From the campaign:
Canterbury is a game we've developed over the past several years, and it is one that we believe in strongly. The game is set in the late 6th century A.D., when the Saxon King Ethelbert established the old Roman city of Canterbury as his new capital. In Canterbury, players represent Saxon Lords who are charged with building the city into a prosperous capital. The Saxon Lords must use the city's meager starting resources to build up the 25 districts of Canterbury and to provide key services to its citizens, including water, food, religion, defense, commerce, and culture.
