Hey, it's you again! Well, I mean you - as in the you that is <name>! Yes - that you!
Hey, let me start over!
That object you found in Silithus - it was in fact a book. It was a journal written in a very ancient dialect of what we now call the Darnassian tongue. It'll take a while, but I'm going to go over it very thoroughly. I thought you should know that what you found was extremely valuable for the Circle.
