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.

Takashi assumed control of Damian's Island Clan after their escape from the Crater Clan and watches over his comrades with almost fanatical enthusiasm. He considers himself a paragon of virtue and morality, and getting him to change his mind once he has made a decision is nearly impossible. His assuredness in himself has begun to stray into arrogance and blind ambition, as he believes he can do no wrong. While he does not use and abuse his fellow dragons like the Crater Clan's warlord, Wu the Black-Capped Teimarr, he will still send them into dangerous situations on nothing more than confidence in himself, leaving some to question if life on the Island under Takashi is much better than life in the Crater.
