ooo im siberian starks truther forever, or just general indigenous arctic circle north. general aesthetics of slav/kievan rus. like kokoshnik ushanka and ryasna are canon to me. harsh, stilted syllables like in russian.
the riverlands is the balkans + ireland to me for sure, cat is so irish to me. i think of like south slav folk costume for them :) lots of ribbons and embroidery and intricate braiding. lilting accent
i like east asian targs :) but also like, they just arent any earthen race to me. hate when people are like "erm they cant be coloured cos they have purple eyes and silver hair?" and its like do white people have purple eyes and silver hair??????
the dornish are a mix of indian subcontinent+west asia+sephardic/mizrahi jewish+palestine+turkish+arab. the melting pot of westeros! like the daynes are jewish to me, and the rhoynar are arab/turk/'moorish'. yronwoods are white latines. sea of dorne/narrow sea evokes the mediterannean :) dornish is described as melodic and drawling, def lots of rolled Rs
stormlands is very german+eastern europe. maybe im jsut thinking of oktoberfest but i always think of them bundled up. lots of headdresses. harsh accent.
vale of arryn is very anglo to me. french/english/swiss/etc. yodelling on the mountains. sweet and sing-song accent.
westerlands is italy to me cos i like thinking of the borgias and lannisters. lannisport gives off SUCH florence/venice vibes.
the reach is again quite meditteranean to me. maybe its the wine? but i hc the tyrells as black, i think the dynamic of "upjumped stewards" compared to the "blue-blooded" hightowers, florents, etc is interesting. its why i also hc the manderlys as black, since they're from the reach :)
iron islands... obviously norse/viking, but i like pasifika headcanons too. i like asha with moko kauae and i just love if the ironborn have cultural tattooing practices. this is lessened by how they do not at all have a pacific climate lol.
