Twilight Sparkle, Ruler of Equestria, receives a letter from a friend she desperately hoped would forgive her. But what she hoped would be forgiveness is instead a goodbye.
Twilight has lost all, but one of her friends, all but one. The one that was with her since before the beginning and stayed her truest and most loyal friend well past the end. Yet not even dragons are immortal.
Equestria has existed for a very long time, and the next order of business set in motion by Celestia and Luna is going to reshape Twilight's world. Quite literally.
