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.

Leriah, named after her mother, Lorelesia, is the eldest of Sorrin and Lori's children. She had no siblings as a hatchling. Her hatch-mates were Leonorix, her cousin, Emnaress, who would later become his Mate, and Gnot, the Pygmy Dragon. For a time, the four were inseparable. Leriah and Emmie are still best friends, but Gnot has drawn away from the other dragons, submerging himself in his father's miniature Clan. Leriah has always been curious. This tendency has gotten her into more than her fair-share of trouble. She is a talented singer, and is often heard humming. Sometimes you can determine her mood by the tune. At her birth, her father announced that she would be the heir to the Clan-Leader title. Leriah will be the first female Clan-Leader of the Valley Clan. Every day she endures hours of lessons. She has many teachers. When they become too much, she often goes out flying. It gives her a freedom that nothing else can.
