East Faerûn bordered the eastern expanses of the Sea of Fallen Stars. Here the sea formed a long arm that traveled to the east before turning south to become the Alamber Sea. The northern nations of this mysterious area were termed by some people as the Unapproachable East and the southern nations the Old Empires, and, for a time, the Empires of the Alamber Sea. Many of these nations allowed slavery, and depended on slaves for much of their economy.
