knucker
A species of dragon indigenous to the Waste, knuckers1[NUH·kurz] vary in color from sandy gold to reddish brown. A typical knucker community inhabits holes dug in the sand and preys on the desert mammals that wander nearby. Occasionally, if prey is scarce, they will leave their holes at night and wander into human cities in search of food. They have been known to kill and eat stray cats and dogs.2There have only been three reported cases of knuckers killing and eating a person.
