Many riches pour into Rome. But the most precious - and probably most profitable - treasure is garum, a spicy fish sauce. The highest quality and most valuable garum of the entire Roman Empire comes from the factories of Troy in Lusitania and Baelo Claudias in Baetica, Spain. ... Here you will find fish, salts and clay of the highest quality to make the amphorae that, filled with the precious sauce, find their way to Rome. The most influential families in the empire pay any price to acquire even a small amount of this prized ingredient. On imperial orders, your mission will take you to the Iberian Peninsula to produce the best garum in the empire.
