070. Territory of Utone Kingdom.

The Chaos era is an era that ended 1000 years ago. In that era, humanity could only survive as nomadic tribes or clans.

Evolved monsters, scattered demons, dragons as big as mountains.

 It was almost impossible to survive in that era. 

Children who could already walk were required to be able to fight. Those who could use magic were brutally trained to protect their clan. 

Farming and plantations never existed in that era. Everyone survived by hunting anything that could be eaten. 

Those who couldn't fight would never see tomorrow.

That era ended when Arthur summoned. A hero from another world who was able to defeat all existences that threatened humans, including the demon king and dragon king. 

The chaos era ended and the peace era began. Slowly but surely, humanity dominated all of Terra and many kingdoms rose and fell during the peace era.
