Hello Adam! It was interesting to watch your four-part video timeline, and here are my comments. Some might have been said before, but anyway.
The Minish Cap
The way I gather are the absence of the Triforce (well, the Triforce is depicted in several palces in the game, though) and the absence of Ganon not per definition timeline indicators, as for example evidenced by LA and ST.
The useage of the sentence "The legend will continue" as evidence that all other games follow TMC seems strange when SS is put before TMC. But you might have another opinion.
I think that it's clear in the game that the Minish brought the Light Force and the Picori Blade to
the Hero of Men, which is supported by the fact that he is kneeling below the Sword and the Light Force.
In TMC, FS and FSA, it seems like Hyrule is a united kingdom. That doesn't make much sense if they take place before OoT, since the land was only united some 7 or 8 years prior to the start of the game. What do you think of that?
I didn't catch how Ganon got out of the FS before OoT. Would you like to elaborate on that?
The Imprisoning War.
(The Master Sword was actually forged before the Imprisoning War, that was one of the mistranslations that were corrected in the GBA re-make.)
Let's take a look at the quotes regarding the IW and the AlttP BS.
(Lanayru's story in TP)
For ages, the people lived at ease, content in mind and body… But soon, word of the Sacred Realm spread through Hyrule, and a great battle ensued… Among those living in the light, interlopers who excelled at magic appeared. Wielding powerful sorcery, they tried to establish dominion over the Sacred Realm. It was then that the goddesses ordered us three light spirits to intervene. We sealed away the great magic those individuals had mastered.
This allows us to construct this timeline
The word of the SR spreads --- Great battle --- Interlopers are sealed
Moreover, the Interlopers tried to "establish dominion of the Sacred Realm", but the Light Spirits intervened and sealed away the Fused Shadows and eventually the Interlopers themselves, which suggests that they didn't gain access to the Triforce, which in turn makes it hard for the Interloper Conflict to be the IW. Also, if the Interlopers was sealed in the Twilight Realm, how could Ganondorf be one of them?
Let's go on with the IW.
Only a select few knew of its location, but at some point that knowledge was lost... The person who rediscovered the Golden Land was Ganondorf the evil thief.
This is interesting. This quote tells us that there was originally other people than Ganondorf who knew about the location of the SR. Since the Interlopers knew about it, their sealing needs to take place before
Ganondorf enters the SR.
The word of the SR spreads --- Great battle --- Interlopers are sealed --- Knowledge is lost --- Ganondrof rediscovers the SR --- IW --- AlttP
The main events of AlttP need to succeed an event in which Ganondorf can rediscover the SR and get sealed. The only times we know he has done this are OoT perhaps FSA.
The problem with OoT being the IW is mainly that the Triforce is not complete in the end and the main problem with FSA is that Ganon doesn't find the Triforce at all.
The most logical conclusion, in my view, is that the IW is a separate event. I believe that it takes place after FSA, with FSA Ganon breaking out of the FS and gathering a band of thieves and eventually finding the location of the SR, but that is another theory.
The Triforce is said to be complete when three pieces are united, which indicates that there are only three pieces. There was also three goddesses and they left one piece each. We can also look at the absence of any fourth piece to reinforce this view.
I believe that the general counter-argument against the "Four Light Sprits = Four Goddesses"-theory is that neither Faron nor Ordona has the name of a goddess in their proper names, whereas the two combined almost makes up the name FAR+OR(E).
The "inverted triangle" from TMC is actually the Light Force (which does look very similar to a Triforce piece), but whose relationship to the Triforce is unknown. It can have a connection to the Triforce, though.
The Master Sword and the Four Sword
Let's talk about the "Palace of the Four Sword". In the PotFS we can find the Four Sword, and since Link already has the Master Sword, the swords can't consequently be the same. If the PotFS is canon, then the two swords are separate.
Moreover, the Master Sword was not created by the Minish, it was actually created by the Sages, which indicates that they are not the same swords.
The Split Timeline
You have probably seen this quote before, but:
Question: When does Twilight Princess take place?
Aonuma: In the world of Ocarina of Time, a hundred and something years later.
Question: And the Wind Waker?
