"Dispatched in mankind's darkest hour, we are knights of the blue flame!"
The Novus Orbis Librarium (
The NOL's current Imperator Librarius is Homura Amanohokosaka.
In the aftermath of Dark War, the NOL was created when the Mage's Guild merged with the the Orbis Librarius Norma. It was created to regulate the various grimoires, Ars Magus, Ars Armegis, and Nox Nyctores which were created during the era. It merged with the Magic Guild, with the leading houses of the 0th Magical City of Ishana becoming the Duodecim. Over time, one part of the organization split off and became Sector Seven. A lot of grimoires were created at this time by the NOL. The NOL began to rebuild the world, and created the Hierarchical Cities that populate the Earth's mountaintops - on top of every city is the Librarium's branch, and at the bottom of the branch lies a cauldron. The entirety of the 15th Hierarchical City of Torifune is the NOL's Military Academy, and is used to educate those who wish to join their ranks.
Not only does the NOL regulate Ars Magus grimoire, but they also manage the storage and creation of it, creating a monopoly on the devices. Generally speaking, the NOL manages information that concerns the Boundary, but they also act as a world-police force, apprehending criminals and issuing bounties for vigilantes. Because of their regulations over grimoires, civilians began to resent the NOL as they stand between them and the access of Ars Magus. Despite this, the NOL exists to safeguard the tremendous power that the grimoires hold, preventing the misuse of them. 
Nearly all of the NOL's orders are issued from its headquarters in the First Hierarchical City of Ookoto. These orders go to the various branches in the Hierarchical Cities, while specific commands are issued within a branch itself. In very rare instances, the Imperator may declare an Imperial Decree which is a command personally issued and signed by the Imperator.

The standard male NOL uniform has a white inner jacket which is made of thick cloth, like that of a kimono. There are black parts around the torso of this jacket made of leather. Over this, most soldiers wear a tabard that is also made of the same cloth as the inner jacket, while the yellow colored borders are made of leather. Connected to this tabard are shoulder clothes, again made with thick cloth. The uniform has trousers, although this is optional if the soldier is wearing something like a full-body bodysuit underneath the uniform. There are also white leather gloves that reach up the forearm and leather boots with a silver lining. Variations of this uniform include red ties, which can either be clip-on or genuine.
The standard female NOL uniform has a backless and sleeveless tabard. The chest area is made of rubber, as is a band around the waist to make the uniform fit tight. The white parts on the back and front are made of a thick cloth material while the colored sides are made of leather. There are sleeves held onto the arms by metal cuffs, and white gloves made of cloth are also required. Tights are optional, and are made of black leather and soft rubber. A beret made of a finished material is also optional, and it has a thick silver band across it. Finally, the uniform's shoes are made of leather with silver linings. Unlike the male uniform, the red tie seem to not be optional, but can be clipped on.
The female uniform also has an optional coat as opposed to the tabard that male uniforms wear over their inner jacket. This coat is thick and covers the entire top half of the uniform. On it is golden embroidery, two sleeves, black belts and a hood.
NOL uniform largely differs between owners, as most of them are usually customized for their owner's comfort or practical usage. One example of this is Grimmwood's sleeveless shirt, the thermal suit Jin wears under his uniform, and the Sealed Weapon Izayoi which Tsubaki is permitted to wear on duty despite it not being part of the organization's dress code. The color of the uniform depends on the branch of which the soldier belongs to - there is the Shimmering Blue Flame for the Ars Magi; the Triumphant Return of the Kingfisher green for the Air Corps; the Corrosive Jet Black for the Intelligence Department; and the Incorruptible Pure White for the Wings of Justice. Ars Magi have elastic red metal tails on their sleeve cuffs, the Intelligence Department have small golden ornaments on theirs, and the Wings of Justice have white feathers instead.
BlazBlue: Central Fiction Library Entry
- Novus Orbis Librarium
Also known as the ‘Librarium' or ‘NOL' for short. The organization that controls the present world. Jin and Noel used to be among its members.
They are also simply called the ‘Library' due to the large number of Grimoires they possess. Their rule is mainly based around controlling Ars Magus, administering the Hierarchical Cities, and training the Praetorian Guard.

The decision-making body of the Librarium. It is located in the 1st Hierarchical City, ‘Ookoto.' It issues orders to the various branches of the Librarium. 
Zero Squadron: Wings of Justice
A military unit Tsubaki belongs to, consisting of Imperial Guards, as well as Praetorian Guards who are Imperial Guard candidates. Their uniform theme is an 'incorruptible pure white'.
All members wear the same cloaks and masks, making it impossible to distinguish features such as gender or facial expressions at a glance, and they are widely feared as a result. Their main task is to eliminate rebels and traitors of the Librarium, thus they are begrudgingly called the 'Librarium's garbage disposal squad' by some. 
- Third Squadron
One of the military groups under the Librarium. An Armagus Unit. Warrant Officer Ellen Nelson is one of its members. 
- Fourth Squadron
One of the military groups under the Librarium. An Armagus Unit. Jin and Noel are among its members.

They mainly operate Ars Magus Vessels and smaller flight equipment called Shebalves, and specialize in combat from the skies. 
- Garbage Disposal Squad
A nickname for the 'Wings of Justice'. Since their main task is to eliminate rebels and traitors of the Librarium, they are often begrudgingly called this by other units.

- Police Station (Librarium)
A place where Librarium personnel are stationed, existing on every level. They secure and hold criminals.

Field Officer class: Colonel, Lieutenant Colonel, Major.
Company Officer class: Captain, First Lieutenant, Lieutenant, Warrant Officer. Master Sergeant, Sergeant, Corporal, Lance Corporal, Private First Class, Private E-2, Private E-1.
- Erroneously, Library Mode lists the Praetorian Guard as "Imperial Guards", while "Praetorian Guard" is used to describe the average NOL officer.
