Teshol

Teshol, also called "The Center of the World" is the continent on which the main campaign takes place. It has been, for about 5,000 years, segregated from the rest of the world by a gigantic, unending storm called the Ring of Storms. 
Outside of the Ring of Storms, Teshol was once regarded as most likely being a barren, destroyed wasteland due to being the center of Tiamat's rise. Since then, the people of Greater Ouern who have either passed through the ring or been informed of the state of Teshol have been surprised to learn of its large population and varying countries.
