"By following the river, we arrive at the sea." - Plautus Come aboard and travel the seas. Exercise your natural skills for trade and interact with more players than before. You like the interaction, but you’re feeling more bellicose? Well, invade them rather than trade with them, or do both, after all, you rule on the seas. Control military and commercial maritime routes, and discover a new way to play. This expansion adds one additional card to each Age per player. The new powers and abilities added on theses cards are mostly Maritime Trade and Invasion. Players may now initiate trade and military conflict with any other player, not just their immediate neighbors.
