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.

Hatched in winter, Teresinha grew up when few other hatchlings did. She helped to heal those other dragons that were wounded from frostbite, despite her tender age. Dwelling in a cave above a treacherous mountain pass, she aids those who have succumbed to the dangers of the mountains. Creatures she has healed bring food to her (although if she is hungry and no one comes to feed her, she eats the stunted plants of alpine terrain). She had a short dalliance with the autumn dragon known as Ulrik, and laid only one egg. The egg looks like it will hatch a winter dragon, which seems fitting in Teresinha's snowy home.
