This story is a sequel to Snowbound
It's a bad old time to be human. About half the world is gone thanks to Celestia's Barrier, the only options are 'fight and die' or 'get turned into newfoals,' and everything's falling apart. The greatest menace to America as they wait for the Barrier to touch down is not, paradoxically, PER, but restless Human Liberation Front terrorists that dream of taking control of the fight from the brave PHL. One of the worst HLF men is Viktor Marius Kraber, a traumatized Afrikaner, former father, and former surgeon with an appetite for destruction and big guns. But one day, wracked by guilt at an HLF checkpoint, he lets a lost filly and her mother live. From that point on, his life goes to hell (more than usual, anyway) as he tries to make his way and cast aside hatreds in a world gone mad, and maybe, just maybe, become a good person.
Forced to deal with irritating hallucinations, self-hatred, enemies on all sides, and developing a conscience in a world gone mad, will he manage to survive in this world? Will he ever become a good person? Will he join the PHL and befriend the freakishly huge earth pony stallion named Aegis seen in the cover image, and shoot Queen Celestia's spine out?! Can he? FOR THE LOVE OF GOD, CAN HE?!
Of course he can! It's a fokkin' prequel.
(Well, actually, considering the emphasis on the development of a character from before the beginning of a game and the fact that it takes place between stories, it's actually more of a presequel. Or presidequel?)
