Echoes of an Empire introduces a whole slew of new content. The main addition to the game is the new region Errac and its main city El Dorado. This region's aesthetics are inspired by classical Central American ruins, bringing a peaceful harmony of nature and man that is a rare find among games. El Dorado is built around a Cha'acan temple, now protecting the survivors of the cataclysmic events of Caebolan. The Erracan people of El Dorado are proud and resilient. It will not be easy to gain their trust and much more difficult to cultivate their respect.
