Avernum: First Trilogy Avernum Avernum, the first game of the Avernum series, features a party of characters thrown from the surface world into the subterranean Avernum. Once here, the player discovers a culture that has formed from the outcasts of the Empire above: a culture beset by constant warfare and monsters galore.

Besides countless side quests along the way, the game offers three primary quests: killing the demon Grah-Hoth, discovering a route back to the surface, and assassinating Emperor Hawthorne of the surface world.
