The surface world is ruled by the Empire. Its power is absolute. Its control is unchallenged. And, as a soldier of the Empire, you have a good, comfortable life ahead of you. But then a rebel named Dorikas tried to assassinate the Empress, and everything went wrong for you.
The villain fled somewhere into Avernum, an underworld nation of eccentrics, misfits, and barely civilized monsters, most of whom hate the Empire. And that is where you are going. You must find Dorikas, while dealing with spies, betrayal, and assassins at every turn.
The enemy is waiting for you. You will only survive his attention with the help of these strange cave dwellers. If, of course, they donít kill you first.
