(NOTE: This expansion is now part of the base game, so it is no longer available independently) New enemies threaten the Tetrarchy! Do you think you and your co-Emperors can handle already the enemies of the Roman Empire? Then beware, new enemies arrive to breach the walls of Rome! From eastern Europe, the Gothic army crosses the Danube unstoppable. From the sea, Pirate ships challenge Roman rule over `your' Mare Nostrum. Hopefully, a young Roman general, the Dux, may come to your aid! This extension of Tetrarchia includes three independent modules, the Dux (a new orange Roman meeple), the Pirates (a new black fleet), and the Goths (a new black Barbarian meeple). They can be combined in any number with the base game and with any of the five official variants, providing and endless list of new challenges. But don't worry, the rules remain simple and the playtime fast!
