The Novus Orbis Librarium (also called "N.O.L." or "Library" for short) is an evil organization in Blazblue. After the First War of Magic, in which the Black Beast ravaged the world into a huge wasteland and was stopped by the Six Heroes, it becomes clear that the Nox Nyctores, weapons used against the Black Beast, became a threat to the world if it fell to the wrong hands, as the world has been already tethering to its destruction. Thus the organization was formed, with noble intentions of preventing the Nox Nyctores to fall to the wrong people and keeping order. Despite the dystopian and dictatorship nature of N.O.L's rule, it was accepted as the only alternative of the world aside of anarchy. In a way, N.O.L. clearly had the best interest of the world and enforced the necessary rule to keep the world and protect it.
Over time, however, N.O.L. became increasingly more drastic in implementing the rules, eventually being viewed as an tyrannical organization. The Ikaruga Federation, unable to stand such stance, initiated a massive civil war which became known as the Second War of Magic. N.O.L. managed to claim victory as its prodigal soldier Jin Kisaragi ended the war by assassinating the Federation leader Lord Tenjou. The Federation is eventually dissolved, and in response of this bloody civil war, N.O.L instated a much harsher rule that any kind of disobedience will be punished with instant execution.
It stands as the main opposition force of the BlazBlue series. However, the organization itself isn't all evil, as it also provides academies for children to learn in the Hierarchical city of Torifune. The main reason of its antagonistic stance is rumored that it was manipulated from the shadows by both Yuuki Terumi and Relius Clover. However it's reavel that Izanami the goddess of death and the master of Terumi and Relius usurped the title of Imperator from Tenjo and now his son Homura became the Imperator after Izanami requilished the title. Izanami also backstabs Terumi and Relius after they have no longer become useful to her cuasing the death of Terumi and Relius utter humiliation.
