The Other Realm is another realm that exists outside of Fantendo. It was mostly destroyed during the Atomic War, but some people still live in the ruins. Demons also make a huge part of the remaining population.
The Atomic War
The Atomic War was started due to the fact one man managed to get hold of some creatures which watched over the realm and used them to take over. Nobody took the invasions very well, and soon the whole world was in war.
The man was eventually killed, and the Nymphs could return, but the rest of the world was still at war. After the war finished, mostly due to the fact that mostly everyone was dead, Las Vegas opened into a hellhole and demons took over.
But a portal was opened, and the creatures who lived there went into it...
