Konoha. Kiri. Suna. And now Uchu. Bar had conquered the entire land of ninja, largely without conflict. Throughout the nations, everyone was receiving an post-event education on how human nature allowed Bar to control them, how material wants and needs produced suffering, whether mental or physical. The only alternative was to transcend, to leave the material world behind, and enter the Land of Spirit, which Ninshuu allowed one to do. Most ninja cooperated, either out of desire for enlightenment or the desire to leave suffering behind, and with the world's chakra-users all doing the same thing, all life, human, animal, and indeed, the whole planet, became entities of pure energy, leaving their respective lands behind.
Only to find out that Bar had conquered the Land of Spirit as well. DUN DUN DUUUUUUN!
