Dungeons & Dragons: The Book of Vile Darkness

2,000 years ago, the sorcerer Nagrul sold his soul to a Demon so that his spirit could survive death. His followers created a Spell Book from his remains, turning readers into darkness. The army of evil began to take over the world, but the Order of the Knights of the New Sun, with the help of the amulets of the god of light, was able to stop it. The book has been hidden, but the evil has not been destroyed — Nagrul's servants are waiting for the moment to return.
