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.

Navy Blue Flame has been good friends with Forgotten Harvest ever since they were hatchlings, but Navy Blue Flame has never understood his friend's desire to freeze his growth. Ever since Forgotten Harvest became an eternal child, their relationship has been awkward. Navy Blue Flame spends less time with his friend now, and as a result he has grown lonely and sad. Although Forgotten Harvest still wants Navy Blue Flame as his friend, he can do nothing to change the situation. Navy Blue Flame, when he isn't missing Forgotten Harvest, is active and kind. He's usually an optimist, but, strangely, he's also prone to depression. One of the many mysteries of the world is how this is possible.
