monsters, yet killing them would only unleash another series of disasters, as their very bodies poison the air upon death. When word reaches the empire of Meridian that a flight of dragons are en route to the capital, it is up to Bright, a soldier of the imperial army, and Alse, the second prince of Meridian, to repel the danger any way they can. During this period of global turmoil everyone fights to restore harmony. They have yet to find out that it comes with a very high price.
