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.

Those who make it to An Overwhelming Question's cave were usually led there by A Tedious Argument. She appreciates the two-headed lindwurm, whom she most likely is paying by some means. Overwhelming Question likes to play with her food, which usually begins when she casts an illusion to fake the collapse of her cave's mouth. Then she asks riddles to confound and antagonize her victims to their wits' ends. It may seem tempting to give up on these riddles, but it is ill-advised to ask, "what is it"—- that phrase alone triggers her to pounce and kill. Otherwise, she will continue playing with her food until either they decide to sleep, or figure out to walk through her illusion and outside—though if it is night, she will pursue them.

Sometimes, and Overwhelming Question likes to visit with The Room the Women Come and Go and his mate, Talking of Michelangelo. For some reason, she always calls these visits "our visit", even when talking to others.
