From the back of the book:
The book you are holding contains everything a Realm Controller needs to become part of the quickly growing Multiverse. This is the knowledge you need to run your own realm!

You set them down on the realm and guide them through life's journey. Every now and then, throw them a challenge like a flood or earthquake, political dissension in the government, a failing economy, or even an attack from a nearby town. Then share in their excitement as they overcome the odds and triumph.
This book includes all statistical charts and information to run the ROTU Gaming System. It also includes a decades worth of knowledge from Realm Controllers across the country. Their helpful hints alone will save you valuable time and help you run the best realm possible.
