Even if you have minimal to zero interest in the Deceived as antagonists or player characters this book is worth purchasing. It contains a huge amount of delicious, well written setting material about the Mummy: the Curse setting in general, and about the Shan'iatu and the Nameless Empire in particular.
It also contains numerous powers that are usable by any mummy, and an excellent continuation to the pre-made adventure from Guildhalls of the Deathless.
The art quality is some of the best I've ever seen from a White Wolf/Onyx Path product, and for RPG artwork in general.
[5 of 5 Stars!]
