There's a concept Brandon Lachmann used in his RPG which kinda mirrored our world. It was called the 'Riddling Incarnate" I think. I can't find the exact document right now but it was something like that. There wasn't a lot of details but it seemed like a philosophy / guiding life principle / religion in his world.
The idea as I understood it is that anything worth knowing, was worth having to work to figure out and uncover. Anything found out easily, isn't worth knowing. Anything really, really important had a corresponding difficulty to learn.
This is why the Book just doesn't outright tell us the fragments or simply open up.
So, you could argue, I suppose, that the Storm is a challenge the Book puts in the way of those who open it intentionally as a way to test them. But...would the book really go so far as to kill, and mentally wipe people as a consequence of this challenge? Man, I hope not.
