Hero of the Fall.
@maryalice34 @TheGamingKoopa To further clarify, Link does not die to start the Child Timeline, the one where Majora's Mask and so on take place. He dies during Majora's Mask. The event that sets the Child Timeline off is that Link returns after defeating Ganondorf in the future and warns Hyrule of the danger of the Demon Lord before the Ganondorf has a chance to do anything. Link then leaves to find Navi, and this sets of the events of the timeline that you both are thinking of. This is not the timeline I am referring to though. There are three officially outcomes that follow Ocarina of Time: The Adult Timeline, the Child Timeline, and the Hero-less Timeline. The third is what I am talking about. In the third timeline, Link dies in the battle with Ganondorf in Ocarina of Time instead of surviving and going back. This sets Hyrule into a period of decay, allowing for the events of Link to the Past to happen, and so on down that line. The fall of Hyrule, if you will.
