Next Up, Majora's Mask

Yes, for the next few days, I will be posting Majora's Mask theories. First of all, I'd like to say that I will not cover the "Sad Tree is the Deku Butler's son" theory, as it has been confirmed by Word of God. I will, however, be covering such theories as:

• Majora's Mask was made by the same creators of the Fused Shadow.
• At the end of the game, Link uses the Elegy of Emptiness to revive Mikau, Darmani, and the Deku Butler's son.
• All of the masks are trapped souls, rather than just the transformation masks. 

I will also not cover anything regarding Termina as anything other than an alternate universe, seeing as how Word of God (and the manual) state clearly that it is exactly that, made with "leftover creation power" from the 3 goddesses.
