Twilight learns a new spell from a book she found in the castle library. Excited to show her friends, she invites them over to try it out. But everything changes completely when Twilight finds out she did the spell all wrong, and none of the ponies were who they used to be. The six friends have to enlist in the help of a pony Princess Celestia entrusted to them, from a land they've never heard of, to set everything back on track.
PS: I added a Slice of Life tag to this story, but I wasn't sure. U guys can tell me whether or not it is. Many thanks to my friend StarDancer1123 for making this amazing cover art! It's really cool!! 
Chapters (2)

7418619 Well, I'm not an expert nor do I know how your story is going to play out, so all I can tell you is that you need to stand out. What makes this mistake any different or more severe than the dozens of mistakes Twilight has made on the show or the thousands others have written fanfics about? What makes your story unique?
Love thus story so far!!
