Thanks for the kind words, Neo!
I, too, don't wish to step on NDAs, but I do wish to correct any false impressions...the GG is, basically, the ultimate guide to the B5 universe. It details LOTS of worlds, including many only mentioned briefly in canon or some which were just names on a map. It also tells you everything you might want to know about traveling in the universe, from the luxuries available on a Centauri cruiser to what happens when the Minbari catch you smuggling.
At the risk of going into advertising mode...if your B5 campaign ever takes you off the floorplates of the station itself, you will want this book.
Please forgive the lack of humility, but I think this is the best work I've done in the B5 line, and I hope the readers do, too.
