Drach'nam appear in the short story "Jade Solitare" in the compilation Tales of The New Republic. They are a very brutal and violent race employing neuronic whips (a whip with a conductive lash which sends hundreds of volts through the victim's body), and long (15") serrated knives. Their home planet is very diverse on the surface ranging from very hot to extremely cold. The planet rotates extremely slowly - one day is about two hundred earth years - so as a result all of the Drach'nam cities are dark and dank tunnels underground.
The only famous Drach'nam is Chay Praysh who is famous for employing female slaves in his palace (Mara Jade once became a slave to his brutal reigime to rescue Ja Bardrins daughter Sansia).
