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.

Taking after her father, Thretti began learning about healing very early on in her life, devoting every second of her day to her studies. However, since her father's clan already had a healer, she was not needed. Her early days as a healer were spent in Nahkii's clan, where she would study and learn more about medicine, and take care of the sick. Eventually, she had become skilled enough that King Ramh Droighionn II himself asked her to become his royal healer. Obviously, she accepted. Although she now lives in his empire, she still heals the dragons of Nahkii's clan whenever she is needed.
