Civil war broke out on Homeworld several thousand years ago; rebel Gems known as the Crystal Gems fought against Homeworld's genocidal ideals. Homeworld lost a number of promising colonies to those rebels. Now, some of the surviving Crystal Gems just want to live out the rest of their lives, seeing and enjoying what they saved in peace. But when one of those former colonies is Equestria, with all its crazy magic, that life will be anything but peaceful. Luckily, the Gems left behind aren't exactly ones for sitting on their butts watching some show about technicolor ponies.
