And then there was Amaurot... Never was a city more magnificent. From the humblest streets to the highest spires, she fairly gleamed... Not that you would remember any of this.
Amaurot was the ancients' greatest city in the world unsundered. The city itself is no more due to a calamitous event involving wild creation magicks, and Hydaelyn sundering the world. The ruins of Amaurot presumably existed on the Source and all of the shards, however, only those on the First were discovered due to a lack of calamities to completely destroy it. Emet-Selch recreated a memory of Amaurot moments before the calamity taking place over the ruins within the Tempest, which the Warrior of Darkness traveled through to face him.
Another level 80 dungeon, Akadaemia Anyder, is also located within the city.
Behind the scenes
The city is inspired by the fictional capital city Amaurot in Thomas More's Utopia, with several references to the novel located within the city. More's Amaurot is described as a place where individual wealth does not exist, and everyone contributes to society as a whole. Additionally, various locations within Amaurot are locations within More's Utopia, including Achora (Achora Heights), Polyleritae (The Polyleritae District), and Macarenses (The Macarenses Angle).
The concept of the replica Amaurot is similar to the Dream Zanarkand from Final Fantasy X. Both are magical recreations of cities from highly-advanced civilizations at their height, made by their respective leaders to preserve their people's legacies in the face of a calamity. Most of their citizens express no awareness of the passage of time, the existence of other places, or even their true nature as constructs (though there are exceptions). The Convocation's act of sacrificing half their population to summon Zodiark also mirrors Yu Yevon's sacrifice of Zanarkand's remaining citizens to create the Dream Zanarkand. Finally, both cities have a connection to water: dream Amaurot exists deep at the bottom of the sea, and Dream Zanarkand far out in the open ocean.
