My world has no humans or related species. The three sentient races live and work in symbiosis.
Dracans: Bipedal reptiles with large wings on their backs. They use their tails for balance when standing, like a kangaroo. Kewpies: Like elves evolved from insect ancestors -- slim, delicate bipeds. They have long antennae to sense air movement with, and are built entirely for fleeing danger instead of fighting. Ferrin: Sentient, housecat-sized weasels. They have excellent hearing and commonly act as live-in help to the other races.
