Unfortunately, the Ryslig peninsula has not traded with other countries for almost a century, due to the fact that the peninsula is cut off from the rest of the world. Not that there would be any countries to trade with--prior to the current Ryslig timeline, certain events occurred that brought forth mass destruction. As a result, Ryslig is the only thing that has survived. However, this information is only known ICly by high-ranking Fog Priests--the citizens of Ryslig just think that they're simply unable to leave.

However, it wouldn't be out of place to say that with the increasing presence of monsters from various dimensions, Bavan has become somewhat of a melting pot. Although it still has strong roots in its pseudo-European culture, you might find an enterprising human trying to open a ramen shop based on what they've learned from other dimensions.
