Hm? Can I help you with something?

(You tell Karen about the strange book, and the blue piece of paper with MENEOS written on it.)
...'MENEOS', you say? Could it be the owner of the book, maybe they left a note for us foreigners? Then again, I can't even tell where they would be from, with that language...

No, I've never seen such a book nor such a language before.
The way this tome is refined, it must be very important for someone or something. I don't like the idea that something I don't know is sitting unattended in my tower.
Leave that book to me, I want to study it... You can come back later, okay? I'll share my findings with you, as a thank you gift.

(You leave the book to Karen... Maybe she will learn something interesting from it.)
