Golden Wyverns are known for their beautiful metallic scales and rumored magical abilities. Living high in the mountains, these dragons do not believe in killing for sport or pleasure. They will hunt only when hungry and defend themselves when provoked, but will avoid killing to the best of their abilities. Golden Wyverns often mingle with other dragons of similar color and take pride in their shimmering hide.

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.

Jonathan was raised alongside a Caligene dragon named Dio. While Dio is cruel and evil, Jonathan is very kind and gentle to everyone he meets, to the point that he seems to be incapable of feeling true hatred towards anyone, no matter what kind of a person they are. He can sometimes be a little hot-headed, getting into fights with some of the meaner dragons in the clan, but ultimately he's a pacifistic person. Jonathan loves to read and is a keen student of history.

His one and only mate is Lady Erina, a Mistletoe dragon he met as a hatchling. Jonathan is so devoted to Erina that he refuses to take any other mates.
