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.

Xavis is a very silent and calm dragon, and is the official guardian of the cave. He is overly protective of his children and mate, Duskrose, and often gets into arguments with her other, more violent mate, Jypsom. He is happy being with Ezarana, Kwiko, Gaeva, and Vasper but unresponsive towards others. He especially has a soft spot towards Ezarana, but most dragons of the cave do too. After having many children, he has settled down and is now sometimes off-duty, letting Topazfyre and Taurom, his two feisty twins, guard the cave.
