The new Magicked Carpet mount on the Mogstation says

This plush mount was clearly woven with the greatest care using techniques traditional in the Near East. The origins of its more magical elements remain unclear, as the only extant historical records regarding flying carpets pertain to one given to an ancient king of Corvos by a faerie queen, and it is highly unlikely that said carpet would have been adorned with a motif of Namazu and moogles─as this one most certainly is.
I don't remember ever hearing about this Corvos place. Obviously it's somewhere in the Near East, though. Has it ever been mentioned before or is this a new country on Ilsabard to maybe look forward to visiting someday?
