So it turns out that Nintendo may have offered up more information on The Legend of Zelda: Breath of the Wild than they intended to. By revealing a map that comes with the collector's edition for just a split second, folks have pulled out all sorts of information that looks to explain what's been going on in Hyrule leading up to the beginning of the Switch launch title.
It should probably go without saying but, if you want to remain totally spoiler-free on all things Breath of the Wild until the game launches on March 3, then should stop reading now. But, again, this information pertains to the new Zelda's backstory, not the plot of the game itself.
Long story short, if you pick up a copy of Breath of the Wild's Special Edition or Master Edition, it will come with a cloth map of the region with all sorts of extra little details. One of those details is a pretty lengthy paragraph that YouTube user Zeltik freeze-framed and actually translated from an in-game language into Japanese, according to Polygon, and then translated that into English. Assuming he isn't just making the whole thing up, we don't read Hylian or Japanese, here's what it says.
Hylians pass stories of a destined time long past where multiple races lived and worked together in harmony. The Sheikah Tribe's blue aura breathed through the land and this mutual prosperity continued until a cataclysmic disaster stuck. The Hero and the Princess attempted to seal the terror which became known as the Calamity Ganon. Divine beasts awoke from four directions and deployed a mechanical army which made the King and his people fearful. They fractured Ganon's power and sealed him, but the Sheikah were banished from the land ever since.
Again, not a super deep look into the world of Breath of the Wild, but it at least gives us a better idea of the events leading up to the game. We assume all of this stuff happened in the way-way-back, as is sometimes the case in Zelda games. Usually, the current princess, Zelda, and a new hero, Link, must fight back to seal away Ganon a second time. Sometimes it turns out they were also the first princess and hero, too. Sometimes time travel or alternate dimensions are involved...It's complicated.
After going over the process of translating the map text, Zeltik starts to discuss what he believes all of this means for the new game. Obviously someone has released Ganon so that he may wreak havoc once again, and those monsters and mechanical beasts have returned. We're going to go out on a limb of our own and say that Link's purpose will be to fight back against the baddies, maybe bring the shunned Sheikah back into good standing with the rest of the world and, in the end, lock Ganon away "for good."
We suppose we'll just have to wait and see.
