Tentivu is a large continent dominated by a culture all about cardinal directions and the four elements. There's ten countries spread over four kingdoms - one for each element.
The geographic extreme points of each kingdom (north, east, south and west) are of special significance, and from them emanates a grid of curvy Ley lines and concentric circles illustrating the sheer magical power gathered in those places.
Distances are vast, but wealthy and magically talented people can get by using a form of magictech that allows them to shorten the travel time considerably.
This map is only a small part in a massive world building project, and I consider it a huge honour to be part of it, even in such a modest way.
