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.

Rosa Nuria's bright, pink egg was found by the human Ember, which she brought to her house on the highest mountain of Elgar. After Rosa hatched, Ember announced to the other dragons on the mountain that she believed this would be the last dragon she would raise. Dragon eggs were becoming sparse on the mountain, and Ember had no need of searching for eggs in other places since more and more people were raising dragons. As a result, Rosa became very spoiled. The other dragon crowded around the little hatchling; giving her anything she might want or need. All the dragons wanted to hold her. Aashini, the guardian of the hatchlings, made it her duty to guard her. Even Samson, the fiery tempered sunstone dragon, was soft towards her. However, once Rosa grew up, the other dragons did not seem as nice to her. They were having children, and she was no longer the littlest one.  Instead of being the baby of the family, she became' little sister', and the nickname has stuck ever since.
