Unthalass was populated mostly by humans of the Mulan ethnic group, most of them nobles. This changed after the Mulhorandi conquered the city, as most of the nobles fled and became fugitives in their own lands.
After the destruction of Unther, the ruins of Unthalass were inhabited by lamias.
Unthalass was founded in −2087 DR by the god-king Enlil, in a place were he found pearls in the west coast of the Alamber Sea. At its peak, Unthalass was considered the greatest city in all of Faerûn. When Enlil left the Realms, he named Gilgeam as the ruler of all Unther, including its founding city.
Over the years, two great floods, one in 108 DR and other in 731 DR, as well as pirate raids, reduced its once grand status. The city never recovered from such catastrophes as Gilgeam ordered to built new structures over the old instead of repairing them.
Finally, in 1358 DR, an epic confrontation between the two raging deities Gilgeam and Tiamat destroyed most of the city. Unthalass was later occupied by the Mulhorandi, who put the city under military law and claimed its slaves as propriety of the church of Anhur, while the soldiers plundered the ruins for whatever treasures they could find.
Unthalass was finally destroyed during the Spellplague of 1385 DR. As the dragonborn from nearby Tymanther were not interested in claiming the ruins, the lamias that survived the catastrophe became the "new" inhabitants of the ruined city.
In 1487 DR, after the Second Sundering brought the Untherans from Abeir to Toril, the second incarnation of Gilgeam reclaimed the city from the lamias, and began to develop a project to rebuilt the city as the capital of the reborn Unther.
