I am a ultimate fan of the Grand Duchy. Gimme, gimme!
Seriously, I think that would be absolutely great for new DMs. I remember getting the Gazetteer of the Grand Duchy when I was starting DMing. It was really great for inspiration and was written in a very clear and yet flavorful voice! The place too allowed for dungeon crawls, political intrigue or nearly anything you could come up with really. Awesome.
