A revolution is coming to Ponyville, which will spread to all of Equestria. Her name is Sapphire May, a young mare mechanic and engineer. She doesn't know it yet, but what she stumbles across with change everything for the better, and in some pony's opinion, for the worse.

NB: Sapphire May is a fan made character, and I have been made aware that there is another pony named "Sapphire" already. These two ponies are different characters.
