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.

Olten has no sense of adventure whatsoever, and would rather stay home than do anything else.  Even the thought of leaving his cave to treat patients, and those needing treatment must somehow come to him.  Quite how the child of Dysi and Dayr got to be this way is a mystery, though it's probably because of all the dangerous situations he likely found himself in while growing up.
