So most probably thanks to Romans here on Earth, we refer to everything East of Ancient Rome as The Orient, hence Oriental.
At first, I thought the terminology was a bit out-of-place in Eorzea, and grudgingly suspended my disbelief slightly higher in order that the fantasy remain complete (yeah, looking at you Hollandaise Sauce).
But then it occurred to me that the Garlean Empire is heavily influenced by the Roman Empire, including the use of Latin. The opposite of 'Oriens' being 'Occidens' (West) being familiar nomenclature already.
So happily my immersion hasn't been ruined, as clearly Hydaelyn's Orient lies to the East of the Garlean Empire and hence these goods have come from there (plz insert Moose lore database character quotation below).
Of course that means that the Garleans regard Eorzea as one.. big.. occident! :cool:
Still not happy about that sauce though, which is clearly interdimensional in origin.
