Nocturne Dragons are a strange breed. Whenever light strikes their bodies, they are frozen in whatever position they were in. This leaves them vulnerable and they rely on camouflage to keep themselves safe. They are often mistaken for statues when in this frozen state, but Nocturne dragons do not actually turn into stone. Rather, they merely idle until the sun goes down. At night, these dragons come to life, proving themselves to be powerful fliers, although little else is known about their true behavior.

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.

Xum (Zoom), being a nocturnal dragon, does her utmost to avoid light whenever she can. She hates being still, unable to move, until the light releases her. True, the nocturnal section of the cave is by far the darkest, both day and night, but there are torches everywhere else. They light up the cave at night and a stray beam of torchlight can freeze an unwary nocturnal in its tracks. The very idea of being forced to sit still for hours on end agitates her so much that she often hides in one of the unused parts of Kanaye's cave. True, she can't do much while she hides, but at least she still has the use of all her limbs.
