White Dragons are pacifists and specialize in extremely strong healing magic. The only limit of this magic is that it can’t bring back the dead. They only eat plants and never kill living things.

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.

Heaven's Oath is Ayael's best friend. She is calm and peaceful, although she's not shy, and her hobby is to watch the hatchlings playing and heal them when they are hurt. Heaven's Oath is one of the four oldest dragons in the cave along with Shemech, Hiervan and Shura, so she saw all of the dragons that live there grow up, and this is why they respect her as if she was their mother.
