Ridgewing Dragons live just below the snow level on the upper slopes of mountains. They are a friendly, playful breed and enjoy dancing in wind currents near their homes or plummeting down into valleys from great heights. Their wings, by far their most striking feature, grow in fin-like ridges along their backs. While their bodies lack markings to blend better with their surroundings, a ridgewing’s wings have bright markings in the colors of the flowers that grow in their mountain habitat. Occasionally different-colored individuals can be found, but they are rare because their striking coloring offers little protection.

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.

Nathan is normally silent, and likes to spend his time alone. He usually doesn't talk to anyone, and isn't very sociable. He was abandoned as a hatchling, so he finds it difficult to trust anyone. He likes to blend in with the scenery, and pretend he doesn't exist. He normally doesn't start conversations, and most dragons don't bother to talk to him. He wishes to have children one day, but doubts that will ever happen. He occasionally talks to Sorrow, because he has a crush on her, but he knows that Sorrow loves Splash, and that Splash loves Sorrow. He feels sad about this, and thinks about things like this when he's alone.
