The Mithradian empire is a southern island nation bordering the Kingdom of Rhodoks, the Sarranid Sultanate and the Merchant Republic of Zendar. It is a very non-aggressive faction and they do not tend to do much that affect wars. The empire is led by Emperor Constantinus.
The Mithradian Empire is closely related to the Byzantine (Eastern Roman) Empire around these times, as they were in constant decline and facing much external aggression.
