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.

Sir Periwinkle has a carefree, light-hearted personality. He loves to fly inside the cave as well as outside. Generally, he is friendly, but he seems to be afraid of his tamer's Hellfire Wyvern, Diablo. While Diablo has not actually hurt or approached Periwinkle in a threatening manner, the Pink remains evasive. This dragon likes to follow Violet Sage of Forest when he goes on small journeys to collect interesting objects. While most dragons are hoarders to some extent, Periwinkle is far more interested in looking at Sage's collection than building one of his own. Generally, the older Purple Dragon has no trouble with the young Periwinkle gazing upon his collection.
