Setting: desert
Species in story: Dracons, humans
Dracons: Dracons look like Dragonborn in that they have similar scales, fangs, and claws. Dracons, however, possess a tail, two horns on their head, and no wings. Furthermore, their faces are decidedly more pointed and beak-like than the Dragonborn. The Dracons have four limbs, no visible ears, fangs, three clawed toes and a spur on their heel, and four clawed fingers (including a thumb.) They are frequently colored red (by far the most common color), brown, gray, or green, Other colors exist as well, but are rare.
Female members of the Dracon race are smaller then their male counterparts. A female Dracon's chest, belly and the palms of her hands and soles of her feet are sometimes colored a shade of either white or pale yellow; all parts of the males are the same hue. Male Dracons are decidedly stronger and tougher than the females, whereas the females are well balanced and agile, as they were designed to be by the mages who created the race.
Dracon clothing is designed to be utilitarian for males, ornamental for females; Dracons never use footwear. All Dracons breathe acid regardless of what color they are. The acid generated by most Dracons isn't very powerful, but adult males can do damage with it in battle.
Dracons mature at the same rate as humans, but can live for half again as long on average. Dracons have superior vision to humans or Dragonborn, having had this aspect of their being taken directly from dragons. As such, they have darkvision and superior perception. A Dracon's eyes can be colored brown, yellow, red, blue, or green, and all Dracons have a cat-like slit for their pupils (as dragons do as well.)
