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.

Do the Creep always literally creeps out all of the dragons in EG's Cave. Creep never speaks, and always moves in an eerie, jerky kind of fashion. On dark, stormy nights many Bazara Villagers and dragons have seen this ominous looking dragon creeping around in the shadows. Hatchlings will never go anywhere near him due the fact all mother dragons advise against it since he is a very aggressive dragon.

In a private setting, Do the Creep is the leader of all Lurker dragons in EG's Cave. He leads each Lurker in ambush of prey on hunting days and has taken a very suitable mate.
