I'm not entirely sure as I haven't read it specifically. But generally, it might be about dark, mysterious, and perhaps supernatural themes given the 'necronomicon' which is often associated with the occult in various fictional works.
Well, it's about Lovecraftian stuff. You know, H.P. Lovecraft created this whole universe of cosmic horror. The Necronomicon in his works is like this book of forbidden knowledge. In the graphic novel, it might show different scenarios from his stories. For example, it could depict the cults that worship the ancient and evil entities, or the hapless humans who stumble upon things they shouldn't. It's a visual take on his terrifying concepts.
I'm not entirely sure as it could vary a lot. It might be based on the 'Necronomicon' which is often associated with Lovecraftian horror. Maybe it involves a story with dark and mysterious elements, strange creatures, and a sense of the unknown.
The Necronomicon is a fictional creation. Despite some claims, there is no evidence to suggest it is a real spell book. It was made popular in horror literature, particularly by H.P. Lovecraft. So, it is fiction.
If the Necronomicon spell book was not fiction, it would open up a whole new realm of study and danger. There would be ethical questions about using its spells, and the power dynamics it would introduce into society would be chaotic. But, as of now, it remains firmly in the realm of fiction. It was designed to tell spooky stories, not to be a real - world manual for magic. There is no evidence to suggest it has any basis in reality, and most likely it never will.
