Set around one hundred years after the show My Little Pony: Friendship is Magic, Headspony follows the path of one Liberty Stoneheart as she is brought face to face with the horrible deeds of her country and her own blackened soul.

Can she put a life of Duty behind her, and forge a new path for both herself and the city she cares for so much?
Or will the Darkness consume her, and leave nothing left but a husk. As it has done with so very, very many ponies in this day and age…

This is a tale of Duty and Order, Law and Justice, Good… and Evil.
