The continent east of the Seven Kingdoms, called Essos, is separated from it by a narrow sea. It is much larger than the continent of the Seven Kingdoms (I: 23. SSM: 1, 2, 3)
The Jade Sea is far to the east, and the lands there are half-fabled (I: 23)
Vaes Dothrak is east of the Free Cities (I: 23)
Beyond Asshai lie the Shadow Lands (I: 86)
The Dothraki Sea is a huge expanse of plain lands beginning far east of Pentos (I: 190, 193)
Norvos is east of Pentos, a land of rolling hills and terraced farms with small villages sitting behind white stucco walls (I: 192)
Valyria left many roads, as old as a thousand years, that run straight as arrows on the eastern continent. These roads show no sign of wear or tear despite their age. Made of magically fused stone and raised half a foot off the ground to allow rain and snow to melt off their shoulders, the roads are broad enough to allow three wagons to pass abreast. (I: 193. V: 76, 77)
The Forest of Qohor is east of Norvos and takes two weeks to ride through (I: 193)
The Rhoyne is a river on the eastern continent (I: 203. II: 147. SSM: 1)
The lands or cities of Bayasabhad, Shamyriana, and Kayakayanaya are to the northeast of Vaes Dothrak (I: 490. SSM: 1)
There is a river which bounds the Dothraki sea far to the south and west of Vaes Dothrak. South of it live the Lhazreen people (I: 556)
Down river from that border of the Dothraki Sea are the slave markets of Slaver's Bay (I: 557)
Meereen is some unknown distance from the Dothraki Sea (I: 557)
Asshai lies far to the south of the Dothraki sea, at the end of the known world (I: 591)
Due east of the Dothraki sea are the red lands, a desert wasteland (II: 138, 139)
The ports on Slaver's Bay of Meereen, Yunkai, and Astapor are downriver to the southeast of the Dothraki sea (II: 138)
The red lands are a trackless wilderness of red clay, sand, and stone. There are no springs or wells, only pools of shallow and stagnant water. In the summers the riverbeds are dry, and only the tough devilgrass grows at the base of rocks and dead tress (II: 140)
Few caravans come through the red lands, but at the end of them are great kingdoms and fabulous cities such as Yi Ti, Qarth, and Asshai by the Shadow (II: 142)
In the red lands there are dead, abandoned cities built of white stone (II: 142, 143, 148)
Due south of one of the dead city that the Dothraki call Vaes Tolorro, the city of bones, the red lands end on the bleak shore of the sea (II: 148)
Southwest of Vaes Tolorro are two other cities, smaller than it (II: 148)
The trader's circle around the Jade Sea is a common route for merchant ships (II: 316)
The Qartheen naval fleet is powerful and rules the straits between the seas (presumably the Jade Sea and the narrow sea) (II: 421)
There is a mention of a place called Faros, which has the Stone Cow of Faros (II: 422)
Yi Ti is on the Jade Sea, and past it somewhere is supposed to be a legendary dreaming city of poets (II: 424)
The Free Cities appear to be almost due east from the end of Crackclaw Point in Westeros (II: 431)
The narrow sea is often stormy (III: 87)
Corsairs and pirates hunt the southern route past Slaver's Bay in the Summer Sea (III: 98)
North of Valyria the Smoking Sea is said to be demon-haunted. The waters of the Smoking Sea boil and smoke. It's claimed that any sailor who glimpsed the fiery mountains of Valyria would soon die (III: 98. IV: 440)
The groundwater beneath Astapor, such as is used in fountains, is sulfurous (III: 257, 266)
Naath is a fabled island populated by the Peaceful People (III: 258, 804)
Astapor is besides the Worm River (III: 265)
The Worm River has little islands in it near to Astapor (III: 265)
The folk of the hinterlands east of Slaver's Bay are all Ghiscari (III: 272)
East beyond the hills about Astapor lies Lhazar (III: 272)
The Dothraki sea lies north of the slave cities (III: 272)
Pentos, Norvos, and Myr are on the continent, rather than islands (III: 272)
The Astapori named the tranquil Worm River a stream. It is wide, slow, and crooked, and some of its tiny wooded islands are decorated with elegant marble statues (III: 312)
There are many small cities between Slaver's Bay and the western coast of the eastern continent (III: 313)
The Disputed Lands, where there's always fighting (III: 433, 756. SSM: 1)
There's a birchwood forest some three leagues south of Yunkai (III: 473, 487)
Meereen sits on the salt coast of Slaver's Bay beside the river Skahazadhan. Its northern wall is against the river and its western on the bay shore (III: 640, 644)
Meereen stands on a jut of sand and stone where the slow brown Skahazadhan river flows into Slaver's Bay (III: 644)
