Mondain's Legacy is the seventh expansion to the Ultima OnlineMMORPG, featuring a new playable race, elves, along with a new skill and several new dungeons. This expansion focused content more on existing and veteran players, rather than trying to draw new players. It was also the first UO expansion to only be available via digital download instead of the traditional retail box.
Mondain was an evil wizard in the first Ultima game and one of its main villains. There are many references to Mondain throughout the many Ultima games. In Ultima IV, the Skull of Mondain makes an appearance as an artifact that is integral to the game.