Aonuma: The Wind Waker is parallel. In Ocarina of Time, Link flew seven years in time, he beat Ganon and went back to being a kid, remember? Twilight Princess takes place in the world of Ocarina of Time, a hundred and something years after the peace returned to kid Link’s time. In the last scene of Ocarina of Time, kids Link and Zelda have a little talk, and as a consequence of that talk, their relationship with Ganon takes a whole new direction. In the middle of this game [Twilight Princess], there's a scene showing Ganon's execution. It was decided that Ganon be executed because he'd do something outrageous if they left him be. That scene takes place several years after Ocarina of Time. Ganon was sent to another world and now he wants to obtain the power...
The Ocarina of Time:
According to the Split Timeline theory, there are of course one Ocarina of Time on each timeline.
AT: Zelda gives Link the Ocarina --- Link defeats Ganon --- Link and Zelda are on a cloud, Link gives the OoT back and goes back in time
The exact moment Link returns to is subejct to much debate, but here is my view
CT: Link is brought back to the moment before the drew the MS --- Link goes to Zelda --- Link gives her the Ocarina --- Zelda gives him the Ocarina --- Link goes to Termina
The Moon and the AT
I can see two possible solutions to this problem:
1) Termina has its own timeline and is not affected by the split.
2) Skull Kid never gets Majora's Mask on the AT, consequently eliminating the problem.
This is the re-translation of the King of Red Lion's speech. Translated by Archer on Zelda Legends (second line is NoA, first is re-translation)
Link, do you know the legend of the Hero of Time?
Link, do you know the legend of the Hero of Time?
Long ago, the Hero of Time defeated Ganon and restored peace to Hyrule. He had a Triforce dwelling in him just like Zelda.
Once, long ago, he defeated Ganon and brought peace to the Kingdom of Hyrule... A piece of the Triforce was given to the Hero of Time and he kept it safe, much as Zelda kept hers.
It was called the Triforce of Courage. It is said that when the Hero of Time traveled through time and left Hyrule, he was separated from the source of being a hero and the Triforce of Courage turned into 8 fragments and scattered throughout the land.
That sacred piece is known as the Triforce of Courage. When the Hero of Time was called to embark on another journey and left the land of Hyrule, he was separated from the elements that made him a hero. It is said that at that time, the Triforce of Courage was split into eight shards and hidden throughout the land.
Here we can see that it's clear that when the HoT left the AT, the ToC split. This is the reason why there were no hero to stop Ganondorf: Link didn't exist on the AT(!). Thus, WW takes place on a different timeline than the one the HoT went to, which we know is the one that leads to MM.
Legend of Zelda and Adventure of Link
I don't think we have any evidence that either Old Hyrule was unflooded or that any Hyrulian King got the Triforce, which means that the placement of LoZ/AoL becomes a bit problematic.
A Link to the Past
We know that the Triforce is in the North Castle at the end of AoL, not in the SR, as it is in the beginning of AlttP, which makes the Triforce progression between AoL and AlttP a bit strange. Moreover, Ganon is dead in AoL, whereas he is sealed in the SR in AlttP, which makes the Ganon progression a bit strange, too.
Another question: Woudl you like to explain how can the old landmarks of Old Hyrule have remained more or less the same even though the land has been flooded twice (before WW and in WW)?
All this makes me doubt that LoZ/AoL is a prequel to AlttP.
Firstly, we know that TP is offcially a sequel to MM. But nevertheless:
Let's just take a look at Ganondorf's back story.
His name is… Ganondorf. He was the leader of a band of thieves who invaded Hyrule in the hopes of establishing dominion over the Sacred Realm. He was known as a demon thief, an evil-magic wielder renowned for his ruthlessness…
Ganondorf invaded Hyrule to gain access to the SR. But, how can that work if he was in the SR, as you suggested? Also, Ganondorf was not known as the "Great King of Darkness", but as a "demon thief" who commanded a band of thieves, not an army of darkness. I can not see how TP Ganondorf can have experienced LoZ, AoL, AlttP and OoX. But, please, explain that if you want to.
I hope that my comments can help improve your timeline.
