Sunset Shimmer is no spring chicken, that much is for sure. Her best days are a long, long way behind her. Content to live in the human world without settling into any sordid romances, she set her scientific mind to good use, and pursued a career that left the world in a better state than it was when she first arrived. A lifetime ago. But nobody, not even an equine-turned-human, is immune to the passage of time. And as an elderly Sunset settles down to enjoy a quiet evening on the porch of her small cottage, an old friend pays one last visit.
