The Wasteland: a place where all that is good and pure dies. Men may hold to ideals they find good, yet they can rarely ever meet them. Democracy, freedom, safety, all are just words to be thrown around by corrupt bureaucrats wanting to secure more power. A place where the hero is the villain, and the madmen are the heroes.
Equestria: the land of plenty, where ponies can go their entire lives without a single issue or problem. Where the good are told they thrive, and where ponies are told no evil survives. Freedom, safety, harmony, the ideals everything is supposed to meet. The heroes have time to throw parties, and the villains are never heard from.
Yet all it takes is one man to save both the realms. One man to cleanse the Wasteland, and one man to reveal the truth to the Equestrians.
