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.

Njordr, like his mother Osun, is an ocean dragon who loves to voyage far and wide. Unlike Osun, who prefers warm tropical waters, he enjoys the colder waters of the northern seas, and often voyages as far as the Arctic Circle in his explorations. He is a bit mischievous, sometimes even deadly dangerous to humans, but has a firm sense of justice, and his actions are usually motivated by a desire to see good prevail and evil be punished (by his own definitions of good and evil). He might, for example, swamp a slaving ship (rescuing as many of the captured slaves as he can) one day and nudge a troubled merchant vessel into port the next. Sailors often drop him offerings of meat in hopes of winning his favor and help, or at least avoiding his ill-will.
