Cavern Lurker Dragons are nocturnal ambush predators. Although small, they are very aggressive and will attack anything weak enough to be overpowered. Their preferred method of hunting is to lie in wait in a cave, burrow, or other small, enclosed space; when any potential prey passes they will lunge out to grab hold of the unsuspecting victim and drag it back into the lair. Cavern Lurkers have an odd aversion to sunlight and almost never venture out during the day. More commonly sighted are the odd piles of bones they stack near the entrance to their dens. Their mating call is a low-pitched bumping noise.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

His name means "Black Fate". Weusi is the leader of the clan's Cavern Lurkers, taking orders from Rnachllac directly. His "soldiers" could make MwakoNgozi's black dragons pale in terror at the sight of his band of bloodthirsty killers. Being not only the largest but also the strongest of the Cavern Lurkers is more than just for show, Weusi unlike most leaders, who stand off and watch as their troops set up attacks, participates in any battle or conflict, loving to get his claws into the frenzy of a good fight.
