Britannia (location)

Britannia is a land outside the Roman Empire which Emperor Claudius has not been able to conquer over the years despite numerous attempts. The land features Celts including the Cantii and Regni tribes, lead by the mystical Druids. Claudius has sent his General, Aulus Plautius, to finally accomplish the invasion and achieve something that goes beyond Rome. 90 years before the events of the show, Julius Caesar travelled to Brtiannia to take advantage of their tin deposits, but were driven back by the Druids and the Celts.
