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.

Heaven's Guardian was a soldier during the great war of her home land. Her job was to protect the Ministry and its White magic while the Red and Black dragons soaked the ground in blood. Among the magic dragons was a young healer named Heaven's Promise, whom she fell in love with. His mother did not approve and plotted to have Heaven's Guardian killed. She had almost succeeded but Trinity Horcus of the Starless clan found her and healed her. Now Guardian is once again a soldier and Promise is at her side with their family.
