Now this was an idea I was playing around with shortly after reading
Tri-Timeline Plus
I started trying to think of what could cause a second split in the timeline and I think I might have found a plausible answer to it. Now I know almost everything in the original theory there and mine go against alot of current Zelda beliefs but it doesn't really contradict any rules.
Now this part is a given:
........WW-PH
OoT-
........MM-TP
Now for the sake of this timeline place MC before OoT. It is kind of needed there to make this work.
CONFUSING PART! Be warned!
The orginal split is quite obvious at the end of OoT. Child and adult ending. I am taking that a bit further. In the child ending Link seems to return before his first meeting with Zelda and he procedes to warn the kingdom of Ganondorf (acording to generally accepted theory). His time travel is also what splites the triforce in the child line. Now since he returned before he orginally left. There SHOULD be two Link's walking around. So there should be a Link warning Hyrule and a Link in kokiri forest. Now when Link prevents Ganondorf's plans he is effectivly destroying the purpose of the hero of time. If Ganondorf doesn't cause all the trouble, there is no reason for Link to go questing for the spirtual stones and drawing the Master Sword.
This huge paradox of being two link's at once and the future Link destroying the reason for his current state of being create a new timeline.
The Link that is still in the Kokiri forest is "rejected" and the timeline is split from there. This Link, while still biologically the same Link as before can't be the hero of time. As the position is already filled by himself in the other timeline. This would mean any events relying on the HoT can't happen. Thus Ganondorf never follows Link into the sacred realm and never gets his Triforce piece. So at the end of the day OoT never happens here, Adult of child side.
So now this beast looks like this

So what goes there? I propose that FSA (and thus FS) fit the place. Ganondorf is in the game and is after the Trident of Power. Assuming he gave up on the Triforce (because he can't get in the SR at this point without the Hero of TIme to pull the MS.) This timeline leads to all of the games featuring the "blue" pig ganon.

The Link in FS/FSA is possibly the "rejected" link from the 2nd split. Seeing how he is still destined to leave the forest because he is a Hylian. However there is no evidence at all for that and it is pure speculation.
Now I am not fully convinced this is the way the timeline actually is. I normally support a two way split with the 2d games in the child line. The developers probbaly haven't even thought a 3-way split. But it was fun and challenging to work with a new idea. If this theory goes well I might adopt it as my "official" timeline, but I doubt it will. Just try to think outside the box for this one and forget about traditional theories.
I do like the fact that this allows much more flexibility as far as Vatti and Zant are concerned.
Edit: Link fixed
