During a fierce storm, Grandpa begins to tell a story...

On Nourania, a distant planet, an Emperor is nearing his death. Before breathing his last, he makes a terrible confession to his son. Naran, the Emperor's son, receives the Blue Planet as a gift, in exchange for Nourania, which is about to be destroyed.

Zoar, the Emperor's successor on the Blue Planet, is forced to leave everything behind, except for the Inheritance. Accompanied by his family and guided by the Blue Flame, Zoar will go into exile and seek another realm, becoming the founder of a new order and a unique kingdom.

Still, he will have to pay a dear price for the land bestowed upon him.
