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.

Ptero-Madi Madas speaks only in some strange tongue which no one else can understand-- some even assert that he's not really saying anything at all. In any case, his actions, and the adventures he always seems to get himself into, testify to the fact that while he is certainly courageous, all-in-all his personality is thoroughly neutral. In fact, even the grumpiest of dragons seem to have trouble disliking him, as he's never said a bad word about anyone; or at least not one they could understand. The wiser dragons of the clan realize that this is just the way he likes it.
