"In my imagination, Zelda held the Light and Gannon the Darkness. They say to keep balance both are needed.
What if the original Gannon and Zelda were once friends who undertook a quest to help the three goddess keep Hyrule in balance. And at the end of their journey, it was Gannon who made the ultimate sacrifice -- to take all the darkness within himself to spare Zelda, knowing that he would die over and over as a figure that everyone would despise.
Zelda could never kill her friend and so created a hero (our Link!) that would rise up when ever Gannon would reawaken.
In my imagination the story holds a bit of sadness, because in it..Gannon would be the only one who would remember the true legend of Zelda and their quest for balance. Zelda, in her light, would be reborn only holding her duty and compassion for a lost soul who must be stopped."
I saw this story and post on tumblr, and found the original fanart and story HERE
and I absolutely love this idea, so I wanted to draw something for it : )on Tumblr
edit: before I get a million comments about skyward sword, yes I know this isn't plausible but I still like it a lot.
