MAPS

This is Kashonai. Don't think that Kashonai has broken into parts but it was like that before the shadow attacked. (Come down......)
This is the map of the world before the shadow attacked. The types of ninjas were living separately until the shadow attacked and all the countries decided that they should join together and be one country to stop the shadow. So now the shadow one are trapped inside THE KASHONAI.
