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.

LennonMcCartney possesses a strange multi-personality disorder of some sort. At one moment, he claims to be one way, and the other moment, he claims to be a totally different dragon. For example, one day he may claim that he is a connoisseur of certain pebbles found at the bottom of the creek that he often plays in, but when another dragon mentions those same pebbles the next day, he will claim to have never said such a thing, and may even claim that he has never seen the dragon addressing him in his entire life! However, even days later, he may come across the very same dragon and once again bring up another anecdote about his pebbles. No dragons ever really know for sure what goes through LennonMcCartney's bizarre mind, and many don't ever want to find out.
