A thousand thanks.

Shaella speaks to me and after I said that I didn't find the book she confirms that I have now found it....
so it ends like this? Shouldn't Hasdar appear?
Maybe the problem is due to the fact that I talked to Haeball before talking to Shaella and since he became aggressive I had to eliminate him...
but if the quest is over like this I'd rather not spend any more time on this topic.
