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.

Lurker's favorite time of year is Halloween. Frights and fun! Monster sightings! Indiscriminate killing! This is the only time he can frolic and frisk with evil spirits without others casting judgment upon him. He can mosey around town without any sort of disguise and maim and murder whomever he pleases, his victims having no idea he is a monster for real. There's a great big supply of unsuspecting meat, just waiting for Lurker to feast on them. Halloween! What a time for him to be alive! And what a time for everyone else to be dead.
