So DJ is working on a map but I made this quickly while he and I and others were discussing where the borders should be, some areas are inaccurate but it gives you a rough sense of the world none the less:

The big three unions that players can join right now are the top three, the blue (Atlantic Union), teal (Eastern Federation), and red (Pan Asian Coalition).

The names of the remaining five escape me but there's one in Central America, South America, Africa, North Africa + Middle East, and then India and the Pacific.
