Princess Twilight Sparkle has lived in Ponyville for many years. While most of these years have been fun and adventurous for her and her friends, recent years have taken much away. The passing of Applejack, the last of her remaining friends, hurts her greatly. After the pain was starting to subside, a new greater problem comes to light. Twilight will do all she can to prepare for this coming problem, but a simple letter might not be enough to prevent the pain that will follow.
