Hi, new guy here. Sorry to bump (though it's kinda hard to avoid that when the first page stretches clear back to April), but I have this one epic Zelda fic idea that I've yet to do something with, and I figured I'd throw it out here to see what people thought.
It follows the premise that the timeline "splits" at the end of Ocarina of Time. One half of the timeline continues forward from the moment Zelda sends Link back in time via the Ocarina. Hyrule has still been ravaged by seven years of Ganondorf's reign and Zelda has to start putting it all back together. Some centuries down the road, Ganon breaks free of the seal placed upon him by the Sages and runs amok again. This results in the events that precede Wind Waker: the people appeal to the gods, the flood, etc.
The other half of the timeline starts the moment young Link arrives back in the Temple of Time at the end. We see him, during the final scene, run back up to little Zelda in the courtyard of the castle. That means that he was returned to a point in time before Ganon made his bid for the Triforce, before Zelda and Impa were forced to flee, before Link went about collecting Spiritual Stones to open the Door of Time. I'm not exactly certain of how it works, but Ganon once again goes for the Triforce... except this time he's captured, which leads to the "sentencing" we see in flashback in Twilight Princess. He's sent into the Twilight Realm and centuries pass.
Now, at the end of TP, Ganondorf dies. We see the Triforce of Power vanish from his hand. In previous times, the Triforce of Power would have sought out another chosen by destiny to be its vessel... but instead it is drawn like a moth to a flame, wandering for a year across the boundaries between worlds...
...until it finds Wind Waker Ganondorf, imprisoned in stone at the bottom of the sea. He's still the embodiment of Power, so it is drawn into him automatically. He suddenly has vastly more power than before and almost instantly breaks free from his imprisonment, triggering an earthquake that ravages the islands of the Great Sea.
Meanwhile, back <s>on the wranch</s> in the TPverse, strange things start happening. Parts of the kingdom seem to be vanishing, replaced by voids not entirely dissimilar to but at the same time distinctly different from the Twilight Realm. Basically, without the Triforce of Power, something is blatantly out of balance in the world and it's coming apart at the seams.
Each Link and Zelda from each world, WW and TP, wind up having to find a sacred artifact in order to solve their respective problems... except their respective artifacts aren't in Hyrule at all, they're in the Sacred Realm. And the only way to the Sacred Realm is through the Temple of Time (the actual dungeon as seen in TP, though I like to think of it as the Temple of Light that was mentioned in OoT). TP Link and Zelda just go back there, but WW Link and Zelda have to find the darn place first. The only things left of the Temple of Time when they find it are the Master Sword's pedestal and the Door of Time. They enter the Temple just like TP L&Z do.
...and now I think I might've gone into too much detail, but I dunno. I'm not sure if I'm ever actually going to get around to writing this; it's been years since I wrote anything on this kind of scale.
