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.

This dragon, despite her dark appearance, considers herself a force for order in the Cave. She preys on wrongdoers, whether they have violated the laws laid down by the clans or her own personal code. Though small, she is surprisingly strong and aggressive and wins many of her battles simply by refusing to quit. "Meh, I can take her," is a common sentiment expressed by her targets, but it is also frequently their last words. She features heavily in Wildbow's story, Wyrm, and has struck up a surprising friendship with the Sunstone dragon.

Wildbow first met her when she was a small hatchling, practicing her stalking in the shady woods. He was wandering through the forest near his cave, when a small dark blur pounced on his tail. Surprised, he inquired as to the hatchling's name. She looked back at him, a serious expression on her face. "I am She Who Skitters in Shadows," she said, adding as an afterthought, "but you may call me Skitter."
