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.

Tixerrus is a rather sickly young dragoness, becoming ill as an egg and staying so through her hatchlinghood. She is forced to stay inside of her cave at all times, but is too weak to lunge out at any unsuspecting prey. Every day, she wakes up with a gift at the entrance to her cave, usually a deer that has been killed and left for her. Although she doesn't know who the mysterious meal gifter is, she respects and loves the dragon with all of her heart. The only clue she's found to the possible donor is the appearance of tiny icicles hanging from the deer's body.
