Revelations from Gamescom 2019

[Enkidoh]

Qarn (which definitely has Ancient Egyptian influence) was of Belah'dian origin, if I recall correctly? Which incidentally was a nation whose patron deity was Azeyma... And in Qarn HM there is this puzzle-seal-thing with the sun / moon / star gems...

Crud. Now I want to know more about Belah'dia.

Qarn wasn't built by Belha'dia, it was already old before Belah'dia was even formed (the description for it in the Duty Finder mentions how it predated "this Sixth Astral Era civilization" and that generations of Belah'dian sultans added more and more of their own embelishments and modifications to the place, suggesting it was definetely at least pre-Sixth Astral Era, possibly even older.

My guess is something around Third Astral Era, aka, around the time of the rise of the Allagan Empire, as Allagan structures have always been part of Thanalan since 1.0, with the 'Royal Allagan Starway' and 'Royal Allagan Sunway' roads still in use in the present day, so an Allagan-era origin for Qarn is as good as any).

Also those minaret-like structures found partially buried in the sand in Southern Thanalan like at Byregot's Strike are very similar to the structures found near the Crystal Tower in Mor Dhona at Saint Coinach's Find, and also, Qarn's structure resembles the other ruins found in Eastern Thanalan around Highbridge and the appropriately named 'Invisible City' soooo... I'll leave you to draw your own conclusions.
