Not sure press-ganging players and chaining them to the dice is going to work as a friendly recruiting tactic. On the other hand, it could get you players more quickly than the standard methods. 

Does a sock of dice count as an offensive weapon?

I could probably use it as a sap, but I'm not proficient.

My PC dice live in a sock; in fact, they live in whatever happens to be my most comfortable sock at any given time.  It's horribly unscientific, even superstitious of me, but it's also tradition by this point, and I am generally the sort to respect tradition, absent compelling reasons to do otherwise.

When someone spots me with a DF book and askes what it's about, I usually say something along the lines of "Imagine Harry Potter grew up rough, and found himself in a 1930's hardboiled detective novel, which then grew up rough, and found itself in modern Chicago."

Not the greatest pitch for a game, perhaps, but it usually works well for the books, so if I had to give it a stab, I'd start there.

My first choice would be a fairly low-power Sidhe of some sort.  Magical chops, but not the sort to take on a Dresden one-on-one without some serious prep.

Mostly because I think it would be really, insanely fun to play around with 1) not being able to "lie" but constantly bending the truth, and warping perspectives via glamor, 2) constantly, compulsively  maneuvering to get people in one's debt regardless of any actual malice, 3) dealing with cashing in on those debts to make up for not being a powerhouse, and 4) being forced to pay off a few of my own, much to the chagrin of the party.

Plus, hey, isn't Melkarion a pretty decent name for a Fae Knight?
