Query: Wealth of Information

At first glance it seems a bit pricy but when you open it you realize that the typeset is very small and this book in act contains a huge amount of information. Very useful if your campaign moves over the Dragon Reach and you need some information on a great place to start and the immediate Vast. Also contains a very beautiful and detailed map of the city. I loved it.
