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 her name implies, Medical Guardian is the dedicated guardian and the last line of defense for the clan's medical team. While the spotlight is almost always on the efficient and prestigious medical team, few remember that it is the presence of Medical Guardian that carries the worry of sudden attacks away from the medical team during frontline field work, allowing them to work with their best. These few, including the entire medical team itself, will always be thankful to Medical Guardian for taking up this unthanked but absolutely crucial position.
