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.

Hakubya, which stands for Thousand White,  is a very wise dragon... and pretty mysterious as well.

Although his magic and healing power are great, he refuses to lend his services without any trading fees (an eye for an eye,a tooth for a tooth).

It means that if you ever lend him a hand before, he'll pay the favor back.

And the same applies to if he ever helped you out of a tight spot, you would have to repay the favor.

And if you don't,his spells could have a backfiring effect with them since he doesn't intends to let you go for nothing in return. This kind of spell is problematic but that shows what kind of nature he has.

He and the Scroll Owner have a very tight relationship, but what kind of relationship it is is unknown. And anybody who tried to investigate this fact are vanished without a trace.
