Luna finds herself on a train to Trottingham. She is on her way to find some pony she hadn't seen for years now. Her daughter, named Shadow Saber, whom she birthed in the first year after her release from the moon. For her sister's sake Celestia suggested to let Shadow be raised by a surrogate. Now, nearly 16 years later she has come to bring her daughter home. But reuniting a teenager to a parent she's never know might be more difficult than it seems.
