From the post:
The 3rd World War was referred, by many, as the last war because of the vastness of destruction that it had caused. Everywhere around the world, mankind suffered great casualties and horror — but a few survivors that had the power and the resources built mighty cities all around the world to gain strength and rule again. The cities that were built each had a unique aspect: They contained golden metallic walls, symbolizing hope. Thus, they were named the Golden Cities. This game takes place five years after the Last War, with the players taking on the role of people vying for citizenship within a Golden City.
