Whatever Happen to Phi the Skyward Sword?

[Cococrash11]

In Skyward Sword it will reveal the origin of the creation of the Master Sword. It was once the Skyward Sword and Phi a humanoid representation of it and It got me thinking what ever happen to Phi in the future? Why can't Link (Skyward Sword)'s descendant see Phi? Maybe it will got something to do with the making of the Master Sword and when the game is released maybe it will revealed why.

What do you people think?

My guess is Phi scarifies herself for the mastersword. So the reason descendants cant see her, is that shes dead!

We know the Skyward Sword becomes the Master Sword. Perhaps Phi merges with the Skyward Sword to become the Master Sword? =\
