The time of heroes is long over. Those who didn't get out of the game while they still could were taken out, finding themselves in prison or in a shallow grave. Anyone can put on a mask, but actually being a hero, Equestria learned, is easier said than done.

Evil didn't yield to the heroes even then. It adapted, raising its own masked champions to oppose the Vigilantes. But when the heroes left, the shadows stayed. Now, crime is out of control. No one dares to fight back. No one, that is, but one mare who takes up an old mantle to desperately try and hold back the darkness threatening to consume the city, and defend harmony.
