Created by Nine the Phantom during the Dark War, grimoire are used to control Ars Magus by using the seithr around the air. They are controlled by the NOL, who create them, manage them, and regulate them, leading to what some call a monopoly and leading to their nickname of the "Library". Not all grimoire were created by the NOL or Nine, as some existed up to 50 years before the Dark War even began.
Grimoire do not necessarily take the shape of a book, and can be found in the shapes of various different objects, such as a mirror or scales. More advanced versions of grimoire do exist, such as the Ars Armegis and Nox Nyctores, and depending on the degree on which a grimoire is smelted, they can be assigned different ranks and power. A grimoire and a person can fuse to become one and this is known as a Remix Heart. They are exceptionally rare and only one has been known to exist. At some point, various grimoire went missing in the 15th Hierarchical City of Torifune and various ones were rediscovered by Team Remix Heart.
In the XBlaze possibility, a Grimoire is more an ability, not an object. Anyone with this ability is capable of using the XBlaze technique, an ability that stores seithr for later use. Three exist in the XBlaze possibility, one of which was replicated and exists in the BlazBlue possibility.
