Necronomicon

The "Naturom Demonto," though it becomes the "Necronomicron ex Mortis" in the sequels (after Sam Raimi learned about H. P. Lovecraft and renamed the book as a Shout-Out). Usually shortened by characters to either "the Necronomicon" or "the Book of the Dead".

Example of:
Tome of Eldritch Lore
