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.

Quarkheiler has been assigned as the healer for the Ashdragons in Laura-Lana's clan. Despite their gentle nature, Ashdragons don't have a lot to fear, so Quarkheiler has a lot of time to sit around and be bored. He usually cheers himself up by visiting other White Dragons and making a nuisance of himself.
