This is the flag of the Martian Empire as seen in my story "When Aliens Invade!". The big red circle represents Mars (obviously), while the smaller brown ones represent Phobos and Deimos. The Sun is in the background against a blue-tinted rendition of space.

One day, I might write a little about the Martians themselves, but I'm not sure if that's acceptable for a site devoted to Minecraft.

Comments and diamonds are appreciated! :)
