Moonshine is Rainbow Dash’s grandfather from her father’s side. Ever since he was a little colt, he was a serious worker, a strong force and a inteligent leader. It was his destiny since birth to become a royal guard in Canterlot, having to leave Cloudsdale. One day, however, he was having another normal day at his job, when he had to release a prisioner. He was surprised to see a elegant mare behind the jail cells. She said she had done nothing wrong, she was only there in place of her sister. They fell in love on the same day and soon had triplets: Rainbow Blaze, Rainbow Storm and Rainbow Sky.
