I just started watching a few eps of this show, and it's pretty cute and fun to watch. I am curious about a few things however. These things would probably be answered if I watched the whole show, but I'd like to know now and I wouldn't want to take time to watch the whole thing right now.
Why exactly is Twilight Princess Celestia's apprentice anyway? Is her backstory explained eventually, or is that still unknown?
Will we be seeing any human characters in the show? To my knowledge, some of the other MLP cartoons had human characters, so why not this one?
