I felt readers here might like to see a post about the book from the offical Troll Lord site:
"Gamers should find that this book allows one to accomplish---effortlessly---what is often a fun but difficult (or at least time-consuming) aspect of DMing: World Building (facts), thinking of "things" to put into all kinds of rooms (library, lab, torture chamber, privy, etc), populating areas with appropriate flora and fauna, determining simple treasures while running "on-the-fly", etc. It can be used in preparation of a campaign, to help dream up surroundings for characters in a novel, or even as a quick reference during a game in answer to simple questions like, "what is the building's construction? How is it unique?"
The idea for the book started when I was writing (as yet unpublished) adventures for Gary's Lejendary Adventure series. After designing many buildings, dungeons, temples, cities and towns I thought to myself, "How the hell does Gary make every place so unique? How does come up with so much STUFF...everywhere!" My strength was character development, plot and such things, and although I am sufficient to the task of building encounter locations, I wanted a handy menu of "descriptors" to lend everything verisimilitude! Buildings, trees, clothing, geography, herbs, facts and charts, etc...after all, I had painstakingly researched every building I described in my adventures, so a book like this would have made my life easier.
...As Gary said, the book is not only a book of lists and facts. It is a book of descriptive elements and facts to support the basic elements of the Dungeon Masters world-building efforts.
