Dunes

The hoverboard flew over the prairies with incredible speed. Our destination was the Sea of Demons and we didn't have much distance left before we got there. It would have taken us a month of travel just to get there by running but now we can cut that time tens of times over.

It took only half a day before we realized we entered the Sea of Demons. And it was not the prettiest sight to see after leaving a full land of green.

"What's wrong with the land here," I frowned as looked around. 

The massive grasslands seemed to disappear and were replaced by deserted lands that extended as far as the eye could see, and in the extreme far distance was a cloud, a cloud so dark and big that it seemed to cover the entirety of the horizon.

"We entered the Sea of Demons. This is the rim of the region, the closer we get to the center of it the more you'll realize why it was called the Sea of Demons," said old Fu.
