The Ultima series was created by Richard Gariott and includes Ultima 1-9, Ultima Underworld 1 and 2, and Ultima Online. In the Ultima universe, Lord British is Richard Gariott's alter ego and is the benevolent ruler of the medieval land of Britannia. The player usually takes the role of the Avatar and wanders the land of Britannia trying to fix whatever's gone wrong this time.

I may describe the systems of magic in the Ultima series at some point.
