The Promise of Dragons
Kobolds are (very) distant relatives to dragons. These small beings will fall right in line with any draconic relative deemed to have a higher purpose.
Kobolds are extremely fecund egg-layers, having the highest birth rate (and death rate) of all humanoid species.
Unlike dragons, kobolds are cold-blooded. The scales covering their bodies are like that of an iguana or other large lizard. The scales that cover their tails are very fine, so that they resemble the naked tails of rats. Kobolds lose and gain new teeth throughout their lives, often saving and making necklaces from them. Kobolds favor raggedy-looking red or orange clothing made from leather or the silk of giant spiders. They never wear shoes, but they are fond of jewelry and other ornamentation.
