This story takes place in an alternate Human!Power-Ponies universe.

It's mid-winter in a Mirror!Maretropilos, and the superheroine Mane-iac is enjoying some well-deserved relaxation after the Holidays. With the Malice-Mares behind bars, things in the city have come to a happy peace.
But one night, when a mob war turns deadly, a new vigilante rises from the shadows to exact his punishing, savage justice. No criminal in Manehattan is safe from the wrath of the darkness, and now Mane-iac must plunge herself into the night to combat this new terror.
Can she put a stop to the violent, bloody reign of her new rival? Or will she become another victim in his path of rage?
