Questions about Teeth of Naros (Kingdoms of Amalur: Re-Reckoning)

There are two of them and they are quite interesting.
1.How to get the third twist of fate? On the Internet it is written that you need to research the Teeth of Naros well. I researched everything I could - the result is 0. What is needed to get this twist?
2. Strange Almain. Where is the book he asks to bring?
Thanks in advance!
