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.

Grimhilder is a loud and ill-tempered dragon. She is impatient and becomes very aggressive over small matters. She is the Alpha in her pack and rules over them with iron claws. So why don't all her pack-members try to leave, because they are loyal. These qualities make Grimhilder unpleasant to be around but they also make her a strong leader and no one dare challenges her or her pack. The need for the ability to defend one-self has also made her pack-members as strong and aggressive as she is. Thus creating a sort of balance (in an oximoronical way) within the pack.
