World Void Information Control Organization

The World Void Information Regulation Organization (世界虚空情報統制機構), called for short the Regulation Organization (統制機構), or the Library (図書館) by their detractors, is a multinational task force, run by a central authoritarian leadership in the world of BlazBlue. The Librarium's purpose is to keep balance in the world by safeguarding and regulating sources of dangerous power. The organization can be compared to the police or the military.

Information
The World Void Information Regulation Organization was created during the Great Dark War by Yūki Terumi and by Seven of the Ten Sages. Back to that time it was known as the Void Information Administration Bureau (虚空情報管理局) and was consisted of the leaders and representatives from countries all over the world. After the war, the organization moved to the Magic City Ishana and merged with the Magic Association, becoming the Void Information Management Agency (虚空情報管理機関).

The planet is covered with Magic Element which in high amounts is deadly, so the mankind began to die out because of this. The organization took control over the people and built Hierarchical Cities, which are high-altitude areas. After the Six Heroes disappeared, Ishana was forgotten, and only the Twelve Originators maintained their strength, they decided to keep the grimoires and control who should have access to them. Decades later, the organization has become what it is today, the World Void Information Regulation Organization.

The organization is ruled by the Imperator. Information on the supreme ruler's location is kept strictly confidential, even within the Librarium. The Imperator rarely appears in public, and only a few people know what the Imperator looks like.

The Integrated Headquarters (統合本部) are located in the 1st Hierarchical City of Ōkoto, and orders are issued from there to other city branches. However, sometimes orders are dispatched directly by the Imperator by Decree From the Emperor (帝からの命令書).

Although the organization claims they keep the grimoires from being misused, the people resented them for their tight control over the only thing that could let them use the Ars Magus. A great deal of dissent was caused by this widening socioeconomic gap between those who could, and could not, use Ars Magus. Years later, this dissent would eventually spark the Ikaruga Civil War, when the Ikaruga Federation openly rebelled against the Librarium. After the war, the Librarium imposed a harsher rule on the world, punishing any sign of rebellion with the death penalty.

During the Ikaruga Civil War, the Imperator, Tenjō Amanohokosaka, was slain by Jin Kisaragi. Her rightful successor was her child, Homura Amanohokosaka. However, Hazama and Relius Clover did everything to put Hades: Izanami in the Imperator's place. The real successor the most probably would be killed, but Kagura Mutsuki had Homura under his protection, as per Tenjō's request. Eventually, Homura became the Imperator, as it should be before.

Divisions

 * Zeroth Division: Wings of Judgment (第零師団・審判の羽根) is not officially the part of the World Void Information Regulation Organization military forces. Technically they are called "Judges", or begrudgingly Garbage Disposal Squad (ゴミ処理部隊). They are tasked with punishing those who rebel against the Librarium, be it civilians or actual members. Their judgment is based on strict standards set by the Imperator. They wear white uniforms, and their theme color is "incorruptible pure white". Members of this squadron wear white uniforms, special robes 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.
 * Third Magic Division (第三魔道師団)
 * Fourth Magic Division (第四魔道師団)
 * Imperial Guards (近衛師団) are elite members of various divisions who are sometimes called to assemble as a single group by the Imperator, normally they go about their assigned duties within their division. As opposed to the Wings of Judgment, they usually do not travel in units, the only exception would be when the Imperator summons them. They are almost regarded as class or title itself.
