Essos, often simply called the east, is the largest of the four known continents in the world. It lies east of Westeros and north of Sothoryos and Ulthos, stretching from the Shivering Sea in the north to the Summer Sea in the south, and from the narrow sea in the west to the lands surrounding the Jade Sea in the east, if not farther. Essos is populated by many different peoples and has a vast and varied geography.
