The Tome of the Black Arts is a legendary book said to be a collection of the notes by some of the most infamous monster scientists in history. Started by the mad scientist Nahze hundreds of years before, the book was passed through generations until it made it into the hands of the priestess Nada, who added her own notes from her experiments with the Zan species and her time spent studying in the Tower of the Miasma.
The Tome somehow found its way into the library at the Elives School, where it stayed hidden for almost 50 years until a curious student found it and began using the knowledge inside to illegally modify monsters once again using technology and magic. The teachers at the school eventually band together to destroy the artifact, and create a new one in its place - the Tome of the White Arts.
