Book of Vile Darkness

The book of vile darkness was an artifact that was used as a reference work by evil people.

Description
There were a total of six copies and at least eighteen fakes and botched copies of it. The original from Vecna, a deity from Oerth, was a book with a cover made from human flesh from the face part and bones from a demon. The latter was made into the book's metal binding via magic. It had&mdash;at least for normal people&mdash; unintelligible symbols on the cover.

Powers
Reading the entire book of vile darkness took about seven days. Upon completion, an evil divine spellcaster, such as a cleric, gained enough insight that it allowed him or her to grow in power and become more insightful into matters in general.

To neutral people, the book was dangerous. Reading it physically harmed them and their personality changed to that of an evil person. If they also happened to be a divine spellcaster, the book sapped their essence away but conferred no benefits.

To good people, even touching the book was dangerous. Looking into it, bought them the hostile attention of a fiend who attacked them on the night they looked into the book, albeit it happened only four in five times. If a good divine spellcaster tried to read the book, the person died or at least went permanently insane like under an insanity spell and the book drained his or her essence without conferring any benefits.

The books' most fearsome ability was that they were easy to edit. Every time a book of vile darkness fell into the hands of someone, that someone took out old pages and added new pages, changing the content according to the current owner's priorities.

History
The first content of the book of vile darkness was penned by a Vasharan spellcaster millennia before the 14 century DR. At that time, it was only one single scroll with that spellcaster's ideas in it. Later, the scroll fell into the hands of a priestess of Nerull, a god worshipped on Oerth, who tripled the content by adding her knowledge into it. This trend continued and various evil clerics of different faiths came into possession of the scroll, added their knowledge to it, and the scroll fell into the hands of a different owner. At some point in history, it fell into the hands of Vecna, who did not just add his knowledge but transcribed the scrolls into a bound book, the book of vile darkness. The book fell into the hands of worshipers of Erythnul who made of copies of the book. Only six perfect copies existed, the rest was in some way imperfect. Baalzebul was also rumored to have owned one and to have made his edits into that copy.

At least one of these perfect copies existed on Toril. Among its content was a description about Atropus and what needed to happen so that he came and ended the world.

Reputation
The books enjoyed an excellent reputation as far as reference works for evil matters went.
