GENERATE A PETTY EMPEROR
You can obviously cut off bits of the name, not all the rulers have such long and messy tittles. They are characterised by a ludicrous level of pomposity and one-upmanship, brought on by generations of succession wars over an Empire that none of them really even remember that well. They are not the entirety of the left overs from the empire, but they are the ones who can't let go. War, deserts, plains, cities, successor states, squabbling over scraps.
And to pad this post, more of my reference pictures from The Empires.