The water of the Skahazadhan is not sanitary near the city. Meereen draws its own water from deep wells instead (III: 645)
The way across the Lands of the Long Summer from Slaver's Bay is long and grueling (III: 645)
Pentos lies westwards of Meereen (III: 645)
There is a city on an island named New Ghis (III: 807)
Volantis is said to be in the west from Slaver's Bay, and may be the nearest of the Free Cities to that place (III: 807)
The journey by galley from Eastwatch to Braavos is said to be a long one (IV: 217)
The narrow sea can be rough in autumn, and autumn storms are common. In winter, the storms are worse but less frequent (IV: 217)
The direction taken in marching from the Disputed Lands to Volantis is the "wrong direction" if one means to cross the narrow sea Westeros (IV: 246)
The continent to the south of the eastern continent is known as Sothoros or Sothoryos. It is rough, plauge-ridden, full of jungles and largely unexplored (IV: 257. SSM: 1)
The Basilisk Isles (IV: 300)
The brackish waters surrounding Braavos are full of fish and shellfish, thanks to the slow, brown river that enters the lagoon from the south and spreads across reeds, tidal pools, and mudflats (IV: 315)
The Stepstones are known for their storms and nests of pirates from Lys and Myr (IV: 440)
It can be inferred that Lys and Volantis seem to be the southernmost of the Free Cities (IV: 440)
It's suggested that a journey from the Shield Islands to the far side of the narrow sea is so hazardous in autumn that two-thirds of a fleet might be lost in the attempt (IV: 440)
Near Meereen are a range of rounded sandstone mountains and the Khyzai Pass, beyond which is Lhazar (V: 34)
A ship sailing from Pentos to Asshai will take at least two years before it returns (V: 71)
The swiftest way from Pentos to Volantis is by sea (V: 71)
The city of Mantarys lies to the west of Meereen, if one follows the old Valyrian roads (V: 73)
The direct distance between Volantis and Meereen is approximately 550 leagues (V: 73)
Andalos, the ancestral land of the Andals, lies to the east of Pentos. It is said the Andals took it from the hairy men who were there before men, cousins to the Ibbense. The heart of that realm lies to the northeast of Pentos, but the southern regions are known as the Flatlands in Pentos (V: 79)
Further east beyond the Flatlands lie the Velvet Hills (V: 79)
The Flatlands contain tillers and toilers bound to the land, and orchards, farms, and mines owned by wealthy individuals in Pentos (V: 80)
The Flatlands are relatively sparsely populated, as the Dothraki occasionally pass through. The ruins of towns are testament to their passage (V: 80)
The Rhoyne lies between the Dothraki Sea and the Flatlands (V: 80)
On leaving the Flatlands, a road leads into the Velvet Hills and to the ruin of the Rhoynish city of Ghoyan Drohe upon the Little Rhoyne (V: 81)
The Velvet Hills are not very impressive. A circle of standing stones found there are said to have been raised by giants, while a deep lake is said to have been a den of robbers who now dwell beneath the water and pull fishermen down to their deaths. Deeper still into the hills one may find a huge Valyrian sphinx with a dragon's body and a woman's face, next to an empty plinth were a second sphinx had once stood; that sphinx was carried away by the Dothraki to Vaes Dothrak (V: 81-82)
The Port of Ibben is on Ibben, a large island nation in the Shivering Sea, which is the polar sea north of the eastern continent. There is nothing but ice north of it (SSM: 1, 2)
The Stepstones are a chain of large islands in the narrow sea east of Dorne and Storm's End (SSM: 1)
Vessels bound for Asshai go east through the Summer Sea and the Jade Sea, which are connected by the straits of Qarth (SSM: 1)
Maps still mark out the lands of the Andals on the eastern continent, but the area has seen so many invasions and migrations that very little of the Andal people remains there (SSM: 1)
The Free Cities are much nearer to the Seven Kingdoms than they are to Qarth (SSM: 1)
There is no connection between Westeros and the eastern continent by way of the far north (SSM: 1)
Yi Ti is to the southeast of Qarth, across of the Jade Sea (SSM: 1)
Westeros is more strongly affected by winters than the eastern continent, because it extends further north while the eastern continent's boundary is the icy polar sea called the Shivering Sea (SSM: 1, 2)
The chief city of Ibben is the Port of Ibben. Ibben is a large island (with several smaller ones around it) in the Shivering Sea (SSM: 1)
