A grimoire is a textbook of magic, typically including 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, and demons. Some cases tell that the books themselves are believed to be imbued with magical powers, others follow the belief that the words themselves have hold the power.
There were three ancient books crafted that every aspect of their creation was built with layer after layer of magic and enchantments, making the tomes themselves into talismans of power.
The Key of Solomon: Was crafted by King Solomon himself. Solomon wrote the book for his son Rehoboam, and commanded him to hide the book in his sepulchre upon his death. After many years the book was discovered by a group of Babylonian philosophers repairing Solomon's tomb. None could interpret the text, until one of them, Iohé Grevis, suggested that they should entreat the Lord for understanding. The Angel of the Lord appeared to him and extracted a promise that he would keep the text hidden from the unworthy and the wicked, after which he was able to read it plainly. Iohé Grevis then placed a conjuration on the book that the unworthy, the unwise or those who did not fear God would not attain the desired effect from any of the workings contained therein.
Arbatel de magia veterum: Unlike some other occult manuscripts that contain dark magic and malicious spells, the Arbatel contains spiritual advice and guidance on how to live an honest and honorable life. The focus of the Arbatel is on nature, and the natural relationships between humanity and a celestial hierarchy. It centers on the positive relationships between the celestial world and humans, and the interactions between the two.
The Golden Grimoire: said to be the Book Of Shadows of Merlin the Magician, a glipse into hell to do works of good. The book contains lore and alchemy alike, with no small amount of prophecy.
