Iron Kingdoms, the setting for the tabletop game WARMACHINE, has an interesting campaign called the Witchfire Trilogy.  If you are interested, the main campaign book is in the game store for you to peruse along with helpful information on character creation.

There is some good background information about the setting on their site.  Note that this is a 3.5 setting - not 4th edition.  

If you have questions, you can send me an email, leave me a note in the store, or heck, even come visit in person (I'm usually there Tuesday nights)

(I also posted this in the D&D section)
