From the publisher's site: This is our flagship product as Moon Design Publications launches the 3rd Age of Glorantha. The huge success of our Kickstarter forced us to break it into two hardcover books. And when you get it, you get both books. It details all the major places in Glorantha, all the cultures. That’s everything you need to run a campaign in any part of the world! This the sister product to the Argan Argar Atlas. You will want both. The Guide to Glorantha is coming as soon as our Mostali craftsmen can complete it.
