Have They No Shame?

Archmage Berinand is the Kirin Tor's foremost authority on Malygos. He's spent his life studying the aspect and his behaviors. Recently, he loaned me his research on the Arcanomicron, some sort of map that Malygos is trying to assemble. I made the mistake of discussing it with a group of Alliance adventurers while they were restocking their goods here - and now it's gone! It must have been them, <Class>. Please, follow them into the nexus and find the book before Berinand comes to recover it from me.
