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.

Bella Swan is a Mary Sue is a ferociously proud Shield dragon who, upon overhearing a conversation about the last twilight book, became infuriated at the discovery that the useless, whinny protagonist had the ability to "shield" everyone around her. Flying into a fit of rage the shield dragon ate the angst filled teenagers and burned all of the Twilight memorabilia littering the ground. She vowed to always protect the American language by burning every copy of Twilight that she could get her claws on.

If you like Twilight, she won't eat you, but if you dare to try and corrupt the hatchlings in her cave with it, or try to explain how "useful" Bella Swan is, she will quickly turn on her attack mode.
