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.

Erithio has an intense passion to help humans and animals alike when they are injured. If someone is injured beyond the medical knowledge of humans, he will use his powers to heal them.  If a hatchling has a little cut, he heals that as well.  Although he doesn't know anything about medical stuff or medicine, but with his powers, he really doesn't need to.  Of course being a pacifist, he could never consciously attack anyone.  He'd gladly risk his own life if it means saving that of another.
