Buttercream Cake was born into an ordinary family from Manehatten. She had a beautiful brown mane, a pale yellow horn, and…wings. Even at her birth everyone around her was telling her to choose a different path. One day, she is asked in for an audience with the princess, who tells her she will send her to Ponyville so she may follow her own heart, but in exchange, she must visit the librarian there once a week. Little does she know that she will be making the biggest decisions of her life and finding out what her duty is.
