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.

Jenjei is unlike the other Waterhorses in the clan. He was born with a broken limb. As an egg, someone tossed him over a cliff lots of times until he fell into the Abandoned Area. One day Sherepta1 went out to the Abandoned Area to get new eggs when she saw Jenjei's egg. It had a big crack on it. She took it back to Mirsapia to take care of it. And that's how Jenjei's life began. He cannot walk on land, and he has trouble swimming in the water. Every dragon in the clan tried to help him, even Zharion the Healer, but there was nothing that worked. Jenjei is only allowed to live in shallow water areas. He is very calm, unlike other Waterhorses who are fun loving and playful.
