Wow!... that is the first word that comes to mind as I read through this guide for the first time. First of all, to see new products for my most beloved of all Campaign Settings was almost more than I could stand but then to see the absolutely gorgeous layout my jaw continued its drop to the floor. The guide is truly for the players meaning that it gives nothing away as to the dirty secrets of Kulthea that could potentially spoil it for the players. It gives information on the Heavens, the Essaence (the flow of magic that permeates the world), Geography, Gods and Religion, Races, History, Powers of Note, and finally Languages.
It gives enough information to be informative but also (hopefully) leaves the players intrigued and hungry for more. It is well paced, well written as we've come to expect from T.K. Amthor, and fresh. The fresh aspect is particularly amazing to me simply because this campaign setting has been around since roughly 1989 and I have been a collector of every product from that date onward. And to see something new that feels fresh is a true testament to the writing skills of the author.
Finally, I cannot say enough about the layout. The illustrations are absolutely lavish and of the utmost quality. The presentation is hugely above average and very visual making it a joy to just peruse.
If it sounds like I'm gushing, well, I'm guilty as charged. You simply will not be disappointed with this product.
