I read on the WWW {World Wide Web} that it was the Bible eviled with blood. As the other books I needed to properly know about to accurately hunt magicians, the tomes, are several mage books in one in hopes to out wizard a archon. 

A sorcerer is a wizard that has gone mad in any roleplay, because they made tomes instead of being a mancer (unknown wizard) and it brought them closer to their modern reality, but they were using magic and that thought always corrupts them into madness. But three magic users, I found, would exist rightfully in a fantasy; The archon, a wizard that made their madness teleport them through time where they created a transdimensional mage guild, the wizard, the one that was able to escape the madness (they quit tomes by quitting vsing other magic users {I imagine}), and the magician, the one that got people to pay him to survive (and they would feebly try to make their mind a show).

The grimoire is, by my intelligence, created for a demonic summoning. They took the holiest book, branded it with their soul through madness, in hopes of siphoning evil through magic to empower themselves (pobably through stopping time travel to get to God)... The whole idea of it being the baddest is because it's the baddest. I'm certain that that is how demonic beings like, for example, a "lillith", happen to have human attributes because by roleplaying rights they teleported with magic to a hell- and mastered the roleplay of magic there as that.
