This is during the episode A Royal Problem and this is starlight glimmer’s(you) dream. Celestia has Luna’s magic and is trying to stop Daybreaker and nightmare moon from fighting. (You are starlight glimmer and starlight glimmer only!)

Hey, this is my first talkie, so it might be a little rough. You can be a custom pony or be a character from the show from before season five. Enjoy!
