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.

The cavern Surizako occupies is due to a calculated choice on her part. While it is far from the largest or coziest or most tactically secure spot, her living space happens to be the perfect distance from a particular river that runs rich with liquid mana. The river, which is frequently visited by larger prey, is surrounded by cliffsides and hills with plenty of small nooks that make it easy for Surizako to quickly ambush her dinner. The bone remains of these meals are, naturally, stacked outside her lair. Due to the mana deposits within the river, the bones of the animals who drink from it will glow during the darker nights. Surizako takes a fiendish pleasure in the unsettling beauty of the sight, and is constantly on the lookout for any interlopers who might try to pilfer from her home.
