"Humans are fools and hopelessly naive as well. They outnumber us; they are everywhere, and yet they have no more sense of their strength than a rat. Let us hope that the Datto stay that way." - Dukkoti Nightrunner, elven warrior
Humans are the dominant culture in the explored parts of Athas, known for their versatility and adaptability. Most tend to be ambitious and individualistic; even the tyranny of sorcerer-kings hasn't stamped out this diversity. Other races often don't know what to expect when meeting a human for the first time because predicting their behavior based on cultural norms is difficult. "It's human nature" is a common saying when humans appear to take action for no apparent reason.
Humans tend to get along with races they co-mingle with (most often dwarves and muls). Half-giants and thri-kreen are seen as dangerous monsters. Elves and half-elves are considered flighty and untrustworthy. Halflings are exotics. Humans often serve as go-between when one race deals with another.
Men average around 6 feet tall and 200 pounds while women range around 5 1/2 feet tall and 140 pounds. They tend to be dark-skin and bronzed tones with darker hair, though all colors exist with nobility tending to the greatest variety. Humans are prone to mutations, and it is not uncommon to find exaggerated features such as webbed feet, or even extra digits on hands or feet.
Centuries of abusive magic have taken their toll on the human body. Some humans have marked alterations to their appearance, such as bizarre symmetry, exaggerated facial feature, pointed ears, no facial hair, unusual skin colorations, etc. Humans are familiar with this and generally unsurprised by such differences. Ultimately, these give no benefits or hindrances in gameplay and are for flavor.
Humans are hard to generalize.
