Idea for a 3rd series of Empires
Although I know it's highly unlikely, I was recently rewatching season 1 and had this idea. It would be really cool if all the creators return to their empires (As different characters with no memory of what happened) centuries after the destruction of the empires. They discover the ruins, attempt to restart civilisation and try to figure out what happened to destroy this place (But all their theories are extremely different to what we know actually happened).
