- Dungeons and Dragons: The Book of Vile Darkness 2012

Two thousand years ago, Nhagruul the Foul, a sorcerer who reveled in corrupting the innocent and the spread of despair, neared the end of his mortal days and was dismayed. Consumed by hatred for the living, Nhagruul sold his soul to the demon Lords of the abyss so that his malign spirit would survive. In an excruciating ritual, Nhagrulls skin was flayed into pages, his bones hammered into a cover, and his diseased blood became the ink to pen a book most vile. All those exposed to the book were driven to madness or so corrupted by the wicked knowledge contained within that they had no choice but to turn evil.
