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.

Ketharo is known around his habitat as the tribe's most powerful healer. He uses his tears to heal wounds and feathers from his wings to use as bandages. He likes to please people with his cheerful personality, and always wakes up in the morning with a smile on his face.

Since his childhood was not as good as people expect because of his personality, he hides his wounds and mental scars by telling the hatchlings stories and play with the sick dragons. He cares very much for his tribe, and as a healer, he thinks that "a family's safety is more important than an enemy's defeat."
