Heya! So... I'm thinking of making a new character in FFXIV and I was wondering if anyone knew any lore about the region of Thavnair or the City-State of Radz-at-Han.

What I know so far:

-It exists beyond the Jade Sea.
-It is the origin of the alchemical concoctions "Thavnairian Mist" and "Radz-at-Han Quenching Oil" as well as the Giantsgall Weapons.
-One of its most popular beverages is flavored milk known as Lassi.
-It has a bustling shipping industry.

What I assume (but could be wrong):

-Radz-at-Han shares parallels with the Ottoman Empire (Middle-Eastern Culture, intellectually and culturally bustling, ruler is a Sultan or similar, etc.)
-They are neutral towards Garlemald and Eorzea, their shipping industry and mastery of trade agreements have bound Garlemald's hands, willingly trading with both equally.
-The People of Radz-at-Han have Middle-Eastern Naming Conventions.

How much of this is wrong? How much is right? How much info do we really have on Thavnair and Radz-at-Han? Thanks!
