I have read the other questions and answers related to the Zelda timeline on here. But my question wasn't answered there. A few years ago Nintendo finally released the History of Hyrule book. It, after years of speculation, finally connected all the Zelda timelines.
I'm very confused though. In the Ocarina of Time, two timelines emerge. The first is when the hero is defeated. This timeline makes zero sense to me. Of all the times a player can fail in these timelines, why is it that OoT had the timeline split? Did I miss something here that explains that in OoT another major event happens resulting in Link failing his quest?
I mean I know that with the second timeline two more timelines emerge, one follows the events when Link was returned as a child. The other follows the timeline when Ganon was sealed. But in all the games, it's possible to die. I can't remember an event in OoT where I failed and had to repeat the events over that was any different than another Zelda game.
But the event's of Link failing, is this in the event that all timelines the player fails merge into this timeline? Or have they just not covered all the other timelines the player may fail (i.e. if a player fails in the timeline where the player is defeated)?
In the Zelda wiki, this is explained:
Fallen Hero Timeline
The Fallen Hero Timeline is the timeline in which Link, the Hero of Time, despite his best efforts, was defeated by Ganondorf in the final battle. Ganondorf obtained the remaining Triforce pieces from Link and Zelda, and was subsequently sealed within the corrupted Sacred Realm by the seven Sages. This timeline branch contains the events of A Link to the Past, the Oracle series, Link's Awakening, A Link Between Worlds, Tri Force Heroes, The Legend of Zelda, and The Adventure of Link in that order.
Ganondorf obtains the complete Triforce
After the Hero of Time is defeated at the hands of Ganondorf, the King of Evil extracted the Triforce of Courage from Link and the Triforce of Wisdom from Zelda. Obtaining the true power of the complete Triforce, he is transformed into the Demon King Ganon. In a desperate last resort, the Seven Sages seal Ganon along with the complete Triforce away in the Sacred Realm, which was already transformed into the Dark World as a reflection of Ganondorf's evil heart
But why would this be any different in any other timeline? Ganon or minion of Ganon defeat Link, Ganon gets eternal power, and the rest of the events somehow unfold. I haven't found a single resource explaining why OoT is this breaking off point.
