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.

Always racing, always dashing through the currents, Covella loves every bit of aquatic games. She'll speed through the waters to finish first or grab a beach ball to score a goal at the opposite end... Even if she is the only one playing. Her days are filled with activities with others and ones that she made up herself to fill her time up. If she sees someone nearby watching her and she's not playing with others, she'll always come to shore and try to nudge the person to the water. This isn't meant just to play, though. She feels very uncomfortable and out of place when away from the water. The further the distance from the currents, the more timid and shy she becomes, even avoiding people when she is too far for her preference. Though she'll be somewhat upset if the person is too busy to talk or play, she will understand if it's for a good reason (unlike what Elosh offers). If anyone has the time to stop by, though, Covella will definitely appreciate the visit.
