My wife bought me the Dungeons & Dragons 4e Player's Handbook for my birthday, and we've been talking about playing it. She has experience with video games: we've always played video games, and even met on one. She also has some experience with RPGs: she has a level 85 on World of Warcraft, so she gets the basics, and a few months ago we ran through a Tolkein-based solo RPG, which was a lot of fun.
However, for the most part, my wife is apprehensive about playing D&D due to the violence involved. We reached an agreement that she'll play if we can find a campaign wherein her character can be a princess at a ball.
My first thought was "is the ball being attacked by goblins or something?" and then it occurs to me that there is of course much much more to D&D than just killing goblins. But, as I search for campaigns, I am finding great difficulty finding anything based more on politics and princesses than "Let's go take out a dungeon!" - low or high level. I'd like to avoid making one myself if possible.
So: Where can I find a couple of adventures that let the players be gentlefolk at a ball? Are there any campaigns about political intrigue anyone's run successfully? She's willing to do some combat-oriented dungeon crawls as well (for in-character and out-of-character experience) if it has a higher level adventure, but we're looking primarily for this.
(Update: Our game plan is to convert the challenges from our Tolkein RPG into D&D encounters - it will be close enough. After that, we'll go through the Brother Ptolemy and the Hidden Kingdom adventure suggested by @GPierce, and possibly go on to create our own adventures.)
