Notes:

(Due to negative feedback, I made a newer better version) Me and my friends came up with the idea of an Invasion of Earth by the homeworld (I have a map of Europe in the gallery and an Asia map coming soon) What I think would happen is that the Homeworld would invade the poorer countries first, move from the south to the north. Humans who surrendered would either be killed, used for labor and experiments (since gems can grow their own troops) While Garnet and Amethyst help on the front lines, Pearl and Steven would supervise human troops and protect them from the Homeworld. You may ask "Why is this so different from our world?" Because SU has an alternate history, so things are similar, but a litte different. Such as Canada colonizing Alaska first.
