Four Cardinal Virtues/Talk

I thought there were Seven Cardinal Virtues. Where did this list come from?

There are Four Cardinal Virtues, just as there are Four Cardinal Directions. There are Three Theological Virtues, as well. Their power combined forms: The Seven Saving Graces, or something along those lines, and please don't quote me on that name as I just made it up.

I can't tell you how I know all this. It's a government secret.
