There are 5 races of being who developed within the World, possess consciousness, are able (at least sometimes) to live in peaceable communities and are open to the words of the Law. We call these races “The Five Kindreds” and they include: Men, Dwarves, Elves, Gnomes and Halflings. It is believed by some that once in the very distant past these all diverged from a single origin race, changing over time by the effects of magic, climate and other mysterious forces.
There are 5 races of being who only entered the world with the opening of the Hellmouth, created by embodying minor evil spirits in flesh through foul necromancy, but then reproducing in the world as normal creatures. We call these races “The Chaos Tribes” and they include: Goblins, Hobgoblins, Half-Orcs, Orcs and Hoborgs. These races can build communities of a sort, but they are usually foul and mean. Mostly, these folk serve Chaotic masters to dark ends. There are other species given over to Chaos, but whether because of small numbers (Ogres, Trolls, Ettins, Giants, Bugbears) or a different origin and lower development level (Gnolls, Kobolds, Lizardo) they are not counted among these tribes
