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.

Jarlaxle is a rather flamboyant dragon. While still having traits related to his species, such as his claw happy nature and obsession with hoarding, Jarlaxle has a charismatic personality.

Whenever he goes out at night, the dragon is decked out with tons of necklaces and bracelets. Tied around his neck is a rainbow colored cape, which he likes to fling around in others faces. He attempts to wear bright colored vests and has a huge hat with a large feather poking out of it. He usually introduces himself to others with a bold bow and smooth, polite voice.

This makes other dragons underestimate him, but Jarlaxle is incredibly dangerous. His claws have serrated edges and he moves with lightning speed. He uses his abilities to take jobs from less savory types of beings, acting as a mercenary.

Sometimes Jarlaxle takes jobs that have him partner with an assassin named Artemis Entreri, a grumpy Black who Jarlaxle takes joy in agitating.
