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.

When Lady Luck's egg was found, it was something of a miracle; it was the dead of winter, and she spent far too long in the cold, her egg nearly freezing to death. Nonetheless, she hatched and grew into a healthy dragon. Many of her cave-mates noticed that she seemed to be a very lucky dragon, always finding interesting things or escaping dangerous situations completely unharmed, even when she was just a tiny hatchling with fragile wings. She's always dismissed this as superstition, and so hates her name; she refuses to respond to anything but "The Lady".

The strange thing is, bad things seem to happen to those who call her Lady Luck against her wishes...
