Throughout the Evil Dead trilogy there were variants of the book: in The Evil Dead it was the Naturan Demanto, a copy of the original Necronomicon, and the “real book” is the one shown in Evil Dead 2. Although there’s a lot of evil and darkness in the Necronomicon, it also mentions “The Chosen One”, that who can fight the evil summoned through it. Those possessed by the demon unleashed through the book can go back to normal if the book is exposed to the sunlight, which is how Ash was freed in Evil Dead 2. The power of the book is such that it can affect inanimate objects too, as seen in The Evil Dead with the trees. The Necronomicon Ex-Mortis also includes information to open a portal to travel either to the past or to the underworld, home of the Deadites. It’s full of dark passages and spells, the most notable one being that which opens a portal to the underworld so that the Kandarian Demon and the deadites can be released. The cover of the book is made of the flesh of the “Damned Ones” and it was written with blood. Their main purpose was to use the Necronomicon as a weapon against humans – and they succeeded. In the Evil Dead universe, the book was written by the 'Dark Ones”, Eldritch beings who are not demons but are not human either. Its first appearance was in the short story “The Hound” in 1922, and since then, many other authors and artists have taken it an added it to their works.

The Necronomicon Ex-Mortis was taken from the works of H.P Lovecraft.

Evil Dead 2 retold part of the story and added a different version of the book, now called Necronomicon Ex-Mortis, and quickly became a legend itself, with a number of libraries and pranksters claiming to sell copies of it.
