Britannia, from Ultima IV: Quest of the Avatar
After the destruction of Exodus, a huge cataclysm destroyed most of the world and reshaped it forever. Mountains rose, lands sank, and in the end the world changed into what we have come to known as Britannia. Lord British emerged as the major ruler on the land, and seeking to have a way to control his subjects he called forth for a champion of virtue to be found.
