Swallowtail Dragons are graceful and quick flyers, much like their namesake bird. They are capable of precise aerial acrobatics, and can reach very high altitudes. Because of this, humans observing these dragons are often astonished at how large they are when confronted up close. A Swallowtail’s diet consists of insects and small mammals plentiful in temperate forests. These dragons are also made remarkable by their paper-thin wing membranes, which allow light to pass through, creating an astonishing effect on starry nights.

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.

Addicted is one of the most avoided dragon that lives in a group of male and female Swallowtails. His lineage allowed him in but the guard does not like him. The male can be short-tempered, but he always has a level of sarcasm and laughter in his voice that is malicious in nature. Ever since he joined the group, he's been flirting with every Swallowtail at random intervals, speaking vulgar words towards both males and females. Though he has a mate, it hasn't stopped the Swallowtail from harassing the other dragons. His mate sometimes even helps him, spouting scathing words towards the targeted dragons. Not many have tried to go against him, since the male is strong and can be dangerous, so most of the group just ignore his words.

Addicted likes to sometimes pop in on the dragons who were rejected from the group, scaring them and harassing them frequently. He makes things uncomfortable in-between them, since the male can see when crushes are involved and loves to speak up about them.
