In their own tongue, they call themselves the DroCh.  “Ch” is used to represent a voiceless uvular fricative, a sound that does not exist in the common trade languages but is common in the language of the DroCh (also known as DroChlaCh).  They are an isolated people that have little contact with other races, but when that contact does occur, they are referred to as either “Dwarfs” or “Dragons”.  As a species, they are an example of extreme sexual dimorphism and a resulting high degree of division of labor along the lines of sex.
