Yeah, the Heavensturn npcs do seem rather contradictory, especially given the fact that they are clearly Asian-influenced, and that the Domans seem to share similar cultural aspects (the refugees call chocobos 'horsebirds', just like the Heavensturn ones did, and interestingly, all seem to wear the same outfit with an Asian character written on their backs (whether this is their nation's 'crest' or something cultural I have no idea, but it seems interesting all the same).
