Undine Dragons are named for the water spirits with which they share territory. They have close relationships with these spirits, and are able to communicate with them. In exchange for protection and respect of their mutual freshwater homes, laid eggs are often protected by a blessing. This blessing stays with the dragon into adulthood, and with it they gain potent magical abilities. Sometimes when an Undine Dragon becomes very upset, the ground at their feet may frost over or begin to steam. They have also been observed to manipulate water directly, rerouting raindrops or creating puddles from groundwater. Undine Dragons always live near forest pools, streams, or waterfalls. Both genders take equal part in the raising of young and are very good parents—though they may not remain mated after the offspring are grown.

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.

Banjo is not the most well-meaning dragon. He likes to try and steal from other dragons and even humans on occasion. He did not learn how to control his magical abilities, and whenever one of his heists goes well, he gets excited and the water around him starts acting wildly. The water often leads others to him and he has never been able to complete a heist. After a failed heist, Banjo likes to hide behind his favorite waterfall.

Banjo has a flair for the dramatic. While this can be seen in his elaborate, failed heists, it can also be seen in the plays he enjoys putting on for hatchlings. Although Banjo would adore being a father, female dragons are reluctant to mate with him because of his criminal aspirations. It does not stop him from playing with the hatchlings.
