So, the thing about gems is that they come from this place called the Gem Homeworld. It's ruled by the Diamond Authority, and they're... not so good. They colonize worlds and drain them of resources which... make it so no life can survive. They tried doing that to Earth, but my mom didn't want to. That's why she started the Crystal Gems. To fight Homeworld and save the Earth. But she might have done something bad to make it happen... She might have shattered a diamond. Pink Diamond.
