The population density of this city is at least 100,000 people per square kilometer. That's just insane.
Unsurprisingly, the Capital of the Sasamil Empire also carried the same name as the Imperial Family, Sasamil City. This was the biggest city in the Empire, with over one hundred million inhabitants. Without a doubt, a gigantic metropolis that expanded for over 1000 kilometers. Still, the entire city was surrounded by an enormous wall.
