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.

Sasir is energetic and graceful and has always had a passion for dancing at sunset. One evening, she saw a male swallowtail twirling beautifully and precisely, and she began to match him. As they danced closer, her heart began to beat faster. Her adrenaline spiked, and she felt that she had found her match. The moon was high as the two finished a final series of loops and corkscrews, and exhausted, glided to the ground. They decided to meet the night after and the one after that. Their intricate dances became more beautiful and more intense. And they began to fall more in love. Today, they are the happiest mates in Vyutzu-san's tribe, and have lovingly raised some hatchlings, too.
