Humans come in all shapes and sizes. In most cases a person's homeland will
greatly dictate their appearence. If you look upon a human of tall build, pale
skin, hair of flame or straw, and eyes of hazel or blue, slow to speak, apt to
frown at cities and go wide eyed in wonder at finery or magic, you are probably
looking at a Northerner of the Sword Coast. If they had darker hair and speak
quicker they may be from the Moonsea North. Heartlanders are a diverse group
of people, usually a bit stockier and hardier if from the Dales, fine-featured
and handsome if from Cormyr or Tethyr. Add in black hair and dusky skin and
they could then be from Waterdeep, Amn, or Sembia. The folk of Calimshan on
the otherhand have dark skin from the heat of the desert. Why the gods make
humans so different only they know.
