Royal families, right? In a future different from ours, royalty from all over the world is coming together for the biggest conference of the century to discuss major issues...but hey that's none of your business! You're just their kid that they've dragged along so you can get nice and socialized with the next generation of royals. So now all of you are in a small castle in the countryside far from any civilization but with all the fun you could ask for.
Have fun and don't get into too much trouble... ;)
