While I wait in a 4000 player queue...
I didn't see a thread about this, but as a roleplayer, I really like talking about the real-world cultural inspirations for in-game societies so I can understand them better. After my thread about Thavnair, it's probably not surprising that I leaned forward in my seat when I saw Gyr Abania using Middle Eastern cultural themes. I'll admit that I'm a little biased against Ala Mhigo for story reasons, and I'm really interested in Thavnair, so at first I thought it might be stepping on my favorite island nation's toes. But after more digging around, I'm pretty confident in saying that Gyr Abania is more Turkish, and Thavnair is more Persian/Indian.
I first noticed because of the Ala Mhigan Kilij, since a kilij is a Turkish sword. But that alone isn't really enough to jump to conclusions.
I reserved judgment until I actually got to see the inside of Ala Mhigo (mild spoilers): http://imgur.com/a/UP53G
And then I went looking at pictures of Turkey and its architecture: http://imgur.com/a/aQ8fk
I was like, "Hey, that sure looks a lot like the Fringes, the Peaks, the Lochs, and all the striped stonework, pointed arches, geometric patterns, and blue tiles you see in Ala Mhigo." Then as I was flying over the Peaks, I looked up at the ark and remembered that in the biblical story, the ark came to rest on Mount Ararat, which is in Turkey. So, at this point I'm pretty confident about it, and Thavnair's cultural themes are safe from the warlike savages.
