Orcs: Orcs are thugs, plain and simple. They live short, brutish, primitive lives, taking what they want and usually dying for it when caught by the owner (particularly if that owner was also an orc). They are tall, muscular folk with a penchant for slow thought and less precise application of what little knowledge they have. Their skin is a muted brown or green. Their hair is black, sometimes with a green tinge. Their eyes are usually black. Other races find them useful as cheap guards. When a group has managed to organize into a regular band (for banditry or mercenary reasons) their chaotic fighting is a force to be reckoned with.
Kobolds: Kobolds resemble bi-pedal dog/lizard hybrids. They are short (under 3') and scaly. The scales of most kobolds are brown or green, but red, blue, and orange also show up. Kobolds are very thin, especially in their limbs, but they are quick and wirely. They are devoted and hardworking, but hold grudges for generations. They are also not generally considered very smart, though they do have natural talents for both trap making and magic, often finding creative ways for application.
Furleens: More commonly called cat-girls, furleens look like other races, most often humans or elves, and less commonly Halflings, with the ears and tail of a cat. Some also have "paws" instead of hands or feet. They have a tendency to say odd words like "kawai" and adding "san" or "chan" to the end of nouns. They also have a tendency toward looking pretty and innocent, and generally being useless.
Changelings: Changelings were long thought to be lycanthropes, and it was only in recent years that it was discovered that their ability to change shape is genetic, not viral. Most changelings can assume the form of a human (or other humanoid) and that of a quadruped like a wolf or bear, as well as an intermediary shape. However, other animal shapes are possible, and the rare changeling can even assume more than one animal form.
Illumans: Illumans are essentially humans with a deeply racial psychic ability. Often strange, glowing shapes or characters float around their head. Illumans say these shapes grant them powers. Illumans are universally bald. They grow no hair at all. Otherwise they look and act like humans, but with a touch of the superiority expressed by the elves.
Giants: Giants stand 9-12 feet tall. They look like humans, but they like to use their size to intimidate and play pranks on people. People rarely like to be near giants, since they constantly refer to people around them as "little siblings" and comment on how small everything near them is. The consider Halflings and kobolds to be "pocket sized." For all their focus on size, giants tend to be less athletic and focus more on introspective philosophy.
Fairies: Fairies are between 6-18 inches tall. They have useful wings, which take all manner of shapes, though the most common are like those found on dragonflies, butterflies, or birds. Other shapes are often considered exotic and often even erotic, fairies with these wings are usually celebrities. Hair, skin, and eyes are usually bold and bright colors that stand out: orange, green, pink, and so forth. Fairies seem to be immune to weather changes, and wear only light garments when they wear anything at all. They are fond of practical jokes, and while few are capable of actual magic, most have one or two "magic tricks" they can use.
'Structs: Structs are manufactured beings. It is only very recently that their self-will has been recognized. Structs are usually made from magically animated metal, but other materials are also used, such as clay, straw, or stone. Structs are logical and ponderous, but also have unmatched strength and precision. They are made to take a lot of damage. Because they are manufactured, all manner of appearances and sizes are possible. It is now illegal to make a Struct unless you are a Struct.
