The scholarly faction and the Netherworld Realm were arch-enemies. Back in the days, after the Scholarly Sage was defeated in the battle for the Will of the Heavens, the creatures of the Netherworld Realm seized the opportunity to launch a powerful attack that almost wiped out the entire scholarly faction. As such, the scholars—who were at the peak of their momentum back then—started to decline.
Then, after going through a long dark age, the scholars slowly started to recover. But, each time the scholarly faction was showing signs of recovery, the demons of the Netherworld would look for them and launch a powerful attack, crushing them again before they could recover their strength.
More than 300 years ago, the scholars decided to withdraw from the world due to the continuous raids, and rarely appeared in front of others since then. Only after several hundred years had passed did they recover some of their power.
