Supernova Shadow, a friend that the princesses missed with pain and sorrow, she returned, along with new threats and mysteries, just as thousands of years ago she will suffer the prejudices of her mental nature and connection to evil and black magic. Can she find a place among the ponies? Can she learn about the magic of friendship? Or, does she not need it? Can the world see that "Darkness does not turn you into a monster as long as it is not in your heart"?
