GLaDOS, the one powerful AI that ran the Aperture Science Enrichment Center, has been turned into a young Equestrian after being tossed in a realm where true science is unheard of and Magic is the primary factor in the advancement of civilization. As she matures, she'll experience normal everyday occurrences like saving the world from invading xenos, preventing a disastrous outbreak, over-throwing the current ruler of the throne, and other various things. No biggie, right?

So who is ready to do some science? And make 60 bits? Cash.

My name is Simon "Ghost" Riley. I was part of Task Force 141, an elite group of soldiers composed of the best of the best. Our mission was to take down Makarov, the mastermind of Russian invasion of America. The team consistered of myself, Roach, Ozone, and Scarecrow with sniper support from Archer and Toad. We didn't find Makarov, but we did find a jackpot of information. On our way to the landing zone, Ozone and Scarecrow were killed by mortar fire while me and Roach managed to survive. I dragged him all the way to the LZ but fate had other plans in store for us, specifically death at the hands of our own commanding officer. Shot point-blank, the shock and blood loss made my vision blur as everything went dark. I couldn't feel my body or when I hit the ground, but I could smell the scent of something before flames engulfed the world. I tried to resist Death's offer, but in the end, I gave in. I welcomed his embrace, hoping that I'd finally find peace.

Instead, here I am, alive and kicking in a world full of bloody ponies.

Not so long ago, Equestria barely defeated two almost unstoppable creatures known as humans, which they called the Second and the First. Almost five years later, another one has shown up. The military takes up arms, the princesses are stricken with fear, and the Elements of Harmony assemble, ready for battle. But 'the Third' has no idea what's going on, and only wants to know how he came to be here, and how to get back home. Good questions indeed...But will he ever get his answers? Or will his predecessors' legacy catch up to him first?
