Mu originally came from East Continent but due to the Great Flood, it sank, making her unable to go back to her hometown.
Mu also is one of the Yin-Yang Masters which usually never leaves the East Continent, but while she was working a commission for a client she broke a very expensive family heirloom leaving her into a huge debt, and to escape it (because she can't pay it) she ended up on the Arc Continent.
