Majora -> Fourth Peice Link?

[bootson 2]

Majora was defeated, remember? The happy mask salesman said that the evil had left the mask so Majora WAS destroyed, and Majora WASN"T a god, to weak, and pay attention to the story in Ocarina of Time, only the three goddessess are mentioned

[Sahaqiel 1232]

Just because Majora was defeated doesn't mean it couldn't be a Goddess.

This is a very good and well accepted theory on why Termina seemed doomed from the start, and guesses Majora's role in Majora's Mask in a way that makes perfect sense.
