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.

Ren, which is Japanese and means "lotus", prefers to spend most of his time with dragon eggs or hatchlings. Consequently, he influences them, causing some of them to hatch or to evolve into male dragons.

Although he is like a father to male hatchlings, he does not care about the females at all. He believes that women are second-ranked dragons and only exist to obey the men and to breed new dragons.
