The Shivering Sea lies to the north-east of Westeros and the north of Essos, separating the latter from the northern polar ice cap. Inlets of the Summer Sea include the Bay of Dragons and the Gulf of Grief. The extent of the ocean south of the Summer Islands is unknown.
The Summer Sea lies to the south of Westeros and Essos, dividing the latter from Sothoryos. Arya Stark is currently exploring the sea. No-one has successfully crossed the Sunset Sea with any reliable information about any landmasses that might lie beyond. The Sunset Sea lies to the west of Westeros. It is said to be a haven for plagues and dangerous animals, and has not been explored much beyond the northern coastal regions. It is a large continent consisting of deserts and jungles. Sothoryos: With relatively little known about it, Sothoryos is located south of Essos, on the far side of the Summer Sea.
Much of the continental interior west of the Jade Sea is ruled by the tribal warriors known as the Dothraki. The far eastern coast of Essos is unexplored, as it lies beyond legendary Asshai and the forbidding Shadow Lands. Further east is Qarth and the fabled Jade Sea, which Essos partially encloses. The western edge of the continent is controlled by the nine Free Cities, while the city-states of the Bay of Dragons are located in the south-central region. It is larger than Westeros but less densely populated.
Essos: Separated from Westeros by the Narrow Sea, Essos extends eastwards for many thousands of miles. Most of the action in Game of Thrones occurs in Westeros. Further north lies the Land of Always Winter which is assumed to be governed by White Walkers under the authority of the Night King. The northern border of the Seven Kingdoms is marked by The Wall, beyond which lies mountainous tundra inhabited by the Free Folk. Most of the continent is unified as a political entity called the Seven Kingdoms, ruled from the King on the Iron Throne in the city of King's Landing. Westeros: Located in the far west of the known world, Westeros extends southwards from the northern polar icecap for approximately 3,000 miles.
