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.
