OK I've just seen the new trailer for the pony movie

And I've got some questions concerning the plot.

so spoilers ahed.

Where are the guards?

Where is Celestia?

I'm serious. when the movie starts with a letter from Celestia saying

"Dear SunsetTwilight Sprinkles Sporkle
My Sister and I decided to take our long overdue vacation to outofthestoryland taking discord and the guards. You're in charge, For the love of me DON'T BUCK THIS UP!

This are my two main questions I had after watching the trailer ...well I've got a few other things I like/disliked but those questions are like the first thing I asked myself after the trailer ended.
