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.

Sengal thinks vastly different from other dragons. Although most dragons tend to think "danger" when an angry spitfire approaches, Sengal thinks "Bunny Rabbit" and attempts to hug. His innocent view of the world often leads him into trouble. His hyperactive demeanour and slight lisp set him apart from other nocturne dragons. It is believed he may have a disorder, but he's able to function as normally as other dragons. Sengal tends to follow Darth around quite a lot and adores Mini Darth.
