This is the story of Trixie Lulamoon - a talented blue pony who has been utterly broken by tragedy. She is doing her best to save the world from an invading army of darkness, but it's not going very well. Equestria has refused to forgive her for her role in the death of Twilight Sparkle, and wants her to die. The surviving members of the Mane 6 are cold and bitter, and healing their spirits is not going to be easy. In fact, it may take a great deal more than a wounded Trixie has to give.
But the fate of everypony really does depend on her. Like it or not, Trixie is the new Element of Magic, and she is the only one who can defeat the Necromancer and his army of undead spectrals. If she can't find a way to restore harmony to Equestria, the dead will rule the living - and the night will last forever.
