Heeby is a red female dragon. She hatched with the others from a serpent of unknown name, who had few dragon memories at the start. She does not choose her own name, but rather takes the one granted by her keeper. Mercor says that it remains to be seen whether she will grow into or be limited by the name she has accepted.
She is first of the Rain Wilds dragons to gain flight, mostly due to the urgings of her keeper to continue long hours of strength-building and practice.
