After discovering a piece of the Nightmare's corruption residing within everypony, Princess Celestia and Princess Luna conducted an experiment to extract that magic. Their efforts were a success on Twilight Sparkle and her friends, but at a heavy cost. Instead of inanimate objects like the armor from Nightmare Moon, the most negative traits of the bearers were ponyfied. These manifestations of the Nightmare couldn't reside in Equestria nor could they be destroyed or banished. The act would also affect the true bearers. So they called upon a curious stallion to watch over them and guide them to true happiness in a distant, foreign city. Years later, the situation had worsened rather than improved. These are the chronicles of their caretaker; in a place that he referred to as 'the last casino.'
A/N: Trust me, this summary does not do the story any justice properly. I promise that you'll find an intriguing plot and better 'summary' if you read the prologue. I guarantee it.
Also, guru is my hero once again for the cover image and his encouragement on getting me to write this. You can find his art here: http://thegamefilmguruman.deviantart.com/
