Britain, the City of Compassion, and one of the oldest cities in Britannia, having been founded well before the First Age of Darkness. It did not become the City of Compassion, however, until after the destruction of Exodus, when Lord British declared the Eight Virtues.

Once located south of Castle British, the thriving city has literally grown up around the Castle, bordering almost all of Brittany Bay. Its largest growth spurt was seen during the period of peace and prosperity after the raising of the Codex, up until the disappearance of Lord British and the arrival of the Shadowlords. during this time the areas surrounding the Castle were considered separate villages in their own right, being North, East, and West Brittany. This, however, did not last for long, and the City of Britain eventually assimilated these small, rural areas. If its expansion does not slow, it is likely that Britain will absorb the farming communtiy of Paws in the near future.

Britain is certainly the largest of all the cities in Brittania, and it is home to almost every kind of shop imaginable, including the Farmer's Market and the world famous Iolo's Bows. Also in Britain is the Bard's Conservatory and the Wayfarer's Inn, both of which have played prominent roles in the Avatar's journies. Lying on the road between Minoc and Trinsic, Britain attracts many merchants to the area, and it is those merchants who eventually settled down there, building their shops and spurring Britain's growth.

Before it was disbanded after the destruction of the Black Gate, the Fellowship, led by the sage Batlin, was based in Britain. The Royal Mint, before it was transplaced with an odd lighthouse that was recently discovered to be from the Serpent Isle, was based in Britain. The Royal Theatre, founded by Raymundo of Britain, is located in Britain as well. The Royal Museum, once called Lord British's Museum of Oddities, is yet another famous building within the confines of Britain.

Britain is becoming increasingly more important in the national politics of Brittania, and with the disbanding of Yew, it now plays an even more prominent role in Brittanian society.
