The city of Adenberd was huge, like REALLY Huge! At least sixty thousand people lived there by rough estimation as there was no custom of counting the population in Akarxia. The reason being that it was an arduous task in the first place, and second that people died all the time in Akarxia, as the mortality rate was quite low.
No one in the entire Atrana Kingdom who had been to the city of Adenberd would argue that it was one of the most advanced, populated, prosperous, and largest cities in the Kingdom.
It was divided into a few layers as most of the cities were tended to in the Kingdom. The residential district where the rich lived, the commoner's neighborhood where all the ordinary or middle-class people lived, the bazaar, and the city square along with certain miscellaneous places.
