Presenting… your Princesses of the Sun and Moon, Celestia and Luna! Your princess of the Crystal Empire, Cadence! And your recently appointed Princess of Friendship, Twilight Sparkle! Your four princesses of Equestria, everypony!  
Now that they’re all here, I decided to bring them all together for one royal group photo. And yes, they’re arranged differently to how they were introduced and announced, but I think it worked best this way. I wanted the two groups of sisters side-by-side and also thought Twilight should stand in between Celestia and Cadence.
