Do I need to read My Little Phantom, Friendship is Ghostly in order to understand this story?
Not really. You can if you want to though.
You might want to make a prequel so people know what happened in the 3 season's you skipped over
Actually, In the description there is a link to the prequel. Only the first season is up. I got permission to do this from another author.
