Guardian Dragons have large shields on the end of their tails. Although the shields appear to be heavy, they are light, yet nearly unbreakable. Guardian Dragons use their tail-shields, as well as their wings, to deflect attacks and protect others. Often, they will guard the eggs and hatchlings of a nest while others are away. They are generally peaceful, and will not retaliate unless necessary. They have no need to forage or hunt, as they are fed by those they protect.

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.

Sudden Flame's self-confidence suffered a terrible blow when he wasn't able to protect three eggs entrusted to his care. He has never cared for any eggs since, but considers it his duty to keep a strict watch over the dragon responsible for the earthquake that killed the eggs. Although he is exceedingly proud of his first own egg, he accepted its mother's decision to abandon it, knowing that others are better able to keep it safe than he is.
