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.

Breathless Stone was one of the First Five. She mainly stays in the nursery and watches over the hatchlings and eggs. Even though she is "asleep" during the day, she still sees what goes on, so that if a hatchling gets out or is taken, she would know, or if an egg hatched during the day, she would get to still see it. Her heart is broken because none of her children are in the clan, though she is sometimes able to visit a few of them.
