Princess Mi Amore Cadenza had always been happy when she was a student at Canterlot Academy, being a Foal-sitter to Twilight Sparkle, and going to be marrying Shining Armor soon. There's just one thing that is missing from her whole life; her little brother named Norvail Winder. Last time she spoke to him while she is foal-sitting Twilight, he said that he needed some time alone, talking about some things and learning about the real truth.

After 10 long years of traveling, Norvail has returned home from the human world. Only this time, he isn't in a happy mood when trouble has surfaced and now everything is really going out of control in his life. Now every pony including his sister is in danger and nothing will make him leave his home again if things need to call in for drastic measures.
