It was not until 20 years ago that the swordland was freed from war. The peoples of the continent have been accustomed to fighting in groups since ancient times and to settling disputes through war. And at all times, the tools of war are magic. The army armed itself with magic and in writing, and heroes created most of the magic objects leading forces to kill each other. The summoners, the actual guides of the waroran continent, used their magical energy to attack the forces and supporters of the enemy. They have an almost infinite force of primitive magic, and they have never considered what the endless misuse of magic would do to the continent's environment. The last two battles have dramatically affected the geological environment in varolam, and despite attempts to gather magical energy to restore this disastrous outcome, they have not worked. This fear is far greater for people than the horrors of war. It was finally recognized that the world could no longer afford the devastation of the war. In response to the worsening political and economic crisis in the world, the great magicians of varolán — including many powerful summoners — reached a consensus that all conflicts must be dealt with in a manageable and systematic manner. They set up an organization called "100,000 light years" to monitor the orderly handling of political disputes in varolán. The 100,000 light-years at the war college have been authorized by the voloran political entities to manage the outcome of all political disputes, and 100,000 light-years have determined that all major political disputes must be dealt with specifically in the arenas throughout varoran. Callers with political dissent call on one hero each, and those heroes lead unwitting soldiers in battle, who are made from the nodes of the first callers。
