Power
Ever hear the quote "Money is power?" It's true. Sure, it's nice to have a magical scepter that can summon woodland creatures to your aid; but if you haven't got one of those, money is where it's at. If you pay someone enough, you can convince them to lick a frozen flagpole, even when they know their tongue's going to stick to it. If that isn't power, we don't know what is.
