East Faerûn East Faerûn bordered the eastern expanses of the Sea of Fallen Stars . Here the sea formed a long arm that traveled to the east before turning south to become the Alamber Sea . The northern nations of this mysterious area were termed by some people as the " Unapproachable East " and the southern nations the " Old Empires " , and , for a time , the " Empires of the Alamber Sea " . Many of these nations allowed slavery , and depended on slaves for much of their economy . After the Spellplague , a few new nations arose in this regions , including a interloper nation from Abeir . Regions . Aglarond . This nation lay on a long peninsula that jutted westward into the Sea of Fallen Stars . Its landward border joined it to Thay , a powerful enemy that Aglarond constantly opposed . Much of the peninsula was occupied by the Yuirwood , a forest home to half - elves and old ruins . Along the eastern border was the Umber Marshes . The capital city was Veltalar , home of a powerful sorceress known as the Simbul . Altumbel . A small , isolated kingdom on the western end of the peninsula it shared with Aglarond . Chessenta . A war - torn region of cities leagued against each other in a group of alliances , during most of its history this area was a nation in name only . It was located along the southern coast of the inland sea , between Chondath to the west and their former rulers in the old empire of Unther . The major geographic features were the Akanmere Lake in the west and the wide Chessenta Bay along the coast . The nominal capital was the port city of Cimbar . During the Spellplague , Chessenta was nearly destroyed . The Karanok s seized control of the surviving lands , moved the capital to Luthcheq and for century Chessenta was a unified nation at last . This situation wouldn ' t remain , however , and in the late years of the 15th century DR , Chessenta fragmented again into independent city - states . Chondalwood . This was a long , forested region to the south of Chondath and Chessenta . It was a wild region , home to elves , sylvan creatures , strange walking plants , and savage druid s . It lay just to the north of the vast region of the Shaar , being separated by the Firestrap mountains . Mulhorand . An ancient land and empire that lay at the eastern extreme of the inland sea far to the east toward the Hordelands . In times past this nation was ruled directly by their deities . To the east were the Plains of Purple Dust and Murghôm . The capital was the ancient port city of Skuld . Mulhorand was destroyed during the Spellplague , and in the following century the region became the nation of High Imaskar . This changed in the late years of the 15th century , when the mulhorandi rebelled and reclaimed their lands , rebuilding their old nation anew . Murghôm . This was an inland nation of farmers and horsemen who dwelt about the Brightstar Lake . They were located to the east of Mulhorand , and gained partial independence from their old rulers in that land . It was separated from the vast Hordelands to the north and east by the Great Wild Wood . After the Spellplague , Murghôm was conquered by a group of dragon princes . Okoth . One of the oldest empires of Faerûn , Okoth was one of the three sarrukh nations from the Days of Thunder . The sarrukh returned to Faerûn and began to rebuild their empire after the Time of Troubles . As of 1479 DR , they were still rebuilding their old nation and preferred to maintain a low profile , and so only a handful of scholars knew about them . Thay . This eastern nation was most noted for the evil , Red Wizards who ruled the land , and their extensive use of slavery . Much of the land sat atop a large plateau , with a second plateau and the volcanic Thaymount mountains atop that . The southern border joined the Alamber Sea , an eastern arm of the Sea of Fallen Stars , as well as Mulhorand . To the north was Rashemen , and to the west Thesk and Aglarond . It was separated from the hordelands to the east by the Sunrise mountains . The capital city was Eltabbar . Tymanther . The interloper nation of Tymanther was originally Tymanchebar , an abeiran nation . In the wake of the Spellplague , Tymanchebar was almost destroyed and a big region of it was sent to Faerûn , replacing Unther — which in turn , was sent to Abeir . The surviving dragonborn of Tymanchebar soon tamed the region and built a new nation that they called Tymanther . After the return of Unther , in 1486 DR , Tymanther lost all of its northern regions , who were reclaimed by the untherites , but maintained and fiercely defended their remaining territory , that was composed of the lands near the Smoking Mountains and south of the River Alamber . < ref name = " TDYK / Hardcover - p483 - 484 " > < / ref > Unther . Another older empire , this land lay to the west of Mulhorand , on the west bank of the Alamber Sea . The western border of Unther was next to Chessenta . For most of its story , the capital of this land was the city of Unthalass . The southern part of this land was invaded and occupied by Mulhorand in the late years of the 14th century DR , while only a small nation at the north end retained their freedom . The capital of the unoccupied portion of Unther was the port city of Messemprar . Unther was utterly destroyed during the Spellplague , when the land of Tymanther fell upon it . A few untherite lands were transported to Abeir because of the Spellplague . Most of those lands returned to Faerûn in 1486 DR , and the untherite were able to reclaim the northern region that was part of their old nation .
