The Eastern Realm is an expansion for the game The Settlers: Rise of an Empire. The expansion adds a tropical monsoon season. Monsoons prevent fish from being fished from the turbulent waters and grain from being grown. It also adds a new knight - Saraya.
In this expansion, players pit themselves against evil goddess Khana and her cult. Also, the hypnotized mogul Prahphat and his minions represent an added menace.
