Thousands of years ago, an ancient prophecy was told.
It was a prophecy that set two clans with no conflict against each other and made them mortal enemies. It drove them to clash swords and eventually to the war that finally ended with the past encounter.
Yet…how could one be so sure that the war was over?
The Black Dragons sent an army to Beast Emperor Star, but they didn't invade with their entire race. There were still several hundred million Black Dragons in their homeworld, including their Demigod Ancestor.
Of course, this wasn't common knowledge. To most, the last of the Black Dragon Clan was locked away in the depths of the world.
Those with power could never rest as long as the Black Dragons remained unruly.
They needed to be thoroughly tamed.
This thought led to another question: how could one tame a clan that both concealed themselves well and had the backing of a Demigod?
