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.

O'Zezl likes to collect awful artworks. If he acquires an artwork that is not sufficiently awful, he will make it worse with whatever he has available. Usually, it is condiments or sauces stolen from the local humans, but he also will collect and smoosh bugs onto things, throw rotten fruit at sculpture, or douse the offending non-awful work with a jar of mud. For some reason, the most horrendous pieces from his collection keep disappearing, only to suddenly all reappear in the middle of February. Often, more painting reappear than were missing in the first place. He insists that who- or what- ever does it, it is certainly not the heartstealer Ribix Lux, who is often found sneaking around his territory rather unstealthily with stolen goods. He also says that he isn't interested in finding a mate, despite the fact that she is obviously his partner.
