I found it. This is what Robeira asked me to keep. She said it's a good book so I read it several times. It's so hard for me to understand!

When you're finished reading the book, would you please give it to Grendel the Really Old of Ellinia? Robeira has kept this book quite a long time. Robeira said it's ok to give the book to Grendel the Really Old. Thank you!

Thank you. This book is very old and you need be extra careful with it.

Ah... You look busy anyways...

Oh. You brought the book. Thank you. Although I study spells in [map 101000000], I sometimes feel frustrated. We have various books to study, but it's still hard to be a master... That's why I looked for this book.

What kind of book is this?

.......

It's hard to explain about this book. If you really want to know, please come back. I need time to think...

After reading the book, give it to Grendel the Really Old.

Welcome! Are you here to study spell-casting?

You picked up before. Because it is Robeira's, it is meant to be returned to the library. Be careful. There are many out there who need to read this book.
