Caesar sent you to a rich province in Britania, but you thought Rome is far away and decided, not to serve him any more and to be king on your own. This was the worst decision you ever made...
Caesar cuts of your trade - of course there are lots of smugglers, but they have their own prices... And you will have to force back his legions and the allied britons. Belive in the gods, your troops and your patriotic people and win the independence!
