East Roman Empire

Overview
East Roman Empire is a post-roman faction. It can be easily reformed into Byzantine Empire if it's owned by a player. East Roman Empire is much weaker than the West Roman Empire from both economic and military aspect. However, the max province count of East Roman Empire much higher than the West Roman Empire. East Roman Empire also has a relatively low lifetime of just around 200 years (Without reforming into Byzantine Empire by a player).

AI
The AI of the East Roman Empire is relatively non-aggressive towards its neighbors (Except West Roman Empire). East Roman Empire rarely declares war on its neighboring countries aggressively. However, it would smack Byzantine rebels as hard as they can just like every AI does to rebels.
