So what exactly is Princess Cadance the princess of? We have Princess Celestia who's the Princess of the Sun, Princess Luna who's the Princess of the Moon, Princess Twilight Sparkle who's Princess of the Stars(?), so is Princess Cadance the Princess of Crystal? Does that make her the Princess of the Earth or do crystals have some kind of underlying property that I'm not seeing that makes her position so important?

I guess being in charge of the Crystal Heart is important because it leads to happiness all across Equestria but Ponies were already happy prior to that happening. So does that make Princess Cadance the Princess of Happiness?
