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.

Joe McCarthy.  Not quite as aptly named as he could have been, Whites being so peaceful.  Happily, Joe doesn't realize who his namesake is.  He is very talkative, and is friendly with all the dragons in the cave, although some of the shyer ones think he can be annoying.
