When Water Dragons mature, they lose the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

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.

Unlike her adopted older sister, Aquari Neptune, Kelpie Neptune is serious and subdued.  She prefers to spend time on her own, exploring the local rivers and lakes for a potential route to the ocean, where she has always longed to be.  She doesn't speak often, but surprisingly seems to open up to the young Two-Headed female, Remark and Retaliation, for unknown reasons.  She greatly prefers the taste of deer to her standard fish, and spends hours hunkered down in the water at the edge of her lake attempting to catch them as they come to drink.  She loves listening to Avron's tales of his travels, particularly the ones involving flight over the oceans of the world.
