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.

Sinri is a devious fellow, always out to have a good time, a fun party, and maybe play a few cruel practical jokes along the way. Many look down on Sinri for his 'backslider' attitude, but he doesn't mind. Sinri has shown his trickster and fun-loving tendencies since he was a very small hatchling and that is even how he received his name. When he was little, he often practiced his doodling skills on caves and one time he was caught by a wrinkled old dragon. Sinri was lectured on how he was going to suffer for his sins and was sent to a very strict training camp for troubled youngsters. Sinri, ever the rebel, escaped the camp and named himself after his sins just to spite the old geezer.
