From the lorebook....
Quote:To the south of Ilsabard lies a great sea known as the Bounty. The abundance of sea life combined with its central location in relation to the Three Great Continents has historically seen civilizations on the islands of the Bounty thrive, even during the calamitous Umbral Eras.
The most prominent of those civilizations would have to be that of Radz-at-Han, located on Thavnair-the Bounty's largest landmass. An ancient city-state with a history stretching back thousands of years, Radz-at-Han is best known as the birthplace of modern alchemy. It is interested to note that, despite having a very limited outward military presence, the city-state has succeeded in forging a non-interference treaty with the Garlean Empire, ensuring their independence while mightier nations fall about them, and as thus, Radz-at-Han remains an active hub for trade between Eorzea. However, it has been noted by some that the treaty was only formed so that Garlemald could obtain items from Eorzea via Thavnair, as official trade between the regions was frozen after the Empire's failed invasion twenty years prior.
