Kingdom of Aincrad

 is the name given to the floors of new ALO's Aincrad which are in control of Hao, the Supreme King. It is his ultimate goal to conquer all of it and became the King of Aincrad.

Background
Hao had a similar objective in SAO: to force all players who still lived to join a single guild, defeat the GM and clear the remaining floors of Aincrad. For this, he joined the Guardians of Darkness, and first got rid of his guild leader Kamui, taking the leader status for himself. Later, he tried to control the glitch Skeith, and as result, gained his Unique Skill, Supreme Weapon. However, his ambition was stopped by the conjoint action of two guilds, Pendragon Court and the Army of the King. Hao himself was defeated by Ishi, but his life was spared. Hao was afterwards sent to the 's prison in the first floor.

Overview
In ALO, Hao's has a similar ideal: to create a kingdom of peace of prosperity, and make sure no other tragedy like SAO happens again. To accomplish this, he created his new guild, The Supreme Legion, with the objective of winning the Great Aincrad War, so that he can become the King of Aincrad and a Game Master. Hao's skill at battle made many players join his guild, but their methods were quite extreme: slavery, public executions of enemies and destruction of many other minor guilds and race armies to remove them from the conflict. Also, behind the shadows, Hao's cousin, Mordread and his guild, the The League of Darkness Knights also fought at his side. All them, VRSMA] players, capable of killing players both in game and in real life.

Opposing Hao, the Black Swordsman, Kirito, accompanied by his friends, many of which are former SAO players, formed a guild to defeat Hao and his Legions, called the Knights of the Blood (KoB) (named after the most important clearing guild in SAO). Many of the Nine Races of ALO supported them. While at first they were a small guild, they were treated by many Generals of the Legions as a nuisance. Facing small armies, with help of players like Galant and many other players who despised the Legions are some of the reasons why the guild quickly raised to become a very strong guild.

Once the Legion's clearers (lead by general Zar) reached floor 94th, they were forced to retreat, leaving KoB as the leading guild during the GAW. However, Hao decided to take the matter into his own hands. With an army of 10,000 legionnaires, that outnumbers the Blood Knights, he advanced to the upper levels.

Currently, the Kingdom spreads from the 1st floor to the 90th floor. KoB is the only guild which can present a challenge for Hao's Legions.
