Here's my concept:

Far East and Far West
The Far East and Far West are actually not far apart. After the technologically advanced Far West makes their appearance in the twin continents, adventurers find themselves walking into an Empty-Stricken Far East and exploring these two new continents. The story goes like this:

The Far East is a desolate wasteland, where mostly Empty roam. A few survivors of this guard their city from the Empty, but the land and buildings is a frail waste. The Far West seeks help from adventurers to stay the Emptiness from consuming their continent as well, so they and the adventurers seek to save the Far East to preserve their homeland as well.
