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.

Being the most important of The Cave's clan of Guardians, Master's Estate Guardian prides himself on being the only true guardian dragon in the clan. He has been given the most important position in The Cave: guarding the master's estate. EG chose him because of his beautiful and important lineage and his powerful armor-like scales and vicious-looking claws capable of scaring away anybody.

Master's Estate Guardian is given the specific duties of guarding the perimeter of EG's estate, her docks on Cumberland Lake, and  the border of her estate and Bazara Village lines to prevent the intrusion of nosy villagers or harmful and viscous dragons. He is only permitted to admit any dragon or person who knows a certain complicated password that is changed once a month.

Despite his immensely important duties that bear down on his regal shoulders, Master's Estate Guardian is calm, friendly, and sociable to all who know him and wouldn't hurt any creature that does not threaten his perimeters.
