Long ago, the world was a place filled with chaos.
Violence was everywhere.
Fights broke out for even the silliest things.
It was like the world itself took offense for even the most minor of inconveniences.
Some thrived on this chaos and some fell in the shadows. The ones that lived of the chaos really lived off it. They trained the best warriors to feed the chaos and make the world more thrilling.
Because... Without chaos they were nothing, and they knew that so they valued strength over anything else because with strength comes chaos and with chaos comes power.
