Karsanas City-State Alliance

Karnassus City-State Alliance (カルサナス都市国家連合) is a nation located east of the Baharuth Empire.

Background
The City-States's national hero, the Black Knight, is known to have originated from there along with another warrior named Brave. It is also the base of operations to the infamous Ijaniya, an assassin organisation, led by the heiress of Ijaniya.

Humans do not appear to be in the majority that make up the whole population of the city states, however some cities were said to have at least half of their population consisting of humans.

The Invaders of the Large Tomb Arc
The Black Knight, a hero of the City-State Alliance, was mentioned by the gathered workers in Count Femel's courtyard.

The Ruler of Conspiracy Arc
According to Fluder Paradyne's intelligence on the countries, the City-State Alliance was some distance away from the Baharuth Empire eastward. However, upon consulting both Demiurge and Albedo, Ainz decided that intervening there was not wise.

After the Baharuth Empire's vassalization by the Sorcerer Kingdom, one of its Adamantite Adventurer Groups, Silver Thread Bird relocated to the City-State Alliance.

The Witch of the Falling Kingdom Arc
It has been established that the City-State Alliance has sent in spies within the nation to monitor it, although the higher ups of the Sorcerer Kingdom are already aware of their surveillance over them.

The City State Alliance is also one of the main destinations that the Mythril team Four Armaments considered to run away too after they dealt with the invading undead army as it was the closest best alternative destination to go too.

Culture
It was said that humans were the minority in the City State Alliance.

Politics
Given its name, the nation seems to be formed by a coalition of independent city-states.
