@NoNickNeeded It is kind of a burden, at least in my opinion. Anna passed a huge responsibility onto her descendants, and made it clear that they couldn't afford to make even the tiniest slip up (such as losing the book, not being able to find the keys, etc.). Keeping that book for 400 years must've been kind of difficult, no?
