Without having run it, but looked through it and considered it...
It comes with some nice maps, a little history of the area and a nice layout for the main feature being a dungeon.
Now I can't comment on the storyline (I have not read that part yet) but it appears that it should be easy to integrate into most settings.
I'm sure someone else here can voice what they think of the storyline...
But overall I think it will be quite useful for my game purposes, I like to have a few other campaign options around as needed.
