[SPOILERS] The Contents of a Very Interesting Book in Hyrule Castle
So during a stream on [this channel](https://www.youtube.com/watch?v=Q9IoqnUz19c), the guy finds an interesting book in Zelda's Study inside Hyrule Castle. And it tells a lot of interesting details about BotW. Including that the story told in the tapestry is actually 10,000 years old. And goes in-depth of her excavations and investigations of the Guardians, the Sheikah Slate, and the shrines. As well as the name of the Gerudo pilot.

>Today I met with Impa of the Sheikah tribe and began my research into the ancient technology in earnest.
>Impa introduced me to Purah and Robbie, other respected members of her tribe.
>Tomorrow I embark on an excavation with them.
>We Hope to find ancient tech with which to operate the Guidance Stones.

>Today we uncovered some ancient technology that we believe may have the power to control the Guidance Stone.
>It is a rectangular object, small enough to be held in my two hands. Sheikah text is featured prominently on it.
>It is made of an unknown material, but we believe it is the same as the shrine scattered across each region.
>Impa proposed that I hold on to it for now. I hope that it leads to some new developments in our research.

>The stone relic we discovered has been named. We are calling it the Sheikah Slate.
>We have not found any mention of a name for this object in the records we have unearthed so far...
>Nevertheless, Purah insisted we call it the Sheikah Slate, as the relic is a slate made by the Sheikah tribe.
>Feels a bit on the nose to me, but it was not a fight I thought I could win.

>We did it. We were finally able to restore some functionality to the Sheikah Slate.
>We have discovered that this stone slate is capable of producing...images. Perfect liknesses of the things you point it at.
>Unlike normal pictures drawn by hand, this requires no artist to capture anything in perfect detail.
>I deeply admire the accomplishments of Sheikah technology. Still...I know there is more to learn. There must be.
>We believe the Sheikah Slate may have a function that will allow it to control the Guidance Stone.
>We must continue our research, and quickly.

>We have started training the Champions who will pilot the Divine Beasts.
>It may sound rude that I found this unexpected, but Mipha mastered the controls with surprising ease.
>Daruk struggled at first, but eventually got the hang of it. Urbosa and Revali both managed just fine as well.
>I can finally see the light of hope in our fight against the rising Calamity.

>Robbie has restored mobility to many of the Guardians we've excavated.
>...But we have still yet to find all of the Guardians. Records mention greater numbers of them-and even other types.
>They are said to be stored in five giant columns that rest beneath Hyrule Castle. The thing is...
>No matter how I search beneath the castle, I can't seem to locate these columns. They must be buried deep.
>Were they perhaps designed to sense the appearance of Calamity Ganon and to only activate upon his return.

>Countless ancient structures are being discovered across Hyrule...but all attempts to enter them have failed.
>Records indicate that these are facilities designed to train the hero who is fated to combat the Calamity.
>But the crucial activation mechanism remains a mystery. Is the Sheikah Slate the key to activating them?
>That is Purah's theory, and I concur. And yet, my experiments so far have been fruitless.
>Still, we must exhaustively investigate all means to opposing the Calamity. We must not give up, no matter what!
