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.

Diamond Barrior cares very much for the eggs and the hatchlings she protects. She grew up with, Haku and Hebi, Light Bringer, and Dark Bringer. She really hopes though that none of the hatchlings are as bad as Haku and Hebi were. She'll have her hands full then. Other than that there is not much to say, except for the small oddity of her tail. Instead of looking like a normal Guardian Dragon's tail it looks as if the shield part is actually made of diamond.
