So during the MSQ you go to the forbidden library with Y'shtola. You read about Voidsent and the Atomos. And maybe I missed it earlier, but..?

How can Y'sthola read the tome? Isn't she, well, more or less, blind? I know she can read and see Aether, but it's a pretty well-known fact she can't see, physically. Like, when that part in Shadowbringers happens and she can't tell who we are, because she only knows us by our aether.

So what's the deal?
