In the far north, there lies a vast stretch of desert. No one knows where the desert ends.
Within the desert dwell "demons," which have been harassing the human world for countless years.
It is said that during the Ancient Era, there was a demon tide that nearly destroyed the world. It was only through the fierce resistance of the sages that the human race was saved. The eradication of the demon tide is also regarded by many as marking the end of the Ancient Era.
The two strongest states in the north are known as Jingguo and Mugu.
Both Jingguo and Mugu have stationed large armies at the border of the desert to suppress the demon tide.
Thus, this desert is commonly referred to as the Border Wilderness.
It signifies the border of the Human Race, the division between civilization and desolation.
