I think Farore created Fi, seeing as she says Link is the one chosen by her creator and the goddess that chooses Link is Farore. It would make sense as well considering this... There is no physical proof yet that the goddess that the Skyloftians worship is Farore, but here are some of my thoughts. Farore is the Goddess of Courage and creator of life and Link always gets the Triforce of Courage. Taking a look at the Master Sword's chosen reveals a pattern. Not just anyone can wield the Master Sword, this much is stated and obvious, they first have to prove themselves. Link in WW gets the Master Sword before assembling the Triforce, this is true, but even with him assembling it it wouldn't go to him unless he was chosen to bear it. Every wielder of the Master Sword is chosen by the Triforce of Courage. Is it a coincidence? perhaps... But history is telling me and showing me that the Master Sword goes only to Farore's chosen... This video is supporting this idea in the way Fi says that Link is chosen by her creator and seeing as how Fi is the Master Sword... This isn't anything that's directly stated, but it is an interesting thought and is just an opinion based on my thoughts and observations.
