I took the secret part to mean "don't show it to people, since they could get hurt." This isn't my main reddit account, and if anything is watching my browser history, they will see that I'm still making a good faith effort to protect the book, not destroy it.

Yes.. I had the same horrifying thought. I don't think the pages are regular paper.

ok this is the advice I was looking for. I already have a humidifier, and my home doesn't have an attic. It's just chilling in my room right now in a mini safe. I think making a tiny room inside a closet might be a good idea where I can create an ideal temp/ humidity scenario.

I don't want to take it to a professional, because that would potentially expose another person to its power..

A secret floorboard compartment is a great idea. Will look into that

I like the idea of music! You never know what might make it feel comfy.

Not a bad idea. I will look into it.
