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.

A gentle soul at heart, Ageku loves the sound of soft falling rain. During the springtime, he will purposely seek out sudden rainstorms in the forests and jungles, sometimes practicing his magical abilities by redirecting raindrops into patterns that form flowery designs when the rain hits the ground. On days when sunlight shines through the rainclouds, Ageku tries to hold the raindrops in a way to create a rainbow. He has managed this only twice so far, in isolated locations, but hopes that one day he can teach his siblings or his children his abilities, and they can create a rainbow that reaches across entire biomes.
