The product is amazing! Not only does it reveal one of the most influential aspects of the game setting (if indirect ones in most games), it also provides much needed crunch to help round out characters - and in ways the consumer base have been clamoring for! But above all, just for the setting and fluff, Luna is the best of the set. I couldn't have imagined a Luna this awesome. Good production quality, good writing, good demonstration of responsiveness to the market - this book means business.
