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.

Crocus was a nomad dragon for a long time, migrating from cave to cave every night, hunting for prey and adventures. One night, when attracted by the scent of a female, he broke into a cave occupied by a couple of dragons.

Despite being the smallest in size, he was the one who fought and defeated Hyacintho, stealing the heart of Dampnas who was amazed by his strength and skill, after humiliating and driving out the other defeated male from the cave, he took up residence there, becoming also the permanent mate of Dampnas.
