The continent where monsters and demons gather seems peaceful, but is full of dangers everywhere. Thousands of years ago, there were four artifacts in the northernmost part of the continent. Humans and monsters wanted to destroy these four artifacts, causing the earth to collapse and all life to be destroyed! The people were miserable. In the final battle, the demons grabbed one, the monsters grabbed one, and the humans grabbed two artifacts. Under the checks and balances of the artifacts, they did not dare to take action easily. A no-war treaty was signed, and a new crisis lurked behind the crisis.
