Ubar

Ubar is an ancient city buried beneath the Rub' al Khali desert, dating to 7,500 BCE, or 4,000 years before the rise of the first human civilization in Mesopotamia. It was discovered by Lorenzo Cabot during the 1894 Empty Quarter expedition.

Background
Ubar was built by a non-human species and filled with structures and artifacts best described as strange, with tools not made for human hands, "disturbing" geometries, proportions, and carvings that hint at dimensions beyond human knowledge.

The descendants of the region would eventually create modern human civilizations, beginning with the basin of the Tigris and Euphrates. The collapse of Ubar would be immortalized as myth and legend, a cautionary tale of a civilization destroyed by its own hubris. It was not until Lorenzo Cabot's expedition to the Empty Quarter of the Rub' al Khali that the first archaeological evidence of Ubar and the lost civilization was uncovered and the Atlantis of the Sands was verified to exist. However, he made only one expedition to the Empty Quarter, and - combined with his famed arrogance and short temper - he was dismissed as a hack.

Appearances
Ubar is mentioned only in Fallout 4.

Behind the scenes

 * Ubar shares its name with the legendary lost city in Arabia known as Atlantis of the Sands, as well as the lost city of the same name mentioned in the Quran, both of which have been theorized to have been possibly located in the Rub' al Khali.


 * H.P. Lovecraft describes a similar city in the book The Nameless City.
