A few years after Luna's return it seems that Equestria will finally know an era of peace and appears to be on the verge of a new renaissance. Ponies are happy. Luna is recovering. Celestia is miserable.
With his dark past heavy on his mind, Sombra is put to the test as he begins a reformation process. Though his mind is no longer crowded with the influence of dark magic, his heart is none the lighter. Let the test begin.
In an Equestria where Celestia and Luna have slain each other, a human is brought to Equestria in the body of King Sombra, in hopes that he might be able to save the kingdom from the fiends of Tartarus...
A human soul is stuffed into King Sombra's body. Having no idea what's going on, and thinking he is in some kind of coma, he just casually strolls into the Crystal Empire.
The time of darkness is nearly upon Equestria. A powerful demon has his pieces in place. The only thing that stands between him and domination is a band of unlikely ponies, lead by an unexpected hero, who must face his own demons.
