After the introduction of the Burgundians and the Sicilians, it makes sense to introduce one of the civilizations that, during the Middle Ages until the modern age, dominated the Mediterranean, that is not represented at all by Italians except for Silk Road, maybe. I refer to the Republic of Venice, the civilization then will be called the Venetians. I know that it is difficult to try to create a new civilization while managing to make it balanced. Below is the idea, I hope it will interest you.

Historically, there were two choices for the unique naval unit: the slim galley, agile and excellent for quick maneuvers, or the galeazza, a large, tank galley with deadly cannon broadsides, referred to as a true castle of the sea. Both boats have long been used by the Venetian navy, and in the famous Battle of Lepanto (1571), were used both.
