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.

Shieluk is one of the two guardians of the cave. She rarely says a word, instead giving a quick swipe of her claw to any dragon that is cruel or making trouble. She always remains perched at the mouth of the cave, eating animals that other dragons bring to her and surveying the land. She also serves as one of Illuminor's henchmen when off-duty. Being a guardian dragon, Shieluk refrains from joining the pushy army forming near the lake. Even though raiding villages may be more exciting than her current post, Shieluk stays firm in her decision.
