Ten years have passed since the Second Lunar-Celestial War, and pony civilization has all but collapsed. In these dark times, tools of war have been developed to protect newly formed city-states that once were the cities of the united Equestria. A pegasus living in this post-war Equestria, Sprocket, is looking for a way to get revenge on a bandit who maimed him beyond repair, but cannot do it alone. For that, he will need the help of his friends.
