Flying city

Flying cities were a common fixture during the Age of Arcanum. They were able to fly due to enchanted brumestone. Only the wealthiest and most powerfully arcane cities during this era were flying cities, and terrestrial cities were still common, particularly among the more religious population.

Most of the flying cities crashed during the Calamity, some more devastatingly than others. Few cities of the post-Divergence era are either survived due to their isolationist nature, carefully avoiding the battles of the Calamity, (e.g. Jovatthon) or were reborn from the ruins from the Age of Arcanum (e.g. Draconia).

Pre-Calamity

 * Aeor: A highly advanced city crashed by both the Prime Deities and Betrayer Gods into the arctic region now known as Eiselcross early in the Calamity.
 * Avalir: A powerful mageocracy and sister city to Cathmoíra. Destroyed at the very beginning of the Calamity.
 * Kethesk: A primarily dragonborn city that crashed into the Dreemoth Ravine. Some of the survivors built Draconia.
 * Lathras: A smaller flying city that Aeor considered attacking to test a weapon.
 * Zemniaz: Home of the mageocracy of Zeidel, and Halas Lutagran. Crashed into central Wildemount; the Zemnian people are descended from the survivors.

Post-Divergence

 * Draconia: Rare post-Divergence flying city, with a primarily dragonborn population, built from a "shard" of Kethesk. Destroyed by Vorugal during the Chroma Crisis.
 * Jovatthon: An invisible flying city-state of cloud giants, making circular routes above Tal'Dorei. The city holds annual gathering of the Council of Seven Scepters.
 * The Silken Squall: A floating tent city traveling the world of Exandria. The city is guided by the Wyvernwind family that lead the fractured air genasi people.
 * Tempestar: Home of the storm giants. By 812 PD it had long since been destroyed, but it is unclear if it fell during the Calamity or at an earlier or later date.
