It was previously believed that purple dragons were exclusively female, but this is not the case. Recent environmental shifts have revealed the existence of both genders of this breed. Female behavior is well known; they are primarily herbivores but will eat meat during mating season. On the other hand, very little is known about the behavior and habits of male purple dragons.

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.

Haeranth's personality is different from most of his clan. He thinks he's the most magnificent male around, and enjoys bossing other dragons. He wishes to claim the position of clan leader, along with Alaessa and Aleesta.

Haeranth prefers being around pink dragons, especially Hakkranth and ones of his own kind.

The human caretaker, bwaaderent (who prefers being called Rosi), is the rider of Haeranth.
