The Haron Continent...
The Central of human civilization in the Nexus world.
It was not always called Haron and the history books tell of a time when the Harons were but rulers of a kingdom rather than an empire.
At that time, the twelve Duchys were twelve kingdoms. Twelve human kingdoms ruled by Kings and Queens.
The Harons made the thirteenth.
And then the Dystopian continent waged war against humanity and for that reason, the First Emperor arose and sought to unite the Twelve Kingdoms.
They did not always accept to do so peacefully and could not be blamed, after all, should they agree, they would be subverted under a higher power.
It was something they could not accept.
Some fought to retain their prestige.
Some fought to retain their heritage.
Some fought because they were battle crazy.
Whatever the reason, only two kingdoms swore loyalty to the First Emperor peacefully.
