Catherine, my love. I have to leave quickly, something terrible has happened. It's hard for me to believe... most of my books have been destroyed.
Catherine, it is one of our sons. I suspect Achenar, but I shouldn't leap to conclusions... I'll find him and Sirrus as well.
Oh, I should have known better than to have left my library unchecked for so long!
Well, I have removed the remaining undamaged books from the library and placed them in their places of protection. You should not have to use the books until I return, but... if you've forgotten the access keys, remember the tower rotation.
Oh, and don't worry Catherine, everything will be fine. I'll see you shortly. Oh, and erase this message after you've viewed it, just to be safe.
