Log Date: 822. My name is Peridot. I have come to earth to hollow it out, enslave all humans, and fuse gem shards together. My advice is to just die now, it would be better for all of us. Anyone wearing a trench coat will be spared. Watch out, when I get rid of the Crystal Gems . . . get your trench coats ready!
Or, if you prefer the protagonist-
My name is Amber. I work with a currently unnamed group to fix the mistakes that the Gem War left on Earth. Along with Pewter and Ambergris, on this team is Blue Fluorite. We also receive occasional help from the nomads Dendrites Plume, Diamond, and Adventrine. Our main enemies are Cuprite and Covellite, which you should not approach under any circumstances. They will fuse to make a dangerous and powerful gem named Charoite. If you see any of these gems, I urge you to contact me immediately, we'll take care of them. I rue the day I released them from their gems. Also, I have a pretty bad history with Pearl. So I'd prefer if you didn't mention her.
