Just brilliant. Had so much useful stuff in it. I only bought it for the stuff on evil nodes, but found great ideas on temples and their effects, side quests, character notes, etc etc. Definitely going to pillage this time and again.

I gave this book an average rating because it did not meet my requirements, nor did it meet the claims on the back cover (or the sales blurb on this site).

Don't get me wrong. This is an excellent product. It is well put together, and the topics in the book are complete as presented. The artwork is very nice.

The races, feats, and spells are pretty well done and accomplish their most important objective--adding flavor to the bad guys. There are a number of NPCs and organizations covered in detail.

Unfortunately, I had purchased Lords of Darkness a few years ago and I liked the guidance it gave on creating an organization. I purchased this book almost exclusively because it stated quite plainly: "Within these pages, you will discover everything players and Dungeon Masters need to create the most evil organizations..." I expected to see an expansion on the guidance from Lords of Darkness covering how to develop original organizations. The topic is not covered anywhere in the book. (The organizations provided are great examples, but a chapter detailing how to develop the organization itself was what I was after).

I am not unhappy with the quality of the material. I am disappointed that I will get only limited use from this book.
