Waterhorse Dragons received their name due to their horse-like physique and endearing behavior. They are capable of surviving out of water, and when on land their skin secretes a gelatinous goo to retain moisture. However, their large paddle feet are better suited for swimming, and waterhorse dragons tend to move very awkwardly when on land. Waterhorses are very friendly dragons and enjoy playing with humans.

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.

His name means Black Heart. That is because he broods much of his time and just doesn't get along with other dragons. Come breeding time he gets very picky about his mates and most of the time just doesn't end up mating. He's like this because a long time ago he had fallen in love with another dragon named Chi No Suna which means Blood Sands. He was happy and trusted her with his life, but she betrayed him in the end.
