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 Karnassus City-State Alliance, usually referred to as simply the "City-State Alliance" is a union of multiple races and cities. 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. Each city, including the other territories, hold on average a population of 400,000, with the largest city having 600,000 people.

The City-States's national hero is the Dark Knight and the Brave is also known to have been originated from here in this alliance.

Origins
If one were to rewind time back a few centuries, there was once huge nation that was the origin of the City-State Alliance. Following that country’s collapse, fourteen city-states popped up, each with a metropolis at its center. After that happened, there was much bloodshed between the city-states or rather, small countries.

In a way, these newly independent small countries were not on good terms with each other. As a matter of fact, they were in a state of near constant war against one another, with the states uniting and splitting ad nauseam. This continued on for who knows how long until an event now known as the Great Debate, at which the current alliance between the twelve city-states were formed.

City-State Tournament
Despite the unification of the City-States, it is still difficult for the multi-racial inhabitants to abandon their prejudices towards each other. While the days of conflict between the states is already distant history to shorter-lived races, to those with longer lifespans it is still recent memory to them.

For this reason, to create an outlet for these past grudges, a tournament between the states is held every five years. Great importance is placed on this tournament being properly prepared, especially following an accident where there was a riot after one city failed to include one of the tourney's traditional events. While there are sixteen events, the most popular is the Connelier — or mock combat.

Equestrian King
At some point, the City-State Alliance made a powerful enemy in the form of the mysterious Equestrian King, who would periodically attack the nation. Unfortunately, the nation's military might is independent to each city, forcing weaker cities to resort to drafting levies just to fend him off.

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 Mithril 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 to.

Currently the next upcoming tournament in the City-State is schedule to happen in four years at the city of Bebad. In addition the City-State Alliance is facing an ongoing attacks from the Equestrian King. However the Mayor of Bebad, Ri Kista Kabelia, though in the middle of preparing for the tournament, is concerned about the rumors of the Sorcerer Kingdom. She requested help from her grandfather, Ri Berun Kabelia to use his connections to gather more concrete intel.

On another note, it was said that Ramposa wanted both his son Zanac and his daughter Renner to seek refuge in the City-State Alliance as the Re-Estize Kingdom’s representatives. However, in the end, neither the two of them chose to flee their nation, deciding to stay behind like what their father is doing.

Culture
It was said that humans were the minority in the City State Alliance. Nonetheless, it's unclear how they will fair with the the number of other races who are living in the nation as well since they too like the humans, don't have a majority of their kind either.

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

Currently due to the geological distance to and from the lands of the Sorcerer Kingdom and the city states, there are a variety of different rumors surrounding the Sorcerer Kingdom that may or may not be true, resulting in a mix of various opinions on the new nation by the Alliance leaders.

Re-Estize Kingdom
Prior to its downfall, its been implied that the City-State Alliance and the Re-Estize Kingdom possessed a good diplomatic relationship with each other. As seen where Ramposa III attempted to convince his second son and his youngest daughter to flee to the City-State Alliance upon the Sorcerer Kingdom's deceleration of war. He wanted his children to seek refuge with the alliance and survive by going into exile. This in turn hinted that the higher ups of the City-State Alliance were more than willing to provide refuge to the Re-Estize Royal family if requested.
