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.

Downpouring Rain is the third member of her family. She is the most quiet and serene dragon of her family, only voicing her thoughts when she does not agree with something. She is usually only talkative when the weather turns cloudy and her master predicts that a storm of rain is going to brew. However, when it is extremely sunny, she droops her head until her master cheers her up by spraying her with droplets natural water from a spring. Downpouring Rain's name was inspired from when she was born. On the day she hatched, rain was pouring out from the clouds, as if it was beckoning her to come out of her shell and face the wonders of the world. Ever since then, she has always waited for the arrival of gray clouds that spray around the tears of the sky.
