Located on the western coast of the mainland of Extremus Terra, Archo comprises the planet's largest forest. Nearly all of Archo's terrain is forested, with the lone exception being the rocky coastline that separates the ancient trees from the rough, cool waters of the Sea of Terra. There are rumored to be a number of settlements of note in Archo, but the country is home to the reclusive Ipsum Scelus, and thus little is known of the location and size of such civilizations.
