Race mixes biology and culture, then translates those concepts into racial traits. Yet since both biology and culture are mutable—especially when one considers the powerful forces of magic—racial traits can be so diverse that two creatures of the same race can be extremely different while still manifesting aspects of their shared heritage and culture. A race's traits, its history, its relations with other races, and the culture that all of these things imply—all of these frame your character. This is true whether you play to or against the stereotypes.
