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.

Xerionii is second in command when it comes to healing around his cave. Closely studying Veldin's scrolls (when she isn't around), he has learned many things to help him become very skilled. Xerionii also harbors a strange attraction to Veldin, even though she is his own mother; he wants so desperately to nurture children with her.

Xerionii is somewhat of a stalker with some of the other crushes he has in his cave, constantly going through other female dragons' belongings.
