And finally, here are all the races, with their relative heights.

Finally, the Grimir - the 'orcs' of Ukadarlia. They have grey skin and protruding lower canines. They are otherwise another human variant. Both the Aeifa and Grimir can interbreed with each other and the other human ethnicities; however, the pregnancies are likely to miscarry about 50% of the time, and the progeny have about a 20% chance of a genetic flaw - eg cleft lip, club foot, extra digit, accessory nipples, large birthmarks, etc.

The Aeifa - 'elves' of Ukadarlia. These really are just a human variant, though more so than the other human ethnic groups. They have purple eyes, and can see into the UV range; they nearly always have red hair; and are very tall and very thin. They have extended life spans up to 300 years, due to biochemical changes that slow aging.

The Davaraz - the 'dwarves' of Ukadarlia. They are albino with green cat's eyes and night vison. They are also radio-resistant, and love using uranium and cobalt in their metal work! They predate human arrival on Dashamargo by about 15,000 years at least, and are from another planet, not earth. And so cannot interbreed with human stock - hence no half-dwarves or half-davaraz.
