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.

As a Guardian Dragon and the oldest male dragon in the cave, Dragon Slicer would sit on its favorite rock directly outside of the cave. If anything comes near the cave other than dragons that originated from the cave or that was raised with it, or eggs, he would attack anything that shows a threat even other dragons. He has defended the cave from so many dragons by slicing them with his tail, is what earned him his name Dragon Slicer.
