This is a brilliant idea for a camaign setting book. Instead of releasing one socking huge book worth a fortune, it is being released in the form of a monthly digest. Each issue includes details on one hex of the regional map. Most issues also include an article on one of the kingdoms in the setting, and part of the "Encyclopedia Arcana".
Dislikes: spelling and grammar continue to be an issue with this series of products. (Manner house? Really?)
Also of note: Say you want to adventure in the Kingdom of Mulithor. You would need the journals that cover hexes 2, 9, and 10. (Not a complaint, but it is something you should be aware of.)
