One of the exiled and imprisoned mages of the Cosmic Library has escaped and is now invading with the demonic horde to get their revenge. The teenage sorceress Ashe stands out to stop the invasion and protect the Cosmic Library. Other mages transform into sentient Spellbooks, so that their powers can be used by Ashe.(Storyline via IGDB)
