Sunset Dragons are closely related to sunrise dragons. However, their behaviors differ greatly. Sunset Dragons generally live alone or in small packs. They are more active in the evening, hunting and performing all of their daily tasks as the sun sets.

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.

Nightberry is a slightly insane dragon.  Though normally he'll try to be calm, at completely random times he'll suddenly scream something such as "COW PIEBALLS!"  He will then grin in an unstable manner and either fall over or attempt to fly away, fail, and then fall over.  Once, he even tried to devour someone else's cheese dragon, but  Nightberry was swiftly tackled and held down until he regained sanity.
