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.

Osoria is famous. Ever since she defeated the rage-filled Osirodon, she was a hero. Only, she didn't ever want to be a hero for doing that. Actually, that was the thing she didn't want to do. It broke her inside because Osirodon was her brother. Something had happened when he went out one day and when he came back, he was pure evil. Osoria had tracked him down and killed him because of all he was doing. Today, she doesn't do anything and sits apart from the other dragons. Except for her sister Xenina, all the other dragons of her cave keep a clear distance out of respect for her sorrow. Xenina, her older sister, stands by her and comforts her. Osoria will, unfortunately, be filled with sorrow and grief for the rest of her life. She does have the will to live, but she is sad.
