In the year 846 A.D., what was the capital of the great Empire has become a ruined and semi-abandoned city. Even so, Rome remains eternal, since the Pope rules there and the bodies of Christ's apostles Peter and Paul rest, surrounded by immense wealth. The Church hides great treasures.

Meanwhile, in the background, next to the thrones of kings, caliphs, emirs and emperors from all over the Mediterranean, whispers of conspiracies and war trumpets can be heard.
