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.

Zeus is the grandson of Bellerophon, and has received the same title as him. His grandfather's trait has passed on to him, so Zeus is extremely flirty. And, like his grandfather, he has beautiful colors and scales. Once he had gone to a shimmering river to get clean, and it just so happened that the Soulpeace hatchling that Bellerophon had so embarrassingly came to court was now an adult, and she was reading by the side of the river. "Oh, hello there." he said. "You're quite beautiful, and smart from what I hear." She smirked, and closed her book. "So, what are you trying to do, flirt and try to make me yours like so many other dragonesses before me." Zeus was extremely confused. No dragoness had ever mentioned it, nor openly cared. "Well, I feel something different. You would be my light." The Soulpeace sighed. "If you wish to court me, you may, but be warned: I am no idiot." Zeus smiled. He went on to breed with her, and they had a little egg.
