Pink Dragons are primarily herbivores and only eat meat during the mating season, when mates will exchange kills. When it is not breeding season, pink dragons spend most of their time incubating eggs and caring for their clan’s young. Due to their feminine color, it was traditionally thought that pink dragons were a strictly female breed, but this is not true.

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.

Rubesco is an omega male, and a member of Luna's clan. He is a hunter, and is extremely aggressive, due to teasing from his male peers about the color of his hide. When he was a hatchling, he was always being mocked, and put down by his nestmates. He tried to ignore it, but it eventually got to him. He became insecure, and then paranoid. Eventually, he went insane. Now he is mostly left alone, aside from the occasional jab. But, he usually puts an end to it fairly quickly. He just attacks, without any warning. The offender usually ends up in Luna's care for about a week.
