The continents drifted together again and the supercontinent formed.

12 Kings took over the new world and divided the continent into two big parts due to the never ending fighting between them. The Southern Lands and the Northern Lands. These two parts had been devided into 12 smaller ones and the 12 kingdoms were founded. 

Each king has his own supernatural power, which his son will inherit as soon as his father thinks the heir is old enough to take the responsibility for it.
The population is horrified. The treatment they got from the kings and their soldiers was horrible. 

People were beaten up, and even killed. They hated the royal families. But not even all of the humans together could stop at least one king. 

All they could do was being quiet and hope for a better king. For a better future. For a better world.
