I am starting to read the fluff for Fantasy now that the End Times books are out. I have the Nagaash and Glottkin rule books, but I havenít started the fluff books (Canít remember if they are the Book I or Book II in the sets) that came with them yet because I didnít know if there were books that I should read first? Also I see that there are also actual books for these as well, are those just the same as the fluff book that came with the rules or is it something else that I need to get as well?
