It's been said in prophecies that nopony will know the time or date the magic of Equestria that empowers its citizens would leave. I thought it was just superstitious nonsense written by ancient witch doctors. In a sense, they were right. But I would have never expected it to come like this. —Princess Twilight Sparkle, 05/05/1268

AU tag added due to the Cutie Mark Crusaders getting Cutie Marked.

Celestia knew this day would come. He would return and have revenge. And all she could do was think back to the old times. She loved him, but when she broke his heart, she never knew he would become a monster. This is the story of a love that could never be, a hateful villain tucked in the shadows, setting her plans in motion, and a kingdom that watched in horror as everything plunged into chaos. [New Alt. U Tag] [COMPLETE!!!]

Twilight accidentally steps on a snail. This makes her sad. As the years go on, several other things happen.

I thought this was my first story rated 'everyone', but it isn't. It kind of is though? Anyway.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.
