However races like Orsimer, Altmer, Argonians don't really have real world equivalents, at least I don't think. Argonians kind of resemble sub-Saharan Africans with their history and home province at least I feel, but I definetely can't see a real world equivalent for Orsimer or Altmer.
They resemble Asiatic races.
Dunmer are like Turkic / Mongolian or Chinese --->
Ashlander are like the Mongol / Turkic as they live in a Turkic tent called a Yurt. Have parallel belief to Mongol / Turkic with shamans and ancestral spirits etc. They live a lifestyle hunting with a bow in a desert land similar to that of Mongol / Turkic people.
The Morag Tong which is a Dunmer underworld organisation is made up of a Chinese word.
Orsimer are like Huns as in they are are like the Asiatic influenced races but they live amongst European type races (The Huns were from Northern China but lived and moved around Europe). The Huns like the Orsimer were described as being ugly and stocky in appearance. They bwere decribed as being terrifying in appearance and attitude. The Huns was referred to as a race who centred on being being warriors.
Argonians are more like south east Asians or Amerindians than African.
Khajiit resemble Indians (as in the country of India) ---> jungle and desert region. Names sound Indian. Big cats such as tigers and lions habitat is in India. Tigers and lions act as the symbolism used by Indian nations for themselves. etc. The Khajiits of Skyrim resemble Romani Gypsies who also have their roots from India.
