After finishing her flight test, Rainbow Dash wakes up in a strange room with no recollection of how she got there. When the door opens, a mysterious pegasus shows her around a place called the Rainbow Factory- and changes young Dash's life forever.

Rainbow Factory was originally written by Aurora Dawn.

I do not own Rainbow Dash, Rainbow Factory or My Little Pony.
I do own Lightning Blitz and Cyan Zap (they're my OCs)
