Follow the Elemental's Revelation

I felt like some place further on was calling me. A tree in Yaran suddenly came to mind. The book must be buried there. If I acquire the Book, I'll take it to Roin Bigmouth north of Gizleback Village.

I checked again, and I was right. I should find the Book in a tree in Yaran and take it to Roin Bigmouth north of Gizleback Village.

You brought it! My dream has come true. What? Oh, yes, I know. I can't do all those spells right now, but you don't know what it means to sorcerers to get something we can do more research on. You did great!
