My site is tomorrowsninjas.heavenforum.org
The setting of this site is 80 years after naruto's death. The reason why there are different countries and villages is that 75 years ago, there was a great ninja war. 15-25% of the total pop. at that time survived. Since there was so much destruction, they started over. The war lasted 5 years. Also, the leaf, sand, and cloud villages are now small villages. There are now new nations and new villages.
