Grimoire

A Grimoire is a text-based book of magic typically filled with instructions on how to create magical objects like talismans and amulets, how to perform magical spells, charms and divination, and how to summon or invoke supernatural entities such as angels, spirits, deities, and demons.

In many cases, the books themselves are imbued with magical powers due to their contents or as a security measure to prevent unwanted individuals from viewing their contents. This sometimes causes them to gain sentience to some degree.

General Information
According to Ms Smith, a grimoire was originally just a normal book, but due to the magic that was imbued into it, it is now a kind of living creature or Liminal, although whether the book is truly "alive" is difficult to define. It is not known who created the grimoires, or where the magic used to make them came from.

A grimoire absorbs information from its surroundings through some unknown mechanism and then used that information to affect its environment through magic.

Trivia

 * The ancient Egyptians thought magic could be performed by reading and performing specific incantations, and used collections of written spells in various forms; all collected together in bundles that will later become known as "books". Writing itself was also once considered a magic art.
