The Age of Harmony

The first civilisations of Aiaos were Ladon and Titanis.
Ladon was the draconic domain at the heart of the World, controlling the centre of the great supercontinent of Aiaor. Titanis was the skyborne empire of the Titans, based in nine flying cities, but governing the remainder of the surface.
Created in the era of absolute harmony, these two empires and their masters were ravaged by the Colossus War, and the Cataclysm that broke Aiaor into the three continents. All that remained were the failing sky cities, now controlled by mortal Giants, and the Dragonborn imperium in the archipelago of Ladonia.
After the Cataclysm, The Mortal Age began.
