Once upon a time, there existed a large continent in the middle of the largest ocean in the world. The continent was called Mu, a place where human civilization also thrived. It was located in the vastest body of water on earth and there seemed to be an invisible barrier causing shipwrecks for the expeditions of the other continents so no outsiders had discovered it.

Of course, while entry was impossible, exit was not. So those curious inhabitants who wanted to explore the world could do it, and they did.

The only problem was that they would bear divine punishment once they decided to tell others about Mu's existence. They would forever forget about their home continent, their families, and sometimes, even their names. They would also receive the same punishment if they didn't come back within a year.
