Not an update, but some info adding.
The game for the moment will be named. Didn't work much on the story yet, but Darkhunter helped pretty much on this. Just some background story:
A hundred years have passed since Twilight Princess. The legends of Hyrule tell about an Eclipse that will indicate Ganondorf's return, but at the same time, the Hero of Twilight will reappear and gather the three Twilight Gears (thes WON'T be definitive. They're placeholders). The day for the Eternal Eclipse is approaching, and none has appeared with the three Twilight Gears. Link is called by Zelda during a dream, saying that the spirit of the Hero of Twilight resides in him, and that has to recover the three Gears. During his quest, Link'll meet Sahasrahla, who'll tell him the place where each of the Gears are.
After that, Link will go to the Moon Temple to place the three in their place, just to find out that it's too late: the Eternal Eclipse is happenning and Ganondorf will be back. Though, Link places the three Gears, and the Eclipse happens, but not in the correct way. Ganondorf does come back, but the Eclipse finishes. During the process, Link turns into his Wolf form. During the game, during nights, Link'll become a Wolf, as he can just stay in that form while in the night.
Then, Link'll return to Sahasrahla, who'll tell him that Ganondorf will try to do the Eclipse again to get all his power back again, but for that, he needed the 7 sages to be asleep, as they were the only ones able to erase the Eclipse in a zone. During the process, different locations will be affected by the Eternal Eclipse, and will remain always in dark, until Link awakes the sages.
Finally, Link'll go back to the Moon Temple, and confront Ganondorf in an epic fight in which Ganondorf will be sealed in the Eternal Eclipse.
