While not actually split into subraces, humans are as varied on Shem as they are on Earth. Here's some of the Shemmish break down:

• Palhuric: North America is central Palhur, with western Palhur having some Gulf Coast features and Australian.
• Taggaran: Taggarus is African.
• Matian: Mati is the Iberian Peninsula, Latin America, and the Middle East.
• Dabusenese: Dabusen is Asian.
• Jesenya: Jesenya is western and central Europe.
• Ranic: Ranu is eastern European.

• Reever Sea and Island Bridge: Caribbean and Oceania.
• Lyrillan: western Europe, Caribbean, Polynesian, and Scandinavian.
• Ansulymic: settled by people from all over.
• Fasunic: settled by people from all over.

And many more. Any Earth-based ethnic group, race, or nationality can be or is reproduced on Shem. Consult your GM.
