Far West of the high-level lands was completely barren, there wasn't any trace of life. The reason for this abnormally being the sky-changing border between middle-lands and high-lands was located here.
Furthermore, the sky-changing border here wasn't like the low-sky changing border between middle-lands and low-lands, because even if someone had a sky-changing pass they can still die while crossing it!
The reason for this cause was unknown, but it all started over a hundred years ago when a powerful emperor tried to take control of this massive formation, as for the reason behind it, no one knows but the sky-changing border completely changed after that emperor enter the formation and never returned!
Now, the middle sky changing border can only be crossed between a particular period that lasts for three months and after that one had to wait for right months if they wanted to safely cross the sky changing border.
