The Necrom are seven mystical pages written by Cain after he had been scolded by the Creator for taking his brother’s life, Abel. Lucifer came to him and asked him to inscribe down the names of the seven spirits of the earth, with his blood, on seven pages. If these pages were read by a righteous man who had never sinned, it would break the gates of hell and free his brother.
Cain later realized, after he had read the pages that it didn’t work as Lucifer had promised. Only a righteous man who had never sinned could make it work, and Lucifer wasn’t helping him from the kindness of his heart. Lucifer was using him to find a way out of the hold of Ebnallon, for if you free one, you’ve freed all.
The pages were written in the first language that man spoke before the Creator changed the tongues of men at the tower of Babel. So, the tongue in which the pages were written was now lost forever.
Thousands of years had passed, and Lucifer hadn’t found a righteous man who had never sinned to read his pages. He resolved on making a man sinless from his infant age until he’s old enough to read the pages. He found an orphan who was abandoned at the gates of a monastery in Greece and became his guardian angel, keeping him from sin so that he might become the reader of the Necrom.
